8. Persistent Problems: Making Internet Infrastructure Worse “… in the thirty-odd years since its invention, new uses and abuses, …, are pushing the Internet into realms that its original design neither anticipated nor easily accommodates.” “Freezing forevermore the current architecture would be bad enough, but in fact the situation is deteriorating.” Overcoming Barriers to Disruptive Innovation in Networking, NSF Workshop Report, 05.

9. BIG CHANGES REPRESENT BIG OPPORTUNITIES

10. Big Changes Represent Big Opportunities Opportunities for • Research groups to shape future Internet • Startups to create new product categories • Incumbents to get into new markets and grow • Newcomers to leapfrog Not the time to sit on the sidelines

15. Barriers • Big-brother portals will own our data • We will be locked-in to applications • Wireless capacity will stay closed • Network will stay ossified Today Vision • Problem with the network. • 3G: Cellular networks a IP • IP: Bad for mobility, security, management • Need a network that continually evolves • When they’ve got our data, they’ve got us! • Surrounded by capacity we can’t use • Inefficient: Costs more, poorer quality • We need an alternative • Big-brother portals luring us to their repository • We have to provide an alternative • Healthcare, Financial: May never take off Where we will go otherwise

18. Mobile Network Infrastructure Today • Many cellular networks visible (5-7 common), many wifi networks visible (10-15 common). • But not practically available to me – closed infrastructures. • Seamless mobility impossible • Why can’t I use of all the infrastructure around me? WiFi cellular

19. Network Substrate Goals • Access to all infrastructure • Continued connectivity and seamless mobility as I move • Maximize user choice • Radio • Handoff • Allow innovation • Handoff mechanisms • AAA, billing, …

20. OpenFlow Switch specification OpenFlow Basics Net Services PC OpenFlow Switch OpenFlow Protocol API SSL Controller Secure Channel sw • Add/delete flow entries • Encapsulated packets • Controller discovery Flow Table hw

21. Example Network Services • Static “VLANs” • New routing protocol: unicast, multicast, multipath, … • Network access control • Home network manager • Mobility manager • Energy manager • Packet processor (in controller) • IPvX • Network measurement and visualization These & other services => a very different net substrate

24. OpenFlow and Mobility • Lots of interesting questions • Management of flows • Control of switches • Access control of users and devices • Tracking user location and motion • Lots of radio networks:WiFi, WiMax, LTE, … • Dumb access points • User choice

25. Deployment on Stanford campus • 100 of WiFi APs in 4 buildings & outdoor locations • A few Mobile WiMAX femto-cellbase stations • Deployed in this autumn • All are OpenFlow enabled & connected by OpenFlow switches • Plan to have a project class in this autumn/winter quarter WiFi AP (two radios/box) We are ready for innovation in our network! Mobile WiMAX AP

26. Broader Impact: OpenFlow Network Substrate • Eight switch vendors enabling this capability • Cisco, HP, NEC, Juniper, and others • We are starting to demonstrate the key capabilities • ACM SIGCOMM08 • GENI Engineering Conference • Supercomputing… • We are deploying • on our campus: two buildings at Stanford (HP/Cisco) • on other campuses in US and Japan – with NSF support • in national nets: US (Internet2, NLR), Japan (JGN2plus), Europe, … And enable researchers and network operators to innovate on topHope OpenFlow takes off -- on a path of no return
