摘要
针对IP网络系统时延性能的传统排队网络分析法未考虑业务的自相似性,从而导致计算结果与实际情况偏差的问题,提出经过自相似参数修正的系统时延计算方法,把每条单向线路看作1个队列,采用独立的M/M/1队列模型进行分析,所得结果再用普通的统计方法组合在一起,使结果的准确度有所改善。
Aiming at traditional queuing network analysis way unthinking of self-similar traffic, leading difference between calculation results and real situations, a new way to calculate system time delay, which has been adjusted with Hurst parameter, has been put forward. Looking upon every unilateral line as a queue, analyzed it with independent M/M/1 queue model, and combined the results with normal statistic method. The nicety of result has been improved.
