Ways to Measure the Delay in IP Networks

Abstract

The paper reviews various tools and methods for measuring the delay in IP networks. Methods for measuring of the jitter are also mentioned, as the jitter is an integral part of the delay, especially in real-time data transmission, such as VoIP. The one-way and two-way measurement methods of the delay are described. The protocols through which the one-way and two-way active measurements are realized and presented. Various tools for latency measurement are also presented. The use of Wireshark for measuring the delay and jitter in IP networks is presented.
