摘要

基于Petri网模型方法和仿真方法

对一种低轨/中轨/同步地球轨(LEO/MEO/GEO)三层卫星网络进行了性能分析.首先建立了卫星网络的广义随机Petri网(GSPN)模型

采用SPNP6.0软件进行了网络性能分析.然后

将分析结果与采用OPNET软件对该三层卫星网络模拟的结果进行了比较

验证了模型的正确性

并得出了诸如在高网络负载的情况下三层网络结构的性能优于单层等新的结论.

Abstract

The performance evaluation on a triple-layered LEO/MEO/GEO satellite network is carried out by Petri Net-based analysis and software simulation.The GSPN model of a triple-layered satellite network is constructed

and then used to evaluate the network performance with SPNP (Stochastic Petri nets Package) 6.0 software.The effectiveness of the results obtained by Petri Net-based analysis is verified in comparison with these by network simulation using OPNET

and some new results

such as the performance of the triple-layered network is better than that of LEO one under high load

are derived thereby.
