Abstract:In order to full realize the performance of multi-traffic contention in OBS network core node, this paper studied the multi-priority traffic contention resolution model in optical buffer equipped OBS core node, which based on the preemptive channel occupied scheme. Several results indicate that, the proposed model not only can support the quality of service of OBS network, but also can resolve two limitations in the previous works effectively. Parameters derived from the model can provide theoretical references to the testing construction of OBS network.
