Traditional congestion control algorithms exhibit low convergence rate to equilibrium when the network capacity is very large. In this paper, we present a new algorithm called Quick Kelly Control (QKC) to accelerate the convergence rate. The link utilization ratio functions are used as feedback signal and a novel nonlinear update law is constructed. The stability of this new algorithm is partly proved without considering delay. We also compare this algorithm with two classic algorithms and give
