"Architecture for IP Flow Information Export", Ganesh Sadasivan, 10-Sep-06. ( bytes)

This memo defines the IP Flow Information eXport (IPFIX) architecture for the selective monitoring of IP flows, and for the export of measured IP flow information from an IPFIX device to a collector.

"IPFIX Applicability", Tanja Zseby, 3-Jul-07. ( bytes)

In this document we describe the applicability of the IP Flow Information Export (IPFIX) protocol for a variety of applications. We show how applications can use IPFIX, describe the relevant information elements (IEs) for those applications and present opportunities and limitations of the protocol. We furthermore describe relations of the IPFIX framework to other architectures and frameworks.

"Reducing Redundancy in IP Flow Information Export (IPFIX) and Packet Sampling (PSAMP) Reports", Elisa Boschi, 21-May-07. ( bytes)

This document describes a bandwidth saving method for exporting flow or packet information using the IP Flow Information Export (IPFIX) protocol. As the Packet Sampling (PSAMP) protocol is based on IPFIX, these considerations are valid for PSAMP exports as well. This method works by separating information common to several flow records from information specific to an individual flow record. Common flow information is exported only once in a data record defined by an option template, while the rest of the specific flow information is associated with the common information via a unique identifier.

"Guidelines for IP Flow Information eXport (IPFIX) Testing", Carsten Schmoll, Paul Aitken, Benoit Claise, 16-Apr-08. ( bytes)

This document presents a list of tests for implementers of IP Flow Information Export (IPFIX) compliant Exporting Processes and Collecting Processes. This document specifies guidelines for a series of tests that can be run on the IPFIX Exporting Process and Collecting Process in order to probe the conformity and robustness of the IPFIX protocol implementations. These tests cover all important functions, in order to gain a level of confidence in the IPFIX implementation. Therefore they allow the implementer to perform interoperability or plug tests with other IPFIX Exporting Processes and Collecting Processes.

"Definitions of Managed Objects for IP Flow Information Export", Thomas Dietz, Atsushi Kobayashi, Benoit Claise, 14-Jul-08. ( bytes)

This document defines managed objects for IP Flow Information Export (IPFIX). These objects provide information for monitoring IPFIX Exporters and IPFIX Collectors including the basic configuration information.

"An IPFIX-Based File Format", Brian Trammell, Elisa Boschi, Lutz Mark, Tanja Zseby, Arno Wagner, 14-Jul-08. ( bytes)

This document describes a file format for the storage of flow data based upon the IPFIX Message format. It proposes a set of requirements for flat-file, binary flow data file formats, then applies the IPFIX message format to these requirements to build a new file format. This IPFIX-based file format is designed to facilitate interoperability and reusability among a wide variety of flow storage, processing, and analysis tools.

"Exporting Type Information for IPFIX Information Elements", Elisa Boschi, Brian Trammell, Lutz Mark, Tanja Zseby, 14-Jul-08. ( bytes)

This document describes an extension to IPFIX to allow the encoding of IPFIX Information Model properties within an IPFIX Message stream. This enables the export of extended type information for enterprise- specific Information Elements, facilitating interoperability and reusability among a wide variety of applications and tools.

"IPFIX Mediation: Problem Statement", Atsushi Kobayashi, Haruhiko Nishida, Christoph Sommer, Falko Dressler, Emile Stephan, Benoit Claise, 26-Sep-08. ( bytes)

Flow-based measurement is currently a popular method for various network monitoring usages. The sharing of flow-based information among orthogonal monitoring applications raises open issues in terms of scalability, reliability and flexibility that IPFIX Mediation may help resolve. IPFIX Mediation reroutes, replicates, filters, aggregates, correlates or modifies Flow Records or Packet Reports, or changes a transport protocol. This document describes the applicability of IPFIX Mediation and the problems that IPFIX Mediation might encounter.

"IPFIX Mediation: Framework", Atsushi Kobayashi, Haruhiko Nishida, Benoit Claise, 30-Jun-08. ( bytes)

This document describes a framework for an IPFIX Mediation. An IPFIX Mediation device (IPFIX Mediator) is an intermediate device between IPFIX Exporters and IPFIX Collectors. This framework describes an architecture model, the components of the architecture, and guidelines for the IPFIX protocol specifications for the IPFIX Mediators. In addition, this document describes applicable examples for IPFIX Mediation.

"IPFIX Export per SCTP Stream", Benoit Claise, Paul Aitken, Andrew Johnson, Gerhard Muenz, 1-Jul-08. ( bytes)

This document specifies an improvement to the use of SCTP as specified in the IPFIX specifications in order to be able to deduce the Data Record loss per Template Record in case of partially-reliable SCTP export. This specification offers several extra advantages: immediate export of the Template Withdrawal Message, immediate reuse of Template ID within a stream, and the Collecting Process's job is easier.

"Configuration Data Model for IPFIX and PSAMP", Gerhard Muenz, Benoit Claise, 4-Jul-08. ( bytes)

This document specifies a data model for the configuration of caches, selection processes, exporting processes, and collecting processes of IPFIX and PSAMP compliant monitoring devices. The configuration data model is encoded in Extensible Markup Language (XML). The structure of the data model is specified in a YANG module to ensure compatibility with the NETCONF protocol. A YANG-to-XSD converter is available which allows generating an XML Schema Definition (XSD) of the data model.
