Subscribing to YANG datastore push updates
draft-ietf-netconf-yang-push-01.txt
Abstract
This document defines a subscription and push mechanism for YANG
datastores. This mechanism allows client applications to request
updates from a YANG datastore, which are then pushed by the server to
a receiver per a subscription policy, without requiring additional
client requests.
