Abstract

Systems of redundantly clustered machines to provide failover mechanisms for mobile traffic management and network resource conservation are disclosed. One embodiment includes a system of redundantly clustered machines to provide failover mechanisms for mobile traffic management and network resource conservation including, a first set of redundantly clustered machines coupled to a second set of redundantly clustered machines via a common repository node where each of the first and second set of redundantly clustered machines function independently to provide mobile traffic management or network resource conservation services. The first and second set of redundantly clustered machines can be physically located in different data centers or in the same data center.

Claims

1. A system for mobile traffic management and network resource conservation with fault tolerance mechanisms, the system, comprising:

a first arm of servers to perform mobile traffic management or network resource conservation services;

a second arm of servers to perform mobile traffic management or network resources conservation services;

a storage component to which the first arm of servers and the second arm of servers are coupled.

2. The system of claim 1, wherein, the first and second arms of servers are physically located in different data centers.

3. The system of claim 1, wherein, the first and second arms of servers are physically located in a same data center.

4. The system of claim 1, further comprising additional arms of servers coupled to the storage component.

5. The system of claim 1, wherein, the first arm of servers includes, one or more of, a notification server, a relay server, a policy management server, a traffic harmonizer server.

6. The system of claim 5, wherein, the first arm of servers further includes, a polling server.

7. The system of claim 1, wherein, the first arm of servers includes, a polling server and a traffic harmonizer server.

8. The system of claim 5, wherein, the notification server is included in the first arm of servers in redundancy;

wherein, the relay server is included in the first arm of servers in redundancy.

9. The system of claim 5, wherein, the policy management server is included in the first arm of servers in redundancy;

wherein, the traffic harmonizer server is included in the first arm of servers in redundancy.

10. The system of claim 6, wherein, the polling server is included in the first arm of servers in redundancy.

11. A system of redundant clustered machines to provide failover mechanisms for mobile traffic management or network resource conservation services, the system, comprising:

a first set of redundantly clustered machines coupled to a second set of redundantly clustered machines via a common repository node;

wherein, each of the first and second set of redundantly clustered machines function independently to provide mobile traffic management or network resource conservation services.

12. The system of claim 11, wherein, subscription information for a mobile device serviced by the first set of redundantly clustered machines is accessible by the second set of redundantly clustered machines via the common repository node.

13. The system of claim 11, wherein, the first set of redundantly clustered machines located in a given location is able to service a mobile device until the mobile device roams to another location serviced by the second set of redundantly clustered machines.

14. The system of claim 11, wherein, the first set of redundantly clustered machines located in a given location is able to service a mobile device unless a failover occurs at the given location.

15. The system of claim 11, wherein, the first set of redundantly clustered machines located in a given location is able to service a mobile device;

wherein, given capacity issues at the given location, the mobile device is transferred to be serviced by the second set of redundantly clustered machines at a different location;

wherein, subscription information for the mobile device is loaded on the second set of redundantly clustered machines from the common repository node.

16. The system of claim 11, wherein,

the first set of redundantly clustered machines includes, one or more of:

a notification component;

wherein, the notification component includes multiple notification servers; and

wherein, the policy management component includes multiple policy management servers.

18. The system of claim 11, wherein, the first set of redundantly clustered machines includes, one or more of:

a traffic harmonizer component;

wherein, the traffic harmonizer component includes multiple traffic harmonizer servers;

a polling component;

wherein, the polling component includes multiple polling servers.

19. A method for providing fault tolerance in mobile traffic management services, the method comprising:

detecting that one component of multiple components for providing mobile traffic management services is non-operational, at capacity or near capacity;

identifying mobile devices serviced by the one component;

retrieving, by a remaining set of the multiple components exclusive of the one component, subscription information for the mobile devices serviced by the one component, from a storage component coupled to the one and the multiple components.

20. The method of claim 19, further comprising, allocating the mobile devices originally serviced by the one component, among the remaining set of the multiple components for servicing, using the subscription information.

21. The method of claim 20, wherein, one of the remaining set of the multiple components polls associated hosts for subscriptions of its allocated subset of the mobile devices originally serviced by the one component, using the subscription information.

22. The method of claim 21, wherein, invalidations of cache entries on the mobile device are sent to the allocated subset of the mobile device originally serviced by the one component, from one of the remaining set of the multiple components in clear text;

wherein, the cache entries were stored on the mobile device for mobile traffic management.

23. The method of claim 22 wherein, the invalidations are sent via SMS in clear text.

24. The method of claim 19, wherein, the one component is detected to be non-operational by the mobile device which it services.

25. The method of claim 19, wherein, the one component is detected to be non-operational by others of the multiple components.

26. A method for utilizing fault tolerance failover provided by a mobile traffic management service, the method comprising:

in response to detecting, by a mobile device, that connection to one component of multiple components for providing mobile traffic management services cannot be established;

connecting to another component of the multiple components;

negotiating a new encryption key with the other component for secure communication with the other component;

wherein, the mobile device is assigned a unique identifier by the other component;

receiving, at the mobile device, content received as a result of polling by the other component of the multiple components. retrieving, by a remaining set of the multiple components exclusive of the one component, subscription information for the mobile devices serviced by the one component, from a storage component coupled to the one and the multiple components.

27. The method of claim 26, wherein, the detection is performed by an operating system of the mobile device.
