| Abstract(in English) | Network function virtualization (NFV) has begun to be introduced with the purpose of increasing the flexibility of providing network functions and reducing the cost of providing them. One of the problems to be solved in NFV is the problem of placing a virtual network function (VNF: Virtual Network Function).In this paper, focusing on a core-periphery structure as an approach to this problem, We evaluate the efficiency and stability when the extracted core function is placed. By the evaluations using service chain based on AS topology data and evaluations using generative model of service chain, about 24% service chain request can be processed when the core size is 128 (Functions). We also found that the efficiency and stability of the core increases as the request rate for VNF is less diverse. |
