阿尔伦-布拉德利 Stratix 5700 工业 managed Ethernet 交换机说明书

Stratix 5700Industrial Managed Ethernet SwitchThe wide deployment of EtherNet/IP™ in industrial automation means that there is a growing demand to manage the network properly.Integtrating new machine-level networks into an existing plant network requires convergence.With more devices connected on the same Ethernet network than ever before, an industrial managed switch can help you simplify your network infrastructure. Adding a managed switch to your network architecture can also help make the process of adding new machines easier. The Allen-Bradley® Stratix 5700™ is a compact, scalable Layer 2 managed switch with embedded Cisco technology for use in applications with small isolated, to complex networks. With integration into Studio 5000 Automation Engineering and Design Environment™, you canleverage FactoryTalk® View faceplates and Add-on Profiles for simplified configuration and monitoring.By choosing a switch co-developed by Rockwell Automation and Cisco, your Operations Technology (OT) and Information Technology (IT) professionals leverage tools and technology that are familiar to them. This collaboration can also help to reduce configuration time and cost.Features and Benefits:Advanced Networking Features• Integrated Device Level Ring (DLR) connectivity helps optimize the network architecture and provide consolidated network diagnostics • Integrated Network Address Translation (NAT) provides 1:1 IP address mapping helping to reduce commissioning time • Power over Ethernet (PoE) versions provide power to devices over Ethernet minimizing cabling • Security features, including access control lists, help ensure that only authorized devices, users and traffic can access the network • Secure Digital (SD) card provides simplified device replacementOptimized integration:• Studio 5000® Add-on Profiles (AOPs) enable premier integration into the Rockwell Automation Integrated Architecture® system • Predefined Logix tags for monitoring and port control • FactoryTalk® View faceplates enable status monitoring and alarming • Built-in Cisco® Internet Operating System (IOS) helps provide secure integration with enterprise networkDesigned and Developed for EtherNet/IP Automation ApplicationsNetwork Address TranslationMachine integration onto a plant network architecture can be difficult as machine builder IP-address assignments rarely match the addresses of the end-user network. Also, network IP addresses are often unknown until the machine is being installed. The Stratix 5700 with Network Address Translation (NAT) is a Layer 2 implementation that provides “wire speed” 1:1 translations ideal for automation applications where performance is critical.NAT allows for:• Simplified integration of IP-addressmapping from a set of local,machine-level IP addresses to theend user’s broader plant network• OEMs to deliver standard machinesto end users without programmingunique IP addresses• End users to more simply integratethe machines into the larger network192.168.1.4192.168.1.4MACHINE 1MACHINE 2Private Network Private NetworkSwitch Reference ChartAllen-Bradley Stratix 5700 Industrial Ethernet SwitchSwitch Selection TableFE - Fast Ethernet GE - Gigabit EthernetPublication ENET-PP005F-EN-E – April 2016Copyright ©2016 Rockwell Automation, Inc.

THINK. SOLVE., Powerflex, Rockwell Automation, Rockwell Software, Stratix 5700, Studio 5000, Studio 5000 Automation Engineering and Design Environment are trademarks of Rockwell Automation, Inc.Glossary of TermsAccess Control Lists allow you to filter network traffic. This can be used to selectively block types of traffic to provide traffic flow control or provide a basic level of security for accessing your network.CIP port control and fault detection allows for port access based on Logix controller program or controller mode (idle/fault). Allows secure access to the network based on machine conditions.CIP SYNC (IEEE1588) is the ODVAimplementation of the IEEE 1588 precision time protocol. This protocol allows very high precision clock synchronization across automation devices. CIP SYNC is an enabling technology for time-critical automation tasks such as accurate alarming for post-event diagnostics, precision motion and high precision first fault detection or sequence of events.Device Level Ring (DLR) allows direct connectivity to a resilient ring network at the device level.DHCP per port allows you to assign a specific IP address to each port, confirming that the device attached to a given port will get the same