Abstract:
Methods are provided for determining a master node on a ring network. According to one embodiment, a first node on the ring network initiates circulation of an arbitration token by (i) determining an arbitration token timeout period has elapsed and (ii) transmitting the arbitration token to a neighboring node. Upon receipt of the arbitration token by a node, it determines its relative priority by comparing its ID to an ID field of the arbitration token, initialized by the first node. If the node is determined to be higher priority, then it overwrites the ID field and retransmits the arbitration token onto the ring network. If the node is determined to be lower priority, then the node retransmits the arbitration token without overwriting the ID field. If the node is determined to be of equal priority and the node is the first node, then it assumes the master node role.
