A new Request for Comments is now available in online RFC libraries. RFC 8468 Title: IPv4, IPv6, and IPv4-IPv6 Coexistence: Updates for the IP Performance Metrics (IPPM) Framework Author: A. Morton, J. Fabini, N. Elkins, M. Ackermann, V. Hegde Status: Informational Stream: IETF Date: November 2018 Mailbox: acmorton@att.com, joachim.fabini@tuwien.ac.at, nalini.elkins@insidethestack.com, mackermann@bcbsm.com, vinayakh@gmail.com Pages: 15 Characters: 35970 Updates: RFC 2330 I-D Tag: draft-ietf-ippm-2330-ipv6-06.txt URL: https://www.rfc-editor.org/info/rfc8468 DOI: 10.17487/RFC8468 This memo updates the IP Performance Metrics (IPPM) framework defined by RFC 2330 with new considerations for measurement methodology and testing. It updates the definition of standard-formed packets to include IPv6 packets, deprecates the definition of minimal IP packet, and augments distinguishing aspects, referred to as Type-P, for test packets in RFC 2330. This memo identifies that IPv4-IPv6 coexistence can challenge measurements within the scope of the IPPM framework. Example use cases include, but are not limited to, IPv4-IPv6 translation, NAT, and protocol encapsulation. IPv6 header compression and use of IPv6 over Low-Power Wireless Area Networks (6LoWPAN) are considered and excluded from the standard-formed packet evaluation. This document is a product of the IP Performance Measurement Working Group of the IETF. INFORMATIONAL: This memo provides information for the Internet community.
