Abstract
A method is provided in one example embodiment and it includes receiving a first plurality of packets from an active stream at an output device and communicating the first plurality of packets to a next destination. The method also includes receiving a second plurality of packets from a standby stream of the output device, the streams are sent by an input device. The method further includes performing a switchover at the output device such that the second plurality of packets is communicated to the next destination and the first plurality of packets is not. The switchover is triggered when a portion of the first plurality of the packets from the active stream is not received during a period of time that is greater than a majority of inter-arrival times of the second plurality of packets on the standby stream.
