Performance analysis of optical burst switched node with deflection routing

Abstract

As the optical network evolves from static long haul connection provider to an adaptive and "smart" backbone solution, optical burst switching (OBS) becomes an attractive scheme for its flexibility and efficiency. However, how to reduce data loss is a crucial issue in such an asynchronous and one-way reservation system. In this paper, we study one contention resolution strategy in OBS networks: deflection routing. We extend an existing work to provide approximate and accurate models for the data loss analysis of single OBS node with and without wavelength conversion capability. The accuracy of our models is evaluated by simulation results.
