摘　　要：结合国内外最新的研究动态,针对有限波长转换能力的光突发交换网中亟待解决的突发包资源竞争问题,探讨了各种传统的波长分配算法,并通过对其特点的分析和综合比较,提出了一种新的适合有限波长转换能力光突发交换网特点的动态波长分配算法,此算法可以实现更低的全网突发包阻塞率。By reference to the latest research developments at home and abroad, various conventional wavelength assignment algorithms are investigated in view of the burst resource contentions in Optical Burst Switching （OBS） networks with limited wavelength conversion capabilities. A novel dynamic wavelength assignment algorithm that suits this kind of networks is proposed on the basis of the analysis and comparisons of their characteristics. This algorithm promises still lower burst blocking rate in OBS networks.
