Multi-CDN digital content streaming

1. A method, comprising:

retrieving network performance information for each content server included in a plurality of content servers;

assigning a different portion of a content buffer included within a content player to a different content server included in the plurality of content servers based on the network performance information by dividing the content buffer into a plurality of portions, and, for each portion, determining the size of the portion based on the network performance information retrieved for the content server associated with the portion; and

storing digital content received from each content server in the portion of the content buffer associated with the content server.

2. The method of claim 1 , wherein assigning a different portion of the content buffer comprises dividing the content buffer into a plurality of portions, and assigning a first content server with slower network performance, as indicated by the network performance information retrieved for the first content server, to a later portion of the content buffer, and assigning a second content server with faster network performance, as indicated by the network performance information retrieved for the second content server, to an earlier portion of the content buffer.

3. The method of claim 1 , wherein assigning a different portion of the content buffer further comprises assigning a first content server with slower network performance, as indicated by the network performance information retrieved for the first content sever, to a smaller portion of the content buffer, and assigning a second content server with faster network performance, as indicated by the network performance information retrieved for the second content server, to a larger portion of the content buffer.

4. The method of claim 1 , further comprising monitoring the network performance of a first content server while the first content server is transmitting digital content to the content player.

5. The method of claim 1 , wherein the network performance information specifies at least one of network throughput for a content server, network bandwidth for the content server, network throughput variance for the content server, average latency of the content server, historical availability of the content server, and services supported by the content server.

6. The method of claim 1 , wherein each content server included in the plurality of content servers comprises a virtualized computing system.

7. The method of claim 1 , wherein at least one content server included in the plurality of content servers comprises a virtualized computing system.

8. One or more non-transitory computer-readable media including instructions that, when executed by one or more processors, cause the one or more processors to perform the steps of:

retrieving network performance information for each content server included in a plurality of content servers;

assigning a different portion of a content buffer included within a content player to a different content server included in the plurality of content servers, wherein a size of each portion of the content buffer is based on the network performance information retrieved for a content server associated with the portion;

transmitting a different request to each content server included in the plurality of content servers to transmit digital content; and

for each content server included in the plurality of content servers, receiving the digital content associated with the portion of the content buffer associated with the content server.

9. The one or more non-transitory computer-readable media of claim 8 , wherein assigning a different portion of the content buffer comprises dividing the content buffer into a plurality of portions, and assigning a first content server with slower network performance, as indicated by the network performance information retrieved for the first content server, to a later portion of the content buffer, and assigning a second content server with faster network performance, as indicated by the network performance information retrieved for the second content server, to an earlier portion of the content buffer.

10. The one or more non-transitory computer-readable media of claim 8 , wherein assigning a different portion of the content buffer comprises dividing the content buffer into a plurality of portions.

11. The one or more non-transitory computer-readable media of claim 10 , wherein assigning a different portion of the content buffer further comprises assigning a first content server with slower network performance, as indicated by the network performance information retrieved for the first content sever, to a smaller portion of the content buffer, and assigning a second content server with faster network performance, as indicated by the network performance information retrieved for the second content server, to a larger portion of the content buffer.

12. The one or more non-transitory computer-readable media of claim 8 , wherein the network performance information specifies at least one of network throughput for a content server, network bandwidth for the content server, network throughput variance for the content server, average latency of the content server, historical availability of the content server, and services supported by the content server.

13. The one or more non-transitory computer-readable media of claim 8 , wherein each content server included in the plurality of content servers comprises a virtualized computing system.

14. A content player, comprising:

a memory storing a playback application and a content buffer; and

a processor coupled to the memory and, when executing the playback application, is configured to:

retrieve network performance information for each content server included in a plurality of content servers;

assign a different portion of the content buffer to a different content server included in the plurality of content servers based on the network performance information by dividing the content buffer into a plurality of portions, and, for each portion, determining the size of the portion based on the network performance information retrieved for the content server associated with the portion;

transmit a different request to each content server to transmit digital content associated with the portion of the content buffer associated with the content server; and

store the digital content received from each content server in the portion of the content buffer associated with the content server.

15. The content player of claim 14 , wherein each content server included in the plurality of content servers comprises a virtualized computing system.

16. The content player of claim 14 , wherein at least one content server included in the plurality of content servers comprises a virtualized computing system.

17. The content player of claim 14 , wherein the processor assigns a different portion of the content buffer by dividing the content buffer into a plurality of portions, and assigning a first content server with slower network performance, as indicated by the network performance information retrieved for the first content server, to a later portion of the content buffer, and assigning a second content server with faster network performance, as indicated by the network performance information retrieved for the second content server, to an earlier portion of the content buffer.

18. The content player of claim 17 , wherein the processor further assigns a different portion of the content buffer further by assigning a first content server with slower network performance, as indicated by the network performance information retrieved for the first content sever, to a smaller portion of the content buffer, and assigning a second content server with faster network performance, as indicated by the network performance information retrieved for the second content server, to a larger portion of the content buffer.
