Abstract

A method and apparatus for improving the data transfer rate of packet-switched networks that employ retransmission timers is disclosed. Upon receipt by a sender of an acknowledgment message indicating that the intended recipient received a data packet, a retransmission timer is initialized with a value that compensates for the time lag between the transmission of a data packet by the sender and the receipt of an acknowledgment message. A communication network includes data transfer terminals that, upon receipt by a sender of an acknowledgment message indicating that the intended recipient received a data packet, initialize a retransmission timer with a value that compensates for the time lag between the transmission of a data packet by the sender and the receipt of an acknowledgment message.
