摘要/Abstract

摘要：

分析了动态业务条件下，带可调谐波长变换器的多粒度光交叉连接节点结构特点，并提出一种适用于多粒度光交换网络的动态路由和波长分配算法——波长变换最长波带匹配（WC -LBM）算法. 该算法在动态业务到达时充分利用已有的波带和波长资源，通过使用已有波带、新建波带、新建波长以及使用可调谐波长变换器等不同的优先顺序实现连接的建立. 利用NSFNET网络拓扑对上述算法进行了仿真实验，并与传统的光交叉连接 (OXC) 节点和多粒度光交叉连接 (MGOXC)节点构成的光网络的业务阻塞性能进行了比较，结果表明，具有可调谐波长变换器的MGOXC组成的网络阻塞性能优于已有的网络.

关键词: 多粒度光交换, 可调谐波长变换器, 动态路由和波长分配

Abstract:

The characteristics of the multigranularity optical cross connect (MG-OXC) node with the tunable wavelength converters is analyzed. A new dynamic routing and wavelength assignment algorithm which is applied in multi-granularity optical switching network is also proposed. The performance of the MG OXC with tunable optical converters, compared with traditional OXC and MG-OXC, is evaluated with help of numerical calculations under NSFNET topology. The results show that the performance of the network with MG-OXC with tunable wavelength converters is superior to that of the network composed with only traditional OXC and MG-OXC.

Key words: multi-granularity optical switching, tunable wavelength converter, dynamic routing and wavelength assignment
