                    Subscription to YANG Datastores
                    draft-ietf-netconf-yang-push-24

Abstract

   This document describes a mechanism that allows subscriber
   applications to request a continuous and customized stream of updates
   from a YANG datastore.  Providing such visibility into updates
   enables new capabilities based on the remote mirroring and monitoring
   of configuration and operational state.