IP address. This feature allows for device replacement without having to manually configure IP addresses.Encryption provides network security by encrypting administrator traffic during Telnet and SNMP sessions.EtherChannel is a port trunking technology. EtherChannel allows grouping several physical Ethernet ports to create one logical Ethernet port. Should a link fail, the EtherChannel technology will automatically redistribute traffic across the remaining links.Ethernet/IP (CIP) interface enables premier integration to the Integrated Architecture with Studio 5000 AOP , Logix tags and View Faceplates.FlexLinks provides resiliency with a quick recovery time and load balancing on a redundant star network.IGMP Snooping (Internet Group Management Protocol) constrains the flooding of multicast traffic by dynamically configuring switch ports so that multicast traffic is forwarded only to ports associated with a particular IP multicast group.* Separate SW IOS requiredKey Software FeaturesMAC ID Port Security checks the MAC ID of devices connected to the switch to determine if it is authorized. If not the device is blocked and the controller receives a warning message. This provides a method to block unauthorized access to the network.Network Address Translation (NAT) provides 1:1 translations of IP addresses from one subnet to another. Can be used to integrate machines into an existing network architecture.Port Thresholds(Storm control & Traffic Shaping)allows you to set both incoming and outgoing traffic limits. If a threshold is exceeded alarms can be set in the Logix controller to alert an operator. Power over Ethernet (PoE) provides electrical power along with data on a single Ethernet cable to end devices.QoS – Quality of Service (QoS) is the ability to provide different priority to different applications, users, or data flows, to help provide a higher level of determinism on your network.REP (Resilient Ethernet Protocol) – A ring protocol that allows switches to be connected in a ring, ring segment or nested ring segments. REP provides network resiliency across switches with a rapid recovery time ideal for industrial automation applications.Smartports provide a set of configurations to optimize port settings for common devices like automation devices, switches, routers, PCs and wireless devices. Smartports can also be customized for specific needs.SNMP Simple Network Management Protocol (SNMP) is a management protocol typically used by IT to help monitor and configure network-attached devices.Static and InterVLAN Routing bridges the gap between layer 2 and layer 3 routing providing limited static and connected routes across VLANs.STP/RSTP/MST Spanning Tree Protocol, is a feature that provides a resilient path between switches. Used for applications that requires a fault tolerant network.VLANs with Trunking is a feature that allows you to group devices with a common set of requirements into network segments. VLANs can be used to provide scalability, security and management to your network.802.1x Security is an IEEE standard for access control and authentication. It can be used to track access to network resources and helps secure the network infrastructure.。

peripheral 159160devices that adhere to MIPI Alliance specifications for mobile device interfaces. The DSI specification 161builds on existing standards by adopting pixel formats and command set defined in MIPI Alliance 162standards for DBI-2 [2], DPI-2 [3], and DCS [1].1.1 Scope163Interface protocols as well as a description of signal timing relationships are within the scope of this 164165specification.166Electrical specifications and physical specifications are out of scope for this document. In addition, legacy interfaces such as DPI-2 and DBI-2 are also out of scope for this specification. Furthermore, device usage 167168of auxiliary buses such as I2C or SPI, while not precluded by this specification, are also not within its 169scope.1.2 Purpose170171The Display Serial Interface specification defines a standard high-speed serial interface between a 172peripheral, such as an active-matrix display module, and a host processor in a mobile device. By 173standardizing this interface, components may be developed that provide higher performance, lower power, 174less EMI and fewer pins than current devices, while maintaining compatibility across products from 175multiple vendors.2 Terminology (Informational)176177The MIPI Alliance has adopted Section 13.1 of the IEEE Standards Style Manual, which dictates use of the 178words “shall”, “should”, “may”, and “can” in the development of documentation, as follows:179The word shall is used to indicate mandatory requirements strictly to be followed in order to conform to the standard and from which no deviation is permitted (shall equals is required to).180181The use of the word must is deprecated and shall not be used when stating mandatory requirements; must is 182used only to describe unavoidable situations.183The use of the word will is deprecated and shall not be used when stating mandatory requirements; will is 184only used in statements of fact.185The word should is used to indicate that among several possibilities one is recommended as particularly 186suitable, without mentioning or excluding others; or that a certain course of action is preferred but not 187necessarily required; or that (in the negative form) a certain course of action is deprecated but not 188prohibited (should equals is recommended that).189The word may is used to indicate a course of action permissible within the limits of the standard (may 190equals is permitted).191The word can is used for statements of possibility and capability, whether material, physical, or causal (can 192equals is able to).193All sections are normative, unless they are explicitly indicated to be informative.2.1 Definitions194195Forward Direction: The signal direction is defined relative to the direction of the high-speed serial clock. 196Transmission from the side sending the clock to the side receiving the clock is the forward direction.197Half duplex: Bidirectional data transmission over a Lane allowing both transmission and reception but 198only in one direction at a time.199HS Transmission: Sending one or more packets in the forward direction in HS Mode. A HS Transmission 200is delimited before and after packet transmission by LP-11 states.201Host Processor: Hardware and software that provides the core functionality of a mobile device.Lane: Consists of two complementary Lane Modules communicating via two-line, point-to-point Lane 202203Interconnects. A Lane is used for either Data or Clock signal transmission.204Lane Interconnect: Two-line point-to-point interconnect used for both differential high-speed signaling 205and low-power single ended signaling.206Lane Module: Module at each side of the Lane for driving and/or receiving signals on the Lane.207Link: A complete connection between two devices containing one Clock Lane and at least one Data Lane. 208LP Transmission: Sending one or more packets in either direction in LP Mode or Escape Mode. A LP 209Transmission is delimited before and after packet transmission by LP-11 states.Packet: A group of two or more bytes organized in a specified way to transfer data across the interface. All 210211packets have a minimum specified set of components. The byte is the fundamental unit of data from which 212packets are made.213Payload: Application data only – with all Link synchronization, header, ECC and checksum and other 214protocol-related information removed. This is the “core” of transmissions between host processor and 215peripheral.216PHY: The set of Lane Modules on one side of a Link.217PHY Configuration: A set of Lanes that represent a possible Link. A PHY configuration consists of a 218minimum of two Lanes: one Clock Lane and one or more Data Lanes.219Reverse Direction: Reverse direction is the opposite of the forward direction. See the description for 220Forward Direction.221Transmission: Refers to either HS or LP Transmission. See the HS Transmission and LP Transmission 222definitions for descriptions of the different transmission modes.223Virtual Channel: Multiple independent data streams for up to four peripherals are supported by this 224specification. The data stream for each peripheral is a Virtual Channel. These data streams may be 225interleaved and sent as sequential packets, with each packet dedicated to a particular peripheral or channel. 