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.
