Equilibrium and Fairness of Networks Shared by TCP Reno and Vegas/FAST

Overview It has been proved theoretically that a network with heterogeneous congestion control algorithms that react to different congestion signals can have multiple equilibrium points. This paper demonstrates this experimentally using TCP Reno and Vegas/FAST. It also shows that any desired inter-protocol fairness is in principle achievable by an appropriate choice of Vegas/FAST parameter, and that intra-protocol fairness among flows within each protocol is unaffected by the presence of the other protocol except for a reduction in effective link capacities. Dummynet experiments and ns-2 simulations are presented to verify these results.
