Levels of Autonomous Network Technologies (draft-liu-nmrg-networkless-roadmap-00) Bing Liu, Brian Carpenter @NMRG, ietf 102, July 2018 1

Background • Network OPEX is always an important issue • New network automation technologies are emerging: – SDN for configuration/service delivery – New emerging Intent-driven/based Network – AI for autonomous control, diagnostic etc. • Maybe it’s useful to draw an road map of how relevant technologies could evolve to the ultimate goal (named as “Networkless” in this draft)? 2

Two Dimensions of the Levels • Final Effect in Operators’ Perspective – Self-Organization • Bottom line: various Plug-n-Play techniques (joining in the domain, get connect with NMS, build adjacencies/routes etc. ) – Self-Configuration • Bottom line: NMS/Controller automatically pushes configurations to devices – Self-Optimization • Bottom line: ECMP, TE etc. – Self-Diagnostic • Bottom line: – Self-Healing • Bottom line: VRRP, FRR etc. • Key capabilities of Network Systems – Network perception • Bottom line: various measurement, telemetry and network visualization techniques – Decision/Reasoning • Bottom line: protocol-based control loops, machine learning based self-decision – Operational interface • Bottom line: primitive device API for software control/management 4

Open Discussion • Is it valuable to do such a work? • The two dimensions are reasonable? • Any thing missing in the “Self-X” part; and also the “Key Capabilities” part? • Other specific comments 6

Next step • Feedback are highly needed – This work cannot be done by only few people – Reaching consensus of the industry in the goal • Might consider a more intuitive result for each level 7
