Neubot is a research project on network neutrality of the NEXA Center for Internet & Society at Politecnico di Torino. The project is based on a lightweight open-source program that interested users can download and install on their computers. The program runs in background and periodically performs transmission tests with some test servers and with other instances of the program itself. These transmission tests probe the Internet using various application level protocols. The program saves tests results locally and uploads them on the project servers. The collected dataset contains samples from various Providers and allows to monitor network neutrality.
