A non-cooperative active measurement technique for estimating the average and variance of the one-way delay

Abstract

Active measurements are a useful tool for obtaining a variety of Internet metrics. One-way metrics, in general, require the execution of processes at the remote machine and/or machines with synchronized clocks. This work proposes a new algorithm to estimate the first two moments of the one-way delay random variable without the need to access a target machine and to have the machine clocks synchronized. The technique uses the IPID field information and can be easily implemented using ICMP Echo request and reply messages. © IFIP International Federation for Information Processing 2007.
