摘要

针对传统保护算法对业务需求区分的不足

提出了一种改进的基于区分业务等级的光网络共享通路保护算法

该算法可以动态地为不同等级的业务选择工作路径

并实现各级业务之间的保护路径共享。改进算法不仅能够满足不同等级业务的可靠性要求

同时也缩短了高等级业务的故障恢复时间。

Abstract

In view of the deficiency of the conventional algorithms in distinguishing service requirements

this paper proposes an improved shared path protection algorithm supporting differentiated service levels in optical networks.This algorithm can dynamically select working paths for different levels of service and realize sharing of protecting paths.It does not only meet the reliability requirements of different levels of services

but also decreases the recovery time of high-level services.
