Staged Approach

• Define OpenFlow feature
• Add OpenFlow to commercial switches and APs
• Deploy at Stanford
• Integrate with GENI Clearing House
• Deploy on many college campus networks
• We all create lots of open-source software so
  researchers can build on each others work
• (Were part-way into Stage 2)

Many Open Questions!

• Scalability of a controller
• Load-balancing over redundant controllers
• Federation, hierarchy and aggregation
• Protecting the controller against DDOS
• Our goal is to enable the research community to
  explore all these questions
