NTT Communications’ Expectations for Disaggregated Transport Networks and ONOS

•  Expectation for disaggregated-transport NW •  Agility and CAPEX/OPEX reduction

•  Expectation for ONOS •  Community influence •  Cost reduction •  Programmability of northbound on top of ONOS

Transform our transport network operationwith disaggregated-transport NW and ONOS

Market

Carriers

ON.Lab

•  Initial appearance of disaggregated ROADM product

•  PoC of disaggregated ROADM •  Plan and start next development of

ONOS for disaggregated ROADM •  Providing requirements

•  Increase of disaggregated ROADM vendors

•  Appearance of disaggregated Packet-Transport products

•  ONOS Development •  Next PoC of Packet-Optical

use case •  Field trial (NTT Comm)

•  Step1 Q1 •  Step2 Q2-3 (if step1 successful) •  Step3 Q4 and beyond

(if step2 successful)

•  Commoditization •  Continuous ONOS development •  ONOS will be the de fact

controller for disaggregated transport NW

•  Continuous field trial •  Commercial service deployment

(to be decided according to both the technical evaluation through the field trial and business strategy)

Protection Modeling

Most of transport network have protection mechanism High-speed switching (< 50ms) Automatic protection switching initiated by devices Controller is informed after the fact ONOS Intent Framework will work with protection Pre-compute and configure alternate path Visibility into current working path

#ONOSProject

Layered Intent

18

Carrier’s transport network consists of multi-layer network Need to represent relationships across multiple layers’ intent Analyze impact across layers for monitoring and trouble shooting Utilize (third-party) multi-layer PCE apps
