计算机网络的Petri网建模及性能指标评估

本文提出了用广义随机Ｐｅｔｒｉ网理论对计算机网络进行性能指标评估建模的具体规则，并给出了其相应的广义随机Ｐｅｔｒｉ网图，导出了依据广义随机Ｐｅｔｒｉ网模型（ＧＳＰＮ）对计算机网络中几个主要性能指标直接进行计算的方程，克服了以往在建模过程中的盲目性和无规则性．提出了从广义随机Ｐｅｔｒｉ网建模到进行计算机网性能指标计算的一系列方法．这些方法可有效地完成对计算机网络的建模和性能指标的计算，对分析和设计计算机网络具有普遍的指导意义．

GSPN Modeling and Performance Analysis Methods of Computer Networks

his paper gives a sequence of principles for the modeling of computer networks based on the Petri Net theory. The correspond GSPN model for every principle is given. The equations of index calculation for computer networks are deduced following to our modeling method. The paper presents an algorithm from GSPN modeling to indices.calculation of computer networks. It's very useful to use the qpproach that we present in this paper to analyze and design computer networks.
