Abstract

Peer-to-peer mobility management in heterogeneous IP networks provides a peer-to-peer mobility module operable to intercept a data packet received at a communication protocol layer of an Internet Protocol communication stack. A translation table may be stored on memory device. The translation table stores real address of one or more network interfaces and a corresponding virtual address. The peer-to-peer mobility module may be further operable to modify the intercepted data packet using the real address and virtual address stored on the translation table.

Claims

1. A system for peer-to-peer mobility management in heterogeneous IP networks, comprising:

a peer-to-peer mobility module operable to intercept a data packet received at a communication protocol layer of an Internet Protocol communication stack; and

a translation table stored on memory device, the translation table storing real address of one or more network interfaces and a corresponding virtual address,

the peer-to-peer mobility module farther operable to modify the intercepted data packet using the real address and virtual address stored on the translation table.

2. The system of claim 1, wherein the communication protocol layer includes a link layer.

3. The system of claim 1, wherein the communication protocol layer includes one or more layer above link layer in the Internet Protocol communication stack.

4. The system of claim 1 wherein the peer-to-peer mobility module intercepts the data packet transmitted from an upper layer protocol above a link layer and modifies the intercepted data packet by replacing virtual address in the data packet with a corresponding real address before transmitting the data packet to the link layer.

5. The system of claim 1, wherein the peer-to-peer mobility module intercepts the data packet transmitted from a link layer and modifies the intercepted data packet by replacing real address in the data packet with a corresponding virtual address before transmitting the data packet to an upper layer.

6. The system of claim 1, further including a mobility center, the mobility center operable to assign a virtual address to a real address of a network interface.

7. The system of claim 6, wherein the mobility center includes memory storage device operable to store the assigned virtual address and the real address of a network interface.

8. The system of claim 6, wherein the mobility center includes a domain name server.

9. The system of claim 1, further including a mobile device having a plurality of network interfaces, the peer-to-peer mobility module installed on the mobile device.

10. A method for peer-to-peer mobility management in heterogeneous IP networks, comprising;

intercepting a data packet received at a communication protocol layer of an Internet Protocol communication stack;

determining an address of a network interface in the data packet;

modifying the data packet by replacing the address with a mapped address in the data packet; and

transmitting the modified data packet to a next layer in the Internet Protocol communication stack.

11. The method of claim 10, wherein the communication protocol layer includes a link layer.

12. The method of claim 10, wherein the communication protocol layer includes one or more layers above a link layer in the Internet Protocol communication stack.

13. The method of claim 10, wherein the data packet is intercepted from an upper layer protocol above a link layer and the intercepted data packet is modified by replacing virtual address in the data packet with a corresponding real address before transmitting the data packet to the link layer.

14. The method of claim 10, wherein the data packet is intercepted from a link layer and the intercepted data packet is modified by replacing a real address in the data packet with a corresponding virtual address before transmitting the data packet to an upper layer.

15. The method of claim 10, further including:

requesting a virtual address to be assigned to a real address of a network interface.

16. The method of claim 15, further including:

storing the virtual address and the real address.

17. The method of claim 15, wherein the virtual address is requested to be assigned from a domain name server.

18. A program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine to perform a method of peer-to-peer mobility management in heterogeneous IP networks, comprising:

intercepting a data packet received at a communication protocol layer of an Internet Protocol communication stack.

determining an address of a network interface in the data packet;

modifying the data packet by replacing the address with a mapped address in the data packet; and

transmitting the modified data packet to a next layer in the Internet Protocol communication stack.

19. The program storage device of claim 18, wherein the data packet is intercepted from an upper layer protocol above a link layer and the intercepted data packet is modified by replacing virtual address in the data packet with a corresponding real address before transmitting the data packet to the link layer.

20. The program storage device of claim 18, wherein the data packet is intercepted from a link layer and the intercepted data packet is modified by replacing a real address in the data packet with a corresponding virtual address before transmitting the data packet to an upper layer.
