以太网 Ring Protection Switching (ERPS)

As many networks move toward carrier 以太网 and replace SONET/SDH networks, ring recovery and interoperability between brands are growing concern. One main concern is preventing a broadcast storm while minor differences between devices result in less resiliency and longer training and setup times.

作为解决这一问题的努力, ITU-T (International Telecommunication Unit) created 以太网 Ring Protection Switching (ERPS) under G.8032人推荐. ERPS helps achieve high reliability and network stability by providing sub-50ms protection and recovery switching for 以太网 networks in a ring topology. Loop avoidance is done by designating one ring node as responsible for blocking traffic. When a link fails, the designated node unblocks allowing traffic to continue.

G.8032 standard protocol allows users to have different brands while ensuring network reliability and resiliency. G.8032v1 supported a single 以太网 ring while G.8032v2 added more features including support for multiple rings/ladder network.

E-Line:以太网虚拟专用线

以太网 Private Line (EPL) or 以太网 Virtual Private Line (EVPL) provides dedicated bandwidth between two points. Using an 以太网 virtual connection (EVC) between a pair of dedicated user-network interfaces (UNIs), E-line replaces traditional private line services and offers more bandwidth at a lower cost.

EVPL allows users to instantly and 安全ly communicate between two UNIs. This private connection heightens network efficiency providing stable, 安全, 和高效的数据传输.
