VoIP Network Quality Tester

VoIP and Video calls are very sensitive to latency, jitter and packet loss in IP networks, but there aren’t many good end-user tools available to determine how good a network is. This project creates a probe that users can run on a standard end user device (e.g. desktop, tablet or smart phone) that communicates with a remote server and provides an indication of how good the network is and predicts the quality of calls through it. Ease of use is essential – both to install/run and presenting the results in a user friendly manner. Idea could be extended for example to crowd-sourcing across many users in order to build a much wider picture of the network, or to predict quality of a gaming connection.

Feedback: Very timely. However, students may not have suitable signal processing skills. Would this use separate audio hardware to inject and capture controlled signals, or rely on intercept of system audio? Would capture and analysis of video quality be an alternative?
