In order to improve the efficiency of university network management and reduce the operating costs,this paper proposes a general framework of university network based on network function virtualization to optimize the university network management.Firstly,combining the network function virtualization and cloud computing technology,the overall network architecture is designed to improve the reliability and elasticity of the network.Then,a mixed integer linear planning optimization model is established for cost minimization to minimize the total network cost by reasonable allocation of data center resources.Finally,the effectiveness of the proposed model is evaluated through experiment.The results show that the model can greatly reduce the cost of the university network.