226Packet protocol includes information that directs each packet to its intended peripheral.227Word Count: Number of bytes.2.2 Abbreviations228229e.g. Forexample2.3 Acronyms230231AM Active matrix (display technology)232ProtocolAIP ApplicationIndependent233ASP Application Specific Protocol234BLLP Blanking or Low Power intervalPixel235perBPP Bits236Turn-AroundBTA Bus237InterfaceCSI CameraSerial238DBI Display Bus InterfaceDI Data239Identifier240DMA Direct Memory Access241DPI Display Pixel InterfaceDSIDisplay Serial Interface242 DT Data Type243 ECC Error-Correcting Code 244 EMI Electro Magnetic interference 245 EoTEnd of Transmission246 ESD Electrostatic Discharge 247 FpsFrames per second248 HS High Speed 249 ISTOIndustry Standards and Technology Organization250 LLP Low-Level Protocol 251 LP Low Power 252 LPI Low Power Interval 253 LPS Low Power State (state of serial data line when not transferring high-speed serial data) 254 LSBLeast Significant Bit255 Mbps Megabits per second256 MIPI Mobile Industry Processor Interface 257 MSBMost Significant Bit258 PE Packet End 259 PF Packet Footer 260 PH Packet Header 261 PHY Physical Layer 262 PI Packet Identifier 263 PPI PHY-Protocol Interface 264 PS Packet Start 265 PT Packet Type 266 PWB Printed Wired Board267 QCIFQuarter-size CIF (resolution 176x144 pixels or 144x176 pixels)268 QVGA Quarter-size Video Graphics Array (resolution 320x240 pixels or 240x320 pixels)269RAM Random Access Memory270271RGB Color presentation (Red, Green, Blue)272SLVS Scalable Low Voltage Signaling273SoT Start of Transmission274SVGA Super Video Graphics Array (resolution 800x600 pixels or 600x800 pixels) 275VGA Video Graphics Array (resolution 640x480 pixels or 480x640 pixels)VSA Vertical276ActiveSync277WVGA Wide VGA (resolution 800x480 pixels or 480x800 pixels)278CountWC Word3 References (Informational)279280[1] MIPI Alliance Standard for Display Command Set, version 1.00, April 2006281[2] MIPI Alliance Standard for Display Bus Interface, version 2.00, November 2005[3] MIPI Alliance Standard for Display Parallel Interface, version 2.00, September 2005282283[4] MIPI Alliance Standard for D-PHY, version 0.65, November 2005284Design and Analysis of Fault Tolerant Digital System by Barry W. Johnson285Error Correcting Codes: Hamming Distance by Don Johnson paper286Intel 8206 error detection and correction unit datasheet287National DP8400-2 Expandable Error Checker/Corrector datasheetMuch of DSI is based on existing MIPI Alliance standards as well as several MIPI Alliance standards in 288289simultaneous development. In the Application Layer, DSI duplicates pixel formats used in MIPI Alliance 290Standard for Display Parallel Interface [3] when it is in Video Mode operation. For display modules with a 291display controller and frame buffer, DSI shares a common command set with MIPI Alliance Standard for 292Display Bus Interface [2]. The command set is documented in MIPI Alliance Standard for Display 293Command Set [1].3.1 DBI and DBI-2 (Display Bus Interface Standards for Parallel Signaling)294295DBI and DBI-2 are MIPI Alliance specifications for parallel interfaces to display modules having display 296controllers and frame buffers. For systems based on these specifications, the host processor loads images to 297the on-panel frame buffer through the display processor. Once loaded, the display controller manages all 298display refresh functions on the display module without further intervention from the host processor. Image 299updates require the host processor to write new data into the frame buffer.300DBI and DBI-2 specify a parallel interface; that is, data is sent to the peripheral over an 8-, 9- or 16-bit-301wide parallel data bus, with additional control signals.302The DSI specification supports a Command Mode of operation. Like the parallel DBI, a DSI-compliant 303interface sends commands and parameters to the display. However, all information in DSI is first serialized 304before transmission to the display module. At the display, serial information is transformed back to parallel 305data and control signals for the on-panel display controller. Similarly, the display module can return status 306information and requested memory data to the host processor, using the same serial data path.3.2 DPI and DPI-2 (Display Pixel Interface Standards for Parallel Signaling)307DPI and DPI-2 are MIPI Alliance specifications for parallel interfaces to display modules without on-panel 308309display controller or frame buffer. These display modules rely on a steady flow of pixel data from host 310processor to the display, to maintain an image without flicker or other visual artifacts. MIPI Alliance 311specifications document several pixel formats for Active Matrix (AM) display modules.312Like DBI and DBI-2, DPI and DPI-2 are specifications for parallel interfaces. The data path may be 16-, 31318-, or 24-bits wide, depending on pixel format(s) supported by the display module. This specification 314refers to DPI mode of operation as Video Mode.Some display modules that use Video Mode in normal operation also make use of a simplified form of 315316Command Mode, when in low-power state. These