Ultimaker white paper Setup tosuccess:3D printing for manufacturers6 11 15IntroductionIn manufacturing, time is money. With a 3D printer, jigs, fixtures, and other tools can be produced on demand, on location. This means faster machine setup, less variation during assembly and fitting, and smoother production processes.What you will learnThis guide will help you achieve the benefits of 3D printing as quickly as possible. Using Ultimaker fused filament fabrication (FFF) printers as examples, we will look at:• How to set up your printer and optimize your workspace• How to implement a 3D printing workflow• How to make the most of 3D printing, with application ideasThis guide has been created by Ultimaker’s 3D printing experts. It features examples from real-life manufacturers, so you can learn from those already using 3D printing to reduce production time and costs.SetupTo start using your 3D printer as quickly as possible, you should consider a few things in advance. How is it installed? Where will it be located? Who will use it?UnboxingBefore your 3D printer arrives, visit for useful resources, or watch one of our videos to help you understand your printer’s features and guide you through setup (e.g. the features explained and unboxing videos for the Ultimaker S5).Each Ultimaker printer comes with a quick-start guide detailing how to unpack and install the printer, and start your first print. The first time you turn your printer on, it will ask you to complete simple setup actions: choose the language, install the build plate and printcores, load material, connect to a network (optional), and check for the latest firmware.LocationDesktop 3D printers are considered clean and safe for an office environment, depending on the material being printed, and are quiet enough to be placed on a desk. But if a single 3D printer serves multiple users, or you have a multi-3D printer setup, it may be best to create a central 3D printing area.As Ultimaker 3D printers do not exceed a maximum noise level of 50dB, noise isn’t usually a problem when running a single printer. But when running multiple 3D printers it is better to place them in a separate area to reduce overall noise levels.Ventilation should be considered when using materials with safety requirements, or which produce an unpleasant odor. You could also consider an air management accessory, such as the Ultimaker S5 Air Manager, which removes up to 95% of ultrafine particles (UFPs). Ultimaker provides safety data sheets for every Ultimaker material, so you can identify each materials’ safety requirements.OperationUltimaker 3D printers are designed to ensure reliability and maximum uptime, and are certified for safe unattended use. This means that you can leave your printers to run unattended, for maximum efficiency.Files can be uploaded to the 3D printer via USB or a network connection. With Ultimaker Connect and Ultimaker Cloud, you can start and manage print jobs remotely, access print analytics, and save your print settings to the cloud for remote access.PersonnelUltimaker 3D printers are designed to be simple to use, so you’re unlikely to need specialist training or a new team member to use them. You may, however, need a dedicated operator when running more than 10 printers.To optimize results, staff should be trained to design for additive manufacturing (DfAM).A good introduction to this concept is our free ‘How to design for FFF 3D printing’ guide. Your reseller may offer more in-depth training.Once your team and workspace are ready for 3D printing, it’s time to implement a workflow that streamlines production.WorkflowMaterial selectionMaterial selection is critical to a successful 3D print. Ultimaker 3D printers are optimizedto use the Ultimaker range of materials, but can also use third-party materials. Many material manufacturers provide print profiles for their filaments in Ultimaker Cura, for optimal print results.Here are a few of the most popular materials:• Tough PLA offers good impact resistance with the affordability, speed, and easy-printing of a PLA filament – a great choice for robust, just-in-time tooling • Nylon can be used to create strong parts that also offer abrasion resistance and low friction, perfect for quality assurance gauges that need to be used repeatedly• TPU 95A is a semi-flexible, rubber-like material and can be used to add protective surfaces to toolsMore information on choosing the right material can be found on the Ul timaker website3D modelingWhen designing for 3D printing, there are seven key considerations based on the geometry and features of your part:1. Nozzle size. Consider the diameter of the nozzle you use. The minimum wall thicknessof your part should be equal to or larger than your nozzle’s diameter2. Bottom layer. The bottom layer is the foundation of your 3D print. The larger its surfacearea, the better its adhesion to the printer build plate. Use chamfers insteadof fillets for edges that touch the build plate, as rounded corners are more effective than sharp ones3. Support material. Dual extrusion printers can print support material within overhangsor cavities to enable more complex geometries. This does, however, increase print and material costs. Limit the use of support material by creating overhangs with an angle greater than 45-degrees4. Small details. For designs featuring small details, use a smaller nozzle. Ensure thatsmall details have time to cool before the next layer is printed5. Tolerances. Plastic polymers shrink when heated and then cooled. This needs to beconsidered when designing parts with specific size requirements. With some materials (such as PLA), this is usually unnoticeable, but some filaments may require test printing 6. Fast printing. If print speed is important, you can reduce the thickness of the bottom orthe walls of your print, or choose a larger nozzle diameter7. Modularity. FFF 3D printers are only able to print parts that fit within their build volume,but this doesn’t make them unsuitable for producing large objects. Instead, use amodular design, consisting of multiple components, that can be printed more rapidlyPreparing your 3D model for printingOnce you have a 3D design file, you can transfer it to print preparation software that will turn it into instructions for your 3D printer.Ultimaker Cura is the most widely used 3D printing software in the world, with millions of users, and is free to download from our website.In Ultimaker Cura’s Recommended mode, printing is as easy as loading your model design, choosing key settings (layer height and infill density), and starting your print. You can also switch to Custom mode and tweak multiple settings for highly customized results.With Ultimaker Cura you benefit from the open and integrated Ultimaker ecosystem. Here you will find:• Preconfigured material profiles from leading filament producers, including BASF, Clariant, DSM, DuPont, and Owens Corning• ‘Print from CAD’ integration with free plugins for SolidWorks, Autodesk Inventor, and Siemens NXExtra print profiles and software integration can be downloaded in Ultimaker CuraPrinter operationWhen you have prepared your print in Ultimaker Cura, you can save it to USB orprint via a network.Ultimaker Connect is a network print management tool that enables you to queue multiple print jobs, monitor print progress, and track maintenance and printing analytics from your desktop.This is particularly effective if you have multiple 3D printers. You can create groups of printers for use by different teams, or with a frequently used configuration. Queued print jobs will start automatically when a printer with a matching configuration becomes available.With the Teams feature in Ultimaker Cloud, your 3D printers are accessible to all team members – regardless of where they are, and whether they are on the same network.Post-processingWhen your print finishes, wait for the build plate to cool, then remove the part. If it sticks, use a spatula to free it from the build plate.Often, the only post-processing needed is to remove the thin brim added to your print for optimal adhesion. This can be done by hand or with a small modeling or hobby knife.If you used water-soluble support material such as Ultimaker PVA, you will need to dissolve it before you can use your print. Manually detachable supports, such as Ultimaker Breakaway, can be removed with a pair of pliers.Once supports are removed, you can start additional post-processing options, such as:• Sanding, for a smooth surface finish• Polishing with a plastic polish compound• Gluing modular parts together using a modeling or industrial adhesive• Painting your print, using a primer and separate top coat• Screw threadingNot all post-processing techniques are suitable for all materials, so be sure to research and test your chosen method before trying it on your final part. Follow the manufacturer’s guidelines for any off-the-shelf products you use in post-processing.Removing PVA (left) and Breakaway (right) support materialApplication ideas3D printing gives manufacturers a powerful competitive edge – avoiding outsourcing and speeding up development cycles. With parts fabricated using Ultimaker’s fast and reliable 3D printers, you can ensure faster machine setup, less variation during assembly and fitting, secure part holding, and a smoother production process.But how do you ensure that you are maximizing your return on investment? This list of application ideas will help you make the most of your 3D printer.Jigs and fixturesEnsure efficient production by producing strong and affordable tools, on demand.3D printing is ideal for maintaining a just-in-time inventory and enables you to produce improved iterations within hours.Tip: Create more effective tooling with modular design. Need to prevent a tool from scratching surfaces? Add a layer of semi-flexible TPU 95A material. Does one part of thetool wear down? Design it as a replaceable segment.Quality assuranceTest the quality and accuracy of manufactured parts with precise gauges for the production line. You can also ensure consistency across facilities by sharing 3D models with colleagues. Tip: PLA is a great material for creating precise gauges, due to its dimensional accuracy.Tool organizersEnhance efficiency with 3D printed organizers for production stations. Enable manufacturing best practices such as ‘poka-yoke’ and Six Sigma with customizable workspaces.Tip: Network multiple Ultimaker printers with Ultimaker Connect, and rapidly deliver new organizers to the entire line, so you can evolve and stay lean without delaying production.Replacement partsIf a custom or obsolete part fails and halts production, waiting days or weeks for a new part isn’t an option. With a 3D printer you can quickly replace parts and keep the plant running. Tip: 3D models can also be created from 3D scans, so if a custom part breaks, you don’t even need CAD to create a new one. HP scanning tools integrate with Ultimaker Cura for a simplified scan-to-print workflow.External suppliersUltimaker 3D printers Cost$450 $12Time 35 days 4 daysPrior to in-house 3D printing, Volkswagen Autoeuropa used third-party suppliers to manufacture its custom tools and prototypes. This took several weeks, especially when multiple designs or assemblies were required. It also meant more paperwork and the adoption of a trial-and-error approach, slowing the tool manufacturing process at additional cost.With several Ultimaker 3D printers, Volkswagen Autoeuropa moved 93% of manufactured tool production in-house. Within two years, its assembly-tooling cost savings increased from 70% to 95%. Ultimaker enables Volkswagen Autoeuropa to test solutions without having to contact suppliers, reducing the time taken by an average of eight weeks. The figures below show the cost and time savings from 3D printing the production linetool for the positioning of a vehicle 2.0 TDI emblem.Case study: Volkswagen AutoeuropaBy using 3D printed tools, jigs, and fixtures, Volkswagen Autoeuropa has reduced cycle time operation, labor, and the need for reworking, while improving tool ergonomics. All at a tenth of the cost, saving an estimated $375,000 per year.Luís Páscoa, Pilot Plant Manager at Volkswagen Autoeuropa“The timings and costs to produce tools led us to a fast ROI, better product quality, and satisfaction throughout the entire process – from development stages to the final product. Our innovative 3D printed products are being used in several areas and are consideredbest practices within the Volkswagen Group.”Take the next step to success Build your 3D printing knowledge with industry leaders and experts, or requesta quote, on the Ultimaker website.About UltimakerSince 2011, Ultimaker has built an open and easy-to-use solution of 3D printers, software, and materials that enables professional designers and engineers to innovate every day.

