Description

基于复杂包交换***的分布式SSM协议处理***及方法Distributed SSM protocol processing system and method based on complex packet switching system 技术领域Technical field
本发明涉及同步传输***技术领域，具体来讲是一种基于复杂包交换***的分布式SSM(Synchronous Status Message，同步状态消息)协议处理***及方法。The present invention relates to the field of synchronous transmission systems, and in particular to a distributed SSM (Synchronous Status Message) protocol processing system and method based on a complex packet switching system.
背景技术Background technique
目前，SSM协议广泛用于传输领域的同步数字***中。对于同步***，时钟的同步是至关重要的，而在同步***的时钟拓扑设计中避免定时环是设计的首要考虑目标。Currently, the SSM protocol is widely used in synchronous digital systems in the transmission field. For synchronous systems, clock synchronization is critical, and avoiding timing loops in the clock topology design of synchronous systems is a primary consideration for design.
对于如何避免产生定时环，SSM协议的实现是一个重要的手段。SSM协议的实现不仅包括SSM规则的实现，对SSM信息处理的时间也有严格的要求。按照G.8262和国标YD/T 1267要求，无切换条件下的SSM处理延时TNSM(非倒换信息时延)<200ms，有切换条件下的SSM处理延时TSM(倒换信息时延)<500ms，保持条件下的SSM处理延时THM(保持信息时延)<2000ms。The implementation of the SSM protocol is an important means for avoiding the generation of timing loops. The implementation of the SSM protocol includes not only the implementation of the SSM rules, but also the strict processing requirements for the SSM information processing time. According to G.8262 and national standard YD/T 1267, SSM processing delay T NSM (non-switching information delay) <200ms without switching conditions, SSM processing delay T SM under switching conditions (switching information delay) <500ms, SSM processing delay T HM (holding information delay) <2000ms under holding conditions.
随着当前通讯设备越来越复杂，支持的业务处理端口也逐渐增多。每个端口都需要支持时钟同步，支持传递SSM信息。假设共有N块业务盘，每块业务盘有M个端口。按照传统的算法，主控CPU共需进行N*M个端口的SSM信息运算。对于复杂***，SSM协议栈的处理端口可能非常多。此时***本身所需处理的业务数量大，业务种类复杂，主控盘上CPU负载很大，同时处理多端口的SSM消息，SSM延时将不满足协议要求。如果SSM协议的处理时延过大，当时钟源 发生切换时将使时钟环路中产生定时环(定时环：从钟跟踪到自己提供的网同步信号的现象，称为定时环。当从钟输出直接或经过网络间接环回到输入时，发生定时环)，导致整体时钟链路不稳定，并在时钟链路中产生振荡。As current communication devices become more complex, the number of supported service processing ports is increasing. Each port needs to support clock synchronization and support the delivery of SSM information. Assume that there are a total of N service disks, each of which has M ports. According to the traditional algorithm, the master CPU needs to perform SSM information operations on N*M ports. For complex systems, the processing port of the SSM stack can be very large. At this time, the number of services to be processed by the system itself is large, the types of services are complex, and the CPU load on the main control disk is large. At the same time, multi-port SSM messages are processed, and the SSM delay will not meet the protocol requirements. If the processing delay of the SSM protocol is too large, when the clock source When a switch occurs, a timing loop is generated in the clock loop (timing loop: the phenomenon of tracking from the clock to the network synchronization signal provided by itself, called the timing loop. When the clock output is directly or through the network indirectly loop back to the input, it occurs. The timing loop) causes the overall clock link to be unstable and oscillates in the clock link.
