Abstract

   Network telemetry is the technology for gaining network insight and
   facilitating efficient and automated network management.  It engages
   various techniques for remote data collection, correlation, and
   consumption.  This document provides an architectural framework for
   network telemetry, motivated by the network operation challenges and
   requirements.  As evidenced by some key characteristics and industry
   practices, network telemetry covers technologies and protocols beyond
   the conventional network Operations, Administration, and Management
   (OAM).  It promises better flexibility, scalability, accuracy,
   coverage, and performance and allows automated control loops to suit
   both today's and tomorrow's network operation.  This document
   clarifies the terminologies and classifies the modules and components
   of a network telemetry system from several different perspectives.
   To the best of our knowledge, this document is the first such effort
   for network telemetry in industry standards organizations.  The
   framework and taxonomy help to set a common ground for the collection
   of related work and provide guidance for future technique and
   standard developments.
