Motivations for SDON

SDON: Software-Defined Optical Networking

• Growing demand for data center/cloud interconnection.

• Need to dynamically setup high-volume pipe via multiple

core/metro/access optical networks for data centers

OpenFlow-based OPS/OCS unified

control plane

• OpenFlow Agent (OFA) is introduced to control OPS/OCS equipment.

• The OFA virtualizes the resources of the OPS/OCS nodes for the

controller, and translates OpenFlow protocol into commands that can

be understood by the equipment.

• End-to-end path provisioning in OPS/OCS network using the

OpenFlow-based network controller.

SDN/MPLS 2014

Optical Packet & Circuit Integrated Network for Metro Network

• User view: A “high-speed, inexpensive” service and “low delay, low data-loss” service on a single optical network

• Network provider view: Large switch capacity (>100Gbps Optical Packet), energy saving, and flexible & efficient resource use under a simple control

• Switching tables for OPS and optical paths for OCS can be set up via OpenFlow Controller
