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

Abstract

   This document provides an architectural framework for network
   telemetry to meet the current and future network operation
   requirements.  The defining characteristics of network telemetry show
   a clear distinction from the conventional network Operations,
   Administration, and Management (OAM) concept; hence network telemetry
   requires new procedures, methods, and protocols.  This document
   clarifies the terminologies and classifies the categories and
   components of a network telemetry framework.  The requirements,
   challenges, existing solutions, and future directions are discussed
   for each category.  The network telemetry framework and the taxonomy
   help to set a common ground for the collection of related works and
   put future technique and standard developments into perspective.
