          Partial Lock Remote Procedure Call (RPC) for NETCONF

Abstract

   The Network Configuration protocol (NETCONF) defines the lock and
   unlock Remote Procedure Calls (RPCs), used to lock entire
   configuration datastores.  In some situations, a way to lock only
   parts of a configuration datastore is required.  This document
   defines a capability-based extension to the NETCONF protocol for
   locking portions of a configuration datastore.

1.  Introduction

   The [NETCONF] protocol describes the lock and unlock operations that
   operate on entire configuration datastores.  Often, multiple
   management sessions need to be able to modify the configuration of a
   managed device in parallel.  In these cases, locking only parts of a
