Description

ABSTRACT:
In the maintenance of a ring-type local area network, the physical number, physical addresses and connection sequence of nodes in the network can be readily made known without need of any management by system control personnel. To this end, a frame which can be discriminated only by the immediately succeeding station is used, and own addresses are successively set in an information field of the frame to convey the status of physical connection to the succeeding stations.
