PlanetLab has been widely used in the networking community to test and deploy user defined overlays. Serving as a meta testbed to support multiple overlay networks, PlanetLab has significantly lowered the barriers to build new overlays. However, PlanetLab users always face the problem of selecting a set of PlanetLab nodes and interconnecting them to form the desired overlay network. Unfortunately, such a task is usually carried out manually by individual users and sometimes in an ad-hoc manner. In this project, we develop NetFinder, an automatic overlay network configuration tool to efficiently locate PlanetLab resources to individual overlays. NetFinder continuously monitors the resource utilization of the PlanetLab and accepts the user defined overlay topology as inputs and selects the set of PlanetLab nodes and their interconnection for the user overlay.
The algorithm used by NetFinder is extended from the following work:
