摘要: 在大规模网络模拟中,由于网络流量较大导致网络模拟的性能大幅度降低。针对该问题,提出一种对网络端点流量进行缩减的网络模拟方法。该方法通过对原始网络模拟场景中的网络流量、路由器队列长度等网络模拟动态参数进行协同约简,降低模拟的计算开销,通过对约简后的网络模拟结果进行拓展,还原出原始网络模拟场景的真实结果。实验结果表明,流量约简后网络瞬时流量以及路由瞬时队列长度等网络参数有较高的可信度,而且模拟开销也大幅降低。

Abstract: In large-scale network simulation,there is a huge decrease of its performance because of the large network traffic.In order to solve this problem,a method which reduces network endpoint traffic is proposed.In this method,the computational overhead is reduced by collaborative reduction of dynamic parameters,such as network traffic flows,router queue length,etc.,in the original network simulation scene.The reduced network simulation results are expanded to restore the real results of the original network.Experimental results prove that this method can guarantee the authenticity of transient network traffic simulation,routing queue length and other network behavior parameters and reduce the cost of the simulation.

Key words: network simulation, traffic reduction, simulation performance, simulation authenticity, throughput
