               Simple Two-way Active Measurement Protocol
                        draft-ietf-ippm-stamp-00

Abstract

   This document describes a Two-way Active Measurement Protocol which
   enables measurement of both one-way and round-trip performance
   metrics like delay, delay variation and packet loss.
