Abstract
A method for allocating the use of an optical light-trail includes calculating a bid at a first node in the light-trail with consideration for the criticality of the node's need to transmit particular traffic on the light-trail. The method also includes transmitting the calculated bid to one or more of the other nodes included in the light-trail. In addition, the method includes receiving an acknowledgment from one or more of the other nodes included in the light-trail, each acknowledgement indicating whether the transmitted bid is higher or lower than a bid calculated by the node from which the acknowledgment originates. The method also includes determining, based at least on the content of acknowledgements received, whether the transmitted bid is the highest bid.
