摘要
分析网络在部件不可靠时的业务性能 ,通常采用网络状态法 ,即首先得到不同状态下的性能指标 ,然后通过状态概率得到平均业务性能 .本文将考虑部件可靠性对部件业务性能的影响 ,提出一种基于不可靠设备业务性能的设备状态法 ,这相当于仅考虑一个网络状态的业务性能 ,所以比任何网络状态法简单 ,而且由于可分析设备失效而中断的业务量 ,还可以用于分析自愈网的性能 .
The current researches on traffic performance are commonly undergone by using network's state method,that we calculate the performance index of each state of network and then obtain the mean value of performance,by using the state probability.This paper discusses the effect of components' reliability on components' performance,and presents an approach,named by components' state method,which is based on the performance of components' unreliability.It can use the current performance analysis method of network with reliable components,and meantime can even analyze the breaking traffic because of components' failure,which can be used to analyze the performance of self-healing network.
