Zusammenfassung
Optical network virtualization presents the necessary technologies to provide the specified set of network requirements, while providing the necessary isolation between network slices. In this chapter, technologies from both data and control plane perspectives are presented for virtual optical networks (). Firstly, the benefits provided by adopting software-defined networks () and network function virtualization () technologies are introduced. Secondly, the need for a network operating system is discussed, and a reference architecture for optical networks is presented. Thirdly, a methodology for describing virtual and physical network resources is provided. Fourthly, a review of different VON resource allocation algorithms is presented. Finally, an NFV architecture supporting VON is presented, among several use cases.
