摘要
针对网络仿真中的关键问题———流量的仿真与建模,分析了IP网络流量的特点和软件仿真系统OP NET的流量仿真建模机制,详细阐述了一种基于OPNET仿真平台建立IP网流量模型的方法。该方法将流量仿真分成背景路由流量建模、背景利用率流量建模和前景业务流量建模3部分,并综合利用网管导入流量和业务源建模来建立流量模型。最后通过仿真建模验证了该方法的有效性。
Aimed at the key-point of the network simulation--traffic simulation and modeling, the characteristics of the traffic in the IP networks and the traffic modeling mechanism based on the OPNET are researched, and a new means is put forward. In this means, the traffic model is composed of background routed traffic and background utilization traffic and application traffic, which can be completed with the tools in the network management system and modeling by hand. And the simulation model is validated on the OPNET platform in the end.
