Recently, a new WDM optical network infrastructure named SMART, which is capable of dynamically setting up, modifying, and tearing down optical connections, was proposed. The performance of SMART is determined by the performance of its hyper-channels, which are essentially optical buses or light-trails. Previously proposed MAC protocols for unidirectional optical buses can be used as distributed medium access control protocols for hyper-channels. However, these protocols require optical detection and they are either unfair, or not work-conserving. In this paper, the authors propose a class of work-conserving, collision-free, detection-free, and fair MAC protocols for opportunistic hyper-channels which are tailored hyper-channels for SMART.
