The PRAGMA Experimental Network Testbed (PRAGMA-ENT) is an international Software-Defined Networking (SDN)/OpenFlow testbed for use by PRAGMA researchers and collaborators. The goal of PRAGMA-ENT is to enable researchers to freely access network resources to develop, experiment with, and evaluate new ideas without concerns of interfering with a production network. The network programmability brought by SDN technology allow us to create a suitable research environment for each collaborative research. For this purpose, the participating researchers mutually agree to contribute and share a reasonable and minimal set of computing and network resources to build the testbed, and establish high-speed network connections between the organizations with national research and education network (NREN). This will expose SDN to the broader PRAGMA community and facilitate the long-tail of eScience by creating new collaborations and infrastructure among institutes in the Pacific Rim area.
In the CENTRA project, we would like to solicit more research experiments on the SDN testbed from the researchers who have research ideas needed to be evaluated on widely distributed environments. We would like to also extend this international infrastructure to broader communities and institutions through CENTRA.
