A study of requirement definition in user-oriented virtual network architecture

Recent years have brought progress in flexible construction of network services through an open-flow or software-defined network (SDN). These existing methods, however, require equipment for exclusive use. This paper proposes a user-oriented virtual network service architecture that easily enables new network service construction from the user viewpoint. Concretely, a commercial server is installed on the user side, and an architecture for implementing new network services upon user demand only through software is proposed.
