                      Network Telemetry Framework
                        draft-ietf-opsawg-ntf-01

Abstract

   This document provides an architectural framework for network
   telemetry to address the current and future 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), so it promises
   better flexibility, 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.
