Abstract:
A system for delivering packetized data in a network comprising a plurality of packet switch communities, wherein each of the packet switch communities has a plurality of endpoints connected to a common packet switch and having a unique address, and wherein each of the endpoints has addresses unique to their respective packet switch community. The endpoints in this system add a two-part destination address to the packetized data to be sent, wherein the first field represents a packet switch community and the second represents a destination endpoint. Each packet switch community is responsive to the first field being different from its own address for delivering the packetized data to a switch. The switch is responsive to the first field for delivering the packetized data to a packet switch community identified by the first field. Finally, each endpoint in the destination packet switch community is responsive to the first and second address fields for accepting packetized data.
