更多的是系统细分成了独立的控制孤岛。

没有一个统一的网络标准使得用户对驱动器和用户接口的需求越来越多。

从传感器到主控制器,数据的传输必须经过不同的CPU和驱动软件,其结果是传输速度低,缺乏透明度,软件和维护费用高。

在所有的网络技术中,以太网技术是至今最理想的选择,TCP/IP以太网已经成为事实上的标准网络,将标准TCP/IP以太网延伸到工业实时控制并和通用工业协议(CIP)的结合,将很好地帮助用户获得更加开放集成的工业自动化和信息化的整体解决方案。

EtherNet/IP就是为实现这一目的的标准工业以太网技术。

KVM

KVM的定义多电脑切换器（KVM）是网络中的治理设备，它是Keyboard（键盘）、Video （显示器）和Mouse（鼠标）三个单词的第一个字母。

即能够实现用一套键盘、显示器、鼠标来控制多台设备。

正式的名称为多计算机切换器。

简单的说，就是一组键盘、显示器和鼠标，控制2台、4 台、8台、16台甚至到4096台以上的计算机主机。

类型主要指KVM切换器所控制的终端类型，如果终端主要是控制电脑则可以叫做多电脑控制类型。

KVM的领域，也已经扩展到串口设备，如集线器、路由器、储存设备及UPS等。

精密的KVM解决方案可以让多位使用者在任何地点、任何时间访问数以千计的服务器和网络设备。

而且，如事件纪录、远程电源管理、多层次使用者权限安全管理、环境警示系统、Cat5电缆线等功能，帮助IT管理者从他们希望的任何地点安全地管理日常的运作。

让您轻易访问、监视及管理您所有的IT设备。

称之为全方位数据中心管理（Total Data Center Management，TDCM）。

它是一种集中式管理，可以增加IT设备正常运作的时间（因为可以减少访问及诊断的时间），节省可观的楼地板面积以及不必要的设备与人力，毋须考虑网络的效率就可以访问所有的设备，可以终极地提升您的商业竞争力。

在企业中，网络治理员随着极其繁重的治理、维护工作，因此如何从这些繁杂的工作中解脱出来，成了广大网管人员最关心的事。

而在网络中布置KVM设备，则可以帮助网管人员提高工作效率，使网络的治理、维护变的轻松起来。

KVM种类多电脑切换器（KVM）分类：按网络环境分：基于IP和非IP的（远程控制和一般应用）按设备环境分：机械和电子的（手动和自动）按安装方式分：台式和机架式KVM按照不同的标准，可以有不同分类。

