We analyze and compare Reno and Vegas through a number of simulations. The emphasis is the study of throughput, packet drop and fairness of Vegas under different network setting. A new modified algorithm is proposed to improve the performance of Vegas.

• 通过大量仿真对目前的TCP层的控制算法Reno和Vegas进行分析和比较，重点是对Vegas算法在不同网络情况下的吞吐量、丢包和公平性的研究，并对目前的Vegas提出一种改进算法。
