Claim Text:
1. A network device comprising: a physical port for connection to a wide area network (WAN) carrying Transmission Control Protocol (TCP) traffic; a TCP receive queue coupled to said physical port to which first and second protocol data units (PDUs) are added; a PDU removal logic coupled to said TCP receive queue to pull PDUs from said TCP receive queue, wherein if the first PDU is incomplete and the second PDU is complete, said PDU removal logic pulls the second PDU prior to the first PDU being complete; and a TCP receive window advertisement logic coupled to said PDU removal logic and said port to provide a frame to the WAN which increases a TCP advertised receive window size by the size of the second PDU when the second PDU is pulled before the first PDU is complete.
