2 Agenda What is NetroSphere concept which advocated by NTT Labs? NetroSphere architecture with NFV/SDN functions Benefit of NetroSphere - Drastic cost reduction Global efforts focused on promoting key technologies of NetroSphere Call for collaboration with us 2018 NTT corp. All Rights Reserved. 2

3 Initial expectations for Open Networking Programmability Open and fast innovation In the datacenters, we don t login to each of the virtual machines to configure them. Everything is automated. We want to do the same thing for the network. - Urs Hoelzle, Google (ONS 2012) If you want a new function, we have to convince the vendors to implement. Even if we were able to do it, we have to wait for a long time - Igor Gashinsky, Yahoo (ONS 2011) Commoditization High-end router x86 server Open SDN Interface General purpose switch 2018 NTT corp.

5 Announced by NTT in Feb Break up the functions into small modular components, and flexibly assemble those components at will.

6 Challenges for Carrier-grade NFV/SDN Replacing a Big Box to a Cluster of small modules provides significant benefits, but also gives you many challenges Controller Carrier-grade NFV Platform Major vendors monopoly over key technologies for carrier requirements -> Key to solve: Provide carrier-grade functions as a common platform that can be widely used Carrier-grade SDN architecture Use commodity switches for carrier WAN Achieve high scalability and reliability -> Key to solve: A new design of SDN architecture High end router Switch Cluster Orchestration of various components Skills to assemble numerous multi-vendor components -> Key to solve: Simple architecture and a smart orchestrator 2018 NTT corp.

7 Steps toward NetroSphere Conventional NFV/SDN NetroSphere Phase 1 All in one, Separated, Leverage vendor silo but still vendor silos open technologies (e.g. OSS) NetroSphere Phase 2 Modularization at sub-device level Service Processing Packet forwarding Service Processing Service Processing OSS Service Processing Dynamic Assembly Vendor A Packet forwarding NFV&SDN Vendor A Packet forwarding Vendor A Additional R&D Effort Vendor ABC to Z OSS Packet forwarding Vendor ABC to Z Future Evolution OSS OSS Software Storage NIC Resource Pool 2018 NTT corp.
