Abstract

The present invention is directed towards systems and methods for dynamically deploying and executing acceleration functionality on a client to improve the performance and delivery of remotely accessed applications. The acceleration program of the present invention is automatically installed and executed on a client in a manner transparent to and seamless with the operation of the client. An appliance may intercept a request of the client to establish a communication session or connection with a server, and transmit the acceleration program to the client. In some cases, the appliance determines whether the application being accessed by the client can be accelerated and only provides the acceleration program if the application can be accelerated. Upon receipt of the acceleration program, the client automatically performs a silent installation of the acceleration program and executes the acceleration program upon completion of the installation.

Claims

1. A method to accelerate access by a client to a resource via a network, the method comprising:

(a) receiving, by a client responsive to a request to access a resource via a network, an acceleration program to accelerate the access;

(b) silently installing, automatically by the client upon receipt, the acceleration program on the client;

(c) executing, automatically by the client upon installation, the acceleration program at a protocol layer of a network stack of the client; and

(d) performing, by the acceleration program at a single location in the network stack, a plurality of acceleration techniques on a network packet intercepted by the agent.

2. The method of claim 1, wherein step (a) further comprises receiving, by the client, the acceleration program upon establishment of a communication session with a device intermediary to the client and one or more servers.

3. The method of claim 1, wherein step (b) further comprises installing the acceleration program without interaction by a user of the client.

4. The method of claim 1, wherein step (b) further comprises installing a network driver of the acceleration program.

5. The method of claim 1, wherein step (b) further comprises installing the acceleration program at a network layer of the network stack.

6. The method of claim 1, wherein step (b) further comprises installing the acceleration program at a transport layer of the network stack.

7. The method of claim 1, wherein step (c) further comprises executing the acceleration program at a network layer of the network stack.

8. The method of claim 1, wherein step (c) further comprises executing the acceleration program at a transport layer of the network stack.

9. The method of claim 1, wherein step (d) further comprises performing, by the acceleration program, the plurality of acceleration techniques during a single execution of processing the network packet.

10. The method of claim 1, wherein step (d) further comprises performing, by the acceleration program, the plurality of acceleration techniques at a single interface point at which the network packet is intercepted.

11. A method for a device intermediary to a client and one or more servers to provide an acceleration program to a client for accelerating the client'"'"'s access to the one or more servers, the method comprising:

(a) receiving, by a device intermediary to a client and one or more servers, a request from the client to access the server via a network;

(b) determining, by the device, to accelerate the client'"'"'s access;

(c) obtaining, by the device responsive to the determination, an acceleration program, the acceleration program constructed to execute a plurality of acceleration techniques at a single location in a protocol layer of a network stack of the client; and

(d) transmitting, by the device responsive to the request, the acceleration program to the client for silent installation.

12. The method of claim 11, wherein step (a) further comprises receiving, by the device, the request from the client to establish a session with the server.

13. The method of claim 11, wherein step (a) further comprises receiving, by the device, the request from the client to access an application.

14. The method of claim 11, wherein step (b) further comprises determining, by the device, to accelerate the client'"'"'s access based on performance of the client.

15. The method of claim 11, wherein step (b) further comprises determining, by the device, to accelerate the client'"'"'s access based on a type of protocol used for accessing the server.

16. The method of claim 11, wherein step (b) further comprises determining, by the device, to accelerate the client'"'"'s access based on a type of application to be accessed via the server.

17. The method of claim 11, wherein step (c) further comprises obtaining, by the device, the acceleration program further constructed to be automatically installed by the client upon receipt and automatically executed upon installation.

18. The method of claim 11, wherein step (c) further comprises obtaining, by the device, the acceleration program via one of storage or memory of the device.

19. The method of claim 11, wherein step (c) further comprises obtaining, by the device, the acceleration program from a second device via a network.

20. The method of claim 11, wherein step (d) further comprises transmitting, by the device, the acceleration program, via a transport layer connection established with a second program on the client.
