Actual distance depends on network physical characteristics.InstallationDescriptionThe N‐FX module has bootable ROM and Wake‐On LAN capabilities. The two LED indicators, LINK/ACT and FDX, located on the bracket, show network/board link, activities, collision, and full‐duplex statuses. See Figure 1 below.Figure 1: LEDs and Wake‐On LAN ConnectorInstallation ProcedureCAUTION: Wear a grounding strap and observe electrostatic discharge precautions when installing the N‐FX module. Failure to observe this caution could result in damage or failure of the N‐FX module. Perform the steps below to install the NIC. Important: Install the N‐FX NIC in a “master slot” only.1.Select one of the two options for WoL to match the host PC’s capabilities:a.via WoL 3‐pin connector (Fig. 1 above), orb.via PCI bus; see Wake‐on‐LAN (WoL) on page 6.2.Locate a master slot on the PC workstation or file server.3.Remove the cover from the PC workstation or file server ‐ keep all screws.4.Remove and keep the screws holding the cover to the installation slot.5.Carefully align the module to the slot guides and slide it into the “master slot.”6.Ensure that the module is firmly seated in the slot.e the screws saved in Step 4 above to secure the module to the workstation or file serverhousing.ConfigurationFor motherboards with automatic PCI configuration:∙No specific setup is needed. (You can enter the system BIOS setup menu to view or specify the interrupt (INT) line of the PCI slots.)For motherboards with bus master and interrupt jumpers:∙Enable bus master operation in a selected PCI slot and select an INT request line (IRQ) level, using the appropriate motherboard jumper.∙Enable I/O on the N‐FX, PCI slot.PCI Bus System and Configuration∙Ensure that the PCI machine supports master slots, INT multiple sharing, and timing compatibility.∙DO NOT install N‐FX in PCI slave slots. Please refer to your PC system manual and select the appropriate configuration settings.∙When installing multiple N‐FX modules in a server station, you can correctly configure the IRQ settings of the PCI slot.∙Up to four N‐FX modules can be installed in a PCI file server, running a NetWare operating system.∙N‐FX server modules share the same INT line with the driver supporting multiple INT services ata time. The IRQ of each N‐FX module should not conflict with other boards.∙Operation in full duplex (default) or half‐duplex mode is configured by LAN driver options.The operating mode should match the working status of the remote link device.∙Use EMM386 version 4.49 or higher, and install both DOS and EMM386 from the same DOS package to avoid software problems.Booting the SystemThe NIC can boot according to PXE (default) or RPL protocols. If you want to boot from BIOS you mustre‐configure the NIC according to BIOS settings.Boot OptionsThe NIC is capable of the following boot modes:Local Only: In this mode, network boot is disabled on the NIC. This option is useful for conserving Option ROM space or ensuring the network boot will not occur through this NIC.According to BIOS: In this mode, the NIC will follow the BIOS configuration for network boot. This option can be used when the user wants the host process to be controlled entirely by the BIOS.Network first, then Local (default): In this mode, the NIC takes over the boot process regardless of the BIOS boot configuration and the NIC attempts to force the PC to boot through its own network interface. If the network boot fails, the PC diverts back to booting according to the boot order configured in the BIOS. This mode is useful for enabling network boot on PCs that do not have network boot options in the BIOS.Local first, then Network: In this mode, the NIC allows booting according to the BIOS boot order configuration. If booting according to the BIOS boot order fails, the NIC attempts to force booting through its own network interface.To Change Boot Options1.At start‐up, a prompt displays to Press <Shift> + <Tab> key to display boot option menu.2.Press Shift and Tab keys together at the prompt. A screen displays with the NIC boot options:3.Change the Boot Option setting to the desired option.4.Save and exit.Wake-on-LAN (WoL)This section outlines the methods for configuring WOL based on the type of PCI bus in the PC.Wake‐on‐LAN is implemented using a special network message called a magic packet. The magic packet contains the MAC address of the destination computer. The listening computer waits for a magic packet addressed to it and then initiates system wake‐up. The magic packet is sent on the data link (OSI Layer 2) and is broadcast to all NICs using the network broadcast address (the IP‐address is not used).The Technical Specifications section of this manual shows:Wake‐ON‐LAN supports magic packets only:∙PCI 2.1 implemented via the 3‐PIN WOL connector (WOL cable needed)∙PCI 2.2 implemented directly via PME# signal (no WOL cable needed)Note that PCI 2.2 does not use the WOL cable; the WOL function is done via the PCI slot.For PCI 2.1, these slots do require the use of a WOL cable, and you are installing the N‐FX‐xx‐03 in a PCI 2.1 slot and you want to use the WOL feature, use the provided WOL cable The WOL cable TN part number is 4100 (included with the N‐FX‐xx‐03).Most versions of Microsoft Windows integrate WoL functionality into the Device Manager, available in the Power Management tab of each network device. Often, the correct BIOS configuration is also required for WoL to function. In Windows Vista and higher, you can determine how the OS was powered up by running the powercfg / lastwake command in a CMD prompt to list the "Wake Source". The WoL event should also be logged in the System Event log. In Linux, WoL may be changed with a subfunction of the ethtool command.LED FunctionsThe LED is a single green color.LED DescriptionFDX ON Full duplex.

