ABSTRACT:
In a network environment such as a wireless packet network, a source node transmits a data stream, e.g., a stream of media packets to a plurality of sink nodes, including the source node transmitting a first data stream of unicast packets addressed to at least a first one of the sink nodes, while other ones of said sink nodes receive while in promiscuous mode traffic on the network including the data stream. Individual ones of the other sink nodes, upon ascertaining that there are packets of the stream that were not received, transmit a re-transmission request to the source node so that the source node can take corrective action, and so all the sink nodes can receive the data stream, even though sent as unicast addressed to fewer than all the sink nodes.
