Classical approaches to quality-of-service (QoS) provisioningin IP networks are difficult to apply in all-opticalnetworks. This is mainly because there is no optical counterpartto the store-and-forward model that mandates theuse of buffers for queuing packets during contention forbandwidth in electronic packet switches. Since plain IP assumesa best effort service model, there is a need to devisemechanisms for QoS provisioning in IP over wavelength-division-multiplexing, or IP-over-WDM, networks. In thispaper we propose a new scheme, called Preemptive PrioritizedJust Enough Time (PPJET), for QoS provisioningin buffer-less optical burst switching (OBS) networks. PP-JETprovides strict priority for high priority traffic by droppingreservations belonging to lower priority traffic using anew channel scheduling algorithm called Preemptive LatestAvailable Unused Channel with Void Filling (PLAUC-VF).Furthermore, we study the performance of PPJET throughsimulation experiments, and we show that PPJET outperformsPrioritized Just Enough Time (PJET) in terms ofdropping probability and end-to-end delay.
