In this paper we investigate the interdomain connectivity of PlanetLab nodes. We note that about 85 percent of the hosts are located within what we call the Global Research and Educational Network (GREN) — an interconnected network of high speed research networks such as Internet2 in the USA and Dante in Europe. Since traffic with source and destination on the GREN is very likely to be transited solely by the GREN, this means that over 70 percent of the end-to-end measurements between PlanetLab node pairs represent measurements of GREN characteristics. We suggest that it may be possible to systematically choose the placement of new nodes so that as the PlanetLab platform grows it becomes a closer and closer approximation to the Global Internet.
