| 摘 要： | ITU-T提出了以太网环网保护切换的方案,即G.8032标准.该标准采用备用链路的方法,当故障发生时,开通备用链路.但是,该标准只针对一点故障的保护,对于两点故障的保护能力还是空白,本文主要讨论基于G.8032标准的两点故障的保护.

| Abstract: | ITU proposed the program of Ethernet ring protection switching,which was the standard G.8032.The standard G.8032 introduced the means of spare link,when a fault occurred,the spare link was unclosed.The standard G.8032 introduced the means of spare link,when a fault occurs,unclose the spare link.At present time,the standard only faced to one-point fault.The ability of two-point failure protection was absent.As this reason,two-point failure protection mechanism was studied in this paper. |
