摘要

本文提出了一种新的保护容量配置算法.该方法基于网络的支撑树概念

在支撑树树干和部分连枝上保留网络容量

保证网络上任何两个节点之间都有至少两条不同路由

为单一链路或节点故障提供良好的保护能力.

Abstract

One novel protection capacities reservation algorithm is proposed in this paper.Through reserving protection capacities in all trunks and partial chords on one pre-created spanning tree

the proposed algorithm assures that every node-pair on network keeps connection by at least two diverse protection routes

which can protect the networks from failing in case of the single link or node failure event.
