摘　　要：为快速估算指定网络的时延,基于排队论理论分别对有线和无线网络子网进行建模,构建出复杂网络的排队网络模型。实现复杂网络中端到端时延的快速估算,采用opnet仿真工具分别对典型的复杂有线、无线网络以及有线加无线混合网络进行建模仿真,对比仿真结果与排队网络估算结果,其相对误差分别为16%、9.9%和13.78%。结果表明:该模型可用于网络性能的分析、复杂通信网络环境的模拟及网络优化等。In order to quickly estimate the delay of the specified network, the subnets of wired and wireless networks are modeled based on queuing theory, and the queuing network model of complex networks is constructed. In order to estimate the end-to-end delay quickly in complex networks, the opnet simulation tool is used to model and simulate the typical complex wired, wireless and wired plus wireless networks, and the relative errors are 16%, 9.9% and 13. 78% respectively by comparing the simulation results with the queuing network estimation results. The results show that the model can be used to analyze the network performance, simulate the complex communication network environment and optimize the network.
