Abstract
A method and apparatus for providing seamless failover to a redundant stream at an edge device is disclosed. A plurality of identical streams are received via a plurality of paths at a plurality of synchronization buffers. Each synchronization buffer receives one of the plurality of identical streams from a corresponding path of the plurality of paths. The plurality of streams are synchronized. A composite stream is generated from the plurality of identical streams according to a packet selection process.
