The Pacific Rim Application and Grid Middleware Assembly (PRAGMA) is an<br />
international community of researchers that actively collaborate to address<br />
problems and challenges of common interest in eScience. The PRAGMA Experimental<br />
Network Testbed (PRAGMA-ENT) was established with the goal of constructing an<br />
international software-defined network (SDN) testbed to offer the necessary<br />
networking support to the PRAGMA cyberinfrastructure. PRAGMA-ENT is isolated,<br />
and PRAGMA researchers have complete freedom to access network resources to<br />
develop, experiment, and evaluate new ideas without the concerns of interfering<br />
with production networks.<br />
In the first phase, PRAGMA-ENT focused on establishing an international L2<br />
backbone. With support from the Florida Lambda Rail (FLR), Internet2,<br />
PacificWave, JGN-X, and TWAREN, PRAGMA-ENT backbone connects Open\-Flow-enabled<br />
switches at University of Florida (UF), University of California San Diego<br />
(UCSD), Nara Institute of Science and Technology (NAIST, Japan), Osaka<br />
University (Japan), National Institute of Advanced Industrial Science and<br />
Technology (AIST, Japan), and National Center for High-Performance Computing<br />
(Taiwan).<br />
The second phase of PRAGMA-ENT consisted of evaluation of technologies for<br />
the control plane that enables multiple experiments (i.e., OpenFlow<br />
controllers) to co-exist. Preliminary experiments with FlowVisor revealed some<br />
limitations leading to the development of a new approach, called AutoVFlow.<br />
This paper will share our experience in the establishment of PRAGMA-ENT<br />
backbone (with international L2 links), its current status, and control plane<br />
plans. Discussion on preliminary application ideas, including optimization of<br />
routing control; multipath routing control; and remote visualization will also<br />
be discussed.
