摘　　要：业务长时相关性的研究是通信网研究中的一个新热点。本文通过巧妙设计的排队仿真实验，探讨了业务长时相关性对排队性能的影响，得出和许多文献相反的结论，澄清了有关的认识，并分析了它们得出有疑问结论的原因。我们的主要结论为，业务自相关特性对排队性能有重要影响，同时，短时相关性的影响比长时相关性的影响大。Many recent researches in telecommunication area take lots of attentions to long range depen-dence(LRD) in traffic . In this paper, we study the impact of LPD on queuing performance from a lot of simula-tion experiments which are designed carefully . We draw some conclusions different with those in former papers ,and analyze the reasons why those papers gave that kind of doubtful ideas. our results indicate that the correla-tion characteristic of traffic is very important, and the short range dependence is a more dominant characteristicthan LBD.
