NDT (Network Diagnostic Tool) Dataset

Raw Datasets 2009 – present

About this dataset

The NDT dataset contains measurements of TCP throughput and latency collected by the Network Diagnostic Tool (NDT). NDT is a single-stream performance measurement of a connection's capacity for bulk transport. Measurements include download speed, upload speed, round-trip time (RTT), and packet loss between end-user devices and M-Lab servers worldwide.
