摘要
Abstract
TCP Vegas protocol employs difference between the expected throughput and the actual throughput to control network congestion. Compared with the TCP Reno protocol, it has better network stability and availability. In this paper we confirm that the TCP Vegas protocol has poorer fairness in coexistence environment by analysing the network performances of these two protocols in complex environment, and then propose an improved network-based adaptive TCP Vegas algorithm. This algorithm exalts the adaptability of TCP Vegas protocol in complex environment by adaptively improving the expected throughput and optimising the detection of queue congestion, it also enhances the fairness of the TCP Vegas when coexisting with TCP Reno. Simulation demonstrates in the end the validity of the improved algorithm.关键词
