It is very important to simulate network in design and perforance analysis of network. This paper briefly introduces the development of network simulation, discusses the charcters of ns2, such as supporting various operation module and communication protocols,adopting OOD and strong ability for dealing with the result. Lastly this paper gives an example which simulates four nodes of network and presents the steps of simulation. This paper analyzes the strategy of random early detection. The simulation proved the feasibility and effectiveness of ns2.
