Packet Transport

Optical (Electric)

Optical (Photonic)

Closed services & infrastructure layers

Infrastructure evolves to be Packet-Optical, more open

SDN = Open Forwarding, Control, and Programmability … initially for packet services & infrastructure

ONF Optical Transport Group Adding Optical to SDN

Multi-Layer SDN + Openness = More Intelligent, Agile, Efficient Networks

Integrating the SDN topology model, cost, and path computation leads to Multi-Layer SDN
