【摘要】 利用多协议标记交换MPLS(Multi-Protocol Label Switch)实施流量工程是一种具有巨大技术优势的新型技术。首先对支持流量工程的路由算法进行了分析和比较,然后对网络仿真器NS2(Network Simulator,version 2)进行扩展,实现MPLS仿真器模型。在此基础上针对不同网络拓扑和路由机制进行仿真实验,根据仿真实验的结果,对MPLS网络性能进行评估。更多还原

【Abstract】 To execute traffic engineering by using Multi-Protocol Label Switch(MPLS) is a new technology with promising technical advantage.In this paper it compares and analyzes routing algorithms for traffic engineering,and then realizes simulator model supporting MPLS by extending the network simulator NS2.Based on that,simulation experiments for different network topologies and routing mechanisms are carried out,and the performance of MPLS network is assessed by results of the simulation experiment.更多还原
