Abstract
A method and system for employing the time stamp and SACK options in TCP and SCTP to modify their operation to initially only send new or lost packets, after a network timeout has occurred. Wireless network resources are saved by reducing the number of packets that are resent to a destination. In particular, the invention detects whether an acknowledgement from a destination is associated with the originally sent packet or a resent packet and uses this information to modify the operation of the protocol to reduce congestion on the network.
