The IESG has approved the following document: - 'Reducing Redundancy in IP Flow Information Export (IPFIX) and Packet Sampling (PSAMP) Reports ' <draft-ietf-ipfix-reducing-redundancy-04.txt> as an Informational RFC This document is the product of the IP Flow Information Export Working Group. The IESG contact persons are Dan Romascanu and Ron Bonica. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-ipfix-reducing-redundancy-04.txt Technical Summary This document describes a bandwidth saving method for exporting flow or packet information using the IP Flow Information Export (IPFIX) protocol. As the 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. Working Group Summary The WG discussed various ways to reduce redundancy in IPFIX records, and has reached consensus on this document. This document does not require any changes to the IPFIX Protocol or Information Model. Protocol Quality This document has been reviewed by by the IPFIX and PSAMP Working Group Chairs. Although it is an informational document the WG chairs required for an IETF Last Call to be conducted, in order to make sure that the content of the document refelcts the IETF community consensus. The document was reviewed for the IESG by Dan Romascanu.
