A new congestion control protocol is presented, analyzed and experimentally evaluated. It consists of the standard inner-loop ACK-clock and a novel outer-loop adjusting the window size based on congestion signaling from the network. The aim of the new protocol is to maintain the efficiency and fairness properties of TCP, but with significantly smaller bottleneck queues and thereby it takes the sharing with real-time traffic into account. Stability properties of the protocol is proved using a recent fluid-flow traffic model. Experimental comparisons with New Reno and Vegas illustrate the advantages of the new protocol with respect to throughput, delay, utilization, and fairness.
