Description

网元设备管理信息传送方法及装置和网元设备 NE device management information transmitting method and apparatus and a network equipment element

技术领域 FIELD

本发明涉及由同步数字体系(Synchronous Digital Hierarchy,SDH)或同步光纤网(Synchronous Optical Network,SONET)设备组成的传输网络,尤其涉及SDH或SONET网元设备的管理信息传送方法,以及相对应的网元设备管理信息传送装置和包含该传送装置的网元设备。 The present invention relates to a transmission network of the synchronous digital hierarchy (Synchronous Digital Hierarchy, SDH) or synchronous optical network (Synchronous Optical Network, SONET) device consisting, in particular, to the management information transmitting method SDH or SONET network element devices, and the network corresponding element device management information transfer apparatus and the conveying apparatus comprises a network element device.

背景技术 Background technique

一般来说,由SDH或SONET设备组成的传输网络都比较庞大,而网络一般都需要通过很少几个网管系统进行集中管理,对于直接与网管系统相连的网关网元可以通过设备的管理接口直接管理,但是对于不能直接与网管系统相连的非网关网元,传统的SDH与SONET传输设备都是通过其开销字节(D1~D12字节)来传递管理信息的,这些开销字节组成了数据通信通路(DataCommunications Channel,DCC),这种管理方式因与业务无关、甚至不需要任何配置等优点而得到了最广泛的应用,目前的SDH与SONET传输网络的管理信息传递大部分采用的是这种DCC通道方式。 Generally, the SDH or SONET transmission network consisting of devices are relatively large, and the network generally requires very few centrally managed through a network management system, to the gateway network element directly connected to the NMS directly through the management interface device managing, but not for the non-gateway NEs directly connected to the network management system, the conventional SDH transmission device is a SONET management information to pass through its overhead bytes (D1 ~ D12 bytes), the data overhead bytes a communication passage (DataCommunications Channel, DCC), regardless of the result of this management service, or even no configuration is required to obtain the advantages of the most widely used, the current SDH and SONET transmission management information transmission network which is used in most DCC kinds of channel mode.

DCC通道方式的工作原理如图1所示:在网络上设定网关网元(图1中网元C)后,网关网元与网管系统直接相连,而网络上所有的其它非网关网元(图中网元A、B、D、E、F)都通过网关网元与网管系统通信。 DCC channel works embodiment shown in Figure 1: after setting the gateway network element (NE in Fig. 1 C) on the network, the gateway network element directly connected to the network management system, network and all other non-GNE ( FIG network element A, B, D, E, F) are in communication with the network management system via membered GNE. 网关网元与非网关网元之间是通过线路SDH/SONET开销(D1~D12字节)相互通信的。 GNE GNE and between the non-line via SDH / SONET overhead (D1 ~ D12 bytes) communicate with each other. 这种通过DCC通道管理网元的方法有两个比较大的缺点:(1)、DCC通道的带宽小而且固定不变,最大为768Kbps,在网元管理中,软件升级是一种常用的维护手段,在当前的传输设备上业务不断发展丰富,网元内各个单元的软件规模也在逐渐增大,所以通过DCC通道加载升级网元软件的时间也在不断加长,这样势必较大地浪费维护人力;(2)、DCC通道依赖于线路SDH/SONET开销,而这种开销不能被另一个厂家传输设备透传,也不能互通,所以当一个厂家的传输设备被另一个厂家的传输网络所分隔时,那么被分隔的传输设备将无法通过同一个网管集中管理。 This method has by DCC channel management element of a relatively large two drawbacks: (1), the low-bandwidth channel DCC and fixed, a maximum of 768Kbps, the management NE, the software upgrade is a common maintenance means, in the current transmission equipment business continues to develop rich, software size of each unit within the NE is gradually increased, the load time NE software upgrade through DCC channel has also been extended, this is bound to maintain a large waste of manpower ; (2), DCC channel dependent on line SDH / SONET overhead, and this overhead can not be transmitted to another device passthrough manufacturers, we can not communicate, when the manufacturers of the transmission device are separated by other manufacturers transmission network then separated by transmission equipment will not be centrally managed through the same network.