This is to deliver services to customers whether they are in or out of 3GPP network coverage and also to help reduce the load on the 3GPP network.2 EXECUTIVE SUMMARYThis document explains the current state of Wi-Fi networks and the work being carried out in the relevant standards organisations and also other industry bodies who are working towards a variety of solutions and technologies needed to support Wi-Fi Offload. There are sample use cases covering how operators envisage possibly using Wi-Fi Offload in the future.The document also covers the terminal and network requirements and the important issues of security and quality of service needed to make Wi-Fi Offload available to 3GPP network operators.It also makes the following recommendations that the GSMA consider important to the development and deployment of Wi-Fi Offload that can be used by 3GPP network operators. These recommendations cover:•Automatic connection management client•Authentication with 802.1X and EAP-SIM and EAP-AKA•Roaming and Handoff• Security•Quality of Service• Power OptimisationAnd finally the GSMA will liaise as required with the Standards Development Organisations including 3GPP, IEEE, the Wireless Broadband Alliance, and the Wi-Fi Alliance as the main bodies to be considered for any development and standardisation related to 3GPP-Wi-Fi data offloading using protocols defined in the IETF. The GSMA will liaise with these bodies to ensure the development of a suitable Wi-Fi Offload eco-system as required by 3GPP network operators.3 INTRODUCTION3.1 OverviewThis whitepaper outlines the needs of the mobile community in how it would like to utilise Wi-Fi Offload to help promote and develop the usefulness and availability of its services. The paper gives some simple use cases as examples.The whitepaper gives an overview of the current Wi-Fi world; it then provides a high level outline of the expected network and terminal requirements. It considers some of the security and fraud risks before making some recommendations for the 3GPP and Wi-Fi network operators and associated vendor community to consider.3.2 ScopeThe primary objective of this document is to provide a guide to Wi-Fi Offload technology for data services by Mobile Network Operators. It covers deployment scenarios where Wi-Fi Offload is applicable.The focus of the document will be on aspects of the user terminal and infrastructure that are affected by support of Wi-Fi Offload.Out of scope of this whitepaper is the seamless handoff of voice communication (including service continuity across non-interconnected networks) and the business methods for subscribing or unsubscribing to a network;The initial intended audience for this document is the 3GPP and Wi-Fi network operators and associated vendor community.The scope of this work includes scenarios for using Wi-Fi Offload, industry perspective and SDO work, usage scenarios and network and terminal requirements.3.3 Definition of terms3GPP Third Generation Partnership ProjectAAA Authentication,Authorization and AccountingAGW AccessGatewayAES Advanced Encryption StandardANDSF Access Network Discovery and Selection FunctionBSS Basic Service SetCCMP Counter Mode with Cipher Block Chaining MessageAuthentication Code ProtocolCS CircuitSwitchedEAP ExtensibleAuthentication ProtocolEDCA EnhancedDistributed Channel AccessEPC Evolved Packet CoreePDG Evolved Packet Data GatewayEPS Evolved Packet SystemFMC FixedMobileConvergenceGAN GenericAccessNetworkGPRS General Packet Radio ServiceGSM Global System for MobileIEEE Institute of Electrical and Electronics EngineersIETF ICS Internet Engineering Task Force IMS Centralised ServicesIMS IP Multimedia SubsystemI-WLAN InterworkingWirelessLANLAN MAC MAPIM MMS Local Area NetworkMedia Access ControlMulti Access PDN connectivity and IP flow Mobility Multi Media ServicePLMN Public Land Mobile NetworkQoS Quality of ServiceRADIUS Remote Authentication Dial In User ServiceRSN Robust Security NetworkSDO StandardsDevelopmentOrganisations SIM Subscriber Identity ModuleSMS Short Message ServiceSSID Service Set IdentifierUE UserEquipmentUICC Universal Integrated Circuit cardUMA Unlicensed Mobile AccessUMTS Universal Mobile Telecommunications System USIM Universal Subscriber Identity ModuleWBA Wireless Broadband AllianceWi-Fi Wireless network using IEEE 802.11 standards WiMAX Worldwide Interoperability for Microwave Access WISP Wireless Internet Service ProviderWISPr Wireless Internet Service Provider roamingWLAN Wireless Local Area NetworkWPA2 WRIX Wi-Fi Protected Access Version 2 Wireless Roaming Intermediary eXchange4 WHAT IS WI-FI OFFLOADING?It would be advantageous for the mobile operator to be able to offer packet based services to its customers over more networks than just its own 3GPP network. This would potentially mean that in some cases there would be greater overall network capacity available than existing 3GPP networks alone can offer, or service where none currently exists due to the physical constraints of 3GPP networks, such as some in-building areas where external based cell signals cannot penetrate. Thus, any installed Wi-Fi hotspot could potentially be exploited by the 3GPP operator and its customers.Whilst there are other wireless technologies available, this whitepaper is focusing on the use of Wi-Fi as the deployment of public hotspots, and Wi-Fi in homes and enterprises is becoming extremely widespread.One of the important aspects in Wi-Fi Offload is that it must not degrade, rather preferably improve or enhance, the service to the end user, or provide service where it would otherwise not be available. Its use should be functionally invisible to the end user. The service delivery should be seamless and ideally require no end user interaction.Wi-Fi should be complementary to the excellent wide coverage area 3GPP networks already deliver today and LTE networks will deliver in the future.Currently, the level of functionality required by each operator may be different. Functionality may range from manual selection of a Wi-Fi access point for connection to the internet, to fully automatic selection and authentication with operator based network services. Our vision is that seamless (once set up) network selection and authentication will be a common goal. However, different operators will have different core network implementations and differing views on session continuity and service transparency. Such functionality may be achieved in a number of ways, some standardized and some proprietary. As 3GPP operators, there is a strong interest in the deployment of IMS-based core networks as well as a level of network and service transparency. This leads to a strong interest in the implementation of ICS and IP-based messaging (which must interwork with traditional SMS/MMS functionality), impacting both network and device elements though these aspects are beyond the normal sphere of Wi-Fi Offloading and will not be addressed in this paper.5 EXAMPLE USE CASES5.1 Use case using Device accessing video – Mobile TV and/or You TubeA 3GPP network customer has a Smartphone terminal that also has a Wi-Fi capability. They subscribe to mobile TV services as well as regularly watching music videos on You Tube. They are a regular traveller and are often in range of Wi-Fi hotspots in coffee shops, trains and airport terminals as well as hotels.Scenario:•On the bus from the hire car drop-off to the airport terminal the user begins to watch the news from an international news network on the 3GPP network.•As the user enters the airport terminal, his phone detects the presence of a Wi-Fi hotspot.•The device automatically connects and authenticates the user with the hotspot using the USIM/UICC.•Having already checked-in online the user goes straight to security and pockets the phone.•As soon as he is in the departure area, his device is back in his hands and he resumes watching the news programme, however this time the service is being provided via the Wi-Fi Hotspot in the departure area.•He enters a different terminal, where the Wi-Fi coverage is provided by a different Wi-Fi operator, with which a roaming agreement exists.•The device checks that the new provider is allowed, and checks operator policy on use of the roaming network. If there is no charging difference the operation continues on thevisited network. If charging is different due to the change, the user is notified and must approve roaming onto this new network.