        A One-Way Loss Metric for IP Performance Metrics (IPPM)

Abstract

   This memo defines a metric for one-way loss of packets across
   Internet paths.  It builds on notions introduced and discussed in the
   IP Performance Metrics (IPPM) Framework document, RFC 2330; the
   reader is assumed to be familiar with that document.  This memo makes
   RFC 2680 obsolete.
