Abstract� Recent proof-of-concept and prototype technology demonstrations
have shown progress in the evolution to commercial SDN deployment. Service providers, network element providers and software vendors are collaborating in standards bodies, industry foraand laboratories to identify and address technical and business challenges standing in the way of even early market adoption.
� In this session, the OIF reviews findings from its Global Transport SDN Prototype Demo and outline steps aimed at clearing the roadblocks to wide-scale transport SDN deployment.

About the OIF The Optical Internetworking Forum:• Represents an end-to-end ecosystem
membership base…• Focused on multi-layer and multi-
domain transport interoperability…• Positioned at the industry
crossroads…• 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

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
4
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

OIF is providing guidance to accelerate deployment by Addressing some Challenges
Network Orchestration
Controller Hierarchy
Multi-domain Architecture
SDN Framework SDN APIsService Request
Path Computation
Topology
� Providing carriers with essential tools in the Transport SDN toolkit
• How to apply SDN to a carrier’s multi-domain, multi-layer transport network
• Transport SDN API specifications to allow deployment of SDN applications
• Prototyping and testing of real implementations for experience and interoperability
2014 Global Transport SDN DemonstrationAddressing the Challenge
Multi-Domain Carrier Transport SDN Framework
� Application Layer• Business apps• Network apps• Orchestration
� Isolated from Controller
• Accesses Control layer via NorthBound Interface such as REST/JSON

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
Moving Transport SDN ForwardOIF Activities
SDN Reference ArchitectureCarrier SDN RequirementsMeaningful demo and testing in carrier environment showing
• Status of technology• Interfaces and interoperability• Operation tools needed• Pertinent use cases
Framework for Transport SDN• Define framework• Identify open interfaces• SDN and ASON
• API implementation agreements• Joint work with ONF
• Virtual Transport Network Service definition
