Abstract: Virtualization is the base for a diversified next-generation network architecture design. Much work has been done on virtualization infrastructure, but it is still unclear how to easily instantiate a network slice that meets a high-level description of network functionality. Our work addresses this problem that occurs at the interface between network service providers and virtualized infrastructure providers. The proposed Service-based Network Virtualization System (SNVS), which is based on our previously developed network service architecture, provides a comprehensive and extensible interface to ease the development of new network services, protocols, and applications in virtualized networks.