例如按工作模式，可以分为模拟式KV M和数字式KVM；按应用的范围，可以分为高中低三类；按网络环境，可分为基于I P和非IP的。

1.模拟式与数字式模拟式KVM主要是早期的一些产品，应用于距离不远的机房或者本地单一机柜，价格也比较低，对中小企业来说具较高的性价比。

Warriors_Of_The_Net(网络战士)配音文字

Warriors_Of_The_NetFor the first time in history people and machinery are working together, realizing a dream. A uniting force that knows no geographical boundaries. Without regard to race, creed or color. A new era where communication truly brings people together.This is the Dawn of The Net.Want to know how it works? Click here to begin your journey into the Net.Now exactly what happened when you clicked on that link? You started a flow of information. This information travels down to your own personal mail-room where Mr. IP packages it, labels it and sends it on its way. Each packet is limited in its size. The mail-room must decide how to divide the information and how to package it.The IP packet now needs a label, containing important information such as senders address, receivers address and the type of packet it is. Because this particular packet is going out onto the Internet, it also gets an address for the Proxy Server which has a special function as we¡¯ll see later.The packet is now launched onto your Local Area Network or LAN. This network is used to connect all the local computers, routers, printers etc. for information exchange within the physical walls of the building. The LAN is a pretty uncontrolled place and unfortunately accidents can happen.The highway of the LAN is packed with all types of information. There are IP packets, Novell packets, Apple Talk packets - Uh, they¡¯re going against traffic as usual. The local router reads the address and if necessary lifts the packet onto another network.Ah the router. A symbol of control in a seemingly disorganized world. There he is..systematic, uncaring, methodical, conservative and sometimes not quite up to speed. But he is exact¡- for the most part. As the packets leave the router, they make their way into the corporate intranet and head for the router switch. A bit more efficient than the router, the router switch plays fast and loose with IP packets deftly routing them along their way. A digital pin-ball wizard if you will. As packets arrive at their destination they are picked up by the network interface, ready to be sent to the next level. In this case, the proxy. The proxy is used by many companies as a sort of ¡°middleman¡± in order to lessen the load on their Internet connection. And for security reasons as well. We can see that the packet are all of various sizes, depending on their content.The proxy opens the packet and looks for the WEB address or URL. Depending upon whether the address is acceptable¡-the packet is sent on to the Internet. There are, however, some addresses which do not meet with the approval of the proxy (that is to say corporate or managementguidelines). These are summarily dealt with. We¡¯ll have none of that. For those who make it, it¡¯s on the road again.Next up - the Fire Wall. The corporate Fire Wall serves two purposes. It prevents some rather nasty things from the Internet from coming into the intranet. And it also can prevent sensitive corporate information from being sent out to the Internet.Once through the fire wall, a router picks up the packet and places it on to a much narrower road or band-width, as we say. Obviously, the road is not broad enough to take them all.Now you might wonder what happens to all those packets which don¡¯t make it along the way. Well, when Mr. IP doesn¡¯t receive an acknowledgment that a packet has been received in due time, he simply sends a replacement packet.We are now ready to enter the world of the Internet. A spider web of inter-connected networks which spans our entire globe. Here, routers and switches establish links between networks.Now, the Net is an entirely different environment than you¡¯ll find within the protected walls of your LAN. Out here, it¡¯s the Wild West. Plenty of space, plenty of opportunities, plenty of things to explore and places to go. Thanks to very little control and regulation new ideas find fertile soil to push the envelope of their possibilities. But because of this freedom, certain dangers also lurk. You¡¯ll never know when you¡¯ll meet the dreaded Ping Of Death. A special version of a normal request Ping which some idiot thought up to mess up unsuspecting hosts.The paths our packets take maybe via satellite, telephone lines, wireless or even trans-oceanic cable. They don¡¯t always take the fastest or shortest routes possible, but they probably will get there - eventually. Maybe that¡¯s why it¡¯s sometimes known as the World Wide Wait. But when everything is working smoothly, you can circumvent the globe 5 times over, at the drop of a hat - literally. And all for the cost of a local call or less.Near the end of our destination, we¡¯ll find another Fire Wall. Depending upon your perspective as a data packet, the fire wall can be a bastion of security or a dreaded adversary. It all depends on which side your on and what your intentions are.The Fire Wall is designed to let in only those packets that meet its criteria. This wall is operating on ports 80 and 25. All attempts to enter through other ports are closed for business.Port 25 is used for mail packets, while port 80 is the entrance for packets from the Internet to the Web server.Inside the fire wall, packets are screened more thoroughly, some packets make easily through ¡°customs¡± while others look just a bit dubious. The Fire Wall officer is not easily fooled, such as when this ping ofdeath packet tried to disguise itself as a ¡°normal¡± ping packet. For those packets lucky enough to make this far, the journey is almost over. It¡¯s just to line up on the interface to be taken up into the web server.Nowadays, a web server can run on many things. From a mainframe, to a web-cam to the computer on your desk. Or why not your refrigerator? With the proper set-up, you can find out if you the makings for Chicken Catchitory or if you have to go shopping.Remember this is the Dawn of the Net - almost anything¡¯s possible. One by one, the packets are received, opened and unpacked. The information they contained, that is your request for information is sent onto the Web server application. The packet itself is recycled. Ready to be used again. And filled with your requested information. Addressed and sent out on its way back to you.Back past the fire walls, routers, and on through the Internet. Back through your corporate fire wall and onto your interface.Ready to supply your web browser with the information you requested. That is - this film.Pleased with their efforts and trusting in a better world, our trusty data packets ride off blissfully into the sunset of another day, knowing fully they have served their masters well.Now isn¡¯t that a happy ending?。

