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.
