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

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

3 Origins 1.Programmatic control of Enterprise networks 2.Global policy, directly enforced 3.Global vantage point 4.OpenFlow Ethane Martin Casado Research Community : How to deploy new ideas? 1.NSF/GENI 2.OpenFlow/SDN on 10 campuses 3.Research demonstrations 4.Now on 100+ campuses 5.US, Europe, Asia Industry Trend: Networks being built this way 1.Data Center Networks 2.WANs 3.Enterprise and WiFi 4.Vendors & startups emerging 3

4 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 5 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 Domain problems 5

6 Vertically integrated Closed, proprietary Slow innovation Small industry Specialized Operating System Specialized Operating System Specialized Hardware Specialized Hardware App Specialized Applications Specialized Applications Horizontal Open interfaces Rapid innovation Huge industry Microprocessor Open Interface Linux Mac OS Mac OS Windows (OS) Windows (OS) or Open Interface Remember mainframes? 6

7 Million of lines of source code 6,000 RFCs Billions of gates BloatedPower Hungry Vertically integrated, complex, closed, proprietary Networking industry with mainframe mindset Custom Hardware OS Routing, management, mobility management, access control, VPNs, … Featur e Thats what todays routers are 7

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

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

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

11 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 ONF basics ONF is a foundation for the advancement of SDN (including standardization) is not a simple SDO 11

13 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 ONF legal 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) 13

14 Operation Fast, lean, efficient Absent politics AMAP A startup ourselves, iterating with customers, agile, learning ONF principles 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 14

15 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 ONF governance Council of Chairs Executive Director Board of Directors Technical Advisory Group...

17 17 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 OpenFlow standards 17

18 18 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 Technical activities 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 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 Conclusions 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 19
