The IP Flow Information Export (ipfix) working group in the Operations and Management Area of the IETF has been rechartered. For additional information, please contact the Area Directors or the working group Chairs. IP Flow Information Export (ipfix) --------------------------------------------------- Current Status: Active Working Group Chairs: Nevil Brownlee (n.brownlee@auckland.ac.nz) Juergen Quittek (quittek@netlab.nec.de) Operations and Management Area Directors: Dan Romascanu (dromasca@avaya.com) Ronald Bonica (rbonica@juniper.net) Operations and Management Area Advisor: Dan Romascanu (dromasca@avaya.com) Mailing Lists: General Discussion: ipfix@ietf.org To Subscribe: http://www.ietf.org/mailman/listinfo/ipfix Archive: http://www.ietf.org/mail-archive/web/ipfix Description of Working Group: The IPFIX working group has specified the Information Model (to describe IP flows) and the IPFIX protocol (to transfer IP flow data from IPFIX exporters to collectors). Several implementers have already built applications using the IPFIX protocol. As a result of a series of IPFIX interoperability testing events the WG has produced guidelines for IPFIX implementation and testing as well as recommendations for handling special cases such as bidirectional flow reporting and reducing redundancy in flow records. Practical experiences with IPFIX implementations exposed new requirements for the IPFIX protocol that so far have not been addressed by the WG. The major current goal of the WG is developing solutions that meet the new requirements without modifying the core IPFIX protocol specifications. 1. The IPFIX WG has developed a MIB module for monitoring IPFIX implementations. Means for configuring these devices have not been standardized yet. The WG will develop an XML-based configuration data model that can be used for configuring IPFIX devices and for storing, modifying and managing IPFIX configurations parameter sets. This work will be performed in close collaboration with the NETCONF WG. 2. First applications of IPFIX at large operator networks showed the need for mediation of flow information, for example, for aggregating huge amounts of flow data and for anomymization of flow information. The IPFIX WG will investigate this issue and produce a problem statement and a framework for IPFIX flow mediation. 3. The PSAMP WG has developed a protocol for reporting observed packets. The PSAMP protocol is an extension of the IPFIX protocol. The IPFIX WG will develop a MIB module for monitoring PSAMP implementations. The new MIB module will be an extension of the IPFIX MIB module. 4. Anonymization of flow information has been identified as a requirement for flow information export already in RFC 3917. However, technologies for flow anonymization are still a research issue and have so far not been considered to be mature enough for standardization. As one step in this direction, the IPFIX WG will develop guidelines for the implementation of anonymized data export and storage over IPFIX and define an information model for configuring and reporting anonymization applied at IPFIX devices. 5. The IPFIX and PSAMP WGs have defined standards for selecting observed IP packets and collecting information in flow records. In order to reduce the amount of data to be processed, packet selection methods have been defined. Another method for reducing flow data is flow selection. The IPFIX WG will define methods for flow selection and provide an information model for configuring and reporting flow selection applied at IPFIX devices. 6. Being designed for the export of flow records the IPFIX protocol provides very limited means for structuring information elements within IPFIX records. With the increasing number of IPFIX applications there is a need for exporting more complex information. The IPFIX WG will develop an extension of the IPFIX protocol that supports hierarchically structured data and lists (sequences) of Information Elements in data records.
