 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-01

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 is an alternative to 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 model in this document conforms to the Network
   Management Datastore Architecture (NMDA) defined in RFC 8342.

   This document obsoletes RFC 6728 (if approved).
