1. Gearing Up for Transport SDN Deployment
Light Reading Big Telecom Event 2015
Chicago, IL USA
June 10
2. 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.

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

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

Since 1998 OIF has brought together industry groups from the data and optical worlds
Mission: To foster the development and deployment of interoperable products and services for data switching and routing using optical networking technologies
Our 100+ member companies represent the entire industry ecosystem: Carriers and network users, Component and systems vendors,
Testing and software companies
Example IAs: CEI, 100G LH DWDM, UNI & NNI
Challenge: Allow network providers to manage the underlying technical complexity of their networks
Support vendor innovation while: Preserving interoperability, Maximizing performance, Minimizing costs
Removing roadblocks: Proprietary solutions, Lacking or lagging standards, Lack of opportunities for collaboration
OIF Removes those Roadblocks: Building industry consensus, Contributing to formal standard bodies, Accelerating progress through collaboration
The implementation focus of the OIF work is show in this graphic. The events on the top of the timeline show approvals of the UNI and E-NNI control plane implementation agreements. Below the timeline are shown multi-vendor and multi-carrier interoperability events to test evaluate and improve the different IAs. This demo is the 6th in a series that have expanded in scope every year. The demo model in use since 2004 is to distribute the equipment in carrier labs for a global demo, allowing carriers to get first-hand experience. An important outcome of the demos is a set of “lessons learned” which is used to improve the underlying specifications, not just of OIF but of other standards bodies as well.
