摘要：TCP (Transmission Control Protocol) Vegas algorithm can provide a better performance compared to the traditional TCP Reno scheme. However, there exists a serious incompatibility problem of unfair bandwidth sharing in favor of TCP Reno when TCP Vegas and TCP Reno connections coexist and share the same link in wired network. To solve this problem, we analyze the compatibility of TCP Vegas with TCP Reno and propose an enhanced Vegas algorithm G-Vegas by using the method of Game Theory. Through, the simulation experiment, the results show that G-Vegas algorithm improves the compatibility with TCP Reno and it has a better capacity in competition with the Reno for bandwidth than other improved Vegas algorithms.
