ABSTRACT:
A method, network receiver and TCP network that enables a receiver-side triggering of the fast retransmit mechanism when a TCP packet/segment is lost or received out-of sequencing order. The receiver is enhanced with a Fast Retransmit Support (FRS) utility that monitors when a next received packet is out-of-order and responds by transmitting a duplicate acknowledgment (ACK) response that includes therein the same window value as the previous ACK. By including the previous clock time, even when the current window value has advanced, the fast retransmit algorithm at the transmitter is triggering before the timeout period.
