A low-impact internal latency measurement tool for OpenAirInterface

5G should provide low latency transmissions for new services (e.g. Industry 4.0). The measurement of such latencies inside the access network is a challenge for which LatSeq is designed.

LatSeq is an open-source tool for fine-grained analysis of latency inside the OpenAirInterface base station.

This tool is composed of two parts, one to measure the passage of a packet in a layer and the other to rebuild the packet’s journey through the layers.

Available at This repository includes the OpenAirInterface module for LatSeq and the necessary scripts to process and analyse LatSeq traces.
