NS在网络教学中的应用

the Usage of NS in Network Teaching

计算机网络、数据通信技术等课程枯燥乏味,抽象难懂,在实验室中构建大范围的实验床存在资金和网络条件的限制,而仅仅基于原有局域网进行实验评估又无法再现某些网络现象以及对网络性能进行直观、可靠的测评。因此,可以尝试将网络仿真软件NS运用到网络课程教学当中,通过使用网络模拟器辅助计算机网络与数据通信教学,通过计算机网络仿真实验,把抽象的网络概念形象化,把枯燥的网络原理具体化。本文通过一个实例具体演示NS在网络教学中如何应用。

The courses of network, data communication technology etc, are boring and abstract. Buliding a large -scale testbed in lab has fund and network condition restrictions. And doing experiment based on the old LAN condition can not reappearant some network phenomenon and can not do intuitionistic and reliable measurement. So we try to use network emulator NS in the teaching of network course. By the assistant of NS, we can make the abstract network concept visualized, the bald network theory embodied. In this paper we give an example to show how to use NS in the network teaching.
