Abstract (in Japanese) (See Japanese page) 
(in English) We take note, from the viewpoint of the enterprise user, of IP core networks, overlay networks and communication services, with regard to cloud computing systems. The current approach to building overlay networks, overlay node (ON) and routing node (RN) inside common network are connected directly, has problems in terms of reliability and security. An improved architecture, the “Service-over-core network” as network framework, is described. Each service is built by connecting its access networks and service management sites, which may include similar servers, to end nodes placed at the periphery of the core network. No network virtualization technique for making multiple services install onto common network seems necessary. We think that the faults of dependable overlay network, in terms of business use and security, can be overcome by modifying its basic structure into the service-over-core network.
