  1. IP Flow Information eXport (IPFIX) • Web Site: http://ipfix.doit.wisc.edu • Mailing list info: http://ipfix.doit.wisc.edu/#Mailing_List • Meeting slides, minutes will be available at: http://ipfix.doit.wisc.edu/IETF56/

  2. IPFIX WG Meeting, IETF 56 • Administrivia: scribe, attendance sheets, slides • http://ipfix.doit.wisc.edu/IETF56/ • Agenda Review, additions? (5 mins) • Requirements Draft (Juergen Quittek, 10 mins) • Evaluation Process: • Updates to Advocacy Drafts, (Benoit Claise, 10 mins) • Draft-claise-ipfix-eval-netflow-04 • Discussion: Evaluation Team's Selected Protocol (Chairs, 55 mins) • Review of WG Milestones (5 mins)

  3. IPFIX WG Meeting, IETF 56 • IPFIX-PSAMP relationship, (Benoit Claise, 10 mins) • draft-quittek-psamp-ipfix-01 • Measurement and Monitoring draft (Supratik Bhattacharyya, 15 mins) • Draft-ietf-monitoring-sprint-01 • "Requirements for integrating monitoring with operations,and thorny issues such as the problem of data export." • Wrap up

  4. IPFIX Evaluation Results • The evaluation team recommends using NetFlow v9 as a basis for the IPFIX protocol • Attempting to quantify evaluation in a compatibility matrix was a dead end. No significant new information has appeared since our last meeting. • Our charter directs us to specify an IPFIX system which is "amenable to router and instrumentation implementors, and to deployment."The team believes that the IPFIX protocol, based on NetFlow v9, can be implemented in the most network elements because it makes the least demands of the exporter.

  5. IPFIX Evaluation Results • Once we have consesus for NetFlow v9, via mailing list, the team suggests that the following should be addressed: • sub-second time-stamps • flow-loss statistics • clarify that exporter id isn't necessarily the transport source address (for proxying and fanouts) • Openness to reliability extensions per requirements • Fail-over, consider rserpool applicability draft: • Draft-coene-rserpool-applic-ipfix-00

  6. An IPFIX Implementation Proposal • Specify that the initial IPFIX transport be TCP • This is a transition mechanism to enable rapid development and deployment of IPFIX. • Why?Because TCP is the only ubiquitous standard Congestion-Controlled transport protocol. • However, the IPFIX protocol MUST NOT rely on TCP's reliable delivery. Instead, it MUST remain compatible with unreliable datagram delivery so that it can be ported to upcoming transport protocols such as DCCP or PR-SCTP.

  7. Next Steps • The chairs and evaluation team propose: • Simon Leinen's evaluation ID, with conclusions added, be adopted as the IPFIX Evaluation Report and submitted to IESG for publication as an Informational RFC • Draft-leinen-ipfix-eval-contrib-00 • An IPFIX protocol ID be prepared: • Draw details, but not content directly, from the NetFlow v9 advocacy draft • Do away with the advocacy draft in favor of this new protocol draft, ultimately intended to be proposed as standard • We'll need an editor for the protocol ID

  8. IPFIX WG Meeting, IETF 56Next Steps • IPFIX document roadmap: • IPFIX-ARCHITECTURE • Explains how IPFIX systems work • IPFIX-DATAMODEL • Enumerates and describes the IPFIX flow attributes • IPFIX-PROTOCOL • Describes the IPFIX protocol and encodings • IPFIX-APPLICABILITY • Describes typical uses of IPFIX systems • required for standards track
