Abstract:

Multiple segmentation servers are synchronized to provide failover capacity in such a way that should a failover occur, the segment numbers/playlists/encryption keys/decryption keys are identical on each of the segmentation servers. Synchronizing the contents of a segmentation server on one or more backup segmentation servers ensures that the delivery of a content stream is immune to the failure of segmentation servers, provided at least one segmentation server remains fault-free. A caching server may further facilitate the fault tolerance by checking the availability of the individual segmentation servers, collect content segments from one of the segmentation servers, and serve the content segment to clients. The caching server automatically checks a primary segmentation server to ensure it is available (e.g., online), and provides automatic failover to a backup segmentation server should the primary server experience a fault (e.g., go offline).
