作者的研究解决了一些基本的设计原则，一类新的城域网（MAN）的基础上，目前的光波技术，光交换波分复用（WDM）网络。WDM网络的一个独特功能是能够在给定的物理拓扑上创建许多不同的虚拟拓扑。作者描述了与光交换WDM网络设计有关的问题，研究了规则虚拓扑嵌入规则和不规则物理拓扑的问题，列出了嵌入规则虚拓扑的一些特性，并提供了一种计算虚拓扑嵌入所需最大波长数的方法。<<ETX>>
The authors' research addresses some of the underlying design principles for a new class of metropolitan area networks (MANs) based on current lightwave technology, optically switched wavelength-division multiplexed (WDM) networks. A unique feature of WDM networks is their ability to create many different virtual topologies on top of the given physical topology. The authors describe problems associated with the design of optically switched WDM networks, study the embedding of regular virtual topologies into regular and irregular physical topologies, tabulate some characteristics of embedded regular virtual topologies and provide a procedure for computing the maximum number of wavelengths required for virtual topology embeddings.<<ETX>>
