Transport SDN

Introduce SDN to transport network

STEP1: Constructing 100G-PTS (using MPLS-TP)

STEP2: Control multi layer/multi domain using SDN

Demo scenario

Scenario1: Virtual resource visualization

Scenario2: End-to-end path computation & provisioning

Scenario3: Global repair

Scenario4: Data for analytical use


Knowledge From the Trial

SDN agility Easy to treat virtual resource Importance of common modeling Absorption of a performance difference Practical use of API with high convenience Flexible arrangement of software Fusion to Big Data New Use Case

Applying SDN to the transport NW reduce OPEX in the long term and create new services.
