Multi-layer Challenge
Broadband Users Data Center
Layers of complexity• More rack space• More power• More cooling• Thousands of fibers• Personnel per layer• Maintenance fees
IP/MPLS

DWDM
fibers
OTNTransport Convergence• Reduces Space• Lowers Power/Cooling• Reduces fiber count• Lowers personnel costs• Increases Reliability
But Multi-layer Challenge Remains• IP/MPLS over Transport• No coordination across
layers• Slow manual operations• More failure points

Evolution Towards Intelligent Transport
Packet-Optical Transport(P-OTN)
Expensive Network Intelligence
Increase Scale, Reduce TCO
IP/MPLS Routers
ConvergenceMulti-layer Switching
OTN, WDM, ROADM, MPLS
ScalabilitySuper-channel Transmission
Coherent, Ready for 1TbE
AutomationOpen Software Control
Programmability, Resiliency
Intelligent Transport Networking
Intelligent transport networking simplifies total network & enables cost efficiency at Cloud scale.

Bandwidth growth & costs not aligned
• Organic cost reductions alone insufficient for minimizing cost/bit
Network layers operating in isolation, not cooperation
More cross-layer intelligence needed for optimizing traffic
Inter-layer/inter-domain control plane lacking
Why SDN for Multi-Layer Networking?Simplifying Provisioning, Enabling Optimization

Intelligent Transport drives new approach to scaling core• Service-ready capacity, BW delivery @ Internet speed
• Converged Digital (packet, OTN) and ROADM operations
Multi-Layer SDN has significant benefits• Streamline multi-layer, multi-domain operation
• Rapid application development through standard APIs
• New dynamic “on-demand” services (eg, NaaS, BoD)
• Global view creates opportunity for total network optimization
Carriers seeking evolutionary, open approach• Leverage key existing robust WAN control plane functions
• Open SDN control layer, flexible integration options