The net-shape forming of gears净成型齿轮外文翻译(含译文)

Ž.Materials and Design212000271᎐278The net-shape forming of gearsT.A.Dean UIRC in Materials for High Performance Applications and School of Manufacturing&Mechanical Engineering,The Uni¨ersity ofBirmingham,Birmingham B152TT,UKAbstractOver recent years vigorous developments have been undertaken to enable the production of gears and gear forms by forming methods.The driving force behind this activity has been,in common with other areas of component manufacture,greater added value.These developments are leading to the commercial feasibility of producing gear tooth forms of high quality,ready for use. For applications where extreme high quality of tooth form is not necessary,such as automotive differentials,forged gear forms can be employed without further machining.Because the dimensional quality required of the running teeth of gears in automotive gear boxes is high as yet only machined tooth forms are sufﬁciently accurate.This paper describes the background to the research on the forging of spur and helical gear forms with particular attention on the production of high quality gears for land transport applications.ᮊ2000Elsevier Science Ltd.All rights reserved.Keywords:Forging;Net-shape forming;Gears1.IntroductionForming gears rather than cutting them has the obvious advantage of greater utilisation of raw material and high productivity.The process of forming thus has greater potential for large quantity batch production, such as required by automotive companies and con-sumer goods industries.In spite of these positive as-pects the economics of fully formed spur and helical gears for power transmission have not yet been proven to be acceptable and cannot be until a robust process-ing route is established.Some evidence exists to show that formed gears have higher dynamic properties than do conventionally cut ones which would enable them to be uprated.This is attractive when weight is a penalty. Cold forming is used to produce parts with the highest accuracies.It is possible to produce bevel gears by cold forging.The forging of bevel gears started in Germany in the1950s where lack of gear cutting equipment stimulated the development of a hot forging process to produce gears withﬁnish formed teeth.The main char-U Tel.:q44-121-414-4176;fax:q44-121-414-3958.acteristic of the process was the high degree of process control including the use of the then fairly new electro-discharge machining process for making the dies.Depending on overall geometry,spur and helical gears can be extruded cold.The types of geometry of gears used in power transmission gear boxes precludes extrusion and the most feasible method of manufacture is forging in completely-closed die cavities.Because of their high diameter-to-thickness ratios,to enable die to beﬁlled using acceptable pressures,workpieces must be heated which prevents the production of net-shape gear teeth of high quality.Much current activity is being expended on the development of a combined hot r cold forming process,which without sacriﬁcing the virtues of high yields and productivity will enable spur and helical gear forms to at least ISO Class5.2.Bevel gearsThe sequence of operations used in the initial commercial bevel gear forging process is shown in Fig. w x11.Of the six stages shown,slug preparation to ﬁnished gear,only two are forging.The billet was0261-3069r00r$-see front matterᮊ2000Elsevier Science Ltd.All rights reserved.Ž.PII:S0261-30699900074-6()T.A.Dean r Materials and Design 212000271᎐278272w x

would make this unnecessary nowadays.Fig.2shows the two-part forging die and the ﬂash that is inevitable on the back face of the part.This is often removed by machining although given that it provides a stiffening feature,designers are including it to produce higher performance products.A ﬂashless gear may be made in a toolset with a completely enclosed ually cold forging is employed to achieve ultimate accuracy.Orbital cold forging,in which the top tool is tilted from the vertical and rotates,is also used to make bevel gears.The smaller tool r workpiece contact area arising in this process enables machines with smallercapacities than conventional presses to be used to form gears of a particular size.3.Gear blanksIn contrast to bevel gears the tooth tips of spur and helical gears lie parallel to their axes.In gears where the ratio of tooth width to gear diameter is large,teeth can often be formed by extrusion.Parts such as starter motor pinions and splined shafts have been made by cold extrusion for many years.Examples are shown in Fig.3.If teeth extend the whole width of the gear,continual extrusion may be utilised in which a partly extruded component is fully pushed through the die by the following billet.The motion through the die is in one direction and high productivity can be achieved.Fig.4is an example of a gear made in this way showing the distortion that arises on the end faces due to the non-uniform metal ﬂow.Gears used for power transmitting gearboxes are usually thin compared with their diameters and often have other features such as grooves,and synchro cones on one face which makes them unsuitable for extru-sion.The method of manufacture most commonly used is forging heated workpieces in completely closed die cavities.Currently the forging of involute running teeth on this type of gear is not a commercially acceptable process because the teeth cannot be forged to ﬁnish dimensions.Problems associated with the subsequent handling and

