本文以战术地域分组交换网为基础建立具有不规则拓扑结构网络模型，在给出网络的拓扑结构、网络用户业务量和路由选择算法的条件下，提出了一种计算网络链路传输业务量的方法，并用于分析网络的传输性能。同时，还用计算机仿真方法对同一网络进行模拟。分析结果说明：这类通信网的路由选择算法的设计应更重视网络内部流量的均匀分配 In this paper, we establish a network model with irregular topology based on tactical regional packet switched network. Given the topology of the network, the traffic of network users and the routing algorithm, this paper proposes a method to calculate the network traffic Method, and used to analyze the transmission performance of the network. At the same time, computer simulations are also used to simulate the same network. The analysis results show that the design of the routing algorithm of such communication networks should pay more attention to the uniform distribution of traffic inside the network
