Abstract (in Japanese) (See Japanese page) 
(in English) With the assumption that the Service-over-core network will be used as the framework of the communication network, we have reported how to set and/or release virtual networks, provided to support services, over the carrier's core network, and information about how to define VPN tunnels for building virtual network. We divide the many services into resource service groups, RG-k where k=1,2,-, which share the same communication resource, and separate multiple wavelengths into wavelength groups inside the optical circuit network, wave-Gk where k=1,2,-. IP packets sent by a service that belongs to group RG-k should be transferred by the wavelength assigned to group wave-Gk. The concept of resource groups avoids the overlap of resources among services, such as telephony and services running on the Internet, whose communication quality needs are quite different. We have described the information needed and the procedures used to build virtual networks for multiple communication services. Each communication service can use core network functions, provided by core network, to set and release VPN tunnels, a virtual network element for the service, and modify the structure of its virtual network, by adding and/or releasing VPN tunnels to / from the network.
