Many different experimentation environments address complementary aspects of network protocol evaluation, but because of their disparities and complexities it is often hard to use them to reproduce the same experiment scenario. NEPI, the Network Experimentation Programming Interface, was created to make evaluation of network protocols and applications(More)
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 customization 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)
