Abstract

Methods, systems, and software for operating a data storage system of a content delivery node are provided herein. In one example, a method of operating a data storage system of a content delivery node is presented. The method includes receiving content data into a storage system, storing the content data in a first storage space, determining popular content data within the content data based on at least user requests for the content data, and storing the popular content data in a second storage space.

Claims

1. A method of operating a data storage system of a content delivery node, the method comprising:

receiving content into the data storage system;

transferring the content for storage in a first storage space;

determining portions of the content which exceed a popularity threshold based on at least end user requests of the content; and

transferring the portions of the content for storage in a second storage space.

2. The method of claim 1 wherein determining portions of the content which exceed a popularity threshold comprises removing from the first storage space a portion of the content which does not exceed the popularity threshold content.

3. The method of claim 1 wherein transferring the portions of the content for storage in a second storage space comprises one of retaining the portions in the first storage space and removing all content from the first storage space.

4. The method of claim 1 wherein determining portions of the content which exceed a popularity threshold comprises calculating a count of end user requests weighted according to the recentness of the end user requests.

5. The method of claim 1 wherein the popularity threshold comprises at least one of a count of end user requests for the content and a percentage of all end user requests that are for the content.

6. The method of claim 1 wherein determining portions of the content which exceed a popularity threshold comprises treating as unpopular content already residing in the second storage space.

7. The method of claim 1 wherein receiving content into the data storage system comprises receiving content that was dynamically generated by an origin server.

8. The method of claim 1 wherein the second storage space comprises at least one of a flash drive and a hard drive.

9. The method of claim 1 wherein the first storage space comprises a RAM.

10. The method of claim 1 wherein the content comprises a video.

11. A software apparatus comprising:

one or more computer readable storage media; and

program instructions stored on the one or more computer readable media and executable by a processing system to operate a data storage system of a content delivery node, wherein the program instructions, when executed by the processing system, direct the processing system to at least;

receive content into the data storage system;

transfer the content for storage in a first storage space;

determine portions of the content which exceed a popularity threshold based on at least end user requests of the content; and

transfer the portions of the content for storage in a second storage space.

12. The software apparatus of claim 11 wherein determining portions of the content which exceed a popularity threshold comprises removing from the first storage space a portion of the content which does not exceed the popularity threshold content.

13. The software apparatus of claim 11 wherein transferring the portions of the content for storage in a second storage space comprises one of retaining the portions in the first storage space and removing all content from the first storage space.

14. The software apparatus of claim 11 configured to determine portions of the content which exceed a popularity threshold comprising calculating a count of end user requests weighted according to the recentness of the end user requests.

15. The software apparatus of claim 11 wherein the popularity threshold comprises at least one of a count of end user requests for the content and a percentage of all end user requests that are for the content.

16. The software apparatus of claim 11 configured to determine portions of the content which exceed a popularity threshold comprising treating as unpopular content already residing in the second storage space.

17. The software apparatus of claim 11 configured to receive content into the data storage system comprising receiving content that was dynamically generated by an origin server.

18. The software apparatus of claim 11 wherein the popularity threshold comprises at least one of a flash drive and a hard drive.

19. The software apparatus of claim 11 wherein the first storage space comprises a RAM.

20. The software apparatus of claim 11 wherein the content comprises a video.
