  • the source node transmitting a first stream of unicast packets addressed to at least one of the sink nodes, such that the addressee sink nodes can reliably receive the first stream while the other non-addressee sink nodes operate in promiscuous mode in which each can receive all traffic on the network including the first stream;

    receiving a re-transmission request packet from a particular non-addressee sink node with an indication that the particular non-addressee sink node has not successfully received one or more particular packets of the first stream; and

    taking action to ensure that the particular non-addressee sink node receives the one or more particular packets, such that all sink nodes can receive the complete first stream.
