A Modified Explicit Congestion Control Algorithm

EMKC is an explicit congestion control algorithm which is designed for high bandwidth delay product (BDP) networks. Although delay-independence is an appealing characteristic, the EMKC system developed in exhibits undesirable equilibrium properties and slow fairness convergence behavior. To overcome these drawbacks, we propose a new method called MEMKC (Modified Exponential Max-Min Kelly Control). In this paper, we investigate MEMKC, prove its stability with homogeneous delay and also study the convergence behavior of MEMKC. Extensive simulations confirm that MEMKC eliminates stationary packet loss while speeding up the fairness convergence rate. Simulations also show that MEMKC preserves the good properties of EMKC, such as delay-independent stability and max-min fairness in steady state.
