Abstract
A token-passing, ring-based data communications network provides a distributive method and apparatus for detecting and regenerating a lost token. The method includes, after detection of the loss of the token, transmitting at a detecting node a data packet not including a token, the data packet uniquely identifying the transmitting node as the data source. Simultaneously, the transmitting node, after transmitting the tokenless data packet, strips all incoming data from the network. If the transmitted packet is successfully received by the transmitting node, a new token is generated by the node. If the packet is not received, the node defers to an arbitration method which includes delaying a next data packet transmission for a probabilistically determined period of time. The mean time upon which the probabilistic approach is based increases with each unsuccessful data packet transmission attempt.
