Threshold-Based Data Channel Scheduling Algorithm for Optical Burst Switching Networks

  • 摘要: 光突發(fā)交換(OBS)是實(shí)現(xiàn)下一代光互聯(lián)網(wǎng)中的一種極具前景的方案。該文提出了一種基于閾值的OBS網(wǎng)絡(luò)數(shù)據(jù)信道調(diào)度算法，對于長度大于閾值的光突發(fā)數(shù)據(jù)包采用LAUC算法進(jìn)行調(diào)度，對于長度小于閾值的光突發(fā)數(shù)據(jù)包采用LAUC-VF算法進(jìn)行調(diào)度。仿真結(jié)果表明，該算法在調(diào)度時(shí)間方面與已有的LAUC算法很接近；而在光突發(fā)數(shù)據(jù)包丟失率性能方面要優(yōu)于LAUC-VF算法。
    Abstract: 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.
