Recently, application services have become more and more diversified as new technology advances. The applications of Augmented Reality (AR) have received great attention from academics and operators. However, the complex computing required for AR applications has caused service operators to face the problems of poor user experience due to insufficient computing resources. Network function virtualization (NFV) enables operators to directly establish network functions on virtual machines and can flexibly adjust the number of each virtual network function (VNF) according to users' requirements. Thus, the system can reduce unnecessary waste of resources. In addition, we use multi-access edge computing (MEC) to provide computing resources. The edge server is close to users and reduces transmission cost of the system. This paper proposes an MEC-based VNF placement and scheduling scheme for AR applications. Considering the functional topology of AR applications, the compute-intensive application can provide good service quality for a large number of users within limited resources. The simulation shows that the proposed method can maintain good service quality as the number of user requests increases.
