Error recovery mechanism and network element comprising same

摘要

A method is provided for facilitating error recovery of media stream packets in an access node. The method comprises storing a plurality of data transmission units of a media stream in a buffer of an access node, receiving a request for retransmission of at least one designated data transmission unit for reception by a designated subscriber media decoder apparatus, accessing the at least one designated data transmission unit within the buffer in response to receiving the request for retransmission and transmitting the at least one designated data transmission unit from the access node for reception by the designated subscriber media decoder apparatus in response to successfully accessing the at least one designated data transmission unit.
