  Test Plan and Results for Advancing RFC 2680 on the Standards Track

Abstract

   This memo provides the supporting test plan and results to advance
   RFC 2680, a performance metric RFC defining one-way packet loss
   metrics, along the Standards Track.  Observing that the metric
   definitions themselves should be the primary focus rather than the
   implementations of metrics, this memo describes the test procedures
   to evaluate specific metric requirement clauses to determine if the
   requirement has been interpreted and implemented as intended.  Two
   completely independent implementations have been tested against the
   key specifications of RFC 2680.
