The Developing Applications with Networking Capabilities via End-to-End SDN (DANCES) project was a collaboration between The University of Tennessee’s National Institute for Computational Sciences (UT-NICS), Pittsburgh Supercomputing Center (PSC), Pennsylvania State University (Penn State), the National Center for Supercomputing Applications (NCSA), Texas Advanced Computing Center (TACC), Georgia Institute of Technology (Georgia Tech), the Extreme Science and Engineering Discovery Environment (XSEDE), and Internet2 to investigate and develop a capability to add network bandwidth scheduling capability via software-defined networking (SDN) programmability to selected cyberinfrastructure services and applications. DANCES, funded by the National Science Foundation’s Campus Cyberinfrastructure – Network Infrastructure and Engineering (CC-NIE) program award numbers 1341005, 1340953, and1340981, has investigated three vendor network devices in order to determine which implements the OpenFlow 1.3 standard with DANCES requirements of meters and per-port queueing in order to provide a network reservation and rate-limiting capability desired to implement the goals of DANCES. Of the devices tested the DANCES project determined that the Corsa DP6410 met the requirements of OpenFlow 1.3 especially the implementation of features of metering and per port queueing which allow complex quality of service configuration for network flows. After selection of the network device a test environment was setup between the University of Tennessee and PSC to simulate a supercomputer center compute and data transfer resource environment. This paper described the DANCES project, the DANCES OpenFlow 1.3 specification requirements, the determination and acquiring of a sufficient OpenFlow 1.3 network device, the provisioning of a test environment, the UT-NICS test plan and the exciting and successful results of the tests.
