Stream control failover utilizing the sharing of state information within a logical group of stream servers

A technique for streaming digital video content to multiple clients involves establishing a logical group of IP-connected stream servers, generating state information at multiple stream servers within the logical group, sharing the state information amongst stream servers in the logical group, and u...

description A technique for streaming digital video content to multiple clients involves establishing a logical group of IP-connected stream servers, generating state information at multiple stream servers within the logical group, sharing the state information amongst stream servers in the logical group, and using the shared state information to respond to resource failures within the logical group. By sharing state information within the logical group of stream servers, stream servers with the shared state information can quickly take over the active streams from a failed stream server within the logical group. The quick transition of responsibility from one stream server to another enables the streaming network to provide continuous streaming of digital video content to the viewer without interruption.
