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:

generating, at an application streaming server, an application snapshot of a streamified application, comprising;

generating a pre-installation application environment snapshot of the streamified application;

generating a post-installation application environment snapshot of the streamified application;

comparing the pre-installation application environment snapshot with the post-installation application environment snapshot to generate the application snapshot of the streamified application;

sending the application snapshot of the streamified application to a local application streaming proxy server;

receiving, at the application streaming server from the local application streaming proxy server, requests for at least one portion of the streamified application according to the application snapshot of the streamified application for execution of the streamified application on a client coupled to the local application streaming proxy server;

sending to the local application streaming proxy server the at least one portion of the streamified application;

generating, at the application streaming server, access control tokens for the client; and

sending the access control tokens to the local application streaming proxy server, the access control tokens used to control access to the streamified application by the client at the local application streaming proxy server.

2. The method of claim 1, wherein the application snapshot includes at least one image of a snapshot of the streamified application executing on top of a machine.

3. The method of claim 1, wherein the access control tokens include digital rights management functionality.

4. The method of claim 1, further comprising:

sending either or both a prefetch portion and a jumpstart portion of the streamified application directly to the client by bypassing the local application streaming proxy server.

5. The method of claim 4, wherein the jumpstart portion of the streamified application is used to begin execution of the streamified application at the client.

6. The method of claim 1, wherein the local application streaming proxy server is implemented on a same device as the client.

7. The method of claim 1, further comprising:

receiving, at the application streaming server, images of writes made at the client in executing the streamified application;

sending additional portions of the streamified application to the local application streaming proxy server according to the images of the writes.

8. A system comprising:

an application streaming server configured to;

generate an application snapshot of a streamified application, the application streaming server further configured to;

generate a pre-installation application environment snapshot of the streamified application;

generate a post-installation application environment snapshot of the streamified application;

compare the pre-installation application environment snapshot with the post-installation application environment snapshot to generate the application snapshot of the streamified application;

send the application snapshot of the streamified application to a local application streaming proxy server;

a demand paging engine configured to;

receive from the local application streaming proxy server, requests for at least one portion of the streamified application according to the application snapshot of the streamified application for execution of the streamified application on a client coupled to the local application streaming proxy server;

send to the local application streaming proxy server the at least one portion of the streamified application; and

an access control token definition engine configured to;

generate access control tokens for the client;

send the access control tokens to the local application streaming proxy server, the access control tokens used to control access to the streamified application by the client at the local application streaming proxy server.

9. The system of claim 8, wherein the application snapshot includes at least one image of a snapshot of the streamified application executing on top of a machine.

10. The system of claim 8, wherein the access control tokens include digital rights management functionality.

11. The system of claim 8, wherein the demand paging engine is further configured to send either or both a prefetch portion and a jumpstart portion of the streamified application directly to the client by bypassing the local application streaming proxy server.

12. The system of claim 11, wherein the jumpstart portion of the streamified application is used to begin execution of the streamified application at the client.

13. The system of claim 8, wherein the local application streaming proxy server is implemented on a same device as the client.

14. The system of claim 8, wherein the demand paging engine is further configured to:

receive images of writes made at the client in executing the streamified application;

sending additional portions of the streamified application to the local application streaming proxy server according to the images of the writes.

15. A system comprising:

at least one processor configured to execute computer executable instructions stored in at least one memory to perform a method comprising;

generating, at an application streaming server, an application snapshot of a streamified application, comprising;

generating a pre-installation application environment snapshot of the streamified application;

generating a post-installation application environment snapshot of the streamified application;

comparing the pre-installation application environment snapshot with the post-installation application environment snapshot to generate the application snapshot of the streamified application;

sending the application snapshot of the streamified application to a local application streaming proxy server;

receiving, at the application streaming server from the local application streaming proxy server, requests for at least one portion of the streamified application according to the application snapshot of the streamified application for execution of the streamified application on a client coupled to the local application streaming proxy server;

sending to the local application streaming proxy server the at least one portion of the streamified application;

generating, at the application streaming server, access control tokens for the client; and

sending the access control tokens to the local application streaming proxy server, the access control tokens used to control access to the streamified application by the client at the local application streaming proxy server.

16. The system of claim 15, wherein the method further comprises sending either or both a prefetch portion and a jumpstart portion of the streamified application directly to the client by bypassing the local application streaming proxy server.

17. The system of claim 15, wherein the method further comprises:

receiving, at the application streaming server, images of writes made at the client in executing the streamified application;

sending additional portions of the streamified application to the local application streaming proxy server according to the images of the writes.
