Software Defined Networking (SDN) is driving transformations in Research and Education (R&E) networks, enabling innovations in network research, enhancing network performance, and providing security through a policy-driven network management framework. The Holland Computing Center (HCC) at the University of Nebraska-Lincoln (UNL) supports scientists studying large datasets, and has identified a need for flexibility in network management and security, particularly with respect to identifying data flows. This problem is addressed through the deployment of a production SDN with a focus on integrating network resource management for large-scale GridFTP data transfers. We will discuss SNAG (SDN-managed Network Architecture for GridFTP transfers), an architecture that enables the SDN-based network management of GridFTP file transfers for large-scale science datasets. SNAG proposes a novel architecture that combines application- and network-layer coordination with SDN-enabled network management to manage, monitor and account for network resources used by GridFTP transfers. We will also discuss ScienceSDS, a novel software defined security framework for securely monitoring large-scale science datasets over a software defined networking and network functions virtualization (SDN/NFV) infrastructure. Finally, we will discuss other recent and ongoing projects in the areas of Optical networks, Internet of Things and Future Internet.
