 YANG Data Models for the IP Flow Information Export (IPFIX) Protocol,
         Packet Sampling (PSAMP) Protocol, and Bulk Data Export
           draft-boydseda-ipfix-psamp-bulk-data-yang-model-03

Abstract

   This document defines a flexible, modular YANG model for packet
   sampling (PSAMP) and bulk data collection and export via the IPFIX
   protocol.  This new model replaces the model defined in RFC 6728,
   "Configuration Data Model for the IP Flow Information Export (IPFIX)
   and Packet Sampling (PSAMP) Protocols".  All functionality modeled in
   RFC 6728 has been carried over to this new model.

   The YANG data models in this document conform to the Network
   Management Datastore Architecture (NMDA) defined in RFC 8342.

   This document obsoletes RFC 6728 (if approved).
