摘　　要：基于NS2仿真平台,在覆盖多播网络环境下,分别从组成员个数,节点速度两个方面对其进行模拟仿真;以延迟、数据转发率和控制开销几个指标综合评价覆盖多播在不同网络环境下的性能优劣。对于NS2模拟,为了得到更接近于真实网络环境的仿真结果,实验都在仿真10次的基础上以0.95为置信水平对10次仿真结果取平均,以得到更精确的结果。Based on the NS2 simulation,this study adopts the group size and speed to implement the simulation with the coverage of multicast network.There are three indexes including latency,delivery ratio,control overhead and the indexes can evaluate the quality of the overlay multicast comprehensively under the various internet conditions.For the NS2 simulation,in order to simulate the real internet circumstance exactly and gain a most appropriate result,every experiment simulates at least for ten times,otherwise,the experiment sets the 0.95 as confidence level and obtains average numerical value from the ten experiments to guarantee the reliance of the simulation result.
