                     A One-Way Loss Metric for IPPM
                      draft-ietf-ippm-2680-bis-04

Abstract

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

Status of This Memo
