Class differentiation isatremendous issue as adopted toresolve thecontention areexploring thetime aconsequence ofdiverse applications andthedrastically domainbyimplementing optical buffering. growoftraffic demands. Thus,thispaperinvestigates Consequently, this paper expedites wavelength dimension, this radical evolution withintensive explanation inorder instead ofemploying conventional optical buffering and todefine a suitable paradigm forclass differentiation deflection routing that havebeenstudied previously (4). This provisioning. Italsoinvestigates thepossibility ofhavingapproach eliminates theneedofoptical buffering atinput and classified packetpriorities for resolving packetoutput switch bydisplacing withtunable optical wavelength contention. Thispaperproposes a preemptive hybridconverter (TOWC). Moreover, class differentiation isan scheduling schemeforoptical packet switch.
