A paper describing our experiences operating PlanetLab over the past six years, and in particular, how we resolved disputes involving PlanetLab experiments, is now available (here) for review and comment.

PlanetLab is a global research network that supports the development of new network services. Since the beginning of 2003, more than 1,000 researchers at top academic institutions and industrial research labs have used PlanetLab to develop new technologies for distributed storage, network mapping, peer-to-peer systems, distributed hash tables, and query processing.

PlanetLab currently consists of 938 nodes at 457 sites.