display modules can shut down the streaming video 317interface and continue to refresh the screen from a small local frame buffer, at reduced resolution and pixel318depth. The local frame buffer shall be loaded, prior to interface shutdown, with image content to be319displayed when in low-power operation. These display modules can switch mode in response to power-320control commands.3.3 DCS (Display Command Set)321322DCS is a specification for the command set used by DSI and DBI-2 specifications. Commands are sent 323from the host processor to the display module. On the display module, a display controller receives andinterprets commands, then takes appropriate action. Commands fall into four broad categories: read 324325register, write register, read memory and write memory. A command may be accompanied by multiple 326parameters.3.4 CSI-2 (Camera Serial Interface 2)327CSI-2 is a MIPI Alliance standard for serial interface between a camera module and host processor. It is 328329based on the same physical layer technology and low-level protocols as DSI. Some significant differencesare:330331•CSI-2 uses unidirectional high-speed Link, whereas DSI is half-duplex bidirectional Link332•CSI-2 makes use of a secondary channel, based on I2C, for control and status functions333CSI-2 data direction is from peripheral (Camera Module) to host processor, while DSI’s primary data334direction is from host processor to peripheral (Display Module).3.5 D-PHY (MIPI Alliance Standard for Physical Layer)335MIPI Alliance Standard for D-PHY [4] provides the physical layer definition for DSI. The functionality 336337specified by the D-PHY standard covers all electrical and timing aspects, as well as low-level protocols, 338signaling, and message transmissions in various operating modes.4 DSI Introduction339340DSI specifies the interface between a host processor and a peripheral such as a display module. It builds on 341existing MIPI Alliance standards by adopting pixel formats and command set specified in DPI-2, DBI-2 342and DCS standards.343Figure 1 shows a simplified DSI interface. From a conceptual viewpoint, a DSI-compliant interface 344performs the same functions as interfaces based on DBI-2 and DPI-2 standards or similar parallel display 345interfaces. It sends pixels or commands to the peripheral, and can read back status or pixel information 346from the peripheral. The main difference is that DSI serializes all pixel data, commands, and events that, in 347traditional or legacy interfaces, are normally conveyed to and from the peripheral on a parallel data bus 348with additional control signals.349From a system or software point of view, the serialization and deserialization operations should be 350transparent. The most visible, and unavoidable, consequence of transformation to serial data and back to 351parallel is increased latency for transactions that require a response from the peripheral. For example, 352reading a pixel from the frame buffer on a display module will have a higher latency using DSI than DBI. 353Another fundamental difference is the host processor’s inability during a read transaction to throttle the 354rate, or size, of returned data.355356Figure 1 DSI Transmitter and Receiver Interface4.1 DSI Layer Definitions357Application Processor Peripheral358Figure 2 DSI Layers359360A conceptual view of DSI organizes the interface into several functional layers. A description of the layers 361follows and is also shown in Figure 2.362PHY Layer: The PHY Layer specifies transmission medium (electrical conductors), the input/output 363circuitry and the clocking mechanism that captures “ones” and “zeroes” from the serial bit stream. This part 364of the specification documents the characteristics of the transmission medium, electrical parameters for 365signaling and the timing relationship between clock and Data Lanes.366The mechanism for signaling Start of Transmission (SoT) and End of Transmission (EoT) is specified, as 367well as other “out of band” information that can be conveyed between transmitting and receiving PHYs. 368Bit-level and byte-level synchronization mechanisms are included as part of the PHY. Note that the 369electrical basis for DSI (SLVS) has two distinct modes of operation, each with its own set of electrical 370parameters.371The PHY layer is described in MIPI Alliance Standard for D-PHY [4].372Lane Management Layer: DSI is Lane-scalable for increased performance. The number of data signals 373may be 1, 2, 3, or 4 depending on the bandwidth requirements of the