By combining software defined network (SDN) and network function virtualization (NFV), and applying them to the resource orchestration problem of service function chains (SFC) deployment, the three-tier architecture consisting of SDN controller, network function virtualization and physical underlying computing resource layer in the process of heterogeneous network resource mapping is considered. An optimization algorithm for active control resources based on SDN and NFV is proposed. First, the user's utility is modeled by the multi-standard aggregated multi-criteria utility algorithm, and the optimization goal is transformed into a user's utility maximum problem. Then, based on the algorithm's prediction of the future state and real-time monitoring of the network utilization, the controller makes decisions and issues control commands for the arriving SFC requests, which is then used to occupy the underlying resources held by the virtual network function. The simulation results show that compared with the static timing resource allocation algorithm, the proposed active control algorithm performs better in terms of resource utilization, acceptance rate, and user creation utility.
