基于分布式的电信级以太网双归保护技术

Dual-homing Protection Technology of Carrier Ethernet Based on Distribution

传统以太网双归保护是一种由一个以太网节点通过主备两条链路连接到另外一个网络区域的组网和保护技术,提高了以太网的可靠性,但是不能适应电信级以太网的分布式组网和新技术高可靠性要求。本文阐述了基于分布式的电信级以太网双归保护技术,研究了该技术的组网模型、保护倒换、恢复切换等关键技术。

Traditional Ethernet dual-homing protection is composed of a node which is interconnected by primary and secondary links to another network,which greatly improves the reliability of Ethernet,but it is not able to adapt to distributed network and meet the high reliability requirement of Carrier Ethernet.This paper explains the latest research about Carrier Ethernet dual-homing method based on distribution,and analyses the network model,protection switching,and recovery switching of key technology,and presents the advantages and prospects.
