Ryu SDN framework-open-source SDN platform software

Abstract

We introduce Ryu SDN Framework, an open source software (OSS) system developed by NTT, and describe our efforts toward promoting its wider adoption. Ryu SDN Framework is a platform that provides tools and libraries for easy use of SDN (software-defined networking). We have taken advantage of the strengths of OSS in developing Ryu, which conforms to the most recent industry-driven OpenFlow specifications. Ryu is used by a variety of experts including SDN application developers, network device developers, and network service maintainers.
