ABSTRACT:
A method for multicast communication wherein a multicast message is distributed to all the nodes in a multicast range. If a multicast message has a multicast range which is larger than one link in the network then the message is forwarded along a unique set of pathways through the range. The unique set of pathways is called a multicast spanning tree and is unique to all nodes which can communicate directly by virtue of a list of known nodes. The network is divided into areas each of which contains a group of directly communicating nodes. A group of nodes designated as level two nodes facilitates communication between the nodes in different areas.
