Inter-Protocol Fairness Between TCP New Reno and TCP Westwood+

Tags:
bandwidth issues

Overview This paper investigates the effect of introducing TCP Westwood+ on regular TCP New Reno. By means of analytical modeling and ns-2 simulations, the paper demonstrates that the two protocols get different shares of the available bandwidth in the network. The main result is that the bandwidth sharing between the two protocols depends on one crucial parameter: the ratio between the bottleneck router buffer size and the bandwidth delay product. If the ratio is smaller than one, TCP Westwood+ takes more bandwidth. On the contrary, if the ratio is greater than one, it is TCP New Reno which gets the larger part.