•The user arrives at his home airport on his delayed flight and catches a taxi home, his local football team is playing tonight and he will miss the match so he selects the TV application from his device’s home screen.•The user selects the football match from the options on his screen, his pre-existing TV subscription is activated.•The user begins to watch the match via the 3GPP network on his device in the taxi.•As the user enters his stone built cottage the coverage from the local 3GPP cell fails but he has a Wi-Fi network in his home.•The device automatically connects and authenticates the user with the residential hotspot using the USIM/UICC.•The user continues to watch the match on his device, and does not miss the first goal being scored by his team. This may be by session re-establishment and not by an uninterrupted handover, this would depend on the implementation deployed.5.2 Use Case using Laptops doing browsing and/or You TubeSimilar to 3GPP roaming, it is desired to be able to transparently connect to various Wi-Fi hotspots provided by different owners whilst being charged accordingly.The laptop is Wi-Fi enabled with 3GPP access provided via integrated hardware or a dongle. Scenario:• A 3GPP subscriber is working on a confidential document on her laptop computer at a local Starbucks café through her secured corporate VPN portal.•After completing her work, she needs to print out the document for her clients.•She heads off to a local Internet Café and rents a computer workstation.•She reaches into her briefcase and looks for her flash drive to transfer the document.•Unfortunately, she remembers that she left her flash drive back at the home office.•After some quick thinking she reaches for her laptop so that she can email the document to her personal email account and then retrieve it from Café’s PC.•She starts the Network Client on her laptop and notices that there is a Wi-Fi hotspot operated by the store.•Instead of connecting to a 3GPP network, the client software automatically authenticates to the Wi-Fi network through pre-loaded credentials, or by using the dongle’s USIM/UICC, and the interoperator roaming agreements.•She emails the document to herself, accesses it on the Cafe’s computer, and prints it out; ready to head to her client’s meeting.5.3 Use Case using multiple SSIDsA network service provider would like to use custom configured access points with multiple SSIDs to offer WLAN connectivity to casual users who are not the owners or normally resident at the premises where the access point is installed. This may support a commercial relationship between the 3GPP operator and the WLAN provider. The casual users’ devices would have to be pre-configured to authenticate to the SSIDs in the access point.Scenario:• A customer has a Wi-Fi capable device which has been pre-configured with the SSID(s) allocated by the 3GPP network provider for use in this service. As part of the commercial offering the customer may also be required to advertise the same SSID’s on their home Wi-Fi Router.•The customer receives a call from a colleague who needs a file to be sent to them urgently. There is no easily accessible and/or obviously Wi-Fi capable establishment(coffee shop, hotel etc) in the near locale and macro 3GPP network coverage is poor.•The customer knows they are a subscriber to this Wi-Fi service and activates the Wi-Fi on their device. Luckily – there is a Wi-Fi Router advertising the pre-configured SSID of the service.•The device authenticates on the Wi-Fi router and he is able to establish a connection and send the file.Figure 1:Network configuration for multiple pre-configured SSID’s6 EXISTING SOLUTIONS6.1 Standard BodiesThere are three main standards bodies involved in Wi-Fi and Wi-Fi Offload. They are the IEEE, 3GPP and IETF.6.1.1 IEEEThe IEEE are responsible for the standardisation of Wi-Fi access and the various improvements and additions that have been carried out. The focus of this paper is the 802.11 and 802.1 suite of standards.6.1.2 IETFThe IETF have standardised many of the protocols used in Wi-Fi including RADIUS, security methods and also mobility mechanisms.6.1.3 3GPP3GPP have defined systems and protocols for interworking 3GPP networks to non-3GPP networks such as Wi-Fi. This includes solutions such as I-WLAN.A summary of the details of the most relevant work of these bodies is included in the annex.6.2 Industry Bodies6.2.1 Wi-Fi AllianceThe Wi-Fi Alliance has published “Best Current Practices for Wireless Internet Service Provider Roaming”1. The document does not specify a standard of any kind, but does rely on the operational application of standards-based protocols and methodologies.WISPr was chartered by the Wi-Fi Alliance to describe the recommended operational practices, technical architecture, and AAA framework needed to enable subscriber roaming among Wi-Fi based WISP’s. This roaming framework allows Wi-Fi compliant devices to roam into Wi-Fi enabled hotspots for public access and services. The user can be authenticated, using RADIUS, and billed (if appropriate) for service by their Home Entity (such as another service provider or corporation).The WFA also certifies devices using Wi-Fi Protected Setup. WPS enables typical users who possess little understanding of traditional Wi-Fi configuration and security settings to automatically configure new wireless networks, add new devices and enable security. This is worth considering as a method to enhance the security of home networks and helping add new devices to the home network.In February 2010 a new Operators Members Interest Meeting was created. This is to offer a voice for operators and to structure their requirements and input to the Wi-Fi community.6.2.2 Wireless Broadband Alliance (WBA)Founded in 2003 by leading telecom operators, the WBA goal is to drive wireless broadband adoption globally by developing common commercial and technical frameworks for interoperability across networks, technologies and devices. Collectively, the WBA members operate around 90,000 Wi-Fi hotspots worldwide with more than 230 million subscribers across Europe & Middle East, Asia Pacific and the Americas.The WBA has implemented commercial Wi-Fi roaming globally using WBA WRIX (Wireless Roaming Intermediary eXchange); The WBA WRIX makes it easier to implement roaming between operators. The WBA collaborates with other industry forums to further enhance WRIX and help harmonize wireless broadband roaming standards.In April 2010, the WBA released WISPr 2.0. WISPr 2.0 is designed for “non” IEEE 802.1X networks as it requires IP communication with the Access Gateway prior to the authentication of the user. WISPr offers authentication services based on layer 3 networking. WISPr 2.0 is designed as a front end to authentication protocols such as Radius, Diameter and the WBA WRIX specification.6.3 Existing Vendor SolutionsThere are several vendors selling Wi-Fi equipment to build networks. Many of these vendors also offer solutions that allow a degree of 3GPP and Wi-Fi internetworking. However often these solutions are proprietary and require additional network elements as well as unique clients1 Best Current Practices for Wireless Internet Service Provider Roaming, Version 1.0, February 2003, Wi-Fi Allianceon the devices. These solutions greatly reduce the opportunity for the user to be able to roam freely and access the services they require where and when they want as they do not offer a standardised solution to allow roaming between networks owned by other operators. Such solutions, or part solutions, are being offered by companies like Attila, Cisco and Ruckus.7 TERMINAL & NETWORK REQUIREMENTS7.1 OverviewIt is important that access points and end user devices support the necessary standard amendments to handle the requirements on data throughput, interference handling, security, authentication and interworking with 3GPP technologies.Apart from that, there exist today innovative technology solutions in the market which can leverage mesh networking principles to solve the backhaul challenge, or smart antenna technologies which can help to deal with interference or to enhance coverage.Today, Wi-Fi Offload is used by some operators to enhance