Fault detection method based on the minimum-length probe cycle cover algorithm in optical burst switching network

An economical minimum-length probe cycle cover algorithm is proposed in terms of costly sing-hop test module in meshed OBS networks, which uses the minimum-length probe cycle to find cycle cover for meshed OBS networks. Then each cycle is assigned a probe module, and a fault detection mechanism based on probe cycle cover is formed. At the same time, the generated alarm matrix is optimized, realizing the complete fault localization. The simulation and statistic results show that in this fault detection mechanism comparing minimum-length probe cycle cover algorithm to the existing algorithms, it has the least amount of network resources (measured by the number of cycles, cycle length, etc.) and higher fault localization degree.
