Dynamic Content Delivery Network Allocation System

摘要

Particular embodiments allow a content delivery service to dynamically adjust how the service allocates content delivery traffic to multiple content delivery networks (CDNs). In one embodiment, the content delivery service may service enough requests for media programs that multiple CDNs are used. This allows the content delivery service to allocate traffic to different CDNs. Instead of solely relying on the CDN to provide quality of service solutions, the content delivery service may configure client devices to send information to it that allows the content delivery service to analyze the media program playback quality of service. Then, the content delivery service can adjust the allocation for the CDNs if a problem is detected at a specific CDN.

1. A method comprising:
determining, by a content delivery service, an allocation for video traffic for a plurality of content delivery networks (CDNs), wherein each CDN is configured to deliver media programs for the content delivery service to client devices and the allocation is used by the content delivery service to allot the video traffic to the plurality of CDNs for sending media programs to client devices; receiving messages from a plurality of client devices in which the plurality of CDNs delivered media programs, wherein the messages include information regarding the playback of the media programs on the client devices; determining metrics for each CDN based on the information regarding the playback of the media programs; analyzing the metrics to determine when to change the allocation, wherein the metrics are associated with a time period; and changing the allocation for the plurality of CDNs based on the analyzing, wherein the change in the allocation allots a first CDN in the plurality of CDN less video traffic to deliver for the content delivery service and a second CDN in the plurality of CDNs more video traffic to deliver for the content delivery service.
