摘　　要：介绍当前主流网络仿真建模工具的建模机制,指出该机制在复杂网络条件下建模的不足。提出扩展三层建模机制,基于OPNET网络仿真工具搭建航空电信网仿真平台,在此基础上对网络服务质量进行分析并基于网络测量技术计算网络可靠度。结果表明,该机制对复杂网络的建模是有效的。This paper summarizes the three-layer modeling mechanism of those widely used tools, and points out the disadvantages of this mechanism in complex network condition. To deal with these shortcomings, an extended three-layer modeling mechanism is proposed. According to this mechanism, Aeronautical Telecommunication Network（ATN）, a rather complex network, is modeled by OPNET. By analyzing the quality of services and calculate the degree of reliability based on the network measurement, it is proved that this mechanism can model the complex network efficiently.
