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

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

3 Networks being built this way
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

6 Vertically integrated
Remember mainframes? App Specialized Applications Linux Mac OS Windows (OS) or Open Interface Specialized Operating System Specialized Hardware Microprocessor Open Interface The mainframe industry in the 1980s was vertical and closed: it consisted of specialized hardware, operating system and applications --- all from the same company. A revolution happened when open interfaces started to appear. The industry became horizontal. Innovation exploded. Vertically integrated Closed, proprietary Slow innovation Small industry Horizontal Open interfaces Rapid innovation Huge industry

7 That’s what today’s routers are
Routing, management, mobility management, access control, VPNs, … Million of lines of source code Feature Feature 6,000 RFCs OS Custom Hardware Billions of gates Bloated Power Hungry Vertically integrated, complex, closed, proprietary Networking industry with “mainframe” mindset

8 Vertically integrated
What SDN really is App Specialized Features Control Plane or Open Interface Specialized Control Plane Merchant Switching Chips Open Interface Specialized Hardware Vertically integrated Closed, proprietary Slow innovation Horizontal Open interfaces Rapid innovation

9 Network OS The transition Feature OS 9 Custom Hardware Custom Hardware

10 Feature Ctl. Program Network OS
Separation of control, forwarding planes 3. Consistent, well-defined global view Feature Ctl. Program 2. At least one Network OS probably many Open- and closed-source Network OS 1. Open interface to 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” Packet Forwarding Packet Forwarding Packet Forwarding Packet Forwarding Packet Forwarding 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 Slicing Layer: FlowVisor

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
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 Council of Chairs Executive Director Board of Directors Technical Advisory Group . . . Technical Working Group Market Education Activities Regional Chairs Council of Chairs

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) ETRI Extreme Networks EZchip F5 Networks Freescale Semi Fujitsu Gigamon Goldman Sachs Hitachi HP Huawei IBM Infinera Infoblox Intel IP Infusion Ixia Juniper Networks Korea Telecom LineRate Systems LSI Luxoft Marvell Mellanox Metaswitch Networks Midokura NCL Comms K.K.

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 (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
