Abstract

This document refers to a metric for variation in delay of packets across Internet paths. The metric is based on the difference in the One-Way-Delay of selected packets. This difference in delay is called "IP Packet Delay Variation (ipdv)".

Abstract

   This document refers to a metric for variation in delay of packets

   across Internet paths.  The metric is based on the difference in the

   One-Way-Delay of selected packets.  This difference in delay is

   called "IP Packet Delay Variation (ipdv)".

   The metric is valid for measurements between two hosts both in the

   case that they have synchronized clocks and in the case that they are

   not synchronized.  We discuss both in this document.
