摘要：
A local area network with a plurality of nodes for transmitting cells in the asynchronous transfer mode over a ring system having two opposite direction rings. In the event of a defect in a transmitting line from a node, or a defect in a neighboring node, a loop is formed in this node to reroute messages from one ring to the other. First, a node detecting a defect transmits a message of a first type to all other involved nodes, identifying the location of the detected defect. This information is entered in a respective status table in each node. After evaluating the information in its status table, a node which should form a loop does so, and sends a message of a second type identifying the loop to any nodes which do not already have this information.
