摘　　要：研究了如何在NS中创建新的网络流量发生器的问题.基于已有NS流量发生器的研究,建立一个新的VBR流量发生器模型.给出了NS中移植新流量发生器的过程,并对VBR流量发生器关键代码进行了分析.最后,通过仿真实验验证了新建流量发生器的正确性和良好的适应性.This paper researches the question of how to create a new network flows generator in NS.After study on the principle and realization of flows generator in NS, we set up a mathematical model for VBR flows generator, and propose a method of migration for a new flows generator in detail, and analyse key programming code in VBR generator. Experiments on the generation and random rate of network flows showed that the VBR generator has effective and is adaptive to network simulation in different environment with different parameters.