running teeth is left blank and machined as for the traditional method.Fig.5shows photographs of warm forged gear blanks with dog teeth.The latter feature being essentially a spur gear is easily cold formed to ﬁnish size.Fig.6shows a traditional hot forged gear blank.The ﬂash and poor surface ﬁnish on this part are readily appar-ent and the lack of dimensional accuracy can be readily appreciated.In contrast the gears shown in Fig.5have a good surface ﬁnish,are dimensionally consistent and therefore can be automatically handled through ma-chining lines with conﬁdence.The layout of a typical forging line for the produc-w x tion of this type of gear blank is shown in Fig.72.The raw material is usually peeled steel bar to ensure dimensional accuracy and no surface

weighed.Typically they should be within 0.5%of nominal weight for forging in com-pletely closed cavity dies.Billets may be graded by weight and the heavier ones used later in the process as tool wear results in cavity growth.For high productiv-ity,heating,lubrication and forging are carried out sequentially and automatically in the line.Heating is by induction and in two stages.A short heater is used to take the temperature of the billets to a value between 120ЊC and 150ЊC.The billets are then sprayed or immersed in the lubricant which coats them with graphite as the carrier evaporates.The coated billets are then conveyed to the main heater which takes them to forging temperature.At least three forging opera-tions will be used.The ﬁrst to square and size the slug,one to pierce the hole and one to produce the ﬁnished shape,the workplace being fed automatically through the press.After forging,the parts will be cooledunderFig.6.Traditional hot forged gear blank.()T.A.Dean r Materials

temperature to within 15ЊC,die temperature to within 10ЊC,consistent application of lubricating coat-ing,is necessary to ensure the required accuracy of forged parts.4.Spur and helical gearsAlthough,as stated above gears with running teeth to a high order of accuracy,say ISO 5,cannot yet be formed on a commercial basis,vigorous R&D is under-way to achieve this goal.The state of the art and development strategy for precision gear forging in the w x Japanese automobile industry is shown in Fig.83.Here it is shown that bevel differential and dog teeth are achievable by current mass production forming technologies.Internal spline gears for four-wheel drive vehicles,automatic transmission gears and gearsforw x Fig.8.State-of-the-art of gear forging technology 3.manual transmission gearboxes are still in the develop-ment stage.A useful design of die for the production of either spur or helical gear forms is shown schematically in Fig.9.A hollow workpiece is being deformed between punch and counterpunch in a completely closed cavity die.It is constrained at its bore by a mandrel attached to the punch and its peripheral surface is ﬂowing into the teeth in the container wall.Under the action of the punch the container moves downwards,guided by the counterpunch.Because the container is completely closed,no ﬂash is formed,but because the workpieces have to be heated to enable them to ﬂow into the recesses of the die cavity,the teeth are not formed to net-shape.Fig.10is a photograph of an automotive gear made in a die of similar construction.The dividing of the metal ﬂow to form both teeth and synchro cone features on this gear makes die ﬁlling easier than for the simple helical gear shown in Fig.11.5.AccuracyThe accuracy of forged teeth is dominated by the accuracy of the die and the designed dimensions of dies are affected essentially by the three factors shown in w x Fig.124for a circular shape.They are:elastic expan-sion due to forging pressures U ;thermal;expansion e U ;when forgings are undertaken at elevated tempera-t tures and the contraction of a heated forging as it returns to room temperature after removal from the die.The dimension G shown in Fig.12indicates the spark gap allowance that must be used if the die cavity is made by EDM.The desired dimension R is ob-o tained by allowing for the cumulative affect of the()T.A.Dean r Materials and Design 212000271᎐278275pletely-closed cavity toolset for gear forging.three above factors.The relative size of these effects can be judged from Fig.13which refers to a cylindrical forging of nominal diameter 63.5mm.The elastic ex-pansion of the die decreases as forging temperature rises because lower die wall pressures arise.The higher the forging temperature the greater the thermal expan-sion of the die.The factor with the largest effect on dimensions is the thermal contraction of the forging.It is obvious that high accuracy can be achieved only if values of temperature and pressure in the process are consistent and the greatest accuracies are obtained when workpieces are not preheated.To improve the accuracy of spur and helical gears forged at elevated temperatures,cold sizing operations w x have been proposed and are being investigated 5,6.An investigation at the author’s universityindicatesFig.10.Automotive gear forged in completely-closed

