Abstract Optical Burst Switching (OBS) is a promising solution for realizing IP/DWDM. In this paper, two new data channel scheduling algorithms in OBS networks, Minimum Wavelength Conversion Times (MWCT) algorithm and Service Differentiation (SD) algorithm, are proposed. Computer simulation has demonstrated that MWCT algorithm leads to much fewer wavelength conversion times and the SD algorithm can provide better transmission reliability in OBS networks for high priority data comparing with the existing FF and LAUC algorithms.
