                     Roadmap to a Networkless World
                 draft-liu-nmrg-networkless-roadmap-01

Abstract

   This document aims to illustrate possible approaches to make network
   management and operations more autonomic in several aspects.  The
   ultimate goal is that the network could run all by itself, so that
   users and administrators may feel that there is no network to take
   care of at all (a.k.a.  "Networkless").  The approaches are described
   in a form of different levels (inspired by the Self-Driven Car
   levels).  The higher the level is, the more autonomic management
   capabilities the network would have.

   Although some specific technologies are categorized into different
   levels, it is not the document's intent to rank them; rather, this
   document is more about discussing the possible next stage and the
   ultimate vision.  Hopefully, this document could collect people's
   consensus in the industry and provide guidance for future technology
   developments.

1.  Introduction

   As the network is evolving rapidly, the system is becoming more and
   more complex; thus managing a network is more and more challenging.
   It has been a common feeling in the industry that the operational
   expense of running networks is becoming a vital pain point.  To
   address the management complexity challenges, there are new
   technologies emerging.  For example, Autonomic Networking [RFC7575],
   which is under standardization in IETF Anima working group [Anima],
