网络实验仿真与网络技术实践

Network Experiments Simulation and Network Technology Practice

探讨了网络仿真软件NS的工作原理和仿真机制,通过一个算法实例说明了网络实验的仿真过程,提出了进行网络实验仿真的方法和途径。利用IP协议路由选项和TTL字段,进行了探测网络拓扑结构的实践。通过截获并分析网络信息,加深了对网络协议的理解。

The principle and mechanism of the network simulator （NS） are discussed and analyzed in this paper. Through an example, the simulation process of network experimentation is described, and a solution of doing network experimentation emulation is presented. Using route option and TTL field of IP protocol, have implemented network topology structure detection. Network protocols are understood deeply through capturing and analyzing network information.