PSI表

DVB业务信息PSI/SI介绍一、SI信息的构成1、信息构成SI信息内容是按照network 网络)→transport strem（传输流）→service（业务）→event（事件）的分层顺序描述，如图1所示。

SI数据信息是按照一定的数据结构进行存储的，这样一来才能达到方便、快捷地进行数据检索和提取。

SI数据主要有：网络信息、传输流信息、业务信息、业务的事件信息等，并且大量的信息都是通过描述符来传输的，所以可用树状链表来存储数据，构成从网络、传输流、业务、事件的树状结构。

机顶盒接收端的解析主要负责这些SI数据的重建。

在数字电视系统中，为了能有效地从众多的数据包中组织起SI信息，而使用了很多的标识。

有Network_id 网络标识)、Original_network_id 原始网络标识)、Transport_stream_id 传输流标识)、Service id 业务标识)、eventid_id 事件标识)、Bouquet_id 业务群组标识)。

这些标识是作为信息查找定位用的，例如：要在一个TS里找出一个业务信息，就要知道这个业务信息在那个网络里、在哪个TS里和这个业务信息在这个流里的标识，这样一来，通过层层过滤，就能精确地定位描述这个业务信息的位置，并把它们找出来进行数据组织。

图1就非常清楚地表明了这种查找思路。

一个网络信息由network_id来定位。

一个TS由network_id、Original_network_id、Transport_stream_id来定位，标明这个流在那个网络播发，它原属那个网络，并给它加上标识。

一个业务由network_id、Original_network_id、Transport_stream_id、service_id来定位，标明这个业务在那个网络播发，它原属那个网络和那个流，并给它加上标识。

这体现在SDT表中。

一个事件由network_id、Original_network_id、Transport_stream_id、service_id、event_id来定位，标明这个事件在那个网络播发，它原属那个网络和那个流及那个业务，并给它加上标识。

