Abstract

A resegmentation entity implements a TCP resegmentation technique wherein a receiving host receives packets that appear as if it they have been transmitted specifically for the receiving host's MTU. The receiving host does not require the buffering and CPU utilization necessary for IP reassembly. Thus, the receiving host has a lower latency when receiving IP datagrams that contain resegmented TCP segments than it would if it needed to re-assemble an IP datagram from fragments before it could process the TCP segment. Further, the sending host transmits TCP segments at its largest MTU, without regard to the receiving station's MTU, knowing that the intermediate routing entity insures that TCP resegmentation occurs. In the event that an IP datagram containing a resegmented TCP segment is lost, the sending host only has to retransmit the actual TCP data that was lost, and not the complete TCP segment.
