Analysis of effect of different factors on burst dropping probability in optical burst switching network

Abstract

With an explosive growth of the Internet, optical network seems to be the candidate solution for future high-speed backbone networks. Optical burst switching (OBS) has been proposed as promising switching technology for the next generation wavelength division multiplexing (WDM) based network. The main issue in OBS based network is to reduce burst dropping probability. We classify different factors that affect burst dropping probability based on the schemes in which they are used. Schemes are like scheduling algorithm, burst assembly and burst reservation and factors are void filling and non-void filling scheduling algorithm, burst size, burst assembly schemes, offset time and different classes of traffic. This paper studies an impact of all above mention factors on to burst dropping probability with the help of extensive simulation on NS2. Simulation results shows that, different parameter must be properly used in the network. © 2010 Springer-Verlag Berlin Heidelberg.