its surface with a phos-phate r stearate combination.Ironing basically consists of forcing the oversize gear through the die as illus-trated.Only a thin outer layer of the tooth form is deformed.The tooth proﬁle on the ironing die is calcu-lated from computer process simulation.In an experi-ment undertaken by the author the surface of the tooth form was ﬁnished to 0.5␮m RMS.The gear teeth were 0.1mm oversize and induction hardened to H 570v with a core hardness of H 290.The results shown in v Table 1show that apart from tooth trace,errors exist-ing in the forged gears were considerably reduced by ironing.A surface ﬁnish of the teeth of approximately 1␮m RMS was obtained.In general,the quality of the gears was improved by approximately two classes on the AGMAscale.Fig.14.Schematic of

choosing different process conditions may be sum-marised as follows:ⅷGrainﬂow follows the tooth proﬁle and grain size tends to be smaller nearer the surface of the gear teeth,due to the greater deformation in this region.ⅷHeating in normal atmosphere tends to cause de-carburization which is greater at the teeth tips.ⅷGears of suitable alloys may be quench-hardened from the forging temperature.Small tooth sizes are readily through-hardened.ⅷPre-carburised billets may be forged but heating must be performed in a non-oxidising atmosphere to avoid loss of carbon.The high carbon layer tends to diffuse inwards on heating and thickens at the teeth tips during forging.The dynamic strength of forged tooth forms can be greater than that of gears made by conventional meth-ods.This is illustrated in the case of impact strengthfor BS817M40steel gears hardened to H300invw xTable26.It is clear that the impact strength of fully forged gear teeth is approximately30%higher than that of gear teeth either machined from forged blanks or from rolled bar.The results of fatigue tests undertaken on gears ofw xBS817M40steel are shown in Figs.15and168.The formerﬁgure shows results for gears through-hardenedto H250and the latter for gears induction-hardened vto H570to5mm below the surface with a core vhardness of H290.It is apparent that the fatigue limitvof forged gears is signiﬁcantly higher than that of the cut gears.Due to the fact that after heat treatment the toothﬂanks were ground only above the base circle the root surface of the forged gears was rougher than that of the cut gears.To provide equivalence the root surface of some forged gears were hand-polished.These are referred to as‘forged andﬁnished’and the results shown in Fig.15show their fatigue strength is the highest.The fatigue strength of induction-hardened forged gears is higher than that of gears eithercut fromforged blanks or from rolled bar.The relative rankingof fatigue strengths shown in Fig.16is similar to thatfor impact resistance.7.Concluding remarksForging technology is at the stage where bevel gearsmay be formed to net-shape.Spur and helical gears ofcertain envelope

