1. A method for enabling a transmission control protocol (TCP) off-load, comprising the steps of:
- during establishment of a TCP connection, exchanging at least one queue identification number between a first port and a second port of the TCP connection; and
inserting at least one queue identification number in outbound data packets, wherein the first port of the TCP connection sends a data packet to the second port of the TCP connection and the second port of the TCP connection sends a data packet to the first port of the TCP connection.

Abstract
A method and system for a queue identification (QI) system which significantly reduces resources required to identify a process associated with receiving an incoming packet is provided. A QI mechanism is used as a TCP option. During a TCP connection establishment process, QI numbers are exchanged for both a sending port and a receiving port of the connection. After the connection is established, the destination QI'"'"'s number is inserted in a Transmission Control Protocol (TCP) header on outbound packets.

8. A system for enabling a transmission control protocol (TCP) off-load, comprising:
-
an exchange component, during establishment of a TCP connection, which exchanges at least one queue identification number between a first port and a second port of the TCP connection; and
an insertion component which inserts at least one queue identification number in outbound data packets, wherein the first port of the TCP connection sends a data packet to the second port of the TCP connection and the second port of the TCP connection sends a data packet to the first port of the TCP connection. - View Dependent Claims (9, 10, 11, 12, 13, 14)
