Group Scheduling for MultiChannel in OBS Networks

Abstract

Group scheduling is a scheduling operation of optical burst switching networks in which the burst header packetsarriving in each timeslot will schedule their following bursts simultaneously. There have been many proposals for groupscheduling (such as OBS-GS, MWIS-OS and LGS), but they consider mainly to schedule the arriving bursts which have thesame wavelength on an output data channel. Another suggestion is GreedyOPT which considers the group scheduling formultichannel with the support of full wavelength converters, but it is not optimal. This article proposes another approachof group scheduling which is more optimal and has a linear complexity.
