Abstract

A method and a system for measuring one-way delay variation in a network transmits probe packets with a transmission time indication and a sequence number. The network receives a first probe packet and a second probe packet and notes their arrival times. If the two probe packets are sequential, the one-way delay variation is calculated between the two probe packets. The delay variation is equal to the difference in arrival time between the first and second probe packets minus the difference in the transmission time between the first and second probe packets.
