Abstract
A device for interconnecting Local Area Networks (LANs) includes ports for attaching LAN segments and port modules for connecting the ports to a switch fabric. Each of the port modules include a mechanism which searches the Routing Information (RI) field of a Received frame to detect at least two Triplets (a minimum configuration for a LAN segment) indicating a Source path from an originator user and a Destination path to a destination user. The Triplet (single or in combination) is used to access a database (tables) which identifies the Port of Exit (POE) through which the frame is to be routed.
