    • 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.
    • 可靠的流媒体系统通过强大的服务器架构提高实时和点播流媒体事件的可靠性,可在网络,硬件或其他故障情况下实现快速故障转移和恢复。 该系统提供编码器,摄像服务器,从编码器接收编码的媒体数据和原始服务器的故障转移,作为连接客户端的最后手段的检索点。 该系统还提供了一种推送代理机制,允许一个数据副本提供冗余服务器和预热缓存,从而节省提供的带宽。 此外,系统还提供了分发服务器角色,允许内容在需要时自动聚合到某个区域。 因此,可靠的流系统提供了一种流式解决方案,没有单点故障和冗余,并且快速故障切换内置于内容网络架构中。
