OFC 2019 Session: The goal of SDN is to enable flexible, automated and programmable networks that reduce Opex and accelerate service delivery. Realizing open, interoperable multi-vendor optical networking is one key to achieving this goal. A panel of industry experts will discuss the drivers, needs, and challenges in the evolution to widescale adoption of open, interoperable optical networks: - Definition and specific requirements - Risks, trade-offs and benefits - Disaggregation, open line systems, and APIs - Use cases, interop testing, trials and deployment scenarios - Implementation agreements, interoperability demonstrations and certification testing Moderator: Dave Brown, Director of Communications, OIF, Product Marketing Senior Manager, Optical Networking, Nokia, USA Speakers Victor Ló​pez , Technology Expert at Systems and Network Global Direction, Telefónica gCTIO, Spain Lyndon Ong, Market Awareness & Education Committee Co-chair - Networking, OIF and Ciena, USA Jonathan Sadler, Network Interoperability Working Group Chair OIF and Infinera, USA

Interoperability Testing
- Validate specs
- Real world use cases
- User lab testing
- Determine gaps
- Publish findings
Spec/IA Development
- Identify needs, gaps,
issues
- SDO liaisons and
partnerships
- Refine and evolve Ias
Certification
- Determine needs
- Establish process,
specs, use cases
- Promote, execute
- Establish as RFx
table stakes
Develop standard transport SDN interfaces

6. The OIF and Transport SDN
 Goal: accelerate commercial deployment by defining, testing and
assuring interoperability of key network functions and interfaces
 Work to date:
 Use cases and reference architecture
 Carrier requirements and framework
 2014 interop demo – partnered with ONF, tested pre-standard ONF OpenFlow extensions
and APIs, led to ONF T-API specs
 2016 interop demo - validated specs in multi-layer, multi-domain environments in carrier
labs, led to T-API 2.0
 2018 T-API 2.0 interop demo
• Next:
• Integrated Packet Optical SDN Requirements project
• T-API certification
