The switch is widely compliant with OpenFlow 1.3 and features performance and functions suitable for both data centers and wide area networks.The corporation has also established the SDN Switches Test Center, which is leveraging the "Ryu SDN Framework" already released as OSS.Through these activities NTT aims to expand OSS-based SDN eco-systems with the participation of various companies, universities, and research organizations.

1. BackgroundIn recent years SDN (*1) and NFV(*2) have become particularly important in the drive to achieve adaptive and rapid network deployment and added functionality for network services. The focus of these technologies is on software-oriented rather than hardware-oriented network functions, especially dedicated LSIs. As SDN begins to be implemented into data centers, it is expected that its advantages will also be applied to wide   area networks(*3). Thus, wide functionality and high-performance forwarding are required for controllers and switches, both of them principal components of SDN.

In the field of SDN switches, NTT Network Innovation Laboratories are promoting R&D in the O3 Project(*4) as part of a "Research and Development of Network Virtualization Technology" program commissioned by the Ministry of Internal Affairs and Communications. A prototype SDN software switch "Lagopus" that enabled 10 Gbps forwarding was successfully developed in December 2013. Demonstrations and presentations of Lagopus have been warmly applauded by network experts and given them high expectations for its future.

In the area of SDN controllers, NTT Software Innovation Center released the "Ryu SDN Framework" as OSS in 2012. The framework has since been modified to extend its functionality with the participation of various companies, universities, and research organizations. Specifically, the Ryu SDN Framework can handle not only OpenFlow(*5), one of the leading  specifications for SDN development, but also a wide variety of protocols needed for coordination with existing network nodes. In consequence it was   unhesitatingly selected by Broadcom Corporation, a firm which is developing OpenFlow enabled LSIs, OpenStack Project(*6) engaged in cloud platform construction and other activities.
