              Reporting Metrics: Different Points of View
                  draft-ietf-ippm-reporting-metrics-08

Abstract

   Consumers of IP network performance metrics have many different uses
   in mind.  The memo provides "long-term" reporting considerations
   (e.g, days, weeks or months, as opposed to 10 seconds), based on
   analysis of the two key audience points-of-view.  It describes how
   the audience categories affect the selection of metric parameters and
   options when seeking info that serves their needs.

Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].
