A fast fault detection and localization mechanism for meshed optical burst switching networks

In this paper, a new fast fault detection and localization mechanism based on network partition strategy is proposed for meshed Optical Burst Switching (OBS) networks based on monitoring-cycles (m-Cycle). The algorithm has been applied to four typical networks and compared to the other three algorithms in terms of the cost of monitors, fault localization degree and the average wavelength overhead and so on. The computation and statistic results show that the mechanism for the networks whose average node degree is above 3.0 has the features of the least amount of network resources, higher fault localization degree, etc.
