ABSTRACT:
In one embodiment, a mechanism for transparent real-time media server fail-over with idle-state nodes is disclosed. In one embodiment, a method includes replicating a start time of a request related to a bidirectional stream of media sent to an original master media server, receiving notification of selection as a new master media server after failure of the original master media server, determining an offset time by subtracting the replicated request start time from a current time, and resuming playback of the request at the offset time within the request.
