一种改进的EPON网络拓扑保护机制

A Novel Protection Mechanism for EPON

本文分析了目前常用的几种EPON网络保护机制存在的问题,探讨了一种改进的EPON保护机制:分支环网+全光纤保护机制。通过Matlab仿真分析证明,这种保护机制比现行各种保护机制有更好的生存性。

The article analyzes the current EPON protection mechanisms, discovers the problems in them, and discusses a novel EPON protection mechanism：ONU ring ＋all-optical-fibers protection mechanism.The article proves that this novel protection mechanical has better survivability than actual protection mechanicals by using Matlab analyzing。
