Abstract
Methods, systems and data structures for determining a token master on a ring network are provided. According to one embodiment, determining a token master on a ring network includes receiving a packet containing a network token at a first node on the network. If the network token does not arrive within a preselected timeout period, generating an arbitration token. If the packet contains an arbitration token, determining if the arbitration token was modified by a higher priority node of the network and if not, setting the first node as a token master and converting the arbitration token to a packet transmission token. Arbitration tokens are used to identify a token master that is responsible for generating a packet transmission token onto the network, whereas the packet transmission token authorizes a transmitting node that has most recently received the packet transmission token to transmit locally generated packets onto the network.
