Abstract

An improved user experience at a local client computer that is coupled to one or more remote servers over a WAN is provided by an arrangement in which data and files that are likely to be needed by a user during a work session are identified through the application of one or more heuristics and then pre-fetched to be made available in advance of the session'"'"'s start. The pre-fetching of the data and files may be performed as the client computer goes through its startup or boot process. When the startup is completed and the desktop applications become ready for use, the data and files that the user needs to immediately begin work are already available at the local client computer.

Claims

1. A method for optimizing a user experience at a client computer in a branch subnet of a network that comprises the branch subnet and a hub subnet, the method comprising the steps of:

monitoring for a user activation event for a user at the client computer;

performing accounting services for the client computer to track user behavior by the user comprising tracking the user'"'"'s consumption of data resources; and

responsively to the user activation event, sending a notification to a WAN (wide area network) optimization device, the notification being arranged to trigger application of heuristics to identify data resources for the user based at least in part on the user'"'"'s tracked user behavior for pre-fetching from a centralized resource in the hub subnet, the pre-fetching being commenced by the WAN optimization device subsequent to the user activation event and during startup of the client computer.

2. The method of claim 1 in which the accounting services are incorporated as part of an AAA service.

3. The method of claim 1 in which the WAN optimization device comprises one of a WAFS (wide area file system) controller in the subnet, a WAFS controller that is used pair-wise with a corresponding WAFS controller that is located in network, or a non-client based optimization device.

4. The method of claim 1 in which the user activation event is indicative of an initiation of a login to the network or a work session on the client computer, or other event that is indicative of a user'"'"'s use of the client computer.

5. The method of claim 1 in which the centralized resources comprise a server selected from one of file server, mail server, or web server.

6. The method of claim 1 in which the heuristics identify data that a user of the client computer will likely need in which likelihood of the need is based on the tracked user behavior.

7. A method for pre-fetching data from a server in a hub subnet of an enterprise network for delivery to a client computer in a branch subnet, the branch subnet and hub subnet being communicatively coupled over a WAN (wide area network) link, the method comprising the steps of:

receiving a notification from an access control device in the branch subnet that indicates an initiation of a work session by a user on the client computer;

utilizing one or more heuristics to identify data for pre-fetching from the server, the heuristics being configured for applying user behavior comprising consumption of data resources by the user that is tracked by the access control device, and

commencing the pre-fetching subsequent to the initiation of the work session and during startup of the client computer before the work session begins.

8. The method of claim 7 including a further step of performing WAN optimization on transport of pre-fetched data over the WAN link.

9. The method of claim 8 in which the WAN optimization includes a technique selected from one of stateless data compression, stateful data compression, caching, protocol-specific optimization, policy-based routing, or quality of service methodology.

10. The method of claim 8 in which the WAN optimization is performed by a set of pair-wise deployed WAN optimization appliances.

11. The method of claim 7 including a further step of storing the one or more heuristics in a store associated with one of access control device or WAN optimization device.

12. The method of claim 7 in which the access control device is selected from one of AAA controller or network controller.

13. The method of claim 7 including a further step of completing the pre-fetching before applications become available on the client computer'"'"'s desktop after the startup.

14. The method of claim 7 in which the one or more heuristics pertain to at least one of recently edited file, files or folders on the server that are associated with the user, a home page designated by the user for a web browser, or an explicitly configured filename from a network administrator that is indicative of an application profile.

15. An electronic device, comprising:

a first controller configured to implement a functionality for tracking user behavior by a user, the first controller configured to track the user'"'"'s consumption of data resources at a client computer at a hub node in the network during a previous work session; and

the first controller configured to trigger utilization of one or more heuristics at a second controller to identify data resources for the user based at least in part on the user'"'"'s tracked user behavior for pre-fetching to the client computer upon initiation of a new work session from a server at a branch node in the network, the pre-fetching being commenced subsequent to the initiation of the new work session and during startup of the client computer.

16. The electronic device of claim 15, wherein the one or more heuristics pertain to a file that was edited during the previous work session.

17. The electronic device of claim 15, wherein the one or more heuristics pertain to directory information for a set of documents or for a folder that are mirrored on one or more nodes of the network.

18. The electronic device of claim 15, wherein the one or more heuristics pertain to a file name that is explicitly configured by an administrator of the network.

19. The electronic device of claim 18, wherein the explicitly configured filename comprises an application profile.

20. The electronic device of claim 15, wherein the one or more heuristics pertain to a home page of a web browser.