the customer experience with their Smart phones. The current methods include:7.1.1 Automatic provisioningThe mobile device is already provisioned with the SSIDs (and any security keys if required) of the operator’s preferred Wi-Fi providers. On first access to a Wi-Fi provider preferred hotspot, the user may have to enter identification (e.g. the mobile phone number of the device, or PIN number from a text message sent to phone) to verify that he is entitled to the agreed usage tariff (e.g. free use). After the initial access by the device, all future Wi-Fi hotspot access is automatic.7.1.2 Manual provisioningWhere there is no automatic provisioning, the user has to search for and select a Wi-Fi network and enter any security keys required to get access. The facility often exists to store profiles so that every time the device is in range of an existing Wi-Fi hotspot setup, the connection is automatic.7.2 Terminals7.2.1 SmartphonesSmart phones should implement functionality that performs automatic network detection and selection. The device should automatically scan for the appropriate SSID and connect in accordance with operator policy/preference in combination with user defined networks and preferences.The desired functions and features include:•Connection management client, this may be part of the operating system or an additional application.•Downloadable SSID list with operator specified priority and credentials (if not SIM/UICC based). Operator specification of auto authentication parameters, preferred network list, network/SSID blacklist, roaming policies and credentials•Ability for the user to define SSID and credentials for additional networks•Ability to automatically initiate a VPN for specified networks•Respond to Radius request with credentials• Enable 802.1X•Enable EAP-SIM or EAP-AKA•Support of 802.11i/WPA2•Implement power saving features•Support of WPS, including push button configuration•If service continuity is desired, support of the desired scenario highlighted in the annex section A3.5, should be provided along with the appropriate level of Wi-Fi and 3GPP network interconnection. Specifically, the device should include a SIP based IMS client, and possibly support for ICS.7.2.2 Netbooks and DonglesLaptops and netbooks may either have built in 3GPP connectivity or may use dongles to provide connectivity. Nearly all laptops and netbooks are now built including Wi-Fi devices as standard equipment.The desired functions and features include:• Connection management software•Downloadable SSID list with operator specified priority and credentials (if not SIM/UICC based). Operator specification of auto authentication parameters, preferred network list, network/SSID blacklist, roaming policies and credentials•Ability for user to define SSID and credentials for additional networks•Ability to automatically initiate a VPN for specified networks•Automatically scan for SSID and connect in accordance with operator policy/preference in combination with user defined networks and preferences•Respond to Radius request with credentials• Enable 802.1X•Enable EAP-SIM or EAP-AKA, if there is built in 3GPP connectivity or using a 3GPP dongle•Support of 802.11i/WPA2•Implement power saving features•Support of WPS, including push button configuration•If service continuity is desired, support of the desired scenario highlighted in the annex section A3.5, should be provided along with the appropriate level of Wi-Fi and 3GPPnetwork interconnection. Specifically, the device should include a SIP based IMS client, and possibly support for ICS.7.3 Network Requirements:The following is a list of the expected requirements for the networks to support Wi-Fi Offload.•Support of 802.1X•Support of 802.11i/WPA2•EAP-SIM or EAP-AKA enabled•Home access points should support WPS, including push button configuration•Interconnection with 3GPP network operator via I-WLAN or via Internet•Automatic and seamless handoff may become a requirement. Out of scope for this paper.•Collection of billing data and ability to properly format and communicate to the mobile operator.•If service continuity is desired, support of the desired scenario highlighted in section11.3.5 (annex) should be provided along with the appropriate level of Wi-Fi and 3GPPnetwork interconnection.•If session continuity is required then the network must implement such capability based on 3GPP or proprietary solutions.•As standards evolve, support for IP Flow Mobility, Local IP Access and Selected Internet IP Traffic Offload should be considered.7.4 Network Selection:Network selection should provide the following capabilities:•For the device to select the network based on the capability of the network such as QoS, connectivity, signal strength etc.•For the device to detect and switch to the preferred network (when not in an active communication state with the current network).•The Home Operator to be able to configure the list of the preferred Wi-Fi access networks that can be used for automatic selection.•The user to be able to configure the list of the preferred Wi-Fi access networks that can be used for automatic selection.•The user to be able to select manually from the available Wi-Fi accesses available. Network selection mechanisms have been specified by 3GPP and these include network selection for I-WLAN and ANDSF. For operators which have both WiFi and 3GPP infrastructures, it is possible to use ANDSF. This is a layer 3 protocol specified by 3GPP. Itenables mobile devices located in areas of two or more different types of access connectivity to select the most appropriate access network by exchanging information between the mobile device and a server. This is covered in more detail in the Annex A3.1.1. There is a need for further investigation of the ANDSF functions and whether they meet the requirements for network selectionNetwork selection requirements for I-WLAN is specified by 3GPP in specification TS22.2348 QUALITY OF SERVICEMultimedia applications such as VoIP, VoD and Internet Radio have different traffic characteristics and quality of service QoS requirements as compared to traditional internet data traffic. For example VoD requires high bandwidth while VoIP is bursty in nature and requires low delay and jitter. As a result, to ensure a high level of user experience, these traffic types need to be treated differently from the traditional internet traffic. Further, the available bandwidth in the Wi-Fi based WLAN is also limited. Thus it is very essential to manage the access to the Wi-Fi based WLAN resources and prioritise the traffic to ensure appropriate QoS to different kinds of traffic.The IEEE 802.11e standard addresses the link level (between a station and an access point) QoS on Wi-Fi thorough enhancement to the MAC (Media Access Control) layer protocol. The standard provides two approaches - Prioritisation of Traffic and Parameterisation of Traffic. In the traffic prioritization approach, the traffic is classified into one of the four categories - Voice, Video, Best Effort and Background. The transmission is done using Enhanced Distributed Channel Access (EDCA) mechanism.As the QoS capabilities of the 802.11e standard provide QoS on a per-link basis, it can extend existing end-to-end QoS frameworks across Wi-Fi access to end terminals. In general, there are two approaches for providing end-to-end QoS - one using differentiated services and the other based on resource reservation.9 SECURITY AND FRAUDTwo sets of security requirements need to be addressed:•Wi-Fi network access security: This concerns authentication of the customer towards the Wi-Fi network, of the network towards the customer device, and the protection of the Wi-Fi access link.•Services access security: This concerns authentication of the customer towards operator or third party services when connected via Wi-Fi (or other non-cellular access networks), and the protection of this link.In order to provide basic offload of Internet access, Wi-Fi network access security is needed to protect against theft of service and other attacks. However, for the offload operator or third party provided services that are normally secured based on 3GPP network techniques (e.g. music portal, application store, etc.), additional service access security is needed.9.1 Wi-Fi network access security9.1.1 802.11i。

