一种基于性能比较的MPLS网络动态路由算法

Performance Comparison Dynamic Routing Algorithm for MPLS network

提出了一种基于性能比较的LSP随机动态路由算法。与静态LSP建立算法相比,提出的性能比较路由算法(PCDRA)不需要假设任何详细的流量模型和不需要任何的将来请求的期望。试验结果表明PCDRA能够在不需对流量做精确预估的情况下,选择最好的路由策略。

In this paper, a new algorithm for stochastic dynamic routing of LSPs is proposed. Comparing with the off-line algorithm, out proposed algorithm（Performance Comparison Routing Algorithm） does not assume any Pcific traffic model and does not require any knowledge of future demands. Simulation result shows that the PCDRA can choice the best routing scheme without accurate a priori description of the traffic.