application. The transmitter side of the 374interface distributes the outgoing data stream to one or more Lanes (“distributor” function). On the receiving end, the interface collects bytes from the Lanes and merges them together into a recombined data 375376stream that restores the original stream sequence (“merger” function).Protocol Layer: At the lowest level, DSI protocol specifies the sequence and value of bits and bytes 377378traversing the interface. It specifies how bytes are organized into defined groups called packets. The 379protocol defines required headers for each packet, and how header information is generated and interpreted.The transmitting side of the interface appends header and error-checking information to data being 380381transmitted. On the receiving side, the header is stripped off and interpreted by corresponding logic in the 382receiver. Error-checking information may be used to test the integrity of incoming data. DSI protocol also383documents how packets may be tagged for interleaving multiple command or data streams to separate384destinations using a single DSI.385Application Layer: This layer describes higher-level encoding and interpretation of data contained in the386data stream. Depending on the display subsystem architecture, it may consist of pixels having a prescribed387format, or of commands that are interpreted by the display controller inside a display module. The DSI 388specification describes the mapping of pixel values, commands and command parameters to bytes in the389packet assembly. See MIPI Alliance Standard for Display Command Set [1].4.2 Command and Video Modes390391DSI-compliant peripherals support either of two basic modes of operation: Command Mode and Video392Mode. Which mode is used depends on the architecture and capabilities of the peripheral. The mode393definitions reflect the primary intended use of DSI for display interconnect, but are not intended to restrict 394DSI from operating in other applications.Typically, a peripheral is capable of Command Mode operation or Video Mode operation. Some Video 395396Mode displays also include a simplified form of Command Mode operation in which the display may 397refresh its screen from a reduced-size, or partial, frame buffer, and the interface (DSI) to the host processor398may be shut down to reduce power consumption.Mode3994.2.1 Command400Command Mode refers to operation in which transactions primarily take the form of sending commands401and data to a peripheral, such as a display module, that incorporates a display controller. The display 402controller may include local registers and a frame buffer. Systems using Command Mode write to, and readfrom, the registers and frame buffer memory. The host processor indirectly controls activity at the 403404peripheral by sending commands, parameters and data to the display controller. The host processor can also 405read display module status information or the contents of the frame memory. Command Mode operationrequires a bidirectional interface.406407Operation4.2.2 VideoMode408Video Mode refers to operation in which transfers from the host processor to the peripheral take the form of409a real-time pixel stream. In normal operation, the display module relies on the host processor to provide410image data at sufficient bandwidth to avoid flicker or other visible artifacts in the displayed image. Video 411information should only be transmitted using High Speed Mode.412Some Video Mode architectures may include a simple timing controller and partial frame buffer, used to413maintain a partial-screen or lower-resolution image in standby or low-power mode. This permits the 414interface to be shut down to reduce power consumption.415To reduce complexity and cost, systems that only operate in Video Mode may use a unidirectional data416path.。

2021年CCNA笔记 EIGRP AND OSPF(一)

CCNA笔记 EIGRP and OSPF（一）Enhan ___d IGRP(EIGRP) and Open Shortest Path First(OSPF)EIGRP Features and OperationEIGRP是1种无分类(classless),增强的距离向量路由协议,和IGRP类似,EIGRP也使用AS,但是和IGRP不同的是,EIGRP在它的路由更新信息中要包含子网掩码的信息.这样,在我们设计的网络的时候,就允许我们使用VL ___和sum ___rization.EIGRP有时候也算是混合型路由协议,因为它同时具有了距离向量路和链路状态的一些特征:比如它不像OSPF那样发送链路状态包而发送传统的距离向量更新;EIGRP也有链路状态协议的特征比如它在相邻router启动的时候同步路由表,然后只在拓扑结构发生变化的时候发送1些更新.这样就使得EIGRP能够很好的在1个大型网络中工作.EIGRP支持的跳数多达255.EIGRP的主要特点如下: 1.通过PDMs(Protocol-Dependent Module)来支持IP,IPX和AppleTalk 2.有效的邻router的发现 3.通过可靠传输协议(Reliable Transport Protocol,RTP)进行通讯 4.通过扩散更新算法(Diffusing Update Algorithm,DUAL)来选择最佳路径Protocol-Dependent ModuleEIGRP的1大特点是它可以支持几种网络层协议:IP,IPX和AppleTalk等.