Abstract
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.
