SPRACE participation in Supercomputing Conference 2015


An international team of high energy physicists, computer scientists, and network engineers led by the California Institute of Technology (Caltech), São Paulo State University in Brazil (Unesp) and University of Michigan, together with teams from Florida International University, Vanderbilt University and support from vendors including Dell, Mangstor, Mellanox, QLogic, SGI and Spirent are working together to demonstrate large data flow transfers across a highly intelligent software-defined network (SDN). The demonstration is based on a 100G OpenFlow-based ring connecting 7 different booths on the Austin Conference Center: Caltech, Univ of Michigan, StarLight, Dell, Vanderbilt Univ, Stanford Univ and Echostreams. Several remote institutions will be connected to this ring by means of WAN connections, including a multi-10Gbps link to SPRACE installed at Unesp Center for Scientific Computing. Unesp resources comprise two high-end servers provided by Intel and a top-level 100Gbps switch provided by Dell. Some of the WAN connections are being built using Internet2's NSI (Network Services Interface) and then stitched using a custom SDN application. This helps in creating an intelligent design where large flows traverse across various paths based on either the shortest or fastest routes availability. The team led by Caltech and SPRACE has just released a first working library to control the SDN controller OpenDaylight (Lithium). The library is written in Python and is available at: https://pypi.python.org/pypi/python-odl/ .
