OpenFlow Switch Donation Enables Research and Education
Source: RENCI News
CHAPEL HILL - With funds from the GENI Project Office (GPO) distributed through Stanford University, RENCI and its Triangle area university partners recently received five OpenFlow-enabled network switches valued at $3,000 per unit.
The donation is meant to help campuses create or expand their OpenFlow networks for both research and production uses.
The switches will be deployed on campuses and in the Points of Presence of RENCI’s Breakable Experimental Network (BEN), a regional optical network test bed used for experiments with disruptive networking technologies.
The OpenFlow switches will be connected to BEN and will enable new cutting-edge networking research and educational opportunities at UNC-Chapel Hill, NC State University and Duke University. They will be installed over the next few weeks at the BEN PoPs at RENCI and UNC Chapel Hill and in laboratories and facilities of the computer science departments at Duke, UNC Chapel Hill and NC State.
OpenFlow is an open standard developed at Stanford that allows researchers to run network experiments on campus networks. It is added as a feature to some commercial Ethernet switches and makes it possible to separate the switch’s packet forwarding, or data, path from its high-level routing decisions, or the control path. The separation of paths lets researchers easily deploy innovative routing and switching protocols in networks and is especially useful on networks that run virtual machines, need high security or involve research on next-generation Internet protocols.
“OpenFlow is a great addition to the research network infrastructure on our campuses,” said Ilia Baldine, RENCI’s director of networking research. “Having OpenFlow on BEN is especially important because BEN is our test bed for the National Science Foundation GENI Initiative. It gives us more flexibility with experiments involving network and compute and storage infrastructure that can support a cloud computing Infrastructure as a Service (IaaS) paradigm.”
GENI, the NSF-funded Global Environment for Network Innovation, includes several multi-campus networking research teams who are prototyping and designing this global experimental facility. RENCI’s GENI research is a partnership with Duke University researchers to deploy the Open Resource Control Architecture (ORCA), a software framework developed by Duke computer scientist Jeff Chase, on BEN. The BEN GENI “island” is a part of the expanding GENI test bed infrastructure.
In addition to enhancing research using BEN, OpenFlow technology also will support experiments and educational programs in the three universities’ computer science programs.
- At UNC-Chapel Hill, the OpenFlow-enabled switch in the computer science department’s networking laboratory will give students hands-on experience implementing and evaluating OpenFlow technology and will present a new focus for research projects.
- At NC State, the switch will connect a general-purpose test bed used by computer science students for research and class projects, giving students the chance to study OpenFlow as a platform used in network programming.
- At Duke, OpenFlow will be integrated into coursework on distributed systems, operating systems and data-intensive systems.

Editor's Note: Dr. Rudra Dutta, associate professor of computer science at NC State said, “OpenFlow is a combined virtualizing and flow-routing network system. The beauty of OpenFlow is that it neatly separates the intelligence or “smarts” of strategies of packet routing (what paths to follow, how to treat different packets in different ways) over a network from the drudgework of actually forwarding the packets. It can be a great teaching tool because it allows students to imagine complex new routing or traffic engineering strategies of their own, then perform simple programming to realize them on OpenFlow, and then have an industrial strength switch to actually follow their strategy. Having actual OpenFlow equipment will enable us to continue to expand educational activities.”
