Today, we are going to talk to you about…
We , as NTT Communications, have deployed SDN technologies into our production services. In earlier phase, we have deployed SDN into inside DCs and have provided cloud services using SDN. In the next step, we have expanded SDN region to WAN and LAN of enterprise customers.
I’m really honor to be here to show you joint project of Transport SDN or Packet Optical technology development

Most of our enterprise customers want to use multi cloud environments, including AWS, Azure, GCP, and so on, from Application-centric points of view. So, seamless connections among these environments will be real useful for our customers.
We think that our enterprise customers also want to use muli-network environments including from highspeed virtually dedicated networks , VPN, MPLS, or besteffort/ low-price networks. These demands are also from Applicaton-centric points of view. They want to use networks with best fit with applications’ requirements.
There are two activities to tackle them. For overlay perspective, .. We have just launched new overlay or SD-WAN service named “….”

Our transport network environments can be explained by three features:
Distributed network functions deployments: Intelligent network nodes that handle multilayer conversion and Ether OAM have been distributed all over the world.
Hardware-based aggregation: Each nodes has various hardware-based network functions.

8. Ref) CORD Evaluation at Okinawa Open Laboratory
Purpose
Evaluate CORD from the perspective of production network deployment
Action Plan
Step 1: Build and evaluate Trellis
Step 2: Construct VNF Platform with E-CORD
Step 3: Field trial at Okinawa
Step 4: Install CORD into production network
Now we built Trellis environment and started testing several items for Trellis.
Details will be presented in E-CORD Track on Thursday:
“Service Provider Experiences with E-CORD: NTT Communications & OOL” November 9 3:00pm– 3:30pm
Finally, I will summarize our presentation.
As mentioned in the part 1, NTT Communications are developing Transport-SDN technology for long and we’ve already deployed the Transport-SDN system to our commercial product. Now, we are challenging to adopt the disaggregated transport network devices and open source SDN controller, ONOS.
Meanwhile, in collaboration with many service providers including NTT Communications, ON.Lab has successfully shown the PoC of ONOS-based open and disaggregated optical transport networks. Now, ON.Lab is leading to develop ONOS controller for disaggregated transport networks with its open source community toward commercial quality.
Based on the PoC result in ON.Lab, NTT Communications has started the lab trial and field trial of disaggregated transport networks since last year. Through the trials, we will continue to evaluate and feedback the controller’s requirements to the ONOS community for the further development of ONOS. And also we will continue the field trial and confirm the stability and operations of open and disaggregated transport networks.
