Abstract

End-point devices, access points and other types of network nodes each employ multi-path management software to manage communication via multiple possible paths to the Internet backbone from communication applications that run on an end-point device. The multi-path management software on an end-point device may operate independently and/or cooperate with the local communication applications and the multi-path management software located on the access points or other network nodes to select one or more pathways for the local communication applications. The multi-path management software depending on data types and data requirements also supports selection and maintenance of two or more paths that simultaneously serve a single communication application. The multi-path management software of an end-point device may pass all or a portion of multi-path management responsibility to a local communication application and/or to multi-path management software of another network node. In addition to managing the selection of one or more pathways, the multi-path management software seamlessly switches pathways as may become necessary to meet changing network conditions or bandwidth demands.

Claims

1. An access point comprising:

at least one communication interface that services communications between an end point device and a plurality of networks; and

at least one processor that controls communication between the end point device and the plurality of networks via the at least one communication interface, wherein the at least one processor;

determines a plurality of distinct communication pathways between the end point device and the plurality of networks;

establishes a first link combination of the plurality of distinct communication pathways to service communications between the end point device and the plurality of networks;

periodically, determines the sufficiency of the first link combination for servicing the communications;

when the first link combination is insufficient for servicing the communications, establishes a second link combination between the end point device and the plurality of networks without notifying the end point device, the second link combination differing from the first link combination.

2. The access point of claim 1, wherein the first link combination is to one of the networks and the second link combination is to a differing one of the networks.

3. The access point of claim 1, wherein the first link combination and the second link combination is to a same one of the networks but with differing link capacity.

4. The access point of claim 1, the at least one communication interface comprises:

at least one wireless interface; and

at least one wired interface.

5. The access point of claim 1, wherein the first link combination is insufficient for servicing the communications when the end point device serviced by the access point has increased communication requirements.

6. The access point of claim 1, wherein the first link combination is insufficient for servicing the communications when a differing end point device serviced by the access point has increased communication requirements.

7. The access point of claim 1, wherein the first link combination is insufficient for servicing the communications when the at least one communication interface has altered communications capacity.

8. The access point of claim 1, wherein the first link combination is insufficient for servicing the communications when an application running on the end point device serviced by the access point notifies the access point of impending increased communication requirements.

9. The access point of claim 1, wherein the first link combination is insufficient for servicing the communications when an application running on another end point device serviced by the access point notifies the access point of impending increased communication requirements.

10. The access point of claim 1, wherein the first link combination has a first number of communication links and the second link combination has a second number of communication links that is greater than the first number of communication links.

11. A method for operating an access point having at least one communication interface that services communications between an end point device and a plurality of networks, the method comprising:

determining a plurality of distinct communication pathways between the end point device and the plurality of networks;

establishing a first link combination of the plurality of distinct communication pathways to service communications between the end point device and the plurality of networks;

periodically determining the sufficiency of the first link combination for servicing the communications;

when the first link combination is insufficient for servicing the communications, establishing a second link combination between the end point device and the plurality of networks without notifying the end point device, the second link combination differing from the first link combination.

12. The method of claim 11, wherein the first link combination is to one of the networks and the second link combination is to a differing one of the networks.

13. The method of claim 11, wherein the first link combination and the second link combination is to a same one of the networks but with differing link capacity.

14. The method of claim 11, the at least one communication interface comprises:

at least one wireless interface; and

at least one wired interface.

15. The method of claim 11, wherein the first link combination is insufficient for servicing the communications when the end point device serviced by the access point has increased communication requirements.

16. The method of claim 11, wherein the first link combination is insufficient for servicing the communications when a differing end point device serviced by the access point has increased communication requirements.

17. The method of claim 11, wherein the first link combination is insufficient for servicing the communications when the at least one communication interface has altered communications capacity.

18. The method of claim 11, wherein the first link combination is insufficient for servicing the communications when an application running on the end point device serviced by the access point notifies the access point of impending increased communication requirements.

19. The method of claim 11, wherein the first link combination is insufficient for servicing the communications when an application running on another end point device serviced by the access point notifies the access point of impending increased communication requirements.

20. The method of claim 11, wherein the first link combination has a first number of communication links and the second link combination has a second number of communication links that is greater than the first number of communication links.
