业务相关性对排队性能的影响及其意义

The Impact and Significance of Traffic Autocorrelation on the Performance of Queuing Systems

以TES法和洗牌法为依据，通过一系列计算机模拟实验，分析了业务相关性与排队性能之间的关系．指出：业务的相关性对排队性能有着重大的影响，对于无限排队系统，业务的长时相关性决定着排队系统的性能；而在有限排队情况下，短时相关性的影响相对大一些，且起作用的主要是相邻数据的相关性的强弱，因此短时相关性和长时相关性都不容忽略．

Based on the TES and shuffle methods, the relationship between the traffic autocorrelation and queuing performance is studied by a series of computer simulation. It is pointed out that the autocorrelation of traffic exerts a serious impact on the performance of queuing systems. Long range dependence (LRD) dominates the performance of infinite queuing systems and the performance of finite queuing systems is mainly influenced by short range dependence (SRD). So, neither LRD nor SRD can be neglected.
