Abstract
A message is generated at each of a plurality of source nodes, each message comprising at least address information identifying a first or destination node Di, and address information identifying a source node Si. The address information for the destination node is then used to route each message through the nodes of the communication network toward its destination node. At each node where two messages meet that are addressed to the same destination node, a second two messages are generated in place of the first two messages. One of these messages is routed toward the destination node while the other is routed toward an auxiliary node Ai whose address is specified in the message. If any further collisions take place between two messages routed to the same destination node, again two more messages are generated in place of the two colliding messages and one is routed toward the destination node while the other is routed toward another auxiliary node. The messages routed to the auxiliary node contain address information sufficient to route a message from the destination node to all the source nodes that originally addressed it.
