基于OPNET的MPLS实用仿真分析

Simulation Analysis of MPLS Application Based on OPNET

基于OPNET网络仿真环境对单播的数据传输模式进行了仿真，研究TMPLS技术在网络中的应用情况，通过对比分析仿真结果，表明将MPLS技术应用于传统IP网络可以有效地提高网络负载均衡、时延以及网络整体带宽的使用率等性能，尤其是对于复杂的网络更能使QoS得到优化。

Based on the OPNET Modeler, a tool for network simulation, the paper simulates the data transmit performance in Unicast mode, then studies the application of MPLS technique on the network. Comparing and analyzing the simulation results, it shows that the MPLS technique applied on the traditional IP network can efficiently improve the network load balancing, time delay and link utilization and so on. Furthermore, it can optimize the QoS （Quality of Service） more efficiently in complicated network than in simple one.