化学文献查询方法

化学文献查询方法一、检索方法：学化学的人，如果刚进实验室的话，往往是两眼黑，不知道如何下手，要下手往往是漫天刷浆，抓不住重点！那么如何能抓住重点，进行有目的的去读一些论文呢？首先用google来看看你的研究方向，比如你研究某系列的天然物合成，那么你就用这个名字去search，然后先看看有没有中文的介绍，如果有的话，那么先看看它是不是review，最好的是找到中文的review，然后大体看以下，了解你要做的东西当前的进展，有什么人在做，结果如何啊。

然后按图索骥，找到英文的文献，那么可能有很多英文的文献，如何去选呢？选择发表在影响因子高的期刊上的文章来读！！！这个很重要！，因为大牛的教授都是把自己的好结果发在高水平的论文上的。

只要你找一篇比如是JOC上的文章，那么就要看好，里面是否引用了某些review，如果有的话，那么你就去找那个review，一般来说国外的高水平的review都是约稿的，请的是当前的牛教授来写的，有读的价值！依次你可以进行全面的了解相关的研究进展了。

如何对待中文的杂志呢？我的意见可能偏激，我认为完全没有任何读的价值！为什么呢？第一，20%的杂志覆盖了80%的内容，第二，IF太低，低于1的就是垃圾了，没有引起任何人的重视，那么这个结果是没有价值的。

第三，很多中文文献的重复性很差，数据被人为的修改。

那么对待英文呢？同样，低水平的也是很多，对于IF低于1的不要去看，就是看了也不要太当真，原因同中文文献一样，对于化学来说也就是不超过20个有意义的杂志吧，美国化学社的全部，德国的wiley上有几个很好的，sciencedirect上的几个影响因子在2以上的，英国化学社的全部，也就是这些了外加thieme的一个。

