Abstract:

With the development of the Internet, congestion has become more and more serious, and good congestion control algorithms are needed. Vegas is a good algorithm for its active avoidance of congestion, however, it can not work well with the mainstream algorithm Reno because its bandwidth can be stolen by Reno. This paper  analyzes the problem between Vegas and Reno, with a method of game theory, and proposes an advanced congestion control algorithm GVegas. According to the results of emulation on NS2, the algorithm is effective.
