The IESG contact persons are Mirja Kühlewind and Spencer Dawkins. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-ippm-6man-pdm-option/
Technical Summary To assess performance problems, measurements based on optional sequence numbers and timing may be enabled in packets of a particular flow using a new Destination Options Header. Such measurements may be interpreted in real-time or after-the-fact. This document gives a specification of the existing IPv6 Destination Option extension header, called the Performance and Diagnostic Metrics (PDM) Destination Option. The document also provides the field limits, calculations, and usage of the PDM in measurement. Working Group Summary After years of discussion, consideration, and revision, the working group adopted the draft and then moved smoothly to consensus in another year, aided by the implementation of the option in Free BSD. Document Quality As noted, this has been implemented in Free BSD. I'd note that the document has significantly benefited from the secdir review, performed by Tero Kivinen, and the Gen-ART review, performed by Jouni Korhonen. Thanks especially for that support. Personnel The document shepherd is Al Morton (was formerly Bill Cerveny). Spencer Dawkins is the responsible area director.
