通信传输系统的网络保护分析

Network protection analysis of transmission system

通信专业中的传输系统类似于铁路线路,对于信息的传递起到运输、枢纽的作用。在端到端通信流程中,需要从整网的角度对系统进行充分的保护。文章从可靠性的概念入手,分析了传输网络稳定运行的原理,介绍了可用性的计算公式,并由小及大,由物及人,从设备级别保护、网络级别保护、主动预防保护等方面,对通信传输系统的网络保护进行层层递进的探讨,给出问题对策。特别是主动预防保护,从人为的层面,本研究将主动预防纳入网络保护的范畴,未雨而绸缪,防患于未然。

The transmission system in the communication discipline is similar to the railway line,which plays a role of transportation and hub for the transmission of information.In the end-to-end communication process,the system needs to be fully protected from the perspective of the whole network.This paper starts with the concept of reliability,analyzes the principle of stable operation of transmission network,and deduces the calculation formula of availability.From the aspects of equipment level protection,network level protection,and active prevention protection,the paper discusses the network protection of communication transmission system layer by layer,and gives the problem countermeasures.In particular,active prevention,from the artificial level,brings active prevention into the scope of network protection,so as to prepare for the rainy day and take precautions.
