Abstract
The present system includes logic circuitry to be connected between at least two networks. When a message is sent by a station in a first network, the destination part of the message will be examined by the logic circuitry to see if the destination address has been recorded (stored) and if so to what network the destination station belongs. If the destination address is located in the sending network, the message is not sent to the non-sending network. If the destination address is located in the non-sending network, the message will be sent thereto. If the destination address is not recorded, i.e., it represents a new station, the message will be sent to the non-sending network (such a message is automatically sent to its own network). In the latter case when such a new station becomes a source station, its address will be recorded so that the next time such a station is a destination, the system will know in which network it is located. Further the present system removes from its stored addresses those addresses which are seldom used.
