The document summarizes an agenda for a session reviewing progress towards wide-scale adoption of SDN in transport networks. It will include a presentation on a global transport SDN prototype demo by OIF, a discussion of the OIF's SDN framework and APIs by Ciena, and a presentation on virtual transport network services by Verizon. The session aims to identify technical and business challenges preventing broader SDN adoption and provide components of a toolkit to help clear the path towards widespread deployment of SDN in transport networks.

2. Abstract
Recent proof-of-concept, prototype technology demonstrations and
field trials have shown progress in the evolution to commercial SDN
deployment. Service providers, network element providers and
software vendors are collaborating in standards bodies, industry fora
and laboratories to identify and address technical and business
challenges standing in the way of broader market adoption.
In this session, OIF panelists will review findings from its Global
Transport SDN Prototype Demo and outline components of a tool kit
aimed at clearing a path to wide-scale transport SDN deployment.

5. About the OIF
The Optical Internetworking Forum:
• Represents an end-to-end ecosystem
membership base…
• Focused on multi-layer and multi-
domain transport interoperability…
• Optimized for IA development and
interop testing…
• Fills gaps, removes obstacles…
• Accelerates market adoption and
ROI for new technologies…
• Improves network efficiency, lowers
Opex/Capex for network operators…
• Unlike any other forum or SDO www.oiforum.com

6. Why Does Transport Need SDN?
• Optical and transport networks continue to be difficult and expensive to
manage
• Many manual processes
• Very long provisioning times
• SDN and virtualization have the promise of:
• Simplifying optical transport network control
• Adding management flexibility
• Allowing the rapid development of new service offerings by enabling
programmable control of optical transport networks
• To improve optical networking operations cost and ROI by:
• Automating services provisioning and deployment
• Improving network resource utilization

7. Goal: Seamless Interworking
• Efficient, Agile Multi-layer, Multi-vendor, Multi-domain Carrier

8. Challenges
• Operational simplicity
• On-board new clients rapidly
• Differentiated service delivery
• Automate resource allocation on the fly
• Scalability
• Support X transactions per hour
• Security
• Service isolation and authentication per client
• Continuous Availability
• Disaster avoidance / recovery
• Current transport business model

11. Carrier Requirements on
Transport Networks in SDN Architectures
• Based on contributions of major
carriers worldwide
• Comprises requirements on
Transport SDN
• Orchestrator (transport network
relevant part)
• Control and management
planes
• Data plane
• Being used as guidance within
OIF but also communicated to
other SDO’s and forums

12. General Requirements
• Requirements are not aimed at a particular set of protocols,
HW and SW implementations
• Packet & circuit switching
• Centralized & distributed control instances
• Allow multiple protocols
• Modular SW and HW (COTS)
• Decoupling of network layers
• Guarantee interoperability among different vendor
implementations, carrier network domains, data center
functions, …
• Well defined interfaces for an increased level of interoperability