完整的检索分为两部分：①寻找相关的文献出处；②找到收录文献的数据库，或者使用相关软件，进行全文下载阅读。

第①步是重要的，第②步是次要的。

可以利用的三大检索工具：Beilstein的CrossFire；ISI的Web of Science；CA on CD。

Need help? (8)IntroductionThis document describes the PPM Cache architecture up to PPM 9.30, as well as the changes introduced to the Cache in PPM 9.31. It should help PPM Administrators to correctly tune PPM Caches in order to achieve optimal system performance.PPM Cache OverviewThere are two caches in PPM that can be tuned by PPM Administrators:-Legacy cache (Table Components, Request Type Search Fields, List Validation Values, etc.).It is configured in <PPM_HOME>/conf/tune.conf. Setting the parameters in server.conf works too and some of the parameters can be edited from the admin console.You can view its cache statistics in the “Server Cache Status” report in Workbench’s AdminTools.-New cache (Requests, Request Types, Modules, Portlets, Workflows, etc.).It is configured in <PPM_HOME>/conf/cache.conf.You can view cache statistics in the “CacheManager Statistics” report in Workbench’s AdminTools.Comparison between Legacy Cache and New CacheThe new cache has the following advantages over the legacy cache:-All cache objects are stored using java SoftReference. As a result, if the JVM runs out of Heap Memory, objects in the cache will be automatically garbage collected to free up memory. Thismakes it possible to store large amounts of data in the cache without risking out-of-memoryissues under heavy system load.-There are more cache configuration parameters (at least until PPM 9.31, in which new cache configuration has been simplified).-It is possible to invalidate a single object in the new cache by using ksc_flush_cache special command (which only works with new cache), whereas only full cache flush is possible whenusing kRunCacheManager.sh (which works with both legacy and new cache).-The new cache provides configurable staleness checks, whereas such checks are hard coded in the legacy cache.-More statistics in the Cache report (number of staleness checks, average load time, number of flushes of the different type).Understanding the PPM Cache Statistics reportsThe following information is available in the cache server reports.Legacy CacheFollowing information is available for each legacy cache in the “Server Cache Status Report”:∙Maximum number of objects that can be cached (Cache size)∙Number of additional objects that can be cached (Free units)∙Number of hits, misses and swaps (swaps meaning replace an object by another one when max size is reached)∙Miss rate (the lower, the better)∙Estimation of the amount of memory taken up by the cacheNew CacheFollowing information is available for each new cache in the “CacheManager Statistics Report”:∙Hits, misses, and hit rate (the higher the hit rate, the better)∙Number of cache flushes (broken down by the categories "old", "idle", "soft reference reclaimed", and "max cache size reached")∙Average load time to load an object from database when it is not in the cache∙Number of staleness checks performed∙Max cacheable objects (Cache size), cached object count and maximum idle time∙Whether the cache is distributed or not (if it is, removing an object from the cache in any node of the PPM cluster will send a message to all other cluster nodes to remove that object fromtheir cache).PPM Cache TuningTuning PPM Cache performance should be done at the same time as tuning PPM JVM Heap size. This means finding the right balance between 2 things:-JVM Heap size: Before PPM 9.20, only 32bits JVM was supported, which limited the JVM Heap size to ~1.3GB. Since PPM 9.20 and the adoption of 64bits JVM, the size of the JVM Heapmemory is only limited by the installed physical memory. However, too large Heap size canresult in long full garbage collection times, during which the application is unresponsive. It iscommon to see PPM JVM heap sizes of up to 4 GB, and sometimes more on Service nodes.-Caches size: A larger cache size means more cacheable objects, a better hit rate, and fewer objects to reload from the database, which result in better application performance. However, if cached objects end up taking too much memory, this will impact the performance of theapplication and might even cause out-of-memory problems. Note that only legacy cache isprone to causing such memory problems, as the JVM will automatically discard objects from the new cache whenever the available free memory runs too low.To summarize:-If JVM Heap size is too large, full garbage collection periods will be too long and application might become unresponsive for seconds, degrading users experience-If Caches are too large and end up using up too much memory, the performance of the application will degrade and in the case of legacy cache it might even cause out-of-memoryissues.Tuning your PPM cache can be done by following these steps, which may end up conflicting with each other; if that happens, use your best judgment.-If you see a high number of swaps (legacy cache) or “max cache size reached” flushes (new cache), increase the cache size.-If you see some “soft reference reclaimed” flushes (new cache), increase the JVM Heap or reduce the cache size for cache using up large amounts of space.-If you see a high miss rate (above 20%, legacy cache) or a low hit rate (below 80%, new cache) even after prolonged PPM usage (at least one day of heavy usage), increase the cache size.-If you notice long full garbage collection times (many seconds) during which the system is unresponsive, reduce the Heap size or better tune the JVM Garbage collection. Note that youwill need to use a JVM monitoring tools in order to ensure that JVM pause times are caused by full garbage collection.There are some additional tips that might help you when tuning the PPM cache:1)There is no “standard” cache configuration. Measure, tune, rince & repeat until you reachsatisfactory numbers. All PPM usages are different, and as a result caches configurations should be tuned accordingly.2)When tuning the PPM cache, try to do so after capturing statistics during the highest peak loadtime (usually happening on Friday afternoon or Monday morning). Tuning your cache onlymakes sense if it is tuned to properly handle peak load usage.3)Try not to flush the caches (using kRunCacheManager or ksc_flush_cache) in an automated wayunless you really have to. If using kRunCacheManager, NEVER use the “A” option to flush allcaches in an automated script; you should not flush more caches than necessary.4)If memory limit doesn’t allow you to set the proper max cache size for all the entities, you canrank the cache t o optimize first by the value “Average Load time” x “Misses”, and first increase the cache size of the cache(s) with the highest value. They are the most likely to have ameasurable performance impact.5)You might want to tune differently the PPM nodes in your cluster depending on whether theyare Service nodes or Web User only nodes. The entities loaded (and thus the optimal cachesettings) are different. For example, a pure Service node will never load portlets or menus, but might need a larger cache size for fiscal periods.6)Don’t forget that when using kRunCacheManager.sh, it will always flush selected caches on allnodes of your PPM cluster, but it will reset caches statistics and force garbage collection only on the node it is connected to.Flushing the PPM cache with kRunCacheManager.sh and ksc_flush_cache There are two ways to flush a PPM Cache in a manual or automated way: kRunCacheManager.sh (command line tool), or ksc_flush_cache (special command). They should be called after modifying the data directly in the database without going through one of the supported PPM interfaces (Web UI, SOAP Web Service, REST Web Service, etc.).kRunCacheManager.shkRunCacheManager.sh is a shell script that is run from the command line.Syntaxsh ./kRunCacheManager.sh [<URL>] <cache number>-“URL” parameter is optional. If omitted, it will connect to the first running RMI_URL defined in server.conf. You can pass multiple RMI urls, separated with semicolons (‘;’), and it will connect to the first running one. It is safe to omit this parameter unless you want to connect to a specific PPM node, for example to reset cache statistics or request a garbage collection.-“Cache Number” parameter is the number next to the cache that you want to flush. In order to view the list of caches with their number, run the command without any parameter to list all caches and be prompted for possible options. You can also input a letter to trigger thefollowing actions:o A: Flush All Caches. It is strongly advised not to use this option when runningkRunCacheManager in an automated way.o B: Flush Validation Caches. This will only flush the validation related caches. It can be used when validation definition or values are directly edited in PPM Database.o C: Reset Cache Statistics Counters. This only affects the node you are connected to.o D: Force Garbage Collection.Issues & Limitations-The order of the caches in the list is not consistently enforced and can vary between environments or PPM versions. As a result, if you do flush a specific cache designated by itsnumber in a script, it’s possible that the corresponding cache may change at some point in the future. You should verify that the cache numbers haven’t changed after every PPM upgrade or environment change.-It is not possible to only flush one entity in a cache; the whole cache has to be flushed. This can result in performance impact as all objects from the flushed cached will need to be reloaded.This could have performance impact under heavy load if some caches are flushed too often.-It is strongly advised NOT to use the “flush all caches” option (“kRunCacheManager.sh A”) in an automated way, as it may have performance impact under heavy system load.-If the cache is flushed using kRunCacheManager.sh while the cache maintenance thread is running (it runs every 10 seconds by default), an exception may be fired and thekRunCacheManager.sh cache flush action may be ignored.ksc_flush_cacheksc_flush_cache is a PPM Special Command that can be invoked from any command step (workflow step, PPM report command step, etc.).It only works with new caches.Syntaxksc_flush_cache <cache-name> [<id>]-“cache-name” parameter is the name of the new cache, as defined in cache.conf. For example, in the following cache.conf line:cache.datasource.title = Dashboard Datasourcesthe cache name is datasource.-“id” parameter is optional. If omitted, the cache is flushed from all its entities. If specified, only that entity will be removed from the cache.Issues & Limitations-ksc_flush_cache only works with new caches .-As of PPM 9.30, ksc_flush_cache is an undocumented (though officially supported) special command.-As of PPM 9.30, passing an entity ID to ksc_flush_cache will only work when the cache key is an Integer value. If it is a String value, it will not be flushed, and the only option to remove thedesignated entity will be to flush the whole cache.PPM Cache changes in PPM 9.31Following changes have been done to PPM Cache in 9.31 in order to correct existing issues and limitations.Conversion from legacy cache to new cacheAll the legacy caches listed in kRunCacheManager.sh but one (Scoring Criteria) have been converted to new cache.All these caches are now configured from cache.conf, and their parameters in tune.conf (orserver.conf/admin console) have been deprecated and are not used anymore.Simplification of new cache configurationSome parameters in cache.conf have been removed in an attempt to simplify cache configuration.-The only parameter that can be tuned for all caches is the cache size (parameter “maxSize”).-Parameters “maxAge”, “maxIdleTime”, “resolver” and “stalenessCheckGraceInterval” have been removed.-Parameter “distributed” is inferred automatically based on whether a staleness check in defined (distributed = false) or not (distributed = true).-Cache is automatically set to disabled if maxSize = 0.A staleness check has also been added for request types and table components; even though it’s not enabled by default, if one relies on direct DB upd ates to modify request types or table components, it’s preferable to enable the staleness check rather than disable the cache. Staleness check will only work if column LAST_UPDATE_DATE is modified during data update.One side effect of cache simplification is that the cache maintenance thread (previously used to enforce maxAge and maxIdleTime of cached objects) is now only used to reload the cache.conf configuration when modified at runtime. It doesn’t cause issues anymore when running at the same time as kRunCacheManager.sh.Changes to CacheManager Statistics report-Flush counts of types “old” and “idle” have been removed.-“Cache Flush All” count has been added. It displays the number of times the whole cache has been flushed. It helps identifying abuses of “kRunCacheManager.sh A” or of unnecessary fullcaches flushes.Running “kRunCacheManager.sh A” will increment this value by 1 for all caches.Changes to kRunCacheManager.sh-The order of listed caches has changed: it still lists legacy cache followed by new caches, but now the new caches are ordered alphabetically by cache name.-When listing all caches, the cache name of new caches is displayed in parenthesis after the cache title.-When flushing new caches, you can now use the cache name in place of the cache number. It is advised to always use the cache name, as it doesn’t rely on any ordering of caches in that list.-An extra optional parameter has been added to the command, to pass the entity ID to flush. So you can now flush one specific entity from a cache using kRunCacheManager.sh using thefollowing syntax:sh ./kRunCacheManager.sh [<URL>] <cache name (or cache number)> [<entity ID>] - A new action (E) has been added, that lists all keys in each of the new caches along with their type (String or Integer). This can help diagnose whether a specific entity is currently stored inthe cache or not. Note that in MLU environments, the same key can be displayed multiple times if it is stored in the cache using different languages.Changes to ksc_flush_cache-Passing an entity ID to ksc_flush_cache will now work regardless of the key type (String or Integer).-You can now flush the legacy caches by passing their cache number (as inkRunCacheManager.sh) instead of the cache name. Since there is only one legacy cache left in9.31, it means passing “1” as the cache name to flush the “Scoring Criteria” cache.More questions?

