摘      要：Network functions virtualization(NFV) increases network flexibility and scalability by virtualizing network functions running on the general servers and opens the network innovations by outsourcing VNF instances in 5G ***,it leads to the incompatibility issue among different VNF instances,which makes operators difficult to determine which VNF instances to select for Service Function Chains(SFCs).In this paper,we divide VNF instances with high compatibility into clusters used for combining VNF instances in 5G ***,we define compatibility among different VNF ***,aiming to maximize compatibility of each cluster,we propose a novel hypergraph clustering model that divides the VNF instances into multiple ***,the hypergraph clustering model is transformed to an evolutionary ***,the cluster establishing is transformed to the game equilibrium ***,we propose a discrete time high order replicator dynamic algorithm to find the game ***,the simulation results show that the proposed approach can improve the quality of SFCs.
