Abstract

Methods and systems for selecting media service providers based on static resource information are described. A type of service to be performed on an item of content is identified. The item of content is identified during a session with a client device. A service provider is selected from a plurality of service providers. The selection is based on static service provider and static network information. The selection of a service provider is further based on service session information if the service session information has been received. Information is provided for transferring the session to the selected service provider. The selected service provider performs the service on the item of content.

providing information for transferring said session to said service provider, wherein said service provider performs said service on said item of content.

5. A method of selecting a media service provider for streaming media based on static resource information, said method comprising:

identifying a type of service to be performed on an item of streaming content,

wherein said item of streaming content is identified during a session with a client device;

selecting a service provider from a plurality of service providers based on static service provider information and static network information, said selecting of a service provider further based on service session information if said service session information has been received; and

providing information for transferring said session to said service provider, wherein said service provider performs said service on said item of streaming content.

6. The method of claim 5 wherein said static service provider and network information is accessible by a service location manager.

7. The method of claim 6 wherein said static service provider and network information comprises information concerning computational and memory resources, connectivity and expected bandwidth and latency between servers, client and content addresses, session dispatch history, network proximity and the identity of special purpose hardware.

8. The method of claim 7 wherein said special purpose hardware comprises encryption and compression hardware.

9. The method of claim 5 wherein said service session information comprises service session initiation and termination information.

10. The method of claim 9 wherein said initiation and termination information provides information regarding the computational resources used in previous sessions.

11. The method of claim 6 wherein said session dispatch history comprises information concerning content length.

12. The method of claim 5 wherein said streaming content is serviced and delivered to a client device as it is received.

13. The method of claim 12 wherein non streamed content is generated from said streaming content by said service provider.

14. The method of claim 13 wherein said streaming content is serviced by said service provider and delivered to a client device as a non streamed file.

15. A system for providing streaming media content to a client device, said system comprising:
