“…Multiple virtual networks are constructed by using the network virtualization technology on a substrate network with network resources such as memory, CPU, and bandwidth [8,9,10]. Virtual networks have already been used in several use cases [11,12], and it is expected that network virtualization technology can be utilized in more situations. As a system that utilizes the network virtualization, a system where a service provider constructs virtual networks over a substrate network and provides them with users has been utilized.…”

Multiple virtual networks are constructed by using network virtualization technology on a substrate network with network resources. By using virtual service resources, a particular service can be provided with users over each virtual network. Moreover, network virtualization for mobile users has been expected in the future network service. In mobile virtual networks, mobile user moves from a node to other nodes and connects to other access points frequently. Therefore, the traffic on each link and each node in the virtual network changes. Because the quality of the service depends on the amount of traffic on links and nodes, the quality of services changes according to the user's movement. This paper proposes replacement algorithm of virtual service resources with dynamic resource allocation based on traffic change for mobile applications in virtual networks. In our proposed method, the amount of resources for each node and that for each link are changed based on the traffic change. Moreover, the virtual service resource moves to the adjacent node from a node, and this replacement is repeated until the quality of service satisfies the requested quality. With our proposed method, it is expected that the quality of service can be maintained for mobile users even if the amount of traffic changes. We evaluate the performance of our proposed method with simulation. In numerical examples, it is shown that our proposed method is effective when a larger number users move and the amount of traffic changes.

With the network virtualization technology, multiple virtual networks can be constructed on a substrate network with a part of substrate network resources. By using virtual service resources, a particular service can be provided to users over each virtual network. The quality of the service is affected by the amount of traffic on each virtual network. Therefore, virtual service resources are expected to be replaced in the virtual network based on the traffic change and topology change. This paper proposes a replacement method of virtual service resources for a virtual network with tree structure. In our proposed method, when the amount of traffic changes on any virtual node or the network topology changes, virtual service resources are replaced based on the tree structure so that the amount of traffic in the virtual network can be reduced. Moreover, we extend our proposed method so as to replace 2 virtual service resources. We evaluate the performance of our proposed method with simulation. In numerical examples, it is shown that our proposed method can construct a larger number of virtual networks and maintain the quality of the service.Network virtualization technology has been utilized actively worldwide [1]- [3]. By using the network virtualization technology, virtual networks are constructed on a substrate network with network resources such as CPU, memory, and bandwidth [4]- [7]. Virtual networks have already been used in some use cases [8], [9]. In the substrate network, each virtual network can be constructed and utilized independently each other. Even in the 5th generation networks, virtual networks are also expected to be constructed and utilized with network slicing technology [10]. In order to construct virtual networks, some construction methods have been proposed for substrate networks [11].
