Abstract:
1. A method comprising: checking whether a first priority associated with a new incoming packet of a Transmission Control Protocol (TCP) connection between a first host and a second host is greater than a second priority associated with a previous incoming packet of the TCP connection; transmitting the new incoming packet at the first priority if the first priority is not greater than the second priority; if the first priority is greater than the second priority, determining whether the new incoming packet will arrive substantially out of order in that the new incoming packet will arrive before the previous incoming packet such that retransmission of the previous incoming packet or the new incoming packet will result; transmitting the new incoming packet at the first priority if the new incoming packet is not determined to arrive substantially out of order with respect to the previous incoming packet; and transmitting the new incoming packet at the second priority if the new incoming packet is determined to arrive substantially out of order with respect to the previous incoming packet.
