Abstract
Network virtualization is considered as an enabling technology to accomodate recently introduced new services such as cloud services and data center networks on top of the existing network environment. In this paper, an efficient virtual network mapping method is proposed which takes account of the location and resource requirements of virtual nodes and the bandwidth requirements of virtual links. The proposed method sets bandwidth as the priority metric for network mapping, and searches for a set of substrate nodes and paths that houses the virtual nodes and virtual links. Through the simulation experiments, it is verified that the proposed method provides better cost to revenue ratio and fast experiment time without degrading success rate of virtual network mapping.
