| Abstract(in English) | In this paper，we propose a placement of multiple virtual service resources for a tree-topology virtual network．In the proposed method，the tree-topology is divided into two topologies based on the amount of traffic that passes each node．Then，a virtual service resource is placed at a node in each divided topology，and hence two virtual service resources are placed in the tree-topology virtual network．When this process is performed at $n$ times，$2^n$ virtual service resources can also be placed．By using this method，the total amount of traffic in the virtual network is reduced and the quality of services are maintained．We evaluate the performance of this method with simulation，and numerical examples show that the total amount oftraffic in the virtual network is reduced and a large number of virtual networks can be constructed over a physical network． |
