SDN Control of Packet-Optical Networks
Goal
Multi-layer SDN control with ONOS for programmability and optimization across packet
and optical networks for a more efficient WAN.

Each network does its planning independently
resulting in overprovisioning and significant inefficiencies.

Provisioning of Optical networks is static and
lacks agility ( bandwidth on demand is slow)

Usage & States
ONOS provides:
•  NB Intent Framework for provisioning across
packet and optical
•  PCE for multi-layer optimal path selection
•  Network graph abstraction with both layers
•  Packet and optical Data model
•  Topology discovery of packet and optical
•  Pluggable SB for adaptors
•  Failure detection and rerouting
•  Visibility (GUI) and statistics
