Analysis and Simulation of RTT Unfairness of TCP

TCP has played a key role in keeping Internet stable,however,additive increase and multiple decrease congestion window update policy of TCP led to RTT unfairness: TCP flow with little RTT will obtain more bottleneck capacity.Chiu analyzed the RTT unfairness between two TCP flow by ichnography,and RTT unfairness of TCP has been widely acknowledged.In this paper,a mathematic model of TCP congestion window update policy is built,and based on the model,TCP unfairness problem is analyzed theoretically.Moreover,the simulation results show that the mathematic model is rational.