Symphony Enterprise Management和控制系统的Cnet高速数据通信网络说明

Features and Benefits Overview Control ITHarmony RackCommunications Control Network, Cnet, is a high-speed data communicationhighway between nodes in the Symphony™ Enterprise Man-agement and Control System. Cnet provides a data pathamong Harmony control units (HCU), human system inter-faces (HSI), and computers. High system reliability andavailability are key characteristics of this mission-criticalcommunication network. Reliability is bolstered by redun-dant hardware and communication media in a way that thebackup automatically takes over in the event of a fault in theprimary. Extensive use of error checking and messageacknowledgment assures accurate communication of criticalprocess data.Cnet uses exception reporting to increase the effective band-width of the communication network. This method offers theuser the flexibility of managing the flow of process data andultimately the process. Data is transmitted only when it haschanged by an amount which can be user selected, or when apredetermined time-out period is exceeded. The system pro-vides default values for these parameters, but the user cancustomize them to meet the specific needs of the processunder control.TC00895A■Fast plant-wide communication network: Cnet provides fastresponse time to insure timelyinformation exchange.■Efficient data transfer: Message packing and multiple address-ing increase data handlingefficiency and throughput.■Plant-wide time synchronization: Time synchronization of Cnetnodes throughout the entirecontrol process insures accuratedata time-stamping.■Independent node communica-tion: Each Cnet node operatesindependently of other nodes.Requires no traffic directors;each node is its owncommunication manager.■Accurate data exchange: Multi-ple self-check features including positive message acknowledg-ment, cyclic redundancy checks(CRC), and checksums insuredata integrity.■Automatic communications recovery: Rack communicationmodules provide localized start-up/shutdown on power failurewithout operator intervention.Each type of interface supportsredundancy.Harmony Rack CommunicationsOverviewHarmony rack communications encompasses various communication interfaces as shown inFigure1: Cnet-to-Cnet communication, Cnet-to-HCU communication, and Cnet-to-computercommunication.Figure 1. Harmony Rack Communications ArchitectureThe communication interface units transfer exception reports and system data, control, and con-figuration messages over Cnet. Exception reported data appears as dynamic values, alarms, and state changes on displays and in reports generated by human system interfaces and other system nodes. Exception reporting is automatic at the Harmony controller level. Specifically, the control-ler generates an exception report periodically to update data, after a process point reaches adefined alarm limit or changes state, or after a significant change in value occurs.Harmony Rack Communications Control NetworkCnet is a unidirectional, high speed serial data network that operates at a 10-megahertz or two-megahertz communication rate. It supports a central network with up to 250 system node connec-tions. Multiple satellite networks can link to the central network. Each satellite network supports up to 250 system node connections. Interfacing a maximum number of satellite networks gives a system capacity of over 62,000 nodes.On the central network, a node can be a bridge to a satellite network, a Harmony control unit, a human system interface, or a computer, each connected through a Cnet communication interface.On a satellite network, a node can be a bridge to the central network, a Harmony control unit, a human system interface, or a computer.Harmony Control UnitThe Harmony control unit is the fundamental control node of the Symphony system. It connects to Cnet through a Cnet-to-HCU interface. The HCU cabinet contains the Harmony controllers and input/output devices. The actual process control and management takes place at this level. HCU connection to Cnet enables Harmony controllers to:■Communicate field input values and states for process monitoring and control.■Communicate configuration parameters that determine the operation of functions such asalarming, trending, and logging on a human system interface.■Receive control instructions from a human system interface to adjust process field outputs.■Provide feedback to plant personnel of actual output changes.Human System InterfaceA human system interface such as a Signature Series workstation running Maestro or ConductorSeries software provides the ability to monitor and control plant operations from a single point. It connects to Cnet through a Cnet-to-computer interface. The number of workstations in a Sym-phony system varies and depends on the overall control plan and size of a plant. The workstation connection to Cnet gives plant personnel access to dynamic plant-wide process information, and enables monitoring, tuning, and control of an entire plant process from workstation color graphics displays and a pushbutton keyboard.ComputerA computer can access Cnet for data acquisition, system configuration, and process control. It con-nects to Cnet through a Cnet-to-computer interface. The computer connection to Cnet enablesplant personnel, for example, to develop and maintain control configurations, manage the system database, and create HSI displays remotely using Composer™engineering tools. There are addi-tional Composer and Performer series tools and applications that can access plant informationthrough a Cnet-to-computer interface.Cnet-to-Cnet Communication InterfaceThe Cnet-to-Cnet interfaces are the INIIR01 Remote Interface and the INIIL02 Local Interface.Figure2 shows the remote interface and Figure 3 shows the local interface.Harmony Rack CommunicationsFigure 2. Cnet-to-Cnet