Network virtualization has received attention as a way to allow for sharing of physical network resources. Sharing resources involves mapping of virtual nodes and links onto physical nodes and links respectively, and thereafter managing the allocated resources to ensure efficient resource utilization. In this paper, the authors apply artificial neural networks for a dynamic, decentralized and autonomous allocation of physical network resources to the virtual networks. The objective is to achieve better efficiency in the utilization of substrate network resources while ensuring that the quality of service requirements of the virtual networks is not violated.
