Slide 2

  • An Exporting Process is changed to export

IANA standard Information Elements rather than ‑ Enterprise Specific or NFv9-equivalent fields. ‑

  • The Collector needs to know that the new fields are

equivalent to the old ones, so it can process the old and new fields together.

  • How can that be done?

Problem to be solved

Slide 3

  • Equivalence is built in to the Collector

A Collector update is required for each field change.

  • Equivalence table is loaded into the Collector out-of-band

Requires manual intervention.

  • Collector automatically obtains update from manufacturer

Location must be fixed for ever. Collector must have external network access.

  • Collector automatically obtains update from IANA

Requires Enterprise-Specific information in IANA! Collector must have external network access.

Potential solutions

Slide 4

  • Equivalence table is sent to the Collector by Exporters

 Equivalence is immediately available  No software update required  No location or availability issues  Can be tested in lab / isolated networks

  • This document proposes a method for IPFIX Exporting

Processes to inform Collecting Processes of equivalent Information Elements, so that the Collecting Process can understand the equivalence and be enabled to process data across a change of Information Elements.
