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:

receiving, at a local application streaming proxy server, an application snapshot of a streamified application;

sending a request for a portion of the streamified application based on the application snapshot from the local application streaming proxy server to an application streaming server;

receiving at the location application streaming proxy server from the application streaming server the portion of the streamified application;

receiving at the local application streaming proxy server from the application streaming server access control tokens for a client, the access tokens used to control access for the client to the streamified application by the local application streaming proxy server;

receiving a request for the portion of the streamified application at the local application streaming proxy server from the client;

providing the client with access to the portion of the streamified application in accordance with the access control tokens;

sending from the local application streaming proxy server to the client jumpstart partials of the streamified application without receiving requests for the jumpstart partials;

sending from the local application streaming proxy server to the application streaming server images of writes made at the client in executing the streamified application; and

receiving at the local application streaming proxy sever from the application streaming server additional portions of the streamified application according to the images of the writes.

2. The method of claim 1, further comprising:

generating, at the application streaming server, a pre-installation application environment snapshot of the streamified application;

generating, at the application streaming server, a post-installation application environment snapshot of the streamified application;

comparing, at the application streaming server, the pre-installation application environment snapshot with the post-installation application environment snapshot to generate the application snapshot of the streamified application.

3. The method of claim 1, further comprising generating, at the application streaming server, the access control tokens.

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

5. The method of claim 1, further comprising:

receiving at the local application streaming proxy server from the client requests for prefetched portions of the streamified application;

sending the prefetched portions of the streamified application to the client according to the access control tokens.

6. The method of claim 1, further comprising:

storing the portion of the streamified application in a cache of the client;

managing the cache of the client in accordance with a cache management protocol.

7. The method of claim 1, further comprising:

tethering a cloud storage virtual hard drive to the client;

using the cloud storage virtual hard drive to generate a preboot execution environment for use in beginning execution of the streamified application at the client.

8. The method of claim 1, further comprising providing the application snapshot to the client according to the access control tokens.

16. The system of claim 1, wherein the local application streaming proxy is further configured to provide the application snapshot to the client according to the access control tokens.

9. A system comprising:

an application streaming server configured to provide an application snapshot of a streamified application;

a local application streaming proxy server configured to;

receive the application snapshot of the streamified application;

send a request for a portion of the streamified application based on the application snapshot to the application streaming server;

receive from the application streaming server the portion of the streamified application;

receive from the application streaming server access control tokens for a client, the access control tokens used to control access for the client to the streamified application by the local application streaming proxy server;

receive a request for the portion of the streamified application from the client;

provide the client with access to the portion of the streamified application in accordance with the access control tokens;

send to the client jumpstart partials of the streamified application without receiving requests for the jumpstart partials;

send to the application streaming server images of writes made at the client in executing the streamified application; and

receiving from the application streaming server additional portions of the streamified application according to the images of the writes.

10. The system of claim 9, wherein the application streaming server is 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.

11. The system of claim 9, wherein the application streaming server is further configured to generate the access control tokens.

12. The system of claim 9, wherein the local application streaming proxy server is implemented on a same device as the client.

13. The system of claim 9, wherein the local application streaming proxy server is further configured to:

receive requests for prefetched portions of the streamified application from the client;

send the prefetched portions of the streamified application to the client according to the access control tokens.

14. The system of claim 9, further comprising a cache management engine at the client configured to:

store the portion of the streamified application in a cache of the client;

manage the cache of the client in accordance with a cache management protocol.

15. The system of claim 9, further comprising a bootstrap loader at the client configured to:

tether a cloud storage virtual hard drive to the client;

use the cloud storage virtual hard drive to generate a preboot execution environment for use in beginning execution of the streamified application at the client.
