A. Morton: AUTHOR


The IP Performance Metrics (IPPM) framework [RFC2330] describes several ways to record options and metric parameter settings, in order to account for sources of measurement variability. For example, Section 13 of [RFC2330] describes the notion of "Type P" so that metrics can be specified in general, but the specifics (such as payload length in octets and protocol type) can replace P to disambiguate the results.

    RFC 4148 and the IP Performance Metrics (IPPM) Registry of Metrics                               Are Obsolete


   This memo reclassifies RFC 4148, "IP Performance Metrics (IPPM)    Metrics Registry", as Obsolete, and withdraws the IANA IPPM Metrics    Registry itself from use because it is obsolete.  The current    registry structure has been found to be insufficiently detailed to    uniquely identify IPPM metrics.  Despite apparent efforts to find    current or even future users, no one responded to the call for    interest in the RFC 4148 registry during the second half of 2010.
