Gearing Up for Transport SDN Deployment
Light Reading Big Telecom Event 2015Chicago, IL USA
June 10
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 fora and laboratories to identify and address technical and business challenges standing in the way of even early market adoption.
In this session, OIF panelists will review 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

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

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

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
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
