Abstract

A system identifies a network socket on a machine by assigning a non-IP address socket anchor and a port number to the network socket. A socket anchor may comprise a globally unique number. In some embodiments, a socket anchor comprises a number having a preselected number of bits. The number having the preselected number of bits may comprise a selected number associated with the machine concatenated with a number of randomly generated bits. The number of bits of the selected number plus the number of randomly generated bits is equal to the preselected number of bits. In some embodiments, the selected number associated with the machine is a Media Access Control (MAC) address of a network interface associated with the machine.

9. A system, which comprises:

a machine;

a network interface associated with said machine;

a network socket on said machine, said network socket being identified by a non-IP address socket anchor and a port number;

a protocol stack running on said machine, said protocol stack including a transport layer, said transport layer being configured to;

receive a packet, said packet including data, and said packet including said socket anchor and said port number; and

,

forward said data to said network socket.

10. The system as claimed in claim 9, wherein said socket anchor comprises a globally unique number.

11. The system as claimed in claim 9, wherein:

said socket anchor comprises a number having a preselected number of bits.

12. The system as claimed in claim 11, wherein said number having said preselected number of bits comprises:

a selected number associated with said machine, said selected number having a number of bits fewer than said preselected number of bits; and

,

a number of randomly generated bits concatenated with said selected number, wherein the number of bits of said selected number plus said number of randomly generated bits is equal to said preselected number of bits.

13. The system as claimed in claim 12, wherein said selected number associated with said machine comprises a Media Access Control (MAC) address of said network interface.

14. The system as claimed in claim 9, wherein said packet includes a transport layer header and said socket anchor and said port number are carried in said transport layer header.

15. The system as claimed in claim 14, wherein said packet comprises a Transmission Control Protocol (TCP) segment.

16. The system as claimed in claim 9, wherein said socket anchor is carried as an option in an Internet Protocol (IP) header.

17. A computer program product in computer readable storage medium, said computer program product comprising:

instructions stored in said computer readable storage medium for receiving a packet, said packet including data, and said packet including a non-IP address socket anchor and a port number; and

,

instructions stored in said computer readable storage medium for forwarding said data to a socket, said socket being identified by said socket anchor and said port number.

18. The computer program product as claimed in claim 17, wherein said socket anchor comprises a globally unique number.

19. The computer program product as claimed in claim 17, wherein:

said destination socket anchor comprises a number having said preselected number of bits.

20. The computer program product as claimed in claim 19, wherein said number having said preselected number of bits comprises:

a selected number associated with a machine, said selected number having a number of bits fewer than said preselected number of bits; and

,

a number of randomly generated bits concatenated with said first selected number, wherein the number of bits of said selected number plus said number of randomly generated bits is equal to said preselected number of bits.

21. The computer program product as claimed in claim 20, wherein said selected number associated with said machine comprises a Media Access Control (MAC) address of a network interface associated with said machine.

22. The computer program product as claimed in claim 17, wherein said packet includes a transport layer header and said socket anchor and said port number are carried in said transport layer header.

23. The computer program product as claimed in claim 22, wherein said packet comprises a Transmission Control Protocol (TCP) segment.

24. The computer program product as claimed in claim 17, wherein said socket anchor is carried as an option in an Internet Protocol (IP) header.