Remote Interface (INIIR01)Figure 3. Cnet-to-Cnet Local Interface (INIIL02)Harmony Rack Communications INIIR01 Remote InterfaceThe INIIR01 Remote Interface consists of the INNIS01 Network Interface Module and the INIIT12 Remote Transfer Module (Fig.2). This interface is a node on a central network that can communi-cate to an interface node on a remote satellite network. In this arrangement, two interfaces arerequired: one for the central network, and the other for the satellite network. Bidirectional commu-nication from the central network to the remote satellite network is through standard RS-232-Cports.The remote interface supports hardware redundancy. Redundancy requires a full set of duplicate modules (two INNIS01 modules and two INIIT12 modules on each network). The secondaryINIIT12 module continuously monitors the primary over dedicated Controlway. A failover occurs when the secondary module detects a primary module failure. When this happens, the secondary interface takes over and the primary interface is taken offline.INIIL02 Local InterfaceThe INIIL02 Local Interface consists of two INNIS01 Network Interface modules and the INIIT03 Local Transfer Module (Fig.3). This interface acts as a bridge between two local Cnets. One of the INNIS01 modules operates on the central network side and the other operates on the satellite net-work side. Bidirectional communication from the central network to the local satellite network is through cable connection to the NTCL01 termination unit. The maximum distance betweentermination units on the two communication networks is 45.8 meters (150feet).The local interface supports hardware redundancy. Redundancy requires a full set of duplicatemodules (four INNIS01 modules and two INIIT03 modules). The secondary INIIT03 module con-tinuously monitors the primary over dedicated Controlway. A failover occurs when the secondary detects a primary module failure. When this happens, the secondary assumes responsibility and the primary is taken offline.Cnet-to-HCU Communication InterfaceThe Harmony control unit interface consists of the INNIS01 Network Interface Module and the INNPM12 or INNPM11 Network Processing Module (Fig. 4). This interface can be used for a node on the central network or on a satellite network (Fig.1). Through this interface the Harmony con-trol unit has access to Cnet and to Controlway at the same time. Controlway is an internal cabinet communication bus between Harmony rack controllers and the communication interfacemodules.The HCU interface supports hardware redundancy. Redundancy requires a full set of duplicate modules (two INNIS01 modules and two INNPM12 or INNPM11 modules). The secondary net-work processing module (INNPM12 or INNPM11) continuously monitors the primary through a direct ribbon cable connection. A failover occurs when the secondary detects a primary module failure. When this happens, the secondary assumes responsibility and the primary is taken offline. Cnet-to-Computer Communication InterfaceThe Cnet-to-computer interfaces are the INICI03 and INICI12 interfaces. The INICI03 interfaceconsists of the INNIS01 Network Interface Module, the INICT03A Computer Transfer Module,and the IMMPI01 Multifunction Processor Interface Module (Fig. 5). The INICI12 interface con-sists of the INNIS01 Network Interface Module and the INICT12 Computer Transfer Module(Fig6).Harmony Rack CommunicationsFigure 4. Cnet-to-HCU InterfaceFigure 5. Cnet-to-Computer Interface (INICI03)Figure 6. Cnet-to-Computer Interface (INICI12)Harmony Rack CommunicationsA computer interface can be used for a node on the central network or on a satellite network (Fig.1). It gives a host computer access to point data over Cnet. The computer connects through either an RS-232-C serial link at rates up to 19.2 kilobaud or through a SCSI parallel port when using an INICI03 interface. The computer connects through an RS-232-C serial link at rates up to 19.2 kilobaud when using an INICI12 interface. Each interface is command driven through soft-ware on the host computer. It receives a command from the host computer, executes it, then replies to the host computer.Note: A workstation running Conductor VMS software does not use an INICI03 or INICI12 Cnet-to-Computer Interface but instead has its own dedicated version of the Cnet-to-computer interface (IIMCP02 and IIMLM01).Communication ModulesTable 1 lists the available Harmony rack communication modules. These modules, in certain combinations, create the various Cnet communication interfaces.Network Interface ModuleThe INNIS01 Network Interface Module is the front end for all the different Cnet communication interfaces. It is the intelligent link between a node and Cnet. The INNIS01 module works in con-junction with the transfer modules and the network processing module. This allows any node to communicate with any other node within the Symphony system.The INNIS01 module is a single printed circuit board that occupies one slot in the module mount-ing unit (MMU). The circuit board contains microprocessor based communication circuitry that enables it to directly communicate with the transfer modules and network processing module, and to interface to Cnet.The INNIS01 module connects to its Cnet communication network through a cable connected to an NTCL01 termination unit. Communication between nodes is through coaxial or twinaxial cables that connect to the termination units on each node.Cnet-to-Cnet Remote Transfer ModuleThe INIIT12 Remote Transfer Module supports bidirectional communication through twoRS-232-C ports. Port one passes system data only. Port two passes system data or can be used as a diagnostic port. The central network INIIT12 module can use a variety of means to link to the sat-ellite network INIIT12 module such as modems, microwave, and transceivers. The INIIT12Table 1.

