A Flexible, Protocol-agnostic Latency Measurement Platform

Latency is one of the key parameters of any networked system, from vehicular networks to real time video streaming. Being capable of measuring such a parameter can be very important in assessing the performances of devices under test. In this paper, we discuss how we designed a lightweight, flexible, custom latency measurement protocol, LaMP, completely agnostic of lower-layer protocols. We also present the first open source tool leveraging LaMP, called LaTe, running on any Linux-based device, which has been validated through several tests, both involving general purpose laptops and embedded devices for vehicular communications, for which the most important results are presented.