因此,随着以太网、异步传输模式(Asynchronous Transfer Mode,ATM)等多种业务融入到SDH与SONET设备,网元的配置量及软件规模都在不断的增大,DCC通道的带宽已经明显成为网元管理维护的瓶颈,从而导致对远程非网关网元的管理效率非常低,所以,从长远发展来看,通过DCC通道管理SDH与SONET设备的方法已经无法满足日常管理维护的需要。 Therefore, as Ethernet, ATM (Asynchronous Transfer Mode, ATM) and other services into SDH and SONET equipment, network element configuration and the amount of software size are constantly increasing bandwidth DCC channel has become evident NE maintenance management bottlenecks, resulting in efficient management of remote non-gateway NE is very low, so the long-term development, channel management by DCC method SDH and SONET equipment has been unable to meet the needs of daily management and maintenance. 另外,由于SDH与SONET传输设备的发展,多个厂家设备联合组网的情况已经成为一种普遍现象,但是由于不同厂家的DCC通道一般不能互通,而且一个厂家设备不能透传另外一个厂家设备的DCC通信,所以对于比较分散却不能通过线路光纤直连厂家设备的管理就比较困难,目前解决这个问题的方法是通过数字数据网(Digital Data Network,DDN)对网元进行管理。 Further, since the development of SDH and SONET transmission apparatus, a plurality of network equipment manufacturers joint has become a universal phenomenon, but since the DCC channel of different manufacturers generally can not communicate, but not transparently transmit a manufacturer other equipment manufacturers DCC communication method, but not so for scattered through the line optical fiber directly connected to the management equipment manufacturers difficult to solve this problem at present is managed by the NE digital data network (digital data network, DDN).

DDN管理网元的具体方法如图2所示,包括:将网元管理接口通过数据设备(如路由器)连接到网元的可以与数据设备互通的接口上。 The specific method DDN management element shown in Figure 2, comprising: an interface connected to the management NE NE may communicate with the data device via the data interface devices (such as routers). 例如,图2中网元A、B、C、D的网元管理接口都通过数据设备连接到网元的准同步数字体系(Plesiochronous Dieital Hierarchy,PDH)接口,然后配置一条相应的业务通道穿过另一个厂家的传输网络传送管理信息,当传送的管理信息到达与网管系统相连接的网关网元后,通过该网关网元的PDH接口传送管理信息到连接的数据设备,再通过数据设备连接到网管系统进行管理。 For example, in Figure 2 the network element A, B, C, D of the network element management interface is connected to the device via the data network element plesiochronous digital hierarchy (Plesiochronous Dieital Hierarchy, PDH) interfaces, and configure a passage through the corresponding service another manufacturer transfer management information transmission network, when the management information is transmitted to the gateway network element and the network management system connected to the data device connected, and then connected to the GNE through the PDH interface apparatus via the data transfer management information network management system to manage.

通过DDN对传输网元进行集中管理的方法有如下缺点:(1)、网元管理必须借助于额外的数据设备(如路由器),这样成本比较高,稳定性也难以控制,因为它依赖于网元自身及数据设备的稳定性;(2)、需要占用网元设备额外的接口,对网元的接口是一种浪费; The method has the following drawbacks by DDN transmission NEs centralized management: (1), by means of a network element management must additional data devices (such as routers), so the cost is relatively high and the stability is difficult to control because it depends on network stability data of itself and the device; (2), take up additional network element interface device, the interface of the network element is a waste;

(3)、一般来说,管理带宽比较小且固定不可变,如通过PDH接口传递管理信息,那么管理带宽只能是PDH端口所能提供的速率,如2Mbps等。 (3), in general, to manage bandwidth and relatively small fixed immutable, such as through PDH interfaces to transfer management information, the management of bandwidth only is the rate of PDH port can deliver, and the like as 2Mbps.

