            UDP-based Transport for Configured Subscriptions
                    draft-unyte-netconf-udp-notif-00

Abstract

   This document describes an UDP-based notification mechanism to
   collect data from networking devices.  A shim header is proposed to
   facilitate the streaming of data directly from line cards to a
   collector.  The objective is to rely on a lightweight approach to
   allow for higher frequency and better transit performance compared to
   already established notification mechanisms.

Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].

1.  Introduction

   Sub-Notif [RFC8639] defines a mechanism that lets a collector
   subscribe to the publication of YANG-defined data maintained in a
   YANG [RFC7950] datastore.  The mechanism separates the management and
   control of subscriptions from the transport used to deliver the data.
   Three transport mechanisms, namely NETCONF transport [RFC8640],
   RESTCONF transport [RFC8650], and HTTPS transport
   [I-D.ietf-netconf-https-notif] have been defined so far for such
