Current networks are designed for peak loads leading to low utilization of power resources.In order solve this problem, a heuristic energy-saving virtual network embedding algorithm based on the Katz centrality (Katz-VNE) is proposed.For solving an we introduce represent node influence.In minimize energy consumption substrate network, problem formulated as integer linear program, and Katz-VNE used problem.The tries embed nodes onto with high centrality, which effective, uses shortest paths offering best factor bandwidths avoid hot nodes.The simulation results demonstrate that long-term average reduced significantly, revenue/cost ratio, acceptance rate requests, hibernation well links improved significantly.
