Start Wavelength Assignment Policy - A Wavelength Contention Resolution for Optical Burst Switching Networks

Abstract

Most studies of optical burst switching (OBS) networks are under a fundamental assumption that full wavelength conversion is available throughout the network. In practice, however, economic and technical considerations are likely to dictate a more limited and sparse deployment of wavelength converters in the optical network. Therefore, we present a new start wavelength assignment policy for the absence of (full) wavelength conversion capabilities in the OBS networks. The performance study indicates that, our new scheme is robust under wavelength continuity constraint as well as Poisson and self-similar traffic
