1 SDN Standardization in ONF: ONF Structure, OpenFlow Spec & ONFs SDN Architecture Fabian Schneider (NEC Laboratories Europe), Vice-chair Architecture WG, ONF ITU Workshop on Software Defined Networking (SDN) Standardization Landscape (Geneva, Switzerland, 4 June 2013) Geneva, Switzerland, 4 June 2013

2 2 ONF: What and Why ONF owns OpenFlow spec standardization Mission: Dedicated to the promotion and adoption of SDN for the benefit of users ONFs view on SDN: Physical separation of forwarding and control Simplification of networking devices ONF is not only yet another SDO Too many SDOs are vendor-driven Disruptive tech wont evolve from legacy SDO Being an SDO is not enough to achieve mission Geneva, Switzerland, 4 June 2013

3 OpenFlow approach in a Nutshell The OpenFlow protocol provides a standardized protocol to separate control/ management plane from data plane Rules (Match/Action tuples) Support for quick & dynamic network configuration OF 1.0 – OF 1.3.2, OF-Config Network Apps Network Apps Custom Control Plane Custom Silicon Apps Control Plane Data Plane Data Plane Geneva, Switzerland, 4 June 2013

4 4 OpenFlow protocols & SDN SDN is much more than just OpenFlow protocols Whole eco-system: SDN Apps Network OS Network Elements Interfaces in between Control Plane Data Plane Applications API Network Operating System API Switch/Network Element API SDN Geneva, Switzerland, 4 June 2013

5 ONF OVERVIEW Self-perception, Governance, Structure, Membership 5 Geneva, Switzerland, 4 June 2013

6 ONFs self-perception Promote SDN as a whole – its commercialization – for users Standardize what needs to be standardized by a committee Believe in OpenFlow protocols as the Southbound API standard Advocate of experimentation, coding, open-source 6 Geneva, Switzerland, 4 June 2013

7 7 ONF Governance Board of Directors: Users, not vendors Executive Director (employee) Reports to Board; vendor-neutral TAG: ONFs CTO function Working Groups Chartered by Board Chaired by Board appointee CoC coordinates between different WGs Geneva, Switzerland, 4 June 2013

8 Current ONF Structure & WGs 8 Optical Transport Testing & Interop Council of Chairs (CoC) Technical Advisory Group (TAG) Board of Directors Executive Director (Dan Pitt) Arch & Frame- work Config & Manage- ment Exten- sibility Fwding Abstrac- tions Market Edu- cation Migration Geneva, Switzerland, 4 June 2013

9 ONF member statistics OpenFlow industry acceptance 22 users 70+ products, 30M+ ports Incumbent support for OpenFlow spec Board: 8 companies & 2 Professors 96 Members operators, service providers, vendors, chip makers; both incumbent & startups 9 Geneva, Switzerland, 4 June 2013

10 ONF ACTIVITIES Current work items, Peak into Architecture 10 Geneva, Switzerland, 4 June 2013

11 11 Current Activity Build out the OpenFlow substrate Optical, Wireless/Mobile, Security, OAM Plug-fests and Conformance testing Develop ONFs SDN Architecture Support services above OpenFlow protocol Northbound interface study Hooks for NFV How to migrate from legacy networks Foster Chipset/HW Ecosystem Geneva, Switzerland, 4 June 2013

12 Peak into ONFs SDN Architecture 12 Geneva, Switzerland, 4 June 2013

13 Three Critical Properties of ONFs SDN Architecture Apps are network aware: SDN-enabled Apps Communicate their requirements/polices to the network Can monitor network state and adapt accordingly Logically centralized NW: SDN Network Controller Controller translates from app reqs to low-level rules Controller summarizes the network state for apps Well-understood driver-like model for devices: SDN Datapath Programmatic low-level control of all Fwding and config API for capabilities advertisement and publishing stats No resource contention with other entities Controller owns this device, subject to capabilities advertisement* 13 Geneva, Switzerland, 4 June 2013

14 ONF COLLABORATIONS & LIAISONS 14 Geneva, Switzerland, 4 June 2013

15 Strategic ONF Collaborations Geneva, Switzerland, 4 June

16 Established ONF Liaisons Geneva, Switzerland, 4 June

17 Conclusions and Recommendations SDN: the future of networking open, programmable, vendor-neutral, standards where it needs to be Industry: broad acceptance of OpenFlow and investment everywhere ONF: driving the global commercialization of open, standards-based SDN Try to avoid duplication of work across SDOs More Geneva, Switzerland, 4 June
