Efficient congestion control should fully use the bandwidth for a large network with many routers and terminals. This paper develops a congestion control algorithm based differential equations' fluid model. The proposed control algorithm considers that under many flows, the stability of the fluid model ensures the convergence of the average rate to its equilibrium point, may impose excessive restriction of our choice of AQM parameters. Simulations verify the proposed control design can avoid of the congestion problem of bottleneck network. Under many flows with large capacity, simulations have shown that the AQM system utilization still approaches to full utilization, while the buffer size on the order of bandwidth-delay product is necessary for the stability of the fluid model with full utilization.
