NETCONF Event Notifications
Status of This Memo
This document specifies an Internet standards track protocol for the
Internet community, and requests discussion and suggestions for
improvements. Please refer to the current edition of the "Internet
Official Protocol Standards" (STD 1) for the standardization state
and status of this protocol. Distribution of this memo is unlimited.
Abstract
This document defines mechanisms that provide an asynchronous message
notification delivery service for the Network Configuration protocol
(NETCONF). This is an optional capability built on top of the base
NETCONF definition. This document defines the capabilities and
operations necessary to support this service.