Case StudyAt a Glance IndustryChallengeCreate a seamless end-user experience and streamline backend services while moving business-critical solutions to AWS cloud environmentProducts and ServicesNetIQ Identity Manager NetIQ Access Manager NetIQ Identity GovernanceNetIQ Advanced AuthenticationSuccess Highlights• E nriched functionality and seamless access across hybrid environment • Reduced business complexity with seamless end-user experience • Introduced Cloud Bridge for full bi-directional communication in hybrid environment • Increased scalability, flexibility, and cost-predictability with AWS deploymentOpenTextNetIQ supports global digital transformation totransparently bridge business-critical solutions hosted on premises and in AWS cloud environment.Who is OpenText?OpenText™ is one of the world’s largest enterprise software providers. It delivers mission-critical technology and supporting services that help thousands of customers worldwide manage core IT elements of their business so they can run and transform— at the same time. Cyberscurity is an OpenT ext™ line of business.Digital Transformation Drives Move to a SaaS Application ModelOpenText, like many of its customers, is a large organization grown significantly through acquisition. This strategy brought a plethora of tools used in different divisions. T o standardize its corporate identity management, OpenText trusts its own suite of identity and access solutions, under the NetIQ banner. NetIQ Identity Manager by OpenText™ and Access Manager by OpenText™ wereIT-managed in an on-premises environment and evolved more recently to include NetIQ Advanced Authentication by OpenText™ for multi-factor authentication as well as effective website protection.The merger between Micro Focus and HPE Software tripled the size of the organization and introduced new challenges around data hygiene, audit compliance, and security in general. At the same time, there was a definite market move towards a preference forSaaS-based solutions, to relieve the burden and cost of maintaining an on-premises IT environment. Jon Bultmeyer, CTO,Cybersecurity, runs the engineering teams involved in building Cybersecurity SaaS offerings. He works closely with other OpenText teams on the customer delivery model as well as the internal delivery of SaaS versions. He explains: “We found that we were lagging a little in version-currency, just because of the workload involved in an upgrade. To secure, run, and operate a large-scale identity management operation for over 12,000 staff is labor-intensive and time-consuming. This seemed a good opportunity to embrace the digital transformation at the heart of Micro Focus (now part of OpenText) and move our identity and access architecture to an AWS-hosted cloud environment.”“Cloud Bridge really streamlines the transition to SaaS and gives us the observability we need to ensure effective data flows between different systems.”Jon Bultmeyer CTOCyberResOpenTextIntroduce New Functionality and Comprehensive Access Reviewsin Hybrid EnvironmentOpenText took a wider view and introduced the SaaS Center of Excellence (CoE) organization, headed up by David Gahan, Senior Director, Cybersecurity SaaS. Rather than just make a ‘like for like’ move, the team chose to enhance the platform with NetIQ Identity Governance by OpenText™,as well as expanding the NetIQ Advanced Authentication by OpenText™ capability into a SaaS model. Pivoting from a ‘governance first’ principle with a focus on application access reviews, the project aimed to move via automated application access and approval to fully automated application access request and enablement.The full solution would provide seamless connectivity to the company’s key applications: Salesforce to manage customer interactions and order processing; Workday as an integrated HR solution; and NetSuite, which manages business finances and operational support, as well as other business-critical applications. It would also provide the capability to conduct certification reviews. This automated process builds a comprehensive directory of who has access to what. Periodically, all process and solution owners are asked to review their access list for accuracy. Job roles determine the level of access to specific solutions required for individuals. This ‘least privilege’ principle ensures that only colleagues with the right access level can configure the finance platform, for instance, or reach confidential personnel data in Workday.The project was part of the corporate digital transformation and as such had an executive spotlight on it, coupled with a tight delivery deadline of no more than 12 months. Cloud Bridge: Managing FullyIntegrated Identity Governancein a Hybrid EnvironmentOpenText’s own Professional Services skillsand their specific expertise in building thesesystems for Cybersecurity customers wasinvaluable. The SaaS CoE team workedon creating the SaaS infrastructure, andBultmeyer’s engineering teams werebuilding the SaaS applications. Meanwhile,Professional