摘　　要：仿真和测试是研究组播路由问题的重要方法,但Waxman随机网络模型不能用于测试动态组播路由算法。根据组播成员动态加入和退出时对组播性能和质量的影响程度,提出一个模拟组播组动态变化的模型,按加入和退出的平衡态建立概率分布函数,移植和改造了MCRSIM(MultiCastRoutingSIMulation)仿真工具,使其有效地模拟组播组成员动态变化的网络情况,以便对动态组播路由算法进行试验和测试。该模型不仅能仿真随机网络中组播成员动态变化情况,而且能仿真组播源变化的情况。该成果已应用于动态组播路由算法的研究之中。The methods of simulation and test are playing important role on multicast routing. The dynamic multicast routing algorithms could not be tested by Waxman's network model. Members join or leave from a multicast group can impact multicast capability and quality, so a method for simulating change of the multicast members has been raised from MCRSIM(MultiCast Routing SIMulation). The MCRSIM has been transplanted and renovated. The new tool can simulate members join or leave from a multicast group, and the adaptation between source member and general members. It is has been used for experiment and test dynamic multicast routing algorithms. 