Modular Power System II supplies the logic power. These operating voltages are distributed from thepower system through a system power bus bar mounted in the cabinet. A module mounting unit connects to this bus bar then routes the power to individual modules through backplaneconnectors.Rack Communications Mounting HardwareHarmony rack communication modules and their termination units mount in standard ABB cabi-nets. The option for small cabinet mounting is provided. The number of modules that can bemounted in a single cabinet varies. Modules of an interface are always mounted in adjacent slots.An IEMMU11, IEMMU12, IEMMU21, or IEMMU22 Module Mounting Unit and an NFTP01 Field Termination Panel are used for module and termination unit mounting respectively (Fig. 7). The mounting unit and termination panel both attach to standard 483-millimeter (19-inch) width side rails. Front mount and rear mount MMU versions are available to provide flexibility in cabinetmounting.A module mounting unit is required to mount and provide power to rack mounted modules. Theunit is for mounting Harmony rack controllers, I/O modules, and communication interfacemodules. The MMU backplane connects and routes:■Controlway.■I/O expander bus.■Logic power to rack modules.The Controlway and I/O expander bus are internal cabinet, communication buses. Communica-tion between rack controllers and HCU communication interface modules is over Controlway. The Cnet-to-Cnet interfaces use dedicated Controlway for redundancy communication. This dedicated Controlway is isolated from all other modules.Harmony Rack CommunicationsFigure 7.

Network的含义

Network的含义Network是在路由进程下的一条命令的其作用是：如果接口下配置了ip地址，那么被network 匹配到的接口就加入进了路由选择协议的进程中，那么这些接口就会发送hello包来建邻居，当然rip是没有hello包的，这个network的宣告可以只包含一个接口也可以包含几个接口还可以是一个或多个网段的接口，总之只要network宣告中包含的接口都会加入到这个进程中(前提是接口是打开的且有地址和掩码)，但network宣告并不影响路由条目的掩码位数，network宣告的不同只是包括的ip地址的范围的大小而已，network可以将路由表中直连的接口宣告进来，可以是打C的或者S的(静态路由写的是出接口而不是下一跳地址)格式：network + 网段或单个地址+反掩码子网掩码子网掩码：子网掩码(IP subnet mask)是用在接口下配置地址时用的，用连续的数个1开头的二进制位表示的，连续的1后面是连续的0，用于表示ip地址的掩码，如：1.1.1.1 255.255.255.0 其中255.255.255.0就是一个子网掩码，子网掩码也是32位的和ip地址其实是对应的，子网掩码的第一位对应ip地址的第一位，第二位对应第二位以此类推直到第32位，子网掩码的1表示它所对应的ip地址为网络位，0表示他所对应的ip地址为主机位，由于ip地址前面连续的是网络位而后面连续的是主机位，所以这就要求子网掩码前面必须是连续的1后面必须是连续的0，否则是不正确的且无法输入到路由器当中。

