利用1+1线性复用段保护技术实现跨环业务的保护

Realizing Protection for Cross-loop Services by Linear Multiplex Section

随着同步数字传输技术日趋成熟和网络承载的业务不断扩大 ,对骨干传输网络的安全要求也愈来愈高。在环网对接点实现有效保护 ,对全网的安全运行起着举足轻重的作用。着重描述了1 + 1线性复用段保护的实现原理 ,并结合此保护的实现原理对现网中一些对接业务提出保护建议。

With the maturity of synchronous digital transmission technologies and the enlargement of network bearing services,more and more attention are paid to the security of the backbone transmission network.Realizing effective protection for the loop interconnecting nodes plays an important role in ensuring network security.This article mainly introduces the principle of the 1+1 linear multiplex section protection (MSP).Suggestions on interconnection services on existing network are given according to the principle described.
