Method and system for transparent TCP offload with per flow estimation of a far end transmit window

摘要

Certain aspects of a method and system for transparent transmission control protocol (TCP) offload with per flow estimation of far end transmit window are disclosed. Aspects of a method may include storing at a network interface card (NIC) processor state information for a received TCP segment and state information for transmitted TCP segments for a determined network flow without transferring state information for the received TCP segment to a host system communicatively coupled to the NIC. The generation of a new TCP segment comprising the collected received TCP segments may be controlled based on the occurrence of a termination event and a transmit window size. The period of time for aggregation of received TCP segments may be calculated based on the sequence numbers of the next expected TCP segment and the next received acknowledgement packet.