包括从中小企业到大型公司、学校单位或政府机关，甚至是银行与证券公司等，都是通过Internet来与合作伙伴进行沟通、数据共享以及电子交易等服务。

而在计算机网络化日趋重要的今天，Internet提供了一个让通讯标准化的环境，彻底改变了人与人、人与计算机以及计算机与计算机之间的沟通模式，并大幅提高了工作效率与准确性。

但综观当前Internet的发展现状，仍是属于起步的阶段，因此有许多的问题急待解决。

而每当一个重要的问题找出解决之道后，Internet的功效会进一步提高，用途也变的更加广泛。

但是，也由于我们对Internet的依赖越来越加深，因而衍生出许多棘手的问题，例如网络阻塞、带宽使用不当、网络断线或带宽不足以及各种类型服务器扩充性的问题。

整体来说，广域网络（WAN ）的连接质量成本效益最佳化、链路带宽使用最有效率与链路的稳定性，是采用广域网络为基础的计算机环境成功的关键因素。

针对于此，AscenVision公司提出了具有针对性的解决方案，利用AscenVision公司的广域网带宽管理设备AscenLink®，可以有效的解决上述问题。

2 AscenLink®产品介绍AscenLink® 是亚盛信息技术所推出的广域网络（WAN ）/ 局域网络（LAN ）边界设备之一，可整合不同ISP及网络WAN线路，使进出Internet/Intranet 的流量提供承载分配及容错备份，确保Internet/Intranet的存取服务不会中断，维持线路的平稳、快速的传输品质。

