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

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

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

Why University Needs More than Fast Networks
Bottum, Wang Clemson University
8
• 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

[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]

Configuring Network and Compute Hosts Needs Intensive Labor and Experience
Bottum, Wang Clemson University

There are at least two problems with that…
The control plane is configurable, but not arbitrarily changeable Each device has its own isolated
control plane
[Networks never evolve…] […they just get more complex.]

OpenFlow/SDN on Campus: Naïve? Brilliant?
Bottum, Wang Clemson University

Well, it’s not quite that simple. But, consider this…
What is a nightmare to a network engineer…
SDN lets you leverage this and creates real engagement between IT and Academics!

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

First, Identify the Key Strengths of OpenFlow/SDN
• 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

– Be positive
• It’s our mission• We can do this
– We can take risks– We never run out of brains

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

• From reactive to proactive networking– Mobile IP: Distributed, reactive (long latency), requires compatible
agents everywhere, provider-dictated– OpenFlow: Centralized, proactive, solutions for diverse network
scenarios, opportunities for both provider and client customization
