                    Telemetry Data Export capability
             draft-tao-netconf-data-export-capabilities-01

Abstract

   This document proposes a YANG module for telemetry data export
   capability which augments system Capabilities model and provides
   additional telemetry data export attributes associated with system
   capability for transport dependent capability negotiation.

1.  Introduction

   Notification capability model defined in [I-D.netconf-notification-
   capabilities] allows a client to discover a set of capabilities
   supported by the server (e.g., basic system capability and YANG-Push
   related capabilities) both at implementation-time and run-time.
   These "capabilities" permit the client to adjust its behavior to take
   advantage of the features exposed by the device.

   However pre-configuration for some transport specific parameters
   (e.g., transport protocol, encoding format, encryption by the client
   is still inevitable, which may cause unexpected failure and
   additional message exchange between client and server.

   This document proposes a YANG module for telemetry data export
   capability which augments System Capabilities model and provide
   additional data export attributes for transport dependent capability
   negotiation.

1.1.  Terminology