反掩码反掩码：之所以叫反掩码(wild card bits)是因为它的写法和子网掩码(IP subnet mask)是相反的子网掩码是连续的1开头后面是连续的0跟随，而反掩码是连续的0开头连续的1跟随。

0表示精确匹配network后面的网络号的二进制位1表示忽略不匹配network后面的网络号的二进制位比如进程下network 12.1.1.0 0.0.0.255网络号12.1.1.0 划为二进制是00001100 00000001 00000001 0000000反掩码0.0.0.255划为二进制是00000000 00000000 00000000 1111111通过上面的比较可以看出网络号的前24位被匹配到了，而因为反掩码的后8位为1，1表示忽略就是说只要有接口的ip地址的前24位为00001100 00000001 00000001 的ip地址都被宣告进了路由协议的进程中，那又因为12.1.1.1--12.1.1.254的ip地址的前24位都为00001100 00000001 00000001 所以只要是这些地址都被宣告进了路由协议的进程中其实就是network后面的反掩码跟network后面的网络号相比较(0就复制1就不进行比较)得出的结果，再跟network后面的反掩码与接口ip地址相比较得出的结果进行对比，相同就表明该接口宣告进了路由进程，不同就表示没有宣告进进程，network 0.0.0.0 0.0.0.0 这条命令除外，0.0.0.0 表示匹配所有在show run中会显示network 0.0.0.0如果写成network 0.0.0.0255.255.255.255 那么show run中显示的还是network 0.0.0.0,当在ospf的进程中输入network 0.0.0.0 0.0.0.0命令时路由器会自动翻译成0.0.0.0 255.255.255.255，因为0.0.0.0表示匹配所有，而255.255.255.255表示忽略那所以就是匹配了所有，而在eigrp 中显示的是network 0.0.0.0把所有接口都宣告进了路由进程中，如果写反掩码时写成连续的1开头连续的0跟随那么系统会自动把1转换成0，把0转换成1。

CentOS 7 单网卡多IP配置

CentOS 7 下的网络配置工具之前在CentOS 6下编辑网卡，直接使用setup工具就可以了。

但在新版的CentOS 7里，setuptool已经没有网络编辑组件了，取而代之的是NetworkManager Text User Interface，即nmtui。

nmtui默认随系统标准安装，如果你使用最小化安装，可能没有该软件，使用下面的命令手动安装：再次运行nmtui,即可看到网络编辑界面了，这里可以编辑连接、激活新网络连接和设置主机名字，根据实际需要选择即可：一、nmtui手工添加IP看一下当前网络设备的IP，为了精简指令输出，指令就要复杂一些了：view sourceprint?01.[root@centos7 ~]#nmcli -t -f IP4.ADDRESS dev show enp0s302.IP4.ADDRESS[1]:ip = 192.168.150.110/24, gw = 192.168.150.25403.[root@centos7 ~]#04.[root@centos7 ~]#ipaddr show enp0s3 scope global05.2: enp0s3: <BROADCAST,MULTICAST,UP,LOWER_UP>mtu 1500 qdiscpfifo_fast state UP qlen 100006.link/ether 08:00:27:15:35:d2 brdff:ff:ff:ff:ff:ff07.inet 192.168.150.110/24 brd 192.168.150.255 scope global enp0s308.valid_lft forever preferred_lft forever09.[root@centos7 ~]#10.[root@centos7 ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth011.......12.IPADDR0=192.168.150.11013.PREFIX0=2414.GATEWAY0=192.168.150.25415.DNS1=192.168.150.25416.HWADDR=08:00:27:15:35:D217.IPADDR1=192.168.150.11118.PREFIX1=2419.[root@centos7 ~]#新IP已经被加入到ifcfg-eth0中，原始地址的关键字是IPADDR0、PREFIX0，新地址的关键字是IPADDR1、PREFIX1 。
