Abstract

A data access request from an application for access to a data resource is received from a first application. The data access request is analyzed to identify application-specific behavior indicating a type of data access for the data resource. The WAN acceleration functionality of a first device is configured for network traffic optimization based on the type of data access for the data resource. The analysis of the data access request may be based on attributes of the data access request, the data resource, and/or an access control restriction. The network traffic optimization may be adapted to optimize network traffic to a first portion of the data resource that is different than a second portion of the data resource associated with the data access request or to a second data resource separate from the data resource associated with the data access request.

Claims

1. A method of accelerating data access over a wide-area network, the method comprising:

receiving a data access request from an application for access to a data resource;

analyzing the data access request to identify application-specific behavior indicating a type of data access for the data resource;

selecting a network traffic optimization based on the type of data access for the data resource; and

configuring WAN acceleration functionality of a first device based on the type of data access for the data resource.

2. The method of claim 1, wherein analyzing the type of data access comprises:

evaluating an attribute of the data access request.

3. The method of claim 2, wherein the attribute of the data access request is selected from a group consisting of:

a type of access request, a source network location of the access request, a destination network location of the access request, and protocol parameters associated with the data access request.

4. The method of claim 1, wherein analyzing the type of data access comprises:

evaluating an attribute of the data resource.

5. The method of claim 4, wherein the attribute of the data resource is selected from a group consisting of:

contents of the data resource, a name of the data resource, a location of the data resource, an extension associated with the data resource, metadata associated with the data resource, a characteristic derived from the data resource, and a structure of the data resource.

6. The method of claim 1, wherein analyzing the type of data access comprises:

evaluating an attribute of an access control restriction associated with the data resource.

7. The method of claim 6, wherein the attribute of the access control restriction is selected from a group consisting of:

a type of access control restriction, a protocol associated with the access control restriction, a data resource offset or address associated with the access control restriction, and a size or range associated with the access control restriction.

8. The method of claim 1, wherein receiving the data access request from the application for access to the data resource comprises:

intercepting the data access request on route to a server.

9. The method of claim 1, wherein the network traffic optimization is adapted to prefetch and buffer a first portion of the data resource.

10. The method of claim 9, wherein the first portion of the data resource is different than a second portion of the data resource associated with the data access request.

11. The method of claim 10, wherein the second portion of the data resource is associated with an access control restriction and the first portion of the data resource is not associated with the access control restriction.

12. The method of claim 1 wherein the network traffic optimization is adapted to prefetch and buffer a first portion of a second data resource separate from the data resource associated with the data access request.

13. The method of claim 1, wherein the data access request is received by the first device.

14. The method of claim 1, wherein the data access request is received by a second device, wherein configuring WAN acceleration functionality of the device comprises:

communicating the network traffic optimization from the second device to the device.

15. The method of claim 1, comprising:

receiving a second data access request for access to the data resource;

determining if the second data access request is consistent with the application-specific behavior; and

modifying the second data access request in response to the determination that the second data access request is inconsistent with the application-specific behavior.

16. The method of claim 15, wherein the second data access request is received from a second application.

17. The method of claim 15, wherein the second data access request is received from the application.

18. The method of claim 15, comprising:

selecting a default network traffic optimization in response to the determination that the second data access request is inconsistent with the application-specific behavior; and

configuring the WAN acceleration functionality of the first device to the default network traffic optimization.

19. The method of claim 1, wherein analyzing the data access request to identify application-specific behavior indicating a type of data access for the data resource comprises:

comparing the data access request with at least one criteria from an application identification and optimization rule set.

20. The method of claim 17, wherein the application identification and optimization rule set includes function parameters.

21. The method of claim 1, wherein the data resource is includes a file.

22. The method of claim 1, wherein the data resource is includes file data.