AscenLink® 能与现有的硬件设备与应用系统相兼容，不需要复杂的设置，并内建带宽管理功能，让有限的带宽资源达到最佳的使用效能。

AscenLink®主要根据客户在对广域网络所遇到的问题、及MIS对于网络管理的无力感，提供一个超值及完善的解決方案。

一、面对用户拥有多条广域网链路，却无法有效的充分利用和有效管理时，AscenLink®提供了多线路整合的功能。

二、针对用户的多链路，AscenLink®提供了多链路双向的负载均衡功能，使得用户的多条链路实现负载均衡和冗余备份。

三、为了确保关键业务的应用，AscenLink®内置了QoS 功能，能够根据实际商务需求、服务种类、封包类型、流量来源以及目地（以IP 与网络子网来定义）等参数决定带宽分配的政策。

通过滤除非预期的网络流量，能大幅改善带宽的使用率，使您在接收重要资料时能拥有最好的传输品质。

四、强大的报表系统功能是AscenLink®有别于同类产品的一大特点，通过LinkReport TM详细的报表，可以使的用户实时的了解在每一条广域网链路上服务种类、封包类型、流量来源以及目地，同时也能实时了解每一条广域网链路的连接状态。

2.1 AscenLink® 主要特色与优点负载均衡（Load Balancing）AscenLink® 能够确保用户租用服务供应商多条线路时，其效能达到最佳化。

达到线路最佳化的目的，是确保信息在不同的线路上传输时，能够选择最快速、最稳定的线路传输。

这必须依用户不同的环境及需求选择不同的演算法则（Algorithm ）。

AscenLink® 可支援下列六种负载均衡之演算法：固定指派（Fixed ）：选择固定的广域网络连线，参数是广域网络连线的号码。

根据连接数（By Connection）：比较各线路上建立的连接数量，让数据流依照所输入的连接比例方式在指定的广域网络连接上分配流量。

轮流指派（Round-Robin ）：按照单纯的比重分配，参数是分配到各广域网络连线的比重。

根据下载流量（By Downstream Traffic ）：选择下载负载最轻的广域网路连线，参数是需要考虑的广域网络连线。

根据上传流量（By Upstream Traffic ）：选择上传负载最轻的广域网络连线，参数是需要考虑的广域网络连线。

根据全部流量（By Total Traffic）：选择总负载（上传及下载）最轻的广域网络连线，参数是需要考虑的广域网络连线。

外连线路状态侦测（WAN Link Health Detection ）及高容错力AscenLink® 采用精心设计的检测机制，自动侦测对外连线状态，通过智能型路由引擎为流量做最适当的路径安排。

当任一条对外连线中断或不稳定时，AscenLink® 会自动将流量导引至其他可用且稳定的外连线路，以确保整体对外连线永不中断。

一旦发生问题的连线回复正常时，AscenLink® 也能自动侦测出来，并重新分配每条连线的流量负载，将整体对外连线的使用率做最有效率及最佳化的运用。

多条外连线路整合（WAN Line Trunking ）AscenLink® 能够整合多条对外网络连线，包括DDN、FR、ISDN到ADSL、Cable等宽带网络，让局域网络内的使用者连线至广域网络时，如同使用一条虚拟外连线路（WAN Line Trunking ），既快速又可靠。

AscenLink® 针对不同需求可提供3至8个对外连接端口的机型供企业选择使用，同时也可支援虚拟联结（Virtual Link），通过与外部交换器的连结，最多可连多达40 条广域网络线路，达到最佳对外连线扩充的功能。

除自动流量导引外，AscenLink® 也支持特殊流量导引政策。

网管人员可依下列方式做特殊专线流量导引，让您的商业应用政策与网络政策能够紧密地结合。

1. 源地址（Source IP ）2. 目的地址（Destination ）3. 应用种类Link TunnelLink Tunnel是AscenLink® 提供的一个强有力的功能，它不仅仅是能够完成普通意义上的负载均衡和冗余备份，而且保证了在一个Connection中实现数据传送的不间断性。

许多的关键业务，如VPN、Video Conference、电子商务等在广域网络上的应用，都面临着一个问题，那就是如何有效的保证数据的传送能够在一个连接中（Connection）完成，Link Tunnel实现了这个功能，保证了关键业务的执行。

提供备份线路功能AscenLink® 提供Backup Line功能，可以使您的备用链路出于StandBy状态，当主用链路的流量达到某一个设定值时，备用链路将自动启用，进行有效的流量负载分担。

如果主用线路因为以外发生中断，备用线路（Backup Line）将及时承担起传输作用，避免网络瘫痪，极大的降低了因此带来的损失。

持续路由（Persistent Route）当用户需要连接到公网上需要身份认证的服务器时，如做电子商务或邮件认证时，可以通过持续路由完成认证的过程，然后再按照制定的智能路由进行有效的负载均衡。

Multihoming 机制Multihoming ，意指在Internet与企业网站间架设多条连线，包括单一ISP 或不同ISP 的线路，以确保两者之间连线的稳定与品质，并大大降低断线风险.负载均衡＆不间断服务通过MultiHoming机制，AscenLink可以保证用户访问内部服务的不间断及在多条链路上进行负载均衡，保证某条链路断路后对内部数据的访问的不间断，南北电信互访速度问题针对南北电信网络互访速度较慢的问题，AscenLink可以通过相关策略设定（Local DNS设定），回应解析请求用户相同ISP的A记录地址，从而保证用户通过相同ISP链路进行服务的访问，加快了内部数据的访问速度。

此功能特别针对您有对外服务的应用，而且要保证服务不中断，诸如：●企业网站●政府对外服务系统●网络下单系统●远程教育系统●银行、金融电子交易Server Load Balance（服务器负载均衡）AscenLink不仅提供对WAN链路的负载均衡及不间断服务，同时可以提供对内部服务器进行负载均衡的功能。

通过AscenLink WAN口的PublicIP与内部服务器进行相关的映射，可以保证外部用户对这些提供相同内容服务器访问的负载均衡，可以将访问请求依次轮循到内部的不同服务器，从而减轻每台服务器的负载量，加速访问速度。

独创的SwiftDNS TM专利技术DNS传统容错（DNS轮询）的一个问题是一旦某个服务器出现故障，即使及时修改了DNS设置，还是要等待足够的时间（刷新时间）才能发挥作用，在此期间保存了故障的服务器地址的客户计算机将不能正常存取服务器。