能像EIGRP那样支持数种网络层协议的还有Intermediate System-to-Intermediate System(IS-IS)协议,但是这个协议只支持IP和Connectionless Network Servi___(CLNS).EIGRP通过PDMs来支持不同的网络层协议.每个EIGRP 的PDM保持1个单独的路由信息表来装载某种协议(比如IP)的路由信息.也就是有IP/EIGRP表,IPX/EIGRP的表和AppleTalk/EIGRP表Neighbor Discovery在运行了EIGRP的router彼此进行交换信息之前,它们首先必须成为邻居(neighbor).建立邻居关系必须满足以下3个条件:1.Hello信息或接受收ACK2.AS号匹配3.K值链路状态协议趋向于使用Hello信息来建立邻居关系,它不会像距离向量那样周期性的发送路由更新.为了保持邻居关系,运行了EIGRP的router必须持续从邻居那里收到Hellos如果不在1个AS内,router之间是不会共享路由信息的,也不会建立邻居关系.这样做的优点是在大型网络中可以减少特定某个AS 内路由信息的传播当EIGRP发现新邻居的时候,就开始通告整个路由表给别的router,当所有的router都知道新成员的加入,学习到新的路径以后,从那开始,路由表中有变动的部分才会传播给别的router.当router接收到邻居的更新以后,把它们保存在本地数据库表里看下几个术语: 1.可行距离(feasible distan ___):到达一个目的地的最短路由的度 2.后继(suessor):后继是一个直接连接的邻居router,通过它具有到达目的地的最短路由.通过后继router 将包转发到目的地 3.通告距离(reported distan ___):相邻router所通告的相邻router自己到达某个目的地的最短路由的度4.可行后继(feasible suessor):可行后继是一个邻居router,通过它可以到达目的地,不使用这个router是因为通过它到达目的地的路由的度比其他router高,但它的通告距离小于可行距离,因而被保存在拓扑表中,用做备择路由Reliable Transport Protocol(RTP)EIGRP使用一种叫做RTP的私有协议,来管理使用了EIGRP的router之间的通信,如RTP的名字,可靠(reliable)即为这个协议的关键.RTP负责EIGRP数据包到所有邻居的有保证和按顺序的传输.它支持多目组播或单点传送数据包的混合传输/出于对效率的考虑.只有某些E IGRP数据包被保证可靠传输.RTP确保在相邻router间正在进行的通信能够被维持.因此,它为邻居维护了一张重传表.该表指示还没有被邻居确认的数据包.未确认的可靠数据包最多可以被重传1 6次或直到保持时间超时,以它们当中时间更长的那个为限.EIGRP所使用的多目组播地址是224.0.0.10Diffusing Update Algorithm(DUAL)EIGRP使用DUAL来选择和保持到远端的最佳路径.它能使router 判决某邻居通告的一个路径是否处于循环状态,并允许router找到替代路径而无须等待其他router的更新.这样做有助于加快网络的汇聚.这个算法顾及以下几点: 1.备份的路由线路 2.支持VL ___ 3.动态路由恢复 4.没有发现线路的话发送查询寻找新路线Using EIGRP to Support Large NetworksEIGRP在大型网络中能够工作的很好,包含了很多优点比如: 1.在1个单独的router上可以支持多个AS 2.支持VL ___和sum ___rization 3.路由发现和保持Multiple AS只有AS号相同的router才能共享路由信息.把大型网络分成不同的AS,可以有效的加快汇聚.EIGRP的AD为90,而外部EIGRP(external EIGRP)的AD为170VL ___ Support and Sum ___rization之前说过EIGRP支持VL ___,也支持不连续子网.什么是不连续子网?,如下图:如图可以看到,2个子网172.16.10.0/24和172.16.20.0/24由10.3.1.0/24来连接,但是routerA和B认为它们只有网络172.16.0.0EIGRP支持在任何运行EIGRP的router上sum ___ry的手动创建,这样可以减少路由表的体积.EIGRP自动把网络sum ___rize到等级边界,如下图:Route Discovery and Maintenan ___ 类似一些链路状态的协议,EIGRP通过Hello信息来发现邻居;而它又和距离向量类似,使用传闻路由的机制,即不主动去发现,而是听从别人的信息.EIGRP使用一系列的表来存储信息: 1.邻居表,记录了邻居的一些信息 2.拓扑表,记录了网络中的拓扑状态 3.路由表,根据这个来做路由决定EIGRP MetricsEIGRP使用混合度,包含到4个方面: 1.带宽 2.延迟(delay) 3.负载(load) 4.可靠性(reliability) 5.最大传输单元( ___ximum tran ___ission unix,MTU)默认情况下EIGRP使用带宽和延迟来决定最佳路径Configuration EIGRP配置EIGRP,首先在全局配置模式下使用router eigrp [AS号]命令.接下来再使用work命令定义直接相连的网络.仍然可以像配置IGRP那样使用passive-inte ___ ___命令来禁止某个接口接收或发送Hello信息.并且记住EIGRP的AD是90来看1个配置实例,如图:Router Network Address Inte ___ ___ Address RouterA192.168.10.0 fa0/0 192.168.10.1 192.168.20.0 s0/0192.168.20.1 RouterB 192.168.20.0 s0/0 192.168.20.2 192.168.40.0 s0/1 192.168.40.1 192.168.30.0 fa0/0 192.168.30.1 RouterC 192.168.40.0 s0/0 192.168.40.2 192.168.50.0 fa0/0 192.168.50.1 配置RouterA:RouterA(config)#router eigrp 10 RouterA(config-router)#work 192.168.10.0 RouterA(config-router)#work 192.168.20.0 RouterA(config-router)#^Z RouterA# 记住配置EIGRP和配置IGRP十分类似,唯一不同的是EIGRP是无分类路由(classless routing)配置RouterB: RouterB(config)#router eigrp 10RouterB(config-router)#work 192.168.20.0 RouterB(config-router)#work 192.168.30.0 RouterB(config-router)#work 192.168.40.0 RouterB(config-router)#^Z RouterB#配置RouterC: RouterC(config)#router eigrp 10RouterC(config-router)#work 192.168.40.0 RouterC(config-router)#work 192.168.50.0 RouterC(config-router)#^Z RouterC#这样配置看上去好象没什么问题,EIGRP的AD比之前配置的RIPv1和IGRP的低,但是有个问题就是:增加了CPU的负担,而且占用了额外的带宽还有1点要注意的是自动sum ___rization,router默认会向分级边界进行sum ___rize.如下图:A的配置如下: A(config)#router eigrp 100 A(config-router)#w 172.16.0.0 A(config-router)#w 10.0.0.0A(config-router)#no auto-sum ___ryB的配置如下: B(config)#router eigrp 100 B(config-router)#w 172.16.0.0 B(config-router)#w 10.0.0.0B(config-router)#no auto-sum ___ry 使用no auto-sum ___ry 命令后,运行了EIGRP的router就不会相互进行通告Verifying EIGRP在刚才配置好的情况下使用show ip route命令查看路由信息,如下: RouterA#sh ip route (略) D 192.168.30.0/24[90/2172416] via 192.168.20.2, 00:04:36, Serial0/0 (略) 注意字母D代表DUAL,即代表EIGRP,AD为90show ip route eigrp命令只显示路由表中的EIGRP选项show ip eigrp neighbors:显示所有的EIGRP邻居show ip eigrp topology:显示EIGRP拓扑表条目,如下: RouterC#sh ip eigrp topology (略) P 192.168.40.0/24, 1 suessors, FD is 21469856 Via Connected, Serial0 (略) 注意前面的P代表passive状态,这样的状态是正常的如果看见的是A即active状态而不是P,说明router失去了到这个网络的路径并且在寻找替代路径Open Shortest Path First(OSPF) Basics在1个大型网络中,假如不是所有的设备都是Cisco的,EIGRP明显就不行,因为它是私有的.所以就可以使用OSPF协议或者路由redistribution(路由协议之间的翻译服务).OSPF使用Dijkstra算法,是1种链路状态协议.OSPF汇聚快速,支持多个耗费相同的路径.和EIGRP不同的是,OSPF只支持IP路由.OSPF也能够设计网络为层次化的,这样就把1个大的网络分割成几个小的网络,叫做区域(area).这是OSPF最好的设计方法.把OSPF设计成层次化的好处是:1.减少路由成本(overhead)2.加速汇聚3.把大网络分割成小的区域下面是1个典型的OSPF设计图,如下:注意这个图,BR为骨干router(backbone router,BR),连接到这个骨干的为区域0或者骨干区域(backbone area),OSPF必须要有个区域0所有的router应该尽可能的连接到这个区域.连接其他区域到骨干区域的为区域边界router(area border router,ABR),ABR必须至少有1个接口位于区域0中.OSPF运行在1个AS中,而且能够连接多个AS,连接多个AS的router为自治系统边界router(autonomous system boundary router,ASBR)模板,内容仅供参考。

