摘要

弹性分组环（RPR）技术定义了一种新型的媒体接入控制（MAC）层协议

采用了共享介质传输和空间复用协议以及低于50 m s的故障恢复保护的弹性机制

支持服务等级协定（SLA

Service Level Agreem ent）

即插即用

基于MAC的高速交换

可承载具有突发性的IP业务

同时支持传统的语音传送

是未来城域网技术的重要发展方向。光纤技术的飞速发展使得RPR不再仅仅局限于城域网

还可以用于广域网。文章在基于RPR的低于50 m s的故障恢复保护的基础上

提出了具有高生存性的解决方案。

Abstract

Resilient Packet Ring（RPR） technology defines a new type of Media Access Control（MAC） level protocol

which adopts shared medium transmission

a spatial reuse protocol and a <50 ms failure recovery protection mechanism

supporting Service Level Agreements（SLA） and plug-and-play.As an important technology for the future Metropolitan Area Network（MAN） with MAC-based high speed switching

RPR can carry burst IP service while supporting conventional voice transmission.With the rapid development of fiber technology

RPR can be used for both MAN and WAN.On the basis of RPR-based <50 ms failure recovery protection mechanism

a new high survivability network solution is presented in this paper.
