Hot Topics in SDN Panel Discussion
Why do transport networks need SDN?What are the challenges of making transport SDN work in the real world?How are we (industry, ONF, OIF) addressing these challenges?How to get started and get involved with transport SDNWrap-up and Q&A
Agenda
Carrier SDN Transformation
→ Proprietary, vendor-specific silos→ Complex to operate, integrate
across vendors/technologies
→ Centralized, vendor-agnostic control and service orchestration
→ Virtualization of physical network resources→ Open, programmable carrier networks

Wireless Transport WorkPOC Madrid October 2015• Supported by • Telefonica• 5 largest microwave
vendors (90% of the market)• Based on ONOS controller
with basic microwave port extensions • Presenting two SDN apps:• Capacity driven air
interface• Flow based shaping• Whitepaper available at ONF

SDN Framework for Transport Multi-Domain IntegrationTransport SDN framework for carrier networks• Can be realized over
diverse carrier networks• Highly flexible - multiple
technology layers, multiple domains, greenfield and brownfield
Need standards on application layer interface to control layer (NBI)• Programmability of
Transport SDN across controller and NE vendors
API Divergence ProblemAbsent Standards • Potential API
divergence• Vendor-specific• Controller-specific• Technology-specific• Language-specific• SDO-specific
• Need commonality• Common core model• Common minimal
subset• Plus extensions

Carrier view: what is needed to make SDN more widely deployable in the
service provider network
Vishnu ShuklaVerizon
Why Does Transport Need SDN?•Optical and transport networks continue to be difficult and expensive to manage, with many manual processes and very long provisioning times
•SDN and virtualization have the promise of simplifying optical transport network control, adding management flexibility, and allowing the rapid development of new service offerings by enabling programmatic control of optical transport networks and equipment
•Can also reduce the cost of optical switches by moving control and management planes from embedded processors to general-purpose COTS hardware and virtualized software
•Utilize centralized network-wide management and control to drive efficiency and speed

Potential Benefits of Transport SDNSDN Benefit Transport Network ImpactNetwork Utilization • Application-aware optimization of resources
• Multilayer optimization across packet and circuit
Improved Service Development/Deployment
• Greater separation of service development/deployment and network element embedded software
• Virtualization of network resourcesSimplified/Streamlined Operations • Streamline and integrate operations across
different domains• Circumvent or remove restrictions of legacy
operations systemsMonetization of Resources • Improved charging for network resource
usage and class of service
