For the network function virtualization (NFV) environment, the existing virtual network feature (VNF) placement algorithm is difficult to optimize network energy consumption and network delay. This paper constructs an NFV. The network energy consumption and processing delay cost model. The energy consumption in this model includes server energy consumption and link energy consumption. The delay includes processing delay and link transmission delay in the network. Based on this model, this paper proposes an optimization algorithm combining simplex method and genetic algorithm. The simulation results show that compared with the random mapping algorithm, the algorithm designed in this paper can optimize the network energy consumption while ensuring the quality of service.
