| 摘 要： | 随着因特网流量的快速增加和对服务质量要求的不断提高,基于MPLS流量工程的QoS路由算法成为业界研究的重点。文章介绍了MPLS流量工程的工作机制和原理,在传统的Dijkstra算法的基础之上,提出了一种新颖的基于遗传优化的QoS保证的路由选择算法,同时配置一批LSP,并克服了一条一条配置时的先占先优的“顶端优势”。最后的仿真实验说明了算法在优化网络资源、平衡网络负载中是有效的和实用的。

| Abstract: | Rapid growth of Internet traffic and increasing requirement for service quality has made traffic engineering an essential consideration in the operation of large Internet backbone network.This article introduces the traffic engineering working-mechanism and operation principle.A novel QoS guaranteed routing algorithm based on GA optimization is proposed,which can configure many LSPs at the same time.It also overcomes the ″top superiority″ when configuring LSP separately.The simulation results indicate that the algorithm is practical and efficient in optimizing network resources and balancing network loads. |
