Network Telemetry Framework
draft-ietf-opsawg-ntf-00
Abstract
This document provides an architectural framework for network
telemetry to address the current and future network operation
challenges and requirements. As evidenced by the defining
characteristics and industry practice, network telemetry covers
technologies and protocols beyond the conventional network
Operations, Administration, and Management (OAM). Network telemetry
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.
Status of This Memo
This Internet-Draft is submitted in full conformance with the
provisions of BCP 78 and BCP 79.
Internet-Drafts are working documents of the Internet Engineering
