Abstract

The invention includes a method for delivering rich media content, including audio and/or video content, to a user in a client-server network by using the most advantageous source and protocol of the available sources and protocols. A rich media application at a client computer receives a global media policy file that contains one or more media policy file entries, and each media policy file entry identifies one server computer and a protocol associated with the one server computer. The rich media application sends one or more connection requests to the servers identified in the global media policy using the protocol associated with each server. A data connection for delivering rich media content is established with the first server computer to respond to the connection request.

Claims

1. A method for establishing a data connection between a client computer and a server computer, the client computer configured to be coupled to one or more server computers via a computer network, the method comprising:

receiving, at the client computer, a media policy file, wherein the media policy file contains one or more media policy file entries, and wherein each media policy file entry identifies one server computer and a protocol associated with the one server computer;

sending, from the client computer, one or more connection requests, wherein each connection request is sent to one server computer identified in one media policy file entry using the protocol associated with the one server computer; and

establishing a data connection between the client computer and the first of the one or more server computers that responds to the connection request.

2. The method of claim 1, wherein each media policy file entry further includes an associated delay period and each connection request is sent only after the associated delay period expires.

3. The method of claim 2, wherein the delay period is measured from a time when the media policy file is received at the client computer.

4. The method of claim 1, wherein each media policy file entry further includes an associated timeout period and each connection request is abandoned after the timeout period expires.

5. The method of claim 4, wherein the timeout period is measured from a transmitting time of the connection request.

6. The method of claim 1, wherein each media policy file entry further includes a port identifier associated with the one server computer.

7. The method of claim 1, further comprising:

receiving, at the client computer, audio or video data, where the audio or video data is sent over the established data connection.

8. The method of claim 7, further comprising:

monitoring, at the client computer, the rate at which the audio or video data is sent over the established data connection.

9. The method of claim 1, further comprising:

monitoring, at the client computer, the established data connection; and

establishing a new data connection if the established data connection is terminated.

10. A computer-readable medium containing computer-readable instructions for establishing a data connection between a client computer and a server computer, the client computer configured to be coupled to one or more server computers via a computer network, the computer-readable instructions comprising:

computer-readable instructions for receiving, at the client computer, a media policy file, wherein the media policy file contains one or more media policy file entries, and wherein each media policy file entry identifies one server computer and a protocol associated with the one server computer;

computer-readable instructions for sending, from the client computer, one or more connection requests, wherein each connection request is sent to one server computer identified in one media policy file entry using the protocol associated with the one server computer; and

computer-readable instructions for establishing a data connection between the client computer and the first of the one or more server computers that responds to the connection request.

11. The computer-readable instructions of claim 10, wherein each media policy file entry further includes an associated delay period and each connection request is sent only after the associated delay period expires.

12. The computer readable instructions of claim 11, wherein the delay period is measured from a time when the media policy file is received at the client computer.

13. The computer-readable instructions of claim 10, wherein each media policy file entry further includes an associated timeout period and each connection request is abandoned after the timeout period expires.

14. The computer-readable instructions of claim 13, wherein the timeout period is measured from a transmitting time of the connection request.

15. The computer-readable instructions of claim 10, wherein each media policy file entry further includes a port identifier associated with the one server computer.

16. The computer-readable instructions of claim 10, further comprising:

computer-readable instructions for receiving, at the client computer, audio or video data, where the audio or video data is sent over the established data connection.

17. The computer-readable instructions of claim 10, further comprising:

computer-readable instructions for monitoring, at the client computer, the rate at which the audio or video data is sent over the established data connection.

18. The computer-readable instructions of claim 10, further comprising:

computer-readable instructions for monitoring, at the client computer, the established data connection; and

computer-readable instructions for establishing a new data connection if the established data connection is terminated.

19. A system comprising:

a client computer having computer-executable instructions for

receiving a media policy file, wherein the media policy file contains one or more media policy file entries, and wherein each media policy file entry identifies one server computer and a protocol associated with the one server computer, and

sending one or more connection requests, wherein each connection request is sent to one server computer identified in one media policy file entry using the protocol associated with the one server computer; and

a server computer having computer-executable instructions for

receiving the connection request from the client computer, and

responding to the connection request to establish a data connection with the client computer using the associated protocol.

20. The system of claim 19, where the client computer further includes computer-executable instructions for

receiving audio or video data from the server computer over the established data connection.

21. The system of claim 20, where the client computer further includes computer-executable instructions for

monitoring, at the client computer, the established data connection, and

computer-executable instructions for establishing a new data connection if the established data connection is terminated.
