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).
