  Configuration Data Model for the IP Flow Information Export (IPFIX)
                 and Packet Sampling (PSAMP) Protocols

Abstract

   This document specifies a data model for the IP Flow Information
   Export (IPFIX) and Packet Sampling (PSAMP) protocols.  It is for
   configuring and monitoring Selection Processes, Caches, Exporting
   Processes, and Collecting Processes of IPFIX- and PSAMP-compliant
   Monitoring Devices using the Network Configuration Protocol
   (NETCONF).  The data model is defined using UML (Unified Modeling
   Language) class diagrams and formally specified using YANG.  The
   configuration data is encoded in Extensible Markup Language (XML).
