  1. GENI and Software Defined Networking/OpenFlow for Universities: Motivation, Strategy, and Uses Jim Bottum Vice Provost and CIO Kuang-Ching “KC” Wang Holcombe Department of Electrical & Computer Engineering Bottum, Wang Clemson University July 12 2012 1

  2. Outline • GENI and OpenFlow/SDN: What are they? • Why bring OpenFlow/SDN to campus? • For research and education • For IT operation • OpenFlow at Clemson • OpenFlow deployment • Academic and IT use cases Bottum, Wang Clemson University July 12 2012 2

  3. “A university is an institution of higher education and research” Wikipedia “Cyberinfrastructure is the primary backbone that ties together innovation in research, instruction, and service to elevate Clemson to the Top 20”Doris HelmsProvost Cyberinfrastructure (CI) as University Backbone:Connecting People, Connecting Technologies Bottum, Wang Clemson University July 12 2012 6

  4. Research Areas Leveraging GENI/OpenFlow To Date • CIO office facilitated creation of cross-department faculty groups in different areas to explore CI use • Health care, GIS, transportation, energy, bioscience, arts & humanities, parks & recreation, architecture. • 10+ faculty working on funded research using GENI • Wired/wireless networking, network security, P2P computing, reconfigurable computing, cloud computing, automotive & transportation, smart energy grid • IT + faculty + student team on applied IT research • Undergraduate creative inquiry teams • Campus internship program + 4-year IT curriculum • Porting OpenFlow for IT service, e.g., security data analysis network, datacenter data transfer, identity management Bottum, Wang Clemson University July 12 2012 9

  5. Why University Needs More than Fast Networks • Increasing education service complexity • Complex education software (e.g., Blackboard) • Distributed, remote education • Increasing research demand of IT resources • With the same or less budget • CI needs across disciplines • Demand for cost effective IT infrastructure • Increasing production service liability • In a harsh world • Campus safety and disaster preparedness • Critical applications (internal/external enterprise services) • Security exploits Bottum, Wang Clemson University July 12 2012 8

  6. … And THE CLOUD is coming! [Cloud Computing implies that networks are dynamic things that automatically take you to where your data may be] [your network engineers are hiding under their desks] Bottum, Wang Clemson University July 12 2012 12

  7. External Drivers • Internet2 Innovation Platform • Condo of condos • SC Cloud • Dell CoE • HPC in cloud • Social Media Listening Center • CU-ICAR automotive research testbed • E-Health • Medicaid service delivery Bottum, Wang Clemson University July 12 2012 13

  8. Wide area network service distributed campuses, partner institutes Data center hosting services disaster recovery preparedness Unified campus network monitoring/management infrastructure Cyberinfrastructure across disciplines University has Increasing IT Services Needing More Sustainable/Reliable Process Bottum, Wang Clemson University July 12 2012 10

  9. The control plane is configurable, but not arbitrarily changeable Each device has its own isolated control plane Configuring Network and Compute Hosts Needs Intensive Labor and Experience There are at least two problems with that… [Networks never evolve…] […they just get more complex.] Bottum, Wang Clemson University July 12 2012 11

  10. What is a nightmare to a network engineer… OpenFlow/SDN on Campus: Naïve? Brilliant? Well, it’s not quite that simple. But, consider this… SDN lets you leverage this and creates real engagement between IT and Academics! Bottum, Wang Clemson University July 12 2012 14

  11. IP is the narrow waist • Protocols used today are • Very complex! • Not taught in classes! • Research challenge? No idea! • Complex to configure! Link/Physical: Numerous Network: IP Applications: Numerous Transports: TCP/UDP/RTP + others • OK, GENI will change this. • But how, and where to start? • Why OpenFlow/SDN is the start? Protocol Stack View Internet Today is Problematic for R&E, Operation Sensor/actuator Networks Wireless Access Networks Vehicle Networks Core: Ethernet, IP, MPLS, TE, BGP, OSPF Servers (Data Centers) Enterprise Networks Bottum, Wang Clemson University July 12 2012 15

  12. SDN/OpenFlow Controllers First, Identify the Key Strengths of OpenFlow/SDN Servers (Data Centers) • Software Defined Networking (SDN) • OpenFlow as one first commercial SDN solution • Network controlled by software controllers – automated operation • Centralized network view – simplified validation and management • Virtualized infrastructure – seamless, secured/isolated sharing Enterprise Networks Internet Sensor/actuator Networks Wireless Access Networks Mobile Networks Bottum, Wang Clemson University July 12 2012 16

  13. Trials Application Commercialization SDN/OpenFlow From Birth to Maturity Creation Bottum, Wang Clemson University July 12 2012 17

  14. OpenFlow Controllers Campus OpenFlow Deployment Strategy Servers (Data Centers) • Be cautious • There’s a learning curve • You’ll feel worried for a while • You will need help Enterprise Networks Internet Sensor/actuator Networks Wireless Access Networks Vehicle Networks • Be positive • It’s our mission • We can do this • We can take risks • We never run out of brains Bottum, Wang Clemson University July 12 2012 18

  15. SDN Deployment at Clemson – Our Strategy • Make it useful • “Discover “ potential users • Build a community • Do it incrementally • Implement real use cases • Collaborate with vendors • Make it sustainable • IT-academic collaborative operation • Innovative funding model Bottum, Wang Clemson University July 12 2012 19
