光突发交换(OBS)是实现下一代光互联网中的一种极具前景的方案。该文提出了一种基于闽值的OBS网络数据信道调度算法,对于长度大于阈值的光突发数据包采用LAUC算法进行调度,对于长度小于阈值的光突发数据包采用LAUC-VF算法进行调度。仿真结果表明,该算法在调度时间方面与已有的LAUC算法很接近:而在光突发数据包丢失率性能方面要优于LAUC-VF算法。
Optical Burst Switching (OBS) is a promising paradigm for the next-generation Internet. In this paper, a threshold-based data channel scheduling algorithm is proposed, which uses LAUC to schedule long burst and uses LAUC-VF to schedule short burst. Simulation results show that the scheduling time of the proposed algorithm is close to LAUC, and the performance of data burst loss probability is better than LAUC-VF.
