Abstract :
TCP Vegas provides significant performance gains over most TCP variants, especially when used over networks that utilise error prone links. However, whilst examining the impact of latency on TCP we noticed that the performance of TCP Vegas decreases significantly when the network round trip time exceeds 50ms. This paper details research undertaken to identify the cause of this performance decreasing behaviour in TCP Vegas. Three sender-side modifications are proposed and implemented as TCP New Vegas, before being validated via simulation
