Here we provide some answers to frequently asked questions about the project.
It is a PINOT node - a small Raspberry Pi-based device for network measurements, experiments, and data collection. These nodes are deployed in different places as a part of the PINOT project (https://pinot.cs.ucsb.edu).
We use these nodes for network measurements and experiments, such as pings to different locations, exploring Internet availability, measuring Quality of Experience, investigating local connection issues, etc.
No. This device has the same capabilities as a typical Internet user connected to Wi-Fi and doesn’t have any additional equipment. Besides that, only a small UCSB-based team has direct access to these devices and restricts all unauthorized access to them.
We use these devices for active measurements - watching YouTube videos (with cats, of course), initiating connections to different websites, and measuring latency and throughput of channels. This allows us to collect labeled datasets for better Machine Learning models and networking optimization.
Direct access to devices is provided only to persons mentioned as active participants on the team page. The indirect restricted access to submitting experiments to the nodes could be provided to networking researchers or teams.
The devices are managed by centralized software (SaltStack). Only the central server can remotely access the devices. Even in case of full physical access to one of the devices, an intruder cannot access centralized infrastructure or any other nodes.
