基于业务的网络可靠性试验流量生成方法研究

网络的发展从仅关注速度的提升转移到关注业务的交付能力,由此网络可靠性问题越来越受到研究者的重视。网络可靠性试验是评价网络可靠性的一种重要手段,而试验流量的生成对可靠性评价结果具有决定性的影响。然而目前从可靠性角度对网络进行试验时,对任务的描述较为简单,无法支撑由客户需求分解到网络流量生成的全过程;从流量模型角度出发的生成技术则仅关注全网流量,难以支持可靠性试验中的流量生成。本文提出基于业务的混合模型的流量描述方法,并使用软件实现,最后进行试验验证所提出方法的有效性。

Research on Application Based on Trafifc Generation Method in Network Reliability Test

Network researchers have adjusted their focus from just improving speed to overall service delivery capability. Thus, network reliability issues have gained more and more attention. Among these issues, network reliability test is a vital and important way to evaluate the reliability level, during which traffic generation plays a decisive impact on the evaluation results. However, the existing reliability test describe missions roughly, which are not enough to support the whole decomposition process from client requirements to traffic generation; while, traffic models can tell the statistic traffic, but not specific applications. This paper proposed a hybrid traffic model based on the concept of application and realized this method by using software. Finally, a case was studied to verify its effectiveness.
