Abstract
TCP Vegas is regarded as balanced congestion control strategy, however, shortcomings such as low bandwidth utilization and not gain fairness when sharing link with TCP Reno. We reinvestigate these issues and propose a modification strategy called Dynamic Vegas, which changes initial TCP Vegas’ in slow start and congestion avoidance phase. It dynamically chooses slow start algorithm and adjust decrease/increase rate in congestion avoidance phase according to specific network environment. Experiments show that within a single link network, it performs as well as TCP Vegas. Additionally, in Multi-link environment, it achieves strong competitiveness against TCP Reno and gains fairness in throughput of all senders in the end of transmission.
