| 摘 要： | 研究了动态业务下自动交换光网络（ASOIN）的生存性，针对ASON中共享风险链路组（SRLG）故障，提出了一种基于负载均衡的SRLG共享保护通路算法（LE-SSPP）。算法调整链路的代价，采用最短路径算法找出K条SRLG分离的最短路径，选择代价（cost）和跳数（hops）最小的路径作为保护通路。仿真表明，LE-SSPP不仅能够有效的均衡负载，降低业务阻塞率，而且能满足资源利用率与故障恢复速度折衷的要求。

| Abstract: | We focus on the survivability of the Automatic Switched Optical Network(ASON) under dynamic service,propose load equalization-based SRLG sharing protection path algorithm(LE-SSPP) for Shared Risk Link Group(SRLG) failures in ASON.This algorithm firstly adjusts the cost of links,then adopts the shortest-path algorithm to find out K SRLG-disjointed shortest paths,at last chooses the least cost and hops as the protection path.The simulation results show that LE-SSPP not only balance the load effectively,reduce... |
