层次模型的网络性能分析系统

A layer model analysis system on network performance evaluation

具有多层次结构的大型广域网络系统的性能难以通过现有的网络管理软件和网络性能分析监控软件进行分析和监控,而具有多协议、多层次、跨区域的大型广域网络的性能更是难以控制.采用NAMS网络自动模型仿真可以对网络进行仿真,并得到网络性能的大致结果,但是通过比较发现,其与实际结果相差较大,特别是在网络负载变化剧烈的情况下.本文提出的基于层次模型系统的NPAS网络性能分析系统,能够对复杂的、负载变化的网络性能进行分析.

It is difficult to evaluate and monitor the performance of alarge wide area network (WAN's) with a multi-layer structure by using the network performance analysis and monitoring software, and the performance of a large WAN with multi-protocols, multi-layers and a large area is difficult to control. Using the NAMS network auto model we could simulate the network's operation, and obtain the result about theperformance. By comparing with the real condition, the result was found to be different from the real result,especially in heavy loads. In this paper, a layer model analysis system on network performance evaluation isgiven, which can be used for the analysis of the performance of the network with a complex structure and various loads.
