Abstract

A system for storing content available for streaming includes a storage tier with a plurality of storage clusters, each of the storage clusters having at least one server, the storage clusters collectively storing multiple media content files; a streaming tier coupled to the storage tier, the streaming tier having multiple streaming servers, the streaming tier being configured to stream data over a network faster than the storage tier is able to stream the data over the network; and a computer-implemented synchronization module configured to analyze traffic statistics associated with a media content file stored on the storage tier and selectively replicate the media content file on the streaming tier based on the traffic statistics.

Claims

1. A system for storing content available for streaming, the system comprising:

a storage tier comprising a plurality of storage clusters each of said storage clusters comprising at least one server, said storage clusters collectively storing a plurality of media content files;

a streaming tier communicatively connected to said storage tier, said streaming tier comprising a plurality of streaming servers, said streaming tier being configured to stream data over a network faster than said storage tier is able to stream said data over said network; and

a computer-implemented synchronization module configured to analyze traffic statistics associated with a said media content file stored on said storage tier and selectively replicate said media content file on said streaming tier based on said traffic statistics.

2. The system of claim 1, wherein said traffic statistics comprise a measured demand for said media content file.

3. The system of claim 1, wherein said traffic statistics comprise an anticipated demand for said media content file.

4. The system of claim 1, wherein said synchronization module replicates said media content file on said streaming tier in proportion to a demand for said media content file derived from said traffic statistics.

5. The system of claim 1, wherein said traffic statistics are measured by said streaming servers in said streaming tier.

6. The system of claim 5, wherein said traffic statistics comprise requests for said media content file tracked by a said streaming server.

7. The system of claim 6, wherein said traffic statistics comprise a number of times the said streaming server has successfully streamed said media content file to a requesting client.

8. The system of claim 6, wherein said traffic statistics comprise a number of times the said streaming server was unable to fulfill a request for said media content file from a client.

9. The system of claim 5, wherein said synchronization module comprises a listener subsystem configured to retrieve said traffic statistics measured by the said streaming server.

10. The system of claim 9, wherein said listener subsystem is configured to poll a storage location in said streaming server to retrieve said traffic statistics measured by the said streaming server.

11. The system of claim 10, wherein said listener subsystem is configured to poll said location of said recorded statistics after the expiration of a predefined period of time.

12. The system of claim 10, wherein said listener subsystem is configured to poll said location of said recorded statistics continually.

13. The system of claim 1, wherein said listener subsystem is configured to retrieve said traffic statistics from each of said streaming servers in said streaming tier.

14. The system of claim 1, wherein said synchronization module further comprises a collector module coupled to each of said streaming servers in said streaming tier, said collector module being configured to parse said traffic statistics as measured by each of said streaming servers and update a statistics database associated with said synchronization module with data representative of said traffic statistics measured by each of said streaming servers.

15. The system of claim 1, wherein said synchronization module is further configured to implement:

a cache table configured to track each media content file stored by a said streaming server together with traffic statistics associated with each said media content file stored by said streaming server; and

a cache manager module configured to continuously update said cache table.

16. The system of claim 1, wherein said synchronization module is further configured to remove said media content file from a said streaming server based on said traffic statistics associated with said media content file.

17. A data storage structure for storing media content available for streaming, said structure comprising:

said storage tier comprising a plurality of storage clusters each of said storage clusters comprising at least one server, said storage clusters collectively storing a plurality of media content files;

a streaming tier communicatively connected to said storage tier, said streaming tier comprising a plurality of streaming servers, each of said streaming servers being configured to store at least one said media content file stored by said storage tier and stream said media content file over a network at a rate that is faster than said storage tier is able to stream said media content file over said network, each of said streaming servers being further configured to record traffic statistics associated with said streaming of said at least one media content file; and

a computer-implemented synchronization module communicatively coupled to said streaming servers, said synchronization module being configured to analyze said traffic statistics recorded by said streaming servers and dynamically replicate media content files stored by said storage tier onto said streaming servers based on said traffic statistics.

18. The system of claim 17, wherein said synchronization module is further configured to remove media content files from at least one of said streaming servers based on said traffic statistics.

19. A method, comprising:

storing a plurality of media content files on a storage tier, said storage tier comprising a plurality of storage clusters, each of said storage cluster comprising at least one server;

storing at least one of said media content files on a streaming server of a streaming tier, said streaming server being able to stream said at least one of said media content files over a network at a rate faster than said storage tier is able to stream said at least one of said media content files over said network;

tracking streaming activity of said at least one of said media content files in said streaming server; and

selectively replicating said media content files on said streaming server based on said tracked streaming activity.

20. The method of claim 19, wherein said tracked streaming activity comprises a number of requests received at said streaming server for said at least one of said media content files.
