Abstract
The invention disclosed is a Transmission Control Protocol (TCP) transport handler for a network intermediary. The handler examines all segments in a TCP/IP data stream between two nodes The handler maintains a list of changes made by an application module to a data segment within a data stream and utilizes that list to ensure that the sequence numbers for both receiver and transmitter refer to the same segments of data. The list of changes is also used to reapply changes to retransmitted packets. Data segments are not acknowledged until the receiver acknowledges a segment, eliminating the requirement of buffering data segments.
