RENCI, Duke to Build Experimental Networking Infrastructure PDF Print E-mail

Monday, 12 December 2011 14:18
RENCI at the University of North Carolina, Chapel Hill and Duke University in partnership with IBM will lead a new project to build a nationwide test bed for networking and networked cloud computing.
The project is part of NSF’s Global Environment for Network Innovation (GENI) initiative, which enables researchers to explore networks of the future.
The National Science Foundation (NSF) awarded just over $2 million to the three-year ExoGENI project, led by Ilia Baldine, director of RENCI’s networking research group and Jeff Chase, a Duke University computer science professor.
The project will deploy and operate 13 ExoGENI sites at research universities and labs across the U.S.  The project will use software based on the Open Resource Control Architecture (ORCA) to control the networked cloud infrastructure. The project team developed the ORCA platform in earlier NSF-funded research and extended it for use in the GENI initiative.

ORCA Team at SC11 PDF Print E-mail

At SC11 conference the RENCI/Duke ORCA team demonstrated the capabilities of the ORCA provisioning software to create slices of computational and network substrate spanning the entire country. The slices were used to compute molecular properties of candidate solar fuel catalyst materials for a related DOE-funded project. The computation involved a number of serial steps computed on dynamically provisioned cloud resources in NC, connected via BEN, to the DOE Hopper super computer, on which 3000 cores were used to complete the last step. Pegasus workflow management system orchestrated the computation steps within the slice. 

To create the slices ORCA concatenated dynamic circuits acquired from National Lambda Rail (via Sherpa), ESNet (via OSCARS) and BEN into a single Layer 2 high-bandwidth circuit. It also dynamically provisioned cloud resources at UNC, RENCI and Duke to enable the execution of the workflow.

CHAPEL HILL, February 18, 2011–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, North Carolina State University and Duke University. They will be installed over the next few weeks at the BEN PoPs at RENCI and UNC Chapeil Hill and in laboratories and facilities of the computer science departments at Duke, UNC Chapel Hill and NC State.
