Abstract(in English) In recent years, network virtualization technology has attracted attention to operate plural network services on a substrate network. In order to design plural virtual networks (VNs) on a substrate network, Virtual Network Embedding (VNE) problem has been studied for effective resource allocation.The VNE problem can be solved by using a mixed integer linear programming problem (MILP). However, the MILP problem for a large-scale network cannot be calculated due to the huge amount of variables used in the computation.Therefore, conventional researches have been proposed heuristic algorithms for improving the calculation time. However, this method has problems that calculation accuracy is deteriorated and the VN rejection ratio increases.In order to cope with this problem, we have proposed the MCG method. The MCG method selects the number of candidates from the substrate nodes for mapping a virtual node and we showed the availability of the proposed method.In this paper, we evaluate the blocking probability in the case of increasing the required load by increasing the number of VN requests, and we analyze details of the cause of blocking.
