An OBS Network Design Method based on Iterative Local Minimization of Average Blocking Probability

Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose a Routing and Wavelength Assignment (RWA) algorithm, in Optical Burst Switching networks with centralized control. The algorithm tries to minimize expected total blocking time. The expected total blocking time is higher order polynomial of route/wavelength assignment variables, thus it is hard to find global minimizer. We show that the minimization on each variable is to find the minimum value among given weights assigned for pairs of routes and wavelengths. Based on this observation, the proposed algorithm iteratively minimize the expected total blocking time to find locally optimum solution.
