This paper introduces a new TCP congestion control mechanism for rate-limited applications that transmit data in bursts and do not fully utilise their allowed transmission rate. We propose “new-CWV”, a method that allows a TCP connection to restart quickly from either an idle or application-limited period. Simulation results show that this provides faster convergence to the rate requested by a rate- limited application, demonstrated by a higher throughput, and better utilisation of unused capacity compared to Standard TCP or TCP with Congestion Window Validation.
