Abstract
A method is provided for managing over-the-top delivery of content through a plurality of content delivery networks (CDN). The method provided works transparently with standard HTTP servers supporting an initial request for content from a client to a first preferred CDN. If the first CDN does not have the content, the method includes provisions for the first CDN to acquire the content from a second CDN, or for the client to request the content from a second CDN directly. A system is also specified for implementing a client and server infrastructure in accordance with the provisions of the method.
Claims10
A method of operating a client device for retrieving content from a content delivery system including a workflow manager and a plurality of content delivery networks, comprising:
- acquiring, from the workflow manager, a prioritized list of the content delivery networks from which desired content can be retrieved;
- selecting from the prioritized list an initial primary content delivery network and a backup content delivery network;
- initially issuing content requests to the initial primary content delivery network;
- and
- in the event that a content request issued to the initial primary content delivery network fails, selecting the backup content delivery network as a new primary content delivery network and issuing further content requests to the new primary content delivery network.
A client device, comprising:
- a least one processor;
- a non-transitory computer-readable storage medium coupled to the at least one processor, further comprising computer-readable instructions, when executed by the at least one processor, are configured to:
- acquire, from a workflow manager, a prioritized list of content delivery networks from which desired content can be retrieved;
- select from the prioritized list an initial primary content delivery network and a backup content delivery network;
- initially issue content requests to the initial primary content delivery network;
- and
- in the event that a content request issued to the initial primary content delivery network fails, select the backup content delivery network as a new primary content delivery network and issuing further content requests to the new primary content delivery network.