如果网元设备本地有管理信息需要传送到网管系统,则根据该网元设备是否直接与网管系统相连接,又分为如下两种情况:(1)、网元设备为网关网元,其以太网接口直接连接到网管系统;在这种情况下,本地网元设备产生的管理信息由网元设备管理模块通过本地网元以太网处理模块交换处理后直接发送到网管系统。 If the local network element device management information needs to be transmitted to the network management system, based on whether the network element devices are connected directly to the network management system is divided into the following two situations: (1), the gateway device is a network element NE, which Ether network interface connects directly to the network management system; in this case, information of the local network element management device generates the Ethernet local network element after the processing module directly transmits to the exchange process by the network management system NE device management module.

(2)如果网元设备没有直接与网管系统相连接,本地产生的管理信息需要先传送到与网管系统相连接的网关网元(可能需要经过一个或多个中间穿通网元的传递);在这种情况下,本地网元设备产生的管理信息,需要经过以下处理过程:步骤1、网元设备管理模块先将本地网元设备产生的管理信息封装成以太网数据包;步骤2、再将以太网数据包采用EOS封装协议,如:采用GFP、LAPS、HDLC等协议进行再封装;步骤3、将再封装后的数据包映射到配置的虚通道,由本地网元设备的SDH/SONET线路模块通过SDH/SONET线路占用业务通道发送到下一个网元设备的SDH/SONET线路模块;步骤4、下一个网元设备的SDH/SONET线路模块接收到携带管理信息的数据包后传送到本地网元设备内部的交叉连接模块;交叉连接模块根据预先配置的交叉连接,将接收的携带管理信息的数据包交换到相 (2) If the NE device is not connected directly to the network management system, the management information generated locally need to be transmitted to the gateway network element (possibly through a network element is transmitted through one or more intermediate) and the network management system is connected; in in this case, the management information generated by the local network element device, need to go through the following process: step 1, the management information NE device management module first local network device generates the element encapsulated into Ethernet packets; step 2, and then Ethernet packets using EOS encapsulation protocol, such as: use of GFP, LAPS, HDLC protocol resealing the like; after the step 3, we will go into the packet encapsulation mapping the virtual channel configuration, a local network element equipment SDH / SONET line module sent through SDH / SONET transmission-line service channel to the SDH next network element device / SONET line modules; step 4, SDH next network element device / SONET line module receives a data package management information is transmitted to the local network metadevice internal cross-connect module; cross-connect cross-connect module according to pre-configured management information carried in the data packet is switched to the phase of the received 的与下一个网元设备相连的SDH/SONET线路模块,并由此SDH/SONET线路模块的SDH/SONET线路接口传送到下一个网元设备;步骤5、重复步骤4,直到传送的携带管理信息的数据包到达与网管系统相连接的网关网元;步骤6、网关网元设备对虚通道中的携带管理信息的数据包解映射;再将所述携带管理信息的数据包采用EOS解封装协议解封装;并将解封装后的以太网数据包通过以太网接口发送到网管系统。 SDH / SONET line modules are connected to the next network element devices, and thereby SDH / SONET line modules SDH / SONET line interface is transferred to the next network element device; Step 5, Step 4 is repeated until a carry management information transfer the packet arrives at the gateway network element and the network management system is connected; step 6, the gateway NE device management information data carried in the packet virtual channel demapping; then the packet carrying the data management information using EOS protocol decapsulation decapsulating; decapsulated Ethernet and the Ethernet interface to send packets to the network management system through.

以上方法步骤中,映射到虚通道时对应的映射颗粒可以在设计网元设备时确定,如采用VC12/VC3/VC4/VT1.5/STS-1/STS-3c等。 The above process steps, the corresponding mapping to a virtual channel mapping particles may be determined in the design of the network element devices, such as the use VC12 / VC3 / VC4 / VT1.5 / STS-1 / STS-3c and the like. 当网元设备的映射颗粒确定后,为了灵活控制传输带宽,可以采用级联或虚级联方式扩大传送管理信息的虚通道带宽。 When the network element mapping device to determine the particle, for flexible control of the transmission bandwidth, it can be cascaded to expand or virtual concatenation mode virtual channel bandwidth carrying management information.
