A virtual network approach to network resources management

grantor: University of TorontoIn this thesis, we discuss the virtual network concepts and introduce a management architecture for the control of virtual networks. The management architecture is intended to provide a programmable networking environment, where multiple virtual networks can be generated out of a single physical network to be utilized for various management purposes. We first define a virtual network and related concepts in a generic manner; discuss how physical network resources can be allocated to virtual networks; and present how an hierarchy of virtual networks can be created. We then introduce the virtual network resources management architecture. The management architecture is designed modularly to be scalable over geographical and administrative boundaries. Lastly, we present a dynamic binding technique that allows customization of network control and management functions, and a real-time bandwidth management technique that enables network-level multiplexing.M.A.Sc
