Abstract

Synchronization of data across multiple endpoints in a mesh network that supports a data sharing service is throttled responsively to user activity in the network by monitoring the activity using a component in a mesh operating environment (“MOE”) runtime that is instantiated on each endpoint. The monitoring may include the collection of data that can be used to infer user activity, as well as data that explicitly indicates activity. State information is maintained so that data can be synchronized across the endpoints even when a user goes offline from the service. When the user logs on to the service, makes changes to a shared file, or the endpoint device starts up upon connection to a mesh network, throttling is performed by prioritizing work items associated with synchronization operations so that resources on the endpoint are not excessively consumed which could reduce the quality of the user experience.

Claims

1. An automated method for managing a user experience at an endpoint of a mesh network, the method comprising the steps of:

monitoring user activity at the endpoint of the mesh network, the mesh network supporting a cloud-based data sharing service through which one or more users may share data from user-designated resources, the data being synchronized across a plurality of endpoints on the mesh network;

establishing prioritization, responsively to the monitoring, for synchronization operations to be performed on the shared data; and

throttling the synchronization operations in accordance with the prioritization so that resources on the endpoint are consumed in a manner that optimizes the user experience.

2. The automated method of claim 1 in which the user-designated resources comprise files or folders.

3. The automated method of claim 1 including a further step of monitoring explicit API calls made by an application on an endpoint that indicate activity of a user with respect to a resource.

4. The automated method of claim 1 including a further step of inferring user activity by monitoring system processes being performed on an endpoint.

5. The automated method of claim 4 in which the system processes include at least one of file system operations or hard disk access.

6. The automated method of claim 1 in which the synchronization operations include at least one of scanning a file or a folder for changes, computing a hash, performing uploading or downloading of data, performing uploading or downloading of data feeds from the service, or loading or saving data to a database.

7. The automated method of claim 1 in which the throttling comprises at least one of delaying a hash computation, increasing prioritization of data fetching from a peer endpoint, or increasing prioritization of uploading pending local changes.

8. The automated method of claim 1 including the further steps of persisting historical user activity and using the persisted historical user activity to identify data having a likelihood of being needed by the one or more users.

9. The automated method of claim 8 including a further step of establishing prioritization using the persisted historical user activity.

10. The automated method of claim 8 in which the data is identified using statistical analysis.

11. A computer-readable medium containing instructions which, when executed by one or more processors disposed on an electronic device, implement a mesh operating environment runtime, comprising:

a synchronization throttling manager configured for monitoring user activity at an endpoint on a mesh network, the mesh network supporting a cloud-based data sharing service through which one or more users may share data from user-designated resources, the data being synchronized across a plurality of endpoints on the mesh network; and

a work item manager operatively coupled to the synchronization throttling manager and configured for assigning prioritization to work items associated with operations for synchronizing replicated data across a plurality of endpoints on the mesh network, the work items being processed in accordance with the prioritization.

12. The computer-readable medium of claim 11 in which the synchronization throttling manager and work item manager are each configured as components of a mesh operating environment runtime that is instantiated on each of the endpoints on the mesh network.

13. The computer-readable medium of claim 11 in which the work items are processed from a work item queue.

14. The computer-readable medium of claim 11 in which the synchronization throttling manager is further configured for tracking historical user activity.

15. The computer-readable medium of claim 11 in which the electronic device is selected from a group consisting of PCs, set-top boxes, game consoles, laptop computers, pocket PCs, PDAs, smart phones, mobile phones, portable media players, handheld game devices, ultra-mobile computers, or devices comprising a combination of features provided therefrom.

16. A method performed at least in part by a computer in a cloud-based data sharing service, the method comprising the steps of:

providing feed data to implement synchronization infrastructure among endpoints in a mesh network over which the cloud-based data sharing service is operated;

maintaining a virtual endpoint on the cloud-based data sharing service that is accessible by a user at a remote device; and

synchronizing data to and from the virtual endpoint using the infrastructure based upon a priority assignment made at one of the endpoints, the assignment based on user activity that is monitored by the endpoint.

17. The method of claim 16 in which the remote device accesses the virtual endpoint over the Internet.

18. The method of claim 16 in which the virtual endpoint supports a resource that is shareable with the endpoints, the resource being one of file, folder, or message.

19. The method of claim 16 in which the endpoint monitors the user activity using a mesh operating environment runtime.

20. The method of claim 16 in which the feed data is expressed using one of Atom, JSON, FeedSync, RSS, WB-XML, or POX.
