Abstract
In a data network, a source node transmits a data packet to a destination node across interconnected switches whereby a switch, upon receiving the data packet from the source node, queries other switches in the network for the appropriate switch and port on the switch out which to forward the data packet to the destination node. The appropriate switch responds to the query with its switch number and the port number of the port out which the data packet should be sent to reach the destination node. The querying switch caches the switch number and port number and prepends a destination tag to subsequent data packets it receives which are destined to the same destination node, thereby providing a distributed system among the switches in the network for maintaining detailed information regarding the appropriate switch and port out which to forward data packets received by a source node in the network.
