MULTICAST DATA PACKET RECOVERY SYSTEM

摘要

Particular embodiments of the disclosed subject matter provide methods and systems to support a multicast data packet recovery system. In an example embodiment, the system includes a distribution server operable to detect a missed data packet in a multicast data stream; issue a request for a retransmission of the missed data packet to an acquisition server via a unicast data channel; receive the requested data packet via a multicast data channel, in response to the request for a retransmission of the missed data packet; and send the requested data packet to one or more subscribers.
