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
Copyright © NTT Communications Corporation. All rights reserved.
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.
