OTN/ASON波长冲突解决算法研究

摘要

This paper briefly analyzed the causation of the wavelength conflict and the quasi-wavelength conflict in OTN / ASON meshwork,and gived a GMPLS-based RWA algorithm to solve the wavelength conflict in OTN / ASON meshwork,and described the basic models and principles of the algorithm.By data analysing,it is proved that the algorithm can effectively increase the utilization of the wavelengthes,and the wavelength-increment increased with the increasing of the size of the meshwork and the number of link connection section.%简要分析了OTN/ASON中产生波长冲突和准波长冲突的原因,初步给出了一种基于GMPLS协议解决OTN/ASON波长冲突的RWA算法,并对该算法的基本模型和原理进行了阐述.通过数据分析,证明该算法可以有效增加波长利用率,其波长增量随着网络规模和链路连接段的增加而增加.
