ABSTRACT:
A method and apparatus for associating stations to a port on a network concentrator. The network concentrator implements a network having a Ring based topology. Associating stations to ports provides for the coupling of multiple stations to a single port. Three maps are created which describe the network, a port map, a station map and an exit station map. The port map identifies the ports having one or more stations coupled to it. The station map identifies each station in the network. The exit station map identifies for each port with a station coupled to it, the station which transmits data into the port. By identifying the stations between two exit stations on adjacent ports in the network concentrator, the stations coupled to a port are determined. The identification of exit stations is facilitated by the use of an exit station detection circuit located at the port.
