摘　　要：基于IP/WDM网络的对等模型,在联合路由的基础上,对SRLG约束的联合共享链路保护机制的路由选择与资源分配算法进行了研究,并提出了一种新的MI-APF-ISLP算法。为了验证该算法的有效性,以自相似和Poisson模型两种业务模型为基础,将连接阻塞概率CBP和带宽吞吐率BTP作为性能指标,在不同参数条件下进行动态仿真,结果表明MI-APF-ISLP算法要优于传统算法。Based on the peer model of IP/WDM network, the integrated shared Link protection routing algorithms in IP/WDM networks under shared risk link groups constraints is studied in this paper, and a new routing algorithm-MI-APF-ISLP is proposed. In addition, using connection blocking probability and bandwidth throughput probability as performance metrics, we analyze and compare the performance of proposed survivable routing algorithm under Self-similar and Poisson traffic, and result shows the network performance of MI-APF-ISLP is better than the traditional algorithm.
