1. A method for constructing a data packet having both a payload segment that carries data associated with a link layer (MAC) or network layer (IP) address and a header segment that has one or more fields, the method comprising:

  • generating an address value based on the network layer address or link layer address at a transmitting terminal;

    formatting the address value; and

    populating the formatted address value into a field of the header that will be used as a selection criteria by a receiving terminal, wherein the selection criteria is established without the use of tables used to link a packet identification to a multicast network layer address.