Services implemented NetIQIdentity Governance on premises to kickstartthe application integration, which relied onmany interconnected parts. Because theday-to-day business running takes ultimatepriority, this was a ‘run and transform’ scenariowith a hybrid approach. Key business systemsmoved in phases to the SaaS environmentwhile others remained on premises fornow. It is a challenge to integrate identitygovernance between on-premises and SaaS-based systems, and Cybersecurity wantedfully automated event-driven integration—they recognized that the manual process ofeither CSV file transfers or site-to-site VPNconnections that are offered by some marketalternatives can cause firewall complexities.As this, again, is not a challenge that isunique to OpenText, Bultmeyer’s teamturned its attention to creating the OpenTextCloud Bridge, as he explains: “Cloud Bridgeis a singular communication bridge for allour Cybersecurity SaaS solutions. It allowssecure bi-directional communication betweenon-premises and SaaS systems via a Dockercontainer. There are no special rules whenconfiguring the Cloud Bridge agent,so communication between on-premisesand cloud-based systems can be up andrunning within just an hour. There is just asingle location to monitor, so any issuesare resolved quickly. Cloud Bridge reallystreamlines the transition to SaaS and gives usthe observability we need to ensure effectivedata flows between different systems.”Reduced Business ComplexityWhile Navigating COVID-19Working PracticesOnce the CoE SaaS infrastructure wasoperational, the Professional Services teamtransitioned the on-premises NetIQ IdentityGovernance implementation to the AWSenvironment. The identity governanceenvironment now includes end-to-endintegrated workflows between key systems,integrated password management, singlesign-on, full visibility through Cloud Bridge,and advanced analytics leveraging OpenText™Vertica™ capabilities. Gahan says: “Leveragingour own NetIQ [by OpenText] solutions in aSaaS environment has allowed us to createa seamless end-user experience wherewe were once living in a world made up ofdifferent islands of access. The solutions ouremployees use to service our customers’needs and our own internal needs have beenstandardized, drastically reducing businesscomplexity across the board. It’s given usterrific backend benefits as well by helpingsimplify and standardize the concepts ofidentity and access acrossall of our business units.”“The project timelines coincided with theCOVID-19 pandemic, which presented uswith the same challenges our customersexperienced around the world,” addsBultmeyer. “Suddenly we could no longergather around a whiteboard to brainstorm,and we had to quickly adjust to workingremotely. Thankfully, this didn’t deter ourdetermination, and many teams—includingour Micro Focus (now part of OpenText) ITteam, the dedicated project implementationteam, our product management teams,backline engineering teams, the newlyformed CoE team, and our Customer Successteams—worked seamlessly together toadjust the implementation and manage anyproblems we encountered along the way.”2Enriched Functionalityand Cost Predictability in Flexible AWS DeploymentGahan spearheads the SaaS CoE, a new global organization dedicated to supporting SaaS customers. Leveraging expertise on defining governance policies, designingthe solution, and configuring this in a SaaS environment, the team created a truly hybrid identity governance platform where the end user does not know, nor need to care, whether the data they access resides on-premises or in the cloud. “And this is just how it should be,” Gahan says. “Our end users now benefit from much richer functionality such as seamless multi-factor authentication and sophisticated access review processes, drastically reducing manual processes.”Bultmeyer concludes: “NetIQ [by OpenText™] solutions have simplified our identity governance and shortened our communication lines. We were excited to leverage our strategic partnership with AWS, giving us a scalable and cost-predictable model as we grow, and allowing us to roll out additional functionality much faster than we otherwise could have done.”“NetIQ [by OpenText™] solutions have simplified our identitygovernance and shortened our communication lines.We were excited to leverage our strategic partnership withAWS, giving us a scalable and cost-predictable model aswe grow, and allowing us to roll out additional functionalitymuch faster than we otherwise could have done.”Jon BultmeyerCTOCyberResOpenText Cybersecurity provides comprehensive security solutions for companies and partners of all sizes.

NetBIOS的工作过程
• 在网络中使用NetBIOS名称时，基本工作过程包括 NetBIOS名称的注册、释放和查询。
• NetBIOS名称的注册是在计算机启动、服务开始或用户登录时动态进行的。当计算机正常关闭、服务正常停止或用户正常退出时，将会进行NetBIOS名称的释放。如果一个计算机试图通过NetBIOS名称访问另一台计算机时，需要进行 NetBIOS名称查询，以便能够正常通信。NetBIOS名称的注册及释放实质上都是为名称查询服务的。
• NetBEUI协议在早期的Windows操作系统中使用非常普遍，但由于其不支持路由且所有通信均通过广播，只能应用于范围很小的网络中。因此，在目前的网络中，已经基本不再使用NetBEUI协议来支持NetBIOS，在Windows Server 2008 中，默认也不再提供NetBEUI协议，取而代之的是TCP/IP协议。
