自愈技术,是提高通信网生存性的一种有效的手段,一旦通信系统发生故障,失效的链接将会靠网元之间互相传递自愈信息来寻找相应的迁回路由和自愈手段,而不是依靠网管中心区收集故障信息然后依据一定的优化准则再来调度的。自愈通信网的理论是通信工程研究的一个重要课题,其中提出的一些理论都是针对实际组网做出来的。自愈通信网理论的建立,提出了一些相关的理论。在自愈结构方面,有基于跨距(SPAN)间保护模式和基于通道(PATH)的保护模式这两种网络保护结构;在资源利用方面,有1+1的保护方式、1:1的保护方式、1:n和n:m的保护方式等等。
Self-healing technology is an effective way to improve the survivability of communication networks. Once a communication system fails, the failed links will find their corresponding rerouting routes and self-healing means by transmitting self-healing information to each other. Instead of relying on network management center to collect fault information and then re-scheduling according to certain optimization criteria. The theory of self-healing communication network is an important issue in the research of communication engineering. Some of the theories put forward are all based on the actual networking. The establishment of self-healing communication network theory, put forward some related theories. In terms of self-healing structure, there are two types of network protection structures, SPAN-based protection mode and PATH-based protection mode. In resource utilization, there are 1 + 1 protection mode and 1: 1 protection mode Way, 1: n and n: m protection methods and so on.
