Abstract

A local application streaming proxy can create a virtual image of storage media, which allows cloud operators to rapidly deliver applications, or deliver any operating system remotely, while providing better security, network utilization, low power requirements, and consistent performance for streamed applications and operating systems. A station using its WiFi/LAN provides QoS guarantees (or priority) for application streaming network communications to create a consistent user experience regardless of other application bandwidth utilization. “HTTP demand paging” is also possible.

Claims

1. A method comprising:

obtaining an application snapshot at an application streaming proxy server;

obtaining portions of a streamified application at the application streaming proxy;

providing the application snapshot to a local application streaming client, wherein the application snapshot enables the local application streaming client to request file resources that are not on the local application streaming client;

streaming the portions of the streamified application to the local application streaming client.

2. The method of claim 1, further comprising:

obtaining an access control token at the application streaming proxy server;

streaming the portions of the streamified application in accordance with the access control token.

3. The method of claim 1, wherein the application streaming proxy server obtains the application snapshot from an application snapshot server.

4. The method of claim 1, wherein the application snapshot includes a predicted difference between an operating environment at the local application streaming client and an operating environment that would be at the local streaming client if the streamified application were installed at the local application streaming client.

5. The method of claim 1, wherein the application streaming proxy server obtains the portions of the streamified application from a master application streaming server.

6. The method of claim 1, further comprising obtaining the portions of the streamified application from an application streaming server over a 3G/4G network.

7. The method of claim 1, further comprising uploading a jumpstart portion of the streamified application to the local application streaming client, wherein the jumpastart portion enables the local application streaming client to begin executing the streamified application.

8. The method of claim 1, further comprising streaming a prefetch portion of the streamified application to the local application streaming client, wherein the prefetch portion is predicted to be needed at some point in the execution of the streamified application.

9. The method of claim 1, further comprising streaming the portions of the streamified application to the local application streaming over a wireless local area network.

10. The method of claim 1, further comprising:

providing requested portions of the streamified application to the local application streaming client when the requested portions are available at the local application streaming proxy;

forwarding the request for the requested portions from a master application streaming server when the requested portions are unavailable at the local application streaming proxy.

11. A system comprising:

a means for obtaining an application snapshot at an application streaming proxy server;

a means for obtaining portions of a streamified application at the application streaming proxy;

a means for providing the application snapshot to a local application streaming client, wherein the application snapshot enables the local application streaming client to request file resources that are not on the local application streaming client;

a means for streaming the portions of the streamified application to the local application streaming client.

12. A method comprising:

obtaining an access control token at the application streaming proxy server;

obtaining portions of a streamified application at the application streaming proxy;

streaming the portions of the streamified application to the local application streaming client in accordance with the access control token, wherein the application streaming proxy server uses the access control token to enforce access control policy at the application streaming client.

13. The method of claim 12, wherein the application streaming proxy server is operable in an offline mode in which the application streaming proxy server continues to enforce the access control policy while unconnected from a master application streaming server.

14. The method of claim 12, wherein the application streaming proxy server obtains the access control token from an access control server.

15. The method of claim 12, wherein the application streaming proxy server obtains the portions of the streamified application from a master application streaming server.

16. The method of claim 12, further comprising obtaining the portions of the streamified application from an application streaming server over a 3G/4G network.

17. The method of claim 12, further comprising uploading a jumpstart portion of the streamified application to the local application streaming client, wherein the jumpastart portion enables the local application streaming client to begin executing the streamified application.

18. The method of claim 12, further comprising streaming a prefetch portion of the streamified application to the local application streaming client, wherein the prefetch portion is predicted to be needed at some point in the execution of the streamified application.

19. The method of claim 12, further comprising streaming the portions of the streamified application to the local application streaming over a wireless local area network.

20. The method of claim 12, further comprising:

providing requested portions of the streamified application to the local application streaming client when the requested portions are available at the local application streaming proxy;

forwarding the request for the requested portions from a master application streaming server when the requested portions are unavailable at the local application streaming proxy.

21. A system comprising:

a means for obtaining an access control token at the application streaming proxy server;

a means for obtaining portions of a streamified application at the application streaming proxy;

a means for streaming the portions of the streamified application to the local application streaming client in accordance with the access control token, wherein the application streaming proxy server uses the access control token to enforce access control policy at the application streaming client.
