Abstract

An aspect of the disclosure is related to prioritizing users during a server failure. A client device or a central non-regional component detects that a server arbitrating a packet-based voice communication service in a first region has failed, and redirects the client device registered to utilize the packet-based voice communication service in the first region to a second server providing the packet-based voice communication service, wherein the redirecting is based on a priority level of a user of the client device. An aspect of the disclosure is related to peer-assisted failover recovery. A first client device detects that a server arbitrating a packet-based voice communication service in a first region has failed, and notifies a second client device in the first region that the server arbitrating the packet-based voice communication service in the first region has failed.

Claims

1. A method for prioritizing users during a server failure, comprising:

detecting that a server arbitrating a packet-based voice communication service in a first region has failed; and

redirecting a client device registered to utilize the packet-based voice communication service in the first region to a second server providing the packet-based voice communication service, wherein the redirecting is based on a priority level of a user of the client device.

2. The method of claim 1, wherein the priority level of the client device is based on a classification of the user of the client device.

3. The method of claim 1, wherein the priority level of the client device is based on an activity level of the user of the client device.

4. The method of claim 3, wherein client devices having an activity level above an activity threshold are assigned a higher priority level than client devices having an activity level below the activity threshold.

5. The method of claim 1, wherein the priority level of the client device is based on a registration time to live (TTL).

6. The method of claim 5, wherein client devices having a registration TTL expiring after a threshold period of time are assigned a higher priority level than client devices having a registration TTL expiring before the threshold period of time.

7. The method of claim 1, wherein the packet-based voice communication service comprises a voice over Internet protocol (VoIP) service.

8. The method of claim 1, wherein the detecting and the redirecting are performed by a central non-regional component.

9. The method of claim 1, wherein the detecting and the redirecting are performed by the client device.

10. The method of claim 1, wherein the user has multiple client devices registered to utilize the packet-based voice communication service in the first region, and wherein the redirecting comprises redirecting the multiple client devices to the second server.

11. A method for peer-assisted failover recovery, comprising:

detecting, by a first client device, that a server arbitrating a packet-based voice communication service in a first region has failed; and

notifying, by the first client device, a second client device in the first region that the server arbitrating the packet-based voice communication service in the first region has failed.

12. The method of claim 11, wherein the first client device detects that the server arbitrating the packet-based voice communication service has failed in response to attempting to initiate a call with the second client device over the packet-based voice communication service in the first region.

13. The method of claim 11, further comprising:

switching to a second server in response to detecting that the packet-based voice communication service in the first region has failed, wherein the second server provides the packet-based voice communication service.

14. The method of claim 13, further comprising:

establishing a call with the second client device over the packet-based voice communication service provided by the second server.

15. The method of claim 11, wherein the second client device detects that the packet-based voice communication service in the first region has failed, and in response, switches to a second server that provides the packet-based voice communication service.

16. The method of claim 15, wherein the second user device detects that the packet-based voice communication service in the first region has failed in response to an end of the call.

17. The method of claim 13, wherein the second server is in a second region.

18. The method of claim 11, wherein the notifying comprises transmitting a notification to the second client device in-band.

19. The method of claim 11, wherein the notifying comprises transmitting a notification to the second client device out-of-band.

20. The method of claim 11, wherein the packet-based voice communication service comprises voice over Internet protocol (VoIP) service.

21. An apparatus for prioritizing users during a server failure, comprising:

logic configured to detect that a server arbitrating a packet-based voice communication service in a first region has failed; and

logic configured to redirect a client device registered to utilize the packet-based voice communication service in the first region to a second server providing the packet-based voice communication service, wherein the redirecting is based on a priority level of a user of the client device.

22. The apparatus of claim 21, wherein the priority level of the client device is based on a classification of the user of the client device.

23. The apparatus of claim 21, wherein the priority level of the client device is based on an activity level of the user of the client device.

24. The apparatus of claim 21, wherein the priority level of the client device is based on a registration time to live (TTL).

25. The apparatus of claim 21, wherein the user has multiple client devices registered to utilize the packet-based voice communication service in the first region, and wherein the redirecting comprises redirecting the multiple client devices to the second server.

26. An apparatus for peer-assisted failover recovery, comprising:

logic configured to detect, by a first client device, that a server arbitrating a packet-based voice communication service in a first region has failed; and

logic configured to notify, by the first client device, a second client device in the first region that the server arbitrating the packet-based voice communication service in the first region has failed.

27. The apparatus of claim 26, wherein the logic configured to detect that the server arbitrating the packet-based voice communication service has failed comprises logic configured to detect that the server arbitrating the packet-based voice communication service has failed in response to attempting to initiate a call with the second client device over the packet-based voice communication service in the first region.

28. The apparatus of claim 26, further comprising:

logic configured to switch to a second server in response to detecting that the packet-based voice communication service in the first region has failed, wherein the second server provides the packet-based voice communication service.

29. The apparatus of claim 28, further comprising:

logic configured to establish a call with the second client device over the packet-based voice communication service provided by the second server.

30. The apparatus of claim 26, wherein the second client device detects that the packet-based voice communication service in the first region has failed, and in response, switches to a second server that provides the packet-based voice communication service.
