The IESG has approved the following document: - 'IPFIX Mediation: Problem Statement ' <draft-ietf-ipfix-mediators-problem-statement-09.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-mediators-problem-statement-09.txt Technical Summary This document specifies an improvement to the PR-SCTP export specified in the IPFIX specifications in RFC5101. This method offers several advantages such as the ability to calculate Data Record losses for PR-SCTP, immediate export of Template Withdrawal Messages, immediate reuse of Template IDs within an SCTP stream, and reduced demands on the Collecting Process. Working Group Summary Flow-based measurement is a popular method for various network monitoring usages. The sharing of flow-based information for monitoring applications having different requirements raises some open issues in terms of measurement system scalability, flow-based measurement flexibility, and export reliability that IPFIX Mediation may help resolve. This document describes some problems related to flow-based measurement that network administrators have been facing, and then describes IPFIX Mediation applicability examples along with the problems. The WG reached consensus for publication. Document Quality The document underwent two WG last call in the IPFIX WG. Personnel Juergen Quittek is shepherding this document.
