Abstract
A plurality of local networks each have one or more terminal sets and a message re-director. The message re-directors are adapted to communicate with each other across another network through edge devices. The message re-directors are also adapted to convert multicast messages received locally from the terminal sets into unicast messages for transmission across the other network. The unicast messages are received by the other message re-directors. Each one of the other message re-directors then multicasts information received as part of the multicast messages received to the terminal sets within its local network.
