  • a) receiving a packet sent by a sender to at least one receiver, the packet comprising a parameter relating to a multicast announce address;

    b) associating a forwarding rule set with the packet if the parameter has a defined value;

    c) using the forwarding rules set to determine if any of the at least one destination addresses associated with the multicast announce address corresponds to a receiver that has a receiver format that must be converted, where the forwarding rules set defines when a packet should be converted from a sender format to a receiver format before forwarding the packet;

    d) converting the packet from the sender format to the receiver format for each destination address identified in step (c)(b) as requiring conversion;

    e) forwarding the packet in accordance with the forwarding rules set; and
