SUMMARY:INDIS Keynote: The Relevance of Software Defined Exchange Points i
 n the Path of Scientific Workflows
DESCRIPTION:Workshop\n\nINDIS Keynote: The Relevance of Software Defined E
 xchange Points in the Path of Scientific Workflows\n\nIbarra\n\nInternatio
 nal research network connections are increasing, providing new paths for s
 cientific workflows to move data and work across continents:  In the north
  Atlantic between North America and Europe, the Advanced North Atlantic (A
 NA) collaboration operates 740G of distributed bandwidth capacity; between
  the U.S. and South America, the AmLight Express and Protect (AmLight-ExP)
  project added three 200G optical waves between Florida and Brazil, for a 
 total capacity of 630Gbps; the AmLight-SACS project will be activating a 1
 00G optical wave between Brazil and Angola, establishing a new south Atlan
 tic route between the Americas, Africa and Europe; and Bella, a project le
 d by RedCLARA and GEANT, will provide new high-capacity network paths betw
 een South America and Europe. While this phenomenon provides the opportuni
 ty for network operators to add resiliency to the global R&E fabric, it al
 so adds complexity to network management and traffic engineering. \nSoftwa
 re Defined Exchange points (SDX) provide enhanced capabilities to simplify
  flow-management and enable new network services.  Unlike traditional exch
 ange points, an SDX controller has global visibility of the network topolo
 gy, making it possible to maintain related states for the full path of a f
 low.  This presentation will describe what an SDX is and why SDXs are rele
 vant to scientific workflows in the global R&E network fabric. The Atlanti
 cWave-SDX project and its SDX controller will be presented as a novel dist
 ributed programmable controller along with use cases for two science drive
 rs.  Results from extensive experiments in a testbed will be presented tha
 t demonstrate the AtlanticWave-SDX controller’s high performance in terms 
 of scalability, response time, and resource utilization, which are extreme
 ly important to support advanced scientific applications. Finally, future 
 work will be described to clarify where SDXs can have an impact on the glo
 bal R&E network fabric.\n\nTag: Workshop Reg Pass, Big Data, Data Analytic
