修正开关泊松过程（RSPP）和RSPP／M／1排队

在通信网互连中，若被连子网具有不同的最大允许分组长度，那么有信关中一个较长的分组就可能要被拆分为多个较小的分组，这就是公组再分问题，已经证明，在某些情况下。再分后的公组流可以用一个修正的开关泊松过程来，本文ＲＳＰＰ和ＲＳＰＰ／Ｍ／１排队。文中推导出了ＲＳＰＰ到达间隔分布的表达式，并给出了平均到达率。文中还给出了队长分布，平均等候时间的表达式；信关输出流的特性对于全网的性能分析是必需的，因此本文着重

Reversed Switch Poisson Process(RSPP)and RSPP/M/1 Queue

in an internetwork, if different subnetworks have different packet size limits, a larger packet may have to be divided into several smaller packets in gateways.That is so-called packet fragmentation.It has been shown that the traffic stream after fragmentation can be modeled as a Reserved Switch Poisson Process (RSPP) in some cases. The purpose of this paper is to investigate some characteristics of RSPP and RSPP/M/1 queue. The expression of interarrival time distribution of RSPP is derived. The expressions for mean arrival rate, queue length distribution and average waiting time are given. These results can be used for gateway design.The characteristics of output traffic stream from gateways are necessary for performance analysis of whole internetwork, so the interdeparture time distribution is discussed and the LS transform of the distribution is presented.
