PlanetLab testbed is widely used to evaluate protocols and applications under realistic Internet conditions, but this realism comes at the cost of uncontrolled topology and traffic behavior. The use of overlay networks on PlanetLab can solve this problem by giving more control to the experimenter. However, manually creating such overlays is far from simple,(More)
We present the extensions made to NEPI, the Network Experimentation Programming Interface, to allow easy creation and cus-tomization of routing overlays on top of PlanetLab. We particularly focus on demonstrating the traffic shaping capabilities provided by NEPI, with the use of customizable stream filters on PlanetLab overlays to induce controllable packet(More)
