A Simulate Method of Multimedia End-to-End QoS Performance for the DiffServ+WLAN Networks Based on OPNET

提出一种基于OPNET的Diff Serv+WLAN网络多媒体端到端Qo S性能验证方法。该方法主要包括网络拓扑搭建和仿真配置两个模块。其中网络拓扑模块主要完成业务在Diff Serv+WLAN网络的传输过程;仿真配置模块的功能是在Diff Serv+WLAN网络拓扑中进行业务参数的配置、收集统计数据等。利用Pro-C高级语言和Visual C++6.0软件搭建Diff Serv与WLAN网络环境,对原网络和加入IPv6流标签的网络进行多媒体业务端到端Qo S性能验证方法仿真,结果表明该方法具有简单、方便等特点。

This paper presents a multimedia end-to-end QoS performance verification method for DiffServ+WLAN networks based on OPNET.The method mainly includes two modules:network topology building and network simulation configuration.The network topology building module is to perform the process of services transmitted over the DiffServ+WLAN network.The simulation configuration module is to configure the specified service parameters and collect specified statistics in the DiffServ+WLAN network topology.This paper uses Pro-C advanced programming language and Visual C++6.0 software to build a DiffServ and WLAN network,and simulates the original network and adds IPv6 stream label network to verify the end-to-end QoS performance of network multimedia.Simulation results have shown that this method has is simple and convenient.
