1. A method for overriding packet acceptance criteria established at each individual connection of a network node, to provide a collective packet acceptance criteria for each packet of a multicast transmission targeted for the individual connections, comprising:

  • collecting the packet acceptance criteria from each of the individual connections in the network node that are targeted for the multicast transmission;

    calculating a multicast packet priority for each of the packets associated with the multicast transmission based on an aggregate analysis of the packet acceptance criteria of each of the individual connections;

    collectively accepting or discarding each of the packets associated with the multicast transmission based on the calculated multicast packet priority; and

    determining whether the packet is a packet associated with a multicast transmission, and bypassing the collecting of the packet acceptance criteria, bypassing the calculating of a multicast packet priority, and bypassing the collective accepting or discarding of each of the packets when the packet is not associated with the multicast transmission.
