Abstract

   This document provides an architectural framework for network
   telemetry to address the current and future network operation
   challenges and requirements.  The defining characteristics of network
   telemetry show a clear distinction from the conventional network
   Operations, Administration, and Management (OAM).  Network telemetry
   promises better scalability, accuracy, coverage, and performance and
   allows automated control loops to suit both today's and tomorrow's
   network operation requirements.  This document clarifies the
   terminologies and classifies the modules and components of a network
   telemetry system.  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.
