The Way to Support Virtual Resource Mapping Within Dynamic Network Infrastructure

Network virtualization therefore refers to the integration of physical hardware and software network resources and network functionality into one software control entity - a virtual network. Virtual networks enable several different kinds of heterogenous Logical networks to share the same Physical network. The main work in incarnating virtualization is to provision the physical network resources to a given virtual network by mapping the virtual resources to the physical equipment dynamically in order to leverage the available equipments. Opinions derived from experimental as well as real life scenario reveal that mechanisms of virtualization will be the key enabler of end to end Quality of Service assurance in the network architecture. This paper considers how to arrange the virtual services approaching the task of virtual resource mapping in network environment, with possibility to focus on the network elements performing the network functions and interfacing with prospective networking solutions.
