Abstract

A computer-implemented method for detecting TCP packet losses and expediting packet retransmission is disclosed. The method includes assigning to each packet transmitted or retransmitted a sequential order number; determining from an ACK packet or SACK segment thereof the sequential order number of a received packet; recording the determined sequential order number as a highest order number in case the determined sequential order number is greater than a current received order number, and retransmitting all unacknowledged packets having sequential order numbers less than the highest received order number.
