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

� � 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.
