English abstract:
In optical burst-switched (OBS) networks, packets are aggregated into a burst that is sent an offset time after the control data. The amount of processing overhead is reduced in the packet. The process of aggregating high and low-priority traffic into a single burst is known as composite burst assembly. High-priority packets are placed at the head of the burst and low-priority packets at the tail of the burst. In order to resolve contention, a void-filling-based scheduler drops low-priority packets from the tail of a burst. In this paper, we propose that high-priority packets should be placed in the middle of a burst and low-priority packets at the head and tail ends of a burst. That allows dropping of low-priority packets from the head and the tail of a burst when it contends with two other bursts where the head of the burst contends with one burst and the tail contends with another. The simulation results show that high-priority traffic faces reduced blocking at the cost of increased blocking of low-priority traffic. Also, the effect of varying the proportion of high-priority packets in the middle of the burst has been studied.
