| 摘 要： | 光纤骨干通信网中,一条光纤的断裂会引起大量业务中断.因此,对于每一条工作光路可配置一条链路分离的保护光路.采用共享通路保护时光路连接的可用性计算是网络设计时的重要问题.现对共享通路保护方式下光路连接可用性的计算给出了推导过程和一种明显的计算公式.最后给出实例,通过与仿真结果的比较验证了计算方法的正确性.

| Abstract: | In an optical fiber communication backbone network,the failure of a single fiber link can lead to huge service disruptions.Therefore,a link-disjoint protection light path can be provided for each working light path.In network design,the computation of the availability of a light path connection is very important when shared-path-protection is adopted.This paper brings forward the derivation and an explicit formula for the computation of the availability of a light path connection when shared-path-protection... |
