  1. The Open Networking Foundation: • OpenFlow & SDN from lab to market • IEEE ComSoc SV chapter • July 11, 2012 • Dan Pitt, Executive Director • Dan.Pitt@OpenNetworking.org

  2. Points to cover • Origins • The Basics • Why we exist • Ambition, scope • How we operate • What we’re doing

  3. Origins • Programmatic control of Enterprise networks • Global policy, directly enforced • Global vantage point • OpenFlow Ethane Martin Casado • NSF/GENI • OpenFlow/SDN on 10 campuses • Research demonstrations • Now on 100+ campuses • US, Europe, Asia Research Community: How to deploy new ideas? • Data Center Networks • WANs • Enterprise and WiFi • Vendors & startups emerging Industry Trend: Networks being built this way

  4. Why we exist • Users • Solving problems of scale, flexibility, east-west traffic (data centers) • Solving problems of cost, service introduction (service providers) • Solving problems of applications, administration, security (enterprises) • Networking • Catching up to computing (distributed systems, virtualization) • Becoming part of the computing infrastructure • Standards • User-led • Faster 4

  5. Domain problems • Carriers • End-customer monthly bill: unchanged • Global IP traffic: up 40-50% per year • CAPEX, OPEX need: down 40-50% per Gb/s per year • CAPEX, OPEX reality: down 10-20% per year • Service-creation velocity • Data-center operators • East-west traffic, already have global view • Unbelievable scale • Enterprises • Everything else is virtualized • Need flexibility to match IT to business needs 5

Program Feature Packet Forwarding Packet Forwarding Packet Forwarding Packet Forwarding Packet Forwarding Flow Table “If header = x, send to port 4” “If header =y, overwrite header with z, send to ports 5,6” “If header = ?, send to me” Separation of control, forwarding planes 10

  11. ONF basics • ONF • is a foundation for the advancement of SDN (including standardization) • is not a simple SDO • Vision • Make Software-Defined Networking the new norm for networks • Mission • Foster a vibrant market for SDN products, services, applications, users • Goals • Create the most relevant standards in record time to support a switching ecosystem based on the OpenFlow protocol • Accelerate understanding of how to realize the abstractions above OpenFlow

  12.

  13. ONF legal • A non-profit industry consortium 501(c)(6) • Incorporated 2010, Launched March 22, 2011 • Funded by member dues • Open to any org. that pays annual dues, agrees to bylaws, IPR policy • IPR policy • RAND-Z: royalty-free use of protocol, OpenFlow trademark, logo • Automatic cross-licensing of all related IP to all other members • No licensing charges to members • No protection for non-members • ONF itself: no IP • Open interfaces, not open source or reference implementations (yet)

  14. ONF principles • Operation • Fast, lean, efficient • Absent politics AMAP • A startup ourselves, iterating with customers, agile, learning • Standards creation • Driven by users and user needs • Developed by those close to implementation/deployment • Standardize as little as necessary • Vendor differentiation without lockin, market fragmentation • More and more like a software community • No names on drafts • Relevant, implementable now; protocol-agnostic eventually • Rapid real-world experience

  15. Technical Advisory Group Board of Directors Chairs Council of Chairs Executive Director Council of Chairs . . . Technical Working Group Market Education Activities Technical Working Group Regional Activities ONF governance • Board of Directors • Users, not vendors • Executive Director (employee) • Reports to the Board; vendor neutral • Technical Advisory Group • Advises Board on fundamental technical issues • Working Groups • Chartered by the Board • Chaired by Board appointee

  16. 7 Board companies, 65 others • Urs Hölzle (Sr. VP, Engineering, Google), chairman • Najam Ahmad (Director, Network Engineering, Facebook) • Adam Bechtel (VP, Infrastructure Group, Yahoo) • Stuart Elby (VP, Network Architecture, Verizon) • Axel Clauberg (VP, IP & Optical, Deutsche Telekom) • Yukio Ito (Sr. VP, Services & Infrastructure, NTT Communications • Clyde Rodriguez (GM, Windows Azure Networking, Microsoft) • Nick McKeown (Professor, EE and CS, Stanford) • Scott Shenker (Professor, EECS, UC Berkeley and ICSI) • NoviFlow • Oracle • Orange/France Telecom • Pica8 • Plexxi Inc. • Radware • Riverbed Technology • Samsung • SK Telecom • Spirent • Telecom Italia • Tencent • Texas Instruments • Vello Systems • VMware • ZTE • Ixia • Juniper Networks • Korea Telecom • LineRate Systems • LSI • Luxoft • Marvell • Mellanox • Metaswitch Networks • Midokura • NCL Comms K.K. • NEC • Netgear • Netronome • Nicira Networks • Nokia Siemens Netw. • ETRI • Extreme Networks • EZchip • F5 Networks • Freescale Semi • Fujitsu • Gigamon • Goldman Sachs • Hitachi • HP • Huawei • IBM • Infinera • Infoblox • Intel • IP Infusion • A10 Networks • ADVA Optical • Alcatel-Lucent • Aricent • Argela/Turk Telekom • Big Switch Networks • Broadcom • Brocade • Ciena • Cisco • Citrix • Colt • CompTIA • Cyan Optics • Dell/Force10 • Elbrys • Ericsson 16

  17. OpenFlow standards • Evolution path: • OF 1.0 (03/2010): Most widely used version, MAC, IPv4, single table (from Stanford) • OF 1.1 (02/2011): MPLS tags/tunnels, multiple tables, counters (from Stanford) • OF 1.2 (12/2011): IPv6, extensible expression • OF-Config 1.0 (01/2012): Basic configuration: queues, ports, controller assign • OF 1.3.0 (04/2012): Tunnels, meters, PBB support, more IPv6 • OF-Config 1.1 (04/2012): Topology discovery, error handling • OF-Test 1.0 (2H2012): Interoperability & conformance test processes, suites, labs • Goals: • Widespread adoption, experimentation w/OF 1.3.x • Accommodate current merchant silicon • Move beyond limitations of current merchant silicon 17

  18. Technical activities • Chartered Working Groups • Extensibility (chair: Jean Tourrilhes, HP): OpenFlow protocol • Config-mgmt (chair: Deepak Bansal, Microsoft): basic switch configuration • Testing-interop (chair: Michael Haugh, Ixia): conformance, interop., benchmarking • Hybrid (chair: Jan Medved, Cisco): mixed OpenFlow/legacy switches & networks • Discussion Groups • OpenFlow-Future: forwarding-plane models • NorthboundAPI: how the network relates to the applications • NewTransport: OpenFlow for optical, circuits, wireless • Market Education (chair: Isabelle Guis, Big Switch): marketing, customer value 18

  19. Conclusions • ONF now the home of OpenFlow • Take OpenFlow 1.1 to commercial strength – Job One • Family of standards: foundation, building blocks, choices • Protocols; configuration and management; compliance and interoperability • Development, deployment, experience, feedback • SDN beyond OpenFlow • SDN abstractions, object models, interactions • Ecosystem for new features, new players, new business models • Technical standards + market education • Market pull to drive the ecosystem
