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

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
