1. An apparatus for Internet-Protocol based communications in a wireless network having a minimum available physical data rate, the apparatus comprising:

  • a network interface to receive a plurality of multicast data packets;

    a memory; and

    a processor for executing instructions stored in the memory to;

    identify a plurality of receiving nodes in the wireless network requesting data corresponding to the plurality of multicast data packets,convert the received plurality of multicast data packets into one or more unicast data packets,determine an effective unicast rate for said one or more unicast data packets, wherein the effective unicast rate corresponds to a combined rate for converting the plurality of multicast packets into one or more unicast packets and sending the one or more unicast packets to the receiving nodes,compare said effective unicast rate to said minimum available physical data rate,serially transmit said one or more unicast data packets, via the network interface, to said plurality of receiving nodes at said effective unicast rate, when said effective unicast rate is greater than said minimum available physical data rate, andserially transmit said one or more unicast data packets, via the network interface, to said plurality of receiving nodes at said minimum available physical data rate, when said effective unicast rate is less than or equal to said minimum available physical data rate, wherein said network interface is capable of transmitting and receiving both multicast data packets and unicast data packets.
