Transmission Control Protocol (TCP) fails to fully utilize bandwidth due to the limitation in its Conservative Congestion (CC) algorithm. It assumes that every packet loss is caused by network congestion and initializes its congestion control algorithm. Receiver-Assisted Congestion Control (RACC) mechanism, in which the sender performs loss-based control, while the receiver is performing delay-based control. The receiver measures the network bandwidth based on the packet inter-arrival interval and compute a congestion window size deemed appropriate for the sender. After receiving the advertised value and then feeds this information back to the sender.
