模拟仿真网络到真实网络的接口的研究和实现

The Research of the Interface between the Simulated Network and the Real Network

网络仿真软件已成为研究、规划、设计网络不可缺少的工具。文章主要讨论了仿真网络与真实网络接口模块的原理,并应用NAT和代理服务器技术对其进行了开发实现。经在NetSim仿真软件上验证,其实现了软件层次上的透明代理,扩展了仿真软件的应用范围。

The interface module of network simulator performs the data exchanging between the simulated network and the real network.This paper introduces the NAT and proxy protocol which the interface module is based on,and illustrates the realization of the interface module at the NetSim platform.
