Abstract

Access to content may be enabled by receiving an instruction indicating a client request to access content, accessing a list of content sources capable of rendering the content for which access is requested by the client, determining a performance metric for at least two of the content sources, and selecting among the content sources based on the performance metric to identify a content source to be accessed by the client.

Claims

1. A computer-implemented method for providing content to a client, the method comprising the following operations performed by at least one processor:

receiving, by the client, responses to a content request from a plurality of sources;

determining, by the client and based on the received responses, values of a performance metric for the sources, wherein determining values of the performance metric comprises determining a rate at which the client receives identical portions of the content from the sources;

selecting, by the client and based on the performance metric values, one of the sources;

retrieving, over a connection between the client and the selected source, first portions of the content;

monitoring, by the client, a value of the performance metric for a non-selected one of the sources;

transitioning, by the client based on the monitored value of the performance metric, to the non-selected one of the sources; and

retrieving, by the client over a connection between the client and the non-selected source, second portions of the content.

2. The method of claim 1, wherein the content comprises an audio or video stream.

3. The method of claim 1, wherein determining values of the performance metric comprises maintaining, by the client and based on the performance metric values, a relative performance list.

4. The method of claim 3, wherein maintaining a relative performance list comprises ranking, by the client and based on the performance metric values, at least two sources by determined values of the performance metric.

5. The method of claim 1, wherein the received identical portions comprise a subset of the content.

6. The method of claim 1, wherein determining values of the performance metric comprises beginning measurement of the performance metric once the content is received.

7. The method of claim 1, wherein determining values of the performance metric comprises beginning measurement of the performance metric upon expiration of a predetermined time period.

8. The method of claim 1, wherein the performance metric comprises one or more of a response time, a throughput rate, and a utilization rate.

9. A client for acquiring content from a plurality of sources, the client comprising:

a processor; and

a non-transitory computer-readable medium storing a set of instructions for execution by the processor to perform the following operations;

receiving a response to a content request from the plurality of sources;

determining, based on the received responses, values of a performance metric for the sources, wherein determining values of the performance metric comprises determining a rate at which the client receives identical portions of the content from the sources;

selecting, based on the performance metric values, one of the sources;

retrieving, over a connection between the client and the selected source, first portions of the content;

monitoring, a value of the performance metric for a non-selected one of the sources;

transitioning, based on the monitored value of the performance metric, to the non-selected one of the sources; and

retrieving, over a connection between the client and the non-selected source, second portions of the content.

10. The client of claim 9, wherein the content comprises an audio or video stream.

11. The client of claim 9, wherein determining values of the performance metric comprises maintaining, by the client and based on the performance metric values, a relative performance list.

12. The client of claim 11, wherein maintaining a relative performance list comprises ranking, by the client and based on the performance metric values, at least two sources by determined values of the performance metric.

13. The client of claim 9, wherein the received identical portions comprise a subset of the content.

14. The client of claim 9, wherein determining values of the performance metric comprises beginning measurement of the performance metric once the content is received.

15. The client of claim 9, wherein determining values of the performance metric comprises beginning measurement of the performance metric upon expiration of a predetermined time period.

16. The client of claim 9, wherein the performance metric comprises one or more of a response time, a throughput rate, and a utilization rate.

17. A client for acquiring content from a plurality of sources, the client comprising:

a processor; and

a non-transitory computer-readable medium storing a set of instructions for execution by the processor to perform the following operations;

receiving identical portions of requested content from each of the plurality of sources in response to a content request;

determining, based on the received responses, values of a performance metric for the sources, wherein determining values of the performance metric comprises determining a rate at which the client receives identical portions of the content from the sources;

selecting, based on the performance metric values, one of the sources;

retrieving, over a connection between the client and the selected source, first portions of the content;

requesting a status from one or more nonselected sources;

receiving responses to the status request from the one or more nonselected sources;

selecting, based on the responses to the status request, one of the nonselected sources; and

retrieving, over a connection between the client and the nonselected source, second portions of the content.

18. The client of claim 17, wherein the content comprises an audio or video stream.

19. The client of claim 17, the operations further comprising:

providing, after selection of one of the sources, disconnection requests to one or more nonselected sources.

20. The client of claim 17, the operations further comprising:

determining, before requesting the status from one or more nonselected sources, that an interrupt condition prevents content retrieval over the connection between the client and the selected source.

21. The client of claim 17, wherein the performance metric comprises one or more of a response time, a throughput rate, and a utilization rate.
