A novel fair bandwidth allocation algorithm for TCP window control

Without appropriately fair buffer management in the network, TCP encounters inherent unfairness towards connections with long round-trip times. The paper proposes a proportional fairness algorithm to correct the bias against these long connections. The algorithm is proven to converge to the fair point using the Lyapunov function. The basic algorithm is further modified to smooth the bursts of traffic. With these modifications, simulation results show that not only can our algorithm. improve TCP fairness, but it can obtain good throughput performance as well.
