摘要
弹性分组环 ( RPR)是由顺时针、逆时针两个传输方向的光环组成的 .其保护倒换机制主要有两种 :采用源路由保护机制和采用回绕保护机制 .文章将分析 RPR的保护倒换机制 .
The RPR network consists of a mandatory protection mechanism called steering, and an optional protection mechanism called wrapping. The protection protocol is completely defined for both mechanisms, and either by itself is sufficient to meet RPR requirements.
