Abstract:
1. A method for simulating multicast connections receiving at a receiving communication node in a tree structure a request from a new communication node to join the tree structure, the tree structure comprising a plurality of communication nodes linked using unicast connections; and evaluating at the receiving communication node whether the receiving communication node has a greatest permitted number of child nodes connected thereto and whether the new communication node belongs to a same subnet as the receiving communication node and whether one of the child nodes connected to the receiving communication node does not belong to the same subnet as the receiving communication node, and, if so, connecting the new communication node to the receiving communication node and disconnecting the child node of the receiving communication node that does not belong to the same subnet as the receiving communication node, and, if not, transmitting a request to join the tree structure identifying the new communication node to the child node of the receiving communication node closest to the new communication node.
