                  NETCONF Base Notifications for NMDA
               draft-wu-netconf-base-notification-nmda-00

Abstract

   NMDA introduces additional datastores for systems that support more
   advanced processing chains converting configuration to operational
   state.  Support the monitoring of the base system events pertaining
   to these datatores hasn't been discussed in Network Configuration
   Protocol (NETCONF) Base Notifications [RFC6470].  This document
   updates [RFC6470] to support the Network Management Datastore
   Architecture (NMDA) defined in [I-D.ietf-netmod-revised-datastores].

1.  Introduction

   [RFC6470] provides standard mechanisms to support the monitoring of
   the base system events within the NETCONF server.  Such mechanism
   allows a NETCONF client to receive notifications for some common
   system events (e.g., a change in NETCONF server capabilities, that
   may impact management applications.).

   This document updates Network Configuration Protocol (NETCONF) Base
   Notifications [RFC6470] to support the Network Management Datastore
   Architecture (NMDA) defined in [I-D.ietf-netmod-revised-datastores].
   Specifically, with NMDA, there are several additional datastores that
   are subject to system events.  Extensions are needed to indicate the
   affected datastore and affected phase (because it is no longer simply
   about <running>; there are now also (for example) <intended> and
   <operational>).

   The solution presented in this document is backwards compatible with
   [RFC6470].  This is achieved by only adding new top-level resources,
   and thereby leaving the semantics of all existing resources alone.

   Note that "push-change-update" notification and "push-update"
   notification defined in [I-D.ietf-netconf-yang-push] are not general
   purpose notifications. and used to send to the receivers of a
   subscription entire or a portion of datastore contents.  The solution
   presented in this document can work together with "push-change-
   update" notification and "push-update" notification defined in [I-
   D.ietf-netconf-yang-push] to indicate to yang push client fine
   granularity of data change metadata properties (e.g. who made
