Abstract

The present disclosure relates generally to the field of migration (e.g., seamless migration) of a network connection under mobility (e.g., host mobility). In various examples, migration (e.g., seamless migration) of a network connection under mobility (e.g., host mobility) may be implemented in the form of systems, methods and/or algorithms.

Claims

1-15. -15. (canceled)

16. A computer readable storage medium, tangibly embodying a program of instructions executable by the computer for migrating communication between a client device and a first server to communication between the client device and a second server, the program of instructions, when executing, performing the following steps:

communicating, between the client device and the first server via a first communication session, wherein the first communication session has associated therewith at least one communication state;

determining, by the client device, the at least one communication state;

sending by the client device, to the second server, an identification of the at least one communication state that was determined by the client device; and

communicating between the client device and the second server via a second communication session, wherein the second communication session is based at least in part upon the identification of the at least one communication state that was sent by the client device to the second server.

17. The computer readable storage medium of claim 16, wherein the at least one communication state is a transmission state.

18. The computer readable storage medium of claim 16, wherein the first communication session has associated therewith at least a first protocol, wherein the second communication session has associated therewith at least a second protocol, and wherein the first protocol and the second protocol are the same.

19. A computer-implemented system for migrating communication from a first server to a second server, the system comprising:

a client device configured for;

(a) communicating with the first server via a first communication session, wherein the first communication session has associated therewith at least one communication state;

(b) determining the at least one communication state; and

(c) sending to the second server an identification of the at least one communication state that was determined by the client device;

wherein the client device is further configured for communicating with the second server via a second communication session, wherein the second communication session is based at least in part upon the identification of the at least one communication state that was sent by the client device to the second server.

20. The system of claim 19, wherein the at least one communication state is a transmission state.
