Dynamic Routing of Reliability-Differentiated Connections in Optical Burst Switched Networks

Optical Burst Switching (OBS) is one of the most promising next-generation all-optical data transport paradigms. As networks become increasingly distributed and autonomic, Optical Burst Switching becomes the right choice for the next generation optical Internet. In this paper, the authors propose a mechanism for Dynamic Routing of Reliability-Differentiated Connections (DRRDC) in Optical Burst Switched networks. The proposed mechanism consists of two subschemes namely Adaptive Routing, a loss minimization mechanism that selects the least congested route for burst scheduling and Adaptive Burst Cloning, a technique for providing loss recovery in an OBS network.
