为了提高网络的效能,需要不断研究新的网络协议和算法。而要在实际的网络环境中验证和测试它们会受到网络的复杂性和经济等因素的限制,而网络仿真能很好地解决这个问题。另外,在网络教学中,网络仿真也可形象展示网络协议的行为。文章首先介绍了网络仿真工具ns2的体系结构,并重点剖析了分裂对象模型的设计原理,以分析计算网络性能来说明ns2的应用以及如何扩展ns2的功能,并演示了抖动率的计算效果。
In order to improve the performance of the network, we need to constantly study new network protocols and algorithms. To verify and test them in the actual network environment will be limited by the complexity of the network and economic factors, and network simulation can well solve this problem. In addition, in online teaching, network simulation can also display the behavior of network protocols. The article first introduces the architecture of network simulation tool ns2, and analyzes the design principle of split object model. It analyzes the application of ns2 to explain the application of ns2 and how to extend the function of ns2. And it also shows the effect of jitter calculation.
