                    draft-ietf-netconf-yang-push-11

Abstract

   Providing visibility into changes made on YANG configuration and
   operational objects enables new capabilities such as remote mirroring
   of configuration and operational state.  Via the mechanism described
   in this document, subscriber applications may request a continuous,
   customized stream of updates from a YANG datastore.
