A scheduling algorithm minimizing voids generated by arriving bursts in optical burst switched WDM network

摘要

In this paper, we propose a scheduling algorithm minimizing voids generated by arriving bursts in optical burst switched WDM network. In the proposed scheduling algorithm, when the burst which has arrived at optical core router a certain time can be transmitted in some data channels by using the unused data channel capacity(Void), our proposed scheduling algorithm selects the data channel in which a void newly being generated after the burst transmission becomes minimum. We compare the performance of our proposed scheduling algorithm with that of the conventional one with respect to burst loss ratio by computer simulations. As a result, we show that our proposed scheduling algorithm can improve the burst loss ratio compared to a conventional one.
