Abstract
A reliable streaming system increases reliability of live and on-demand streaming media events through a robust server architecture that allows fast failover and recovery in the event of network, hardware, or other failures. The system provides for failover of encoders, ingest servers, which receive encoded media data from encoders, and origin servers, which serve as the retrieval point of last resort for connecting clients. The system also provides a push proxy mechanism that allows one copy of data to feed redundant servers and pre-warm caches, saving on provisioned bandwidth. In addition, the system provides a distribution server role that allows content to be automatically syndicated to a region when needed. Thus, the reliable streaming system provides a streaming solution with no single point of failure and redundancy and fast failover built into the content network architecture.
