PlanetFlow: Maintaining accountability for network services

PlanetFlow is a network auditing service that maintains comprehensive, permanent accountability for all traffic generated by PlanetLab services, in accordance with common Internet practice and the terms of the PlanetLab Acceptable Use Policy. PlanetFlow audits the usage of PlanetLab network resources in order to facilitate the resolution of complaints, limit liability, and minimize problematic behavior. The current implementation of PlanetFlow consists of a low overhead flow classifier, an autonomously managed distributed database, and a publicly accessible Web interface. PlanetFlow currently processes up to 4 TB of generated traffic per day, and incurs negligible CPU and storage overhead.