一种零中频数字接收机镜像抑制新算法

一种零中频数字接收机镜像抑制新算法区洋;刘重军;邓单【摘要】首先提出在零中频接收机中由于I/Q信号不平衡导致产生镜像干扰信号的数学模型,然后根据复随机信号的二阶统计特性,详细推导提出一种零中频数字接收机镜像抑制算法,并对算法实现的运算量进行合理的简化和分析,仿真结果表明:镜像抑制算法能够有效地抑制宽带信号和窄带信号在零中频接收机中产生的镜像信号,同时算法实现复杂度低.【期刊名称】《移动通信》【年(卷),期】2018(042)006【总页数】6页(P80-85)【关键词】零中频;I/Q不平衡;镜像抑制;循环平稳【作者】区洋;刘重军;邓单【作者单位】京信软件科技(广州)有限公司,广东广州 510663;京信通信技术(广州)有限公司,广东广州 510663;广州番禺职业技术学院,广东广州 510663【正文语种】中文【中图分类】TN929.51 引言在传统数字通信系统中，无线电射频（RF）信号进入接收端天线，通过下变频技术将射频信号转换为中频（IF）信号，再利用IQ解调技术将中频信号转换为I/Q相互正交的两路基带信号。

随着技术的发展，无论是用户还是运营商对终端接收设备体积的要求越来越高，因此零中频技术也随之产生。

零中频技术的基本思想是将RF信号直接变为基带信号，不经过中频的调制解调，从而取消中频滤波器，减小接收端设备的体积以及降低成本[1-4]。

图1给出零中频技术的原理框图，在零中频接收机中，一方面由于本地晶振与发射端晶振偏差，会造成基带信号相位与增益不平衡，即图1中虚线框中的φ与g，其中φ为相位偏差，g为增益偏差；另一方面，I/Q通路上的混频器（MIX）、低通滤波器（LPF）、可变增益放大器（PGA）以及ADC器件不一致也会造成I/Q信号不平衡，即图1中的传递函数hi与hq，分别表示I路和Q路信号的幅度特性。

这两方面的因素最终会导致I/Q基带信号不平衡，在以载波频点为中心对称的位置上产生一个镜像干扰信号，从而影响信号的解调性能，如图2所示：图1 零中频技术的原理框图图2 镜像信号干扰示意图对于零中频数字接收机，目前学者主要研究方向是对镜像干扰做有效地抑制。

CCNA(Stand-ALONE)Lab 27-Standard Access Lists Objective:Gain experience configuring standard access lists.Lab Equipment:Router 1, Router 2, and Router 4 from the eRo uters menuBackground Reading:Lab Primer Lesson 10: Access ListsIf you feel confident about configuring IP addresses and RIP, est ablish the configuration in the table below, and then continue wit h step 10.1. Connect to Router 1, assign it a host name of Router1, and s et the IP address on the Ethernet 0 interface to 24.17.2.1 255.2 55.255.240. Set the IP address on the serial 0 interface to 24.17.2.17 255.255.255.240. Remember to enable both interfaces.

Connect to Router 2, assign it a host name of Router2, and s et the IP address on the Ethernet 0 interface to 24.17.2.2 255.2 55.255.240. Remember to enable the interface.Router>enableRouter#config tRouter(config)#hostname Router2Router2(config)#interface ethernet0Router2(config-if)#ip address 24.17.2.2 255.255.255.240 Router2(config-if)#no shutdownRouter2(config-if)#exitRouter2(config)#exit3. From Router2, ping Router1’s Ethernet 0 interface to ens ure a connection exists.Router2#ping 24.17.2.14. Connect to Router 4, assign it a host name of Router4, and s et the IP address on the serial 0 interface to 24.17.2.18 255.255. 255.240. Then ping Router1’s serial 0 interface.Router>enableRouter#config tRouter(config)#hostname Router4Router4(config)#interface serial0Router4(config-if)#ip address 24.17.2.18 255.255.255.240Router4(config-if)#no shutdownRouter4(config-if)#exitRouter4(config)#exitRouter4#ping 24.17.2.175. Now that IP addresses have been configured on all interfaces, you need to implement a routing protocol to facilitate communica tion between Router2 and Router4. Enable Routing Information Pr otocol (RIP) on Router1, and add the network for Ethernet 0 and serial 0.Router1#config tRouter1(config)#router ripRouter1(config-router)#network 24.0.0.0Router1(config-router)#exitRouter1(config)#exit6. On Router2, enable RIP and add the network for Ethernet 0. Router2#conf tRouter2(config)#router ripRouter2(config-router)#network 24.0.0.0Router2(config-router)#exitRouter2(config)#exit7. On Router4, enable RIP and add the network for serial 0. Router4#conf tRouter4(config)#router ripRouter4(config-router)#network 24.0.0.0Router4(config-router)#exitRouter4(config)#exit8. Verify that you can ping Router2’s Ethernet 0 interface from R outer4.Router4#ping 24.17.2.29. Now, configure a standard access list to block Router4 from b eing able to ping Router2.You should configure this access list on Router2. First, connect to Router2 and enter global configuration mode.Router2#conf tRouter2(config)#10. Create access list 1 to block the single IP address 24.17.2.18. Here are three ways to accomplish this:Router2(config)#access-list 1 deny host 24.17.2.18ORRouter2(config)#access-list 1 deny 24.17.2.18 0.0.0.0ORRouter2(config)#access-list 1 deny 24.17.2.1811. Next, issue the access-list 1 permit any command.Router2(config)#access-list 1 permit any12. Now you need to apply the access list to the Ethernet 0 inter face. You must specify the direction of traffic flow upon which th e access list should apply. The in parameter configures the acces s list to apply to packets coming in from the network and traveli ng to the router. The out parameter configures the access list to apply to packets traveling from the router out the interface to th e network. In this scenario, you should use the in parameter.
