| 摘 要： | 针对MPLS网络,提出一种带宽时延约束路由改进算法,引入节点负荷率的限制,在路由时避开负载较重的链路,在保证用户业务带宽与时延约束的前提下,为一部分流量寻找一条相对较长但负载较轻的路径,以使得整个网络的流量分布更加均衡,从一定程度上可以减少网络拥塞。从仿真实验结果来看,改进后的算法在吞吐量、请求建立的成功率以及端到端时延等性能方面有比较好的表现。

| Abstract: | This paper presents an improved delay and bandwidth constrained-based routing algorithm for the MPLS networks.By limiting the load rate of the nodes in the network,some traffic would pass a longer but lightly loaded path that satisfies two constraints bandwidth and delay,better than the heavily loaded shortest path.It means that traffic load in the network will be adjusted to a balance level and con-gestion would be avoided from a certain extent.The simulation results show that the proposed algorithm has a ... |
