Limited Delay Preemption Based Priority in Differentiated Optical Burst Switching Networks with Small Buffers ()
ABSTRACT
The composite scheme based on preemption and small
buffers is an efficient method for contention resolution. To support services differentiation,
it is the first time that the analytical model of delay preemption based
priority is built. Further, in order to guarantee the low-loss requirement for
high priority bursts, an improved scheme is proposed and investigated by
limiting the buffered right of low priority bursts within the specific traffic
states. The simulation results show that, without the deterioration of blocking
performance, there is more than 40% reduction on burst loss being achieved
under the conditionρ=1.0 for high priority bursts.
