Abstract
A communication bridge interconnecting two or more local area networks. Input buffers forward packet headers of received data packets through to a routing engine. The routing engine contains one or more routing tables each having a plurality of table locations containing table data in the form of station addresses and routing data. The table is accessed by applying a hashing algorithm to a received destination address contained in the data packet to determine the table location and then checking that the station address retrieved from the table location corresponds with the destination address in the received data packet.
