TCP性能分析。两个分析模型：拥塞控制，各种场景；给出仿真练习；-two analytical models for TCP’s throughput are compared with simulated results. Based on the study, an ns2 simulation exercise is developed for the course “Simulation of telecommunications networks”. The goal of t

Congestion is an important issue which researchers focus on in the Transmission Control Protocol (TCP) network environment. To keep the stability of the whole network, congestion control algorithms have been extensively studied.

The RED active queue management algorithm allows net- work operators to simultaneously achieve high throughput and low average delay. However, the resulting average queue length is quite sensitive to the level of congestion and to the RED paramet
