We show on a simple network scenario that energy can be saved using off-the-shelf equipment not explicitly designed for dynamic on/off operation. No packet loss is experienced in our experiments. We indicate the \nneed for faster access to routers in order to perform the reconfiguration. This is particularly important for the more sophisticated energy saving approaches such as DUFL, since FUFL can be implemented locally.","claims":[{"public_id":"cl_3c25b8630ced0e3e0feca08396911f48","status":"active","text":"Faster access to routers is needed to perform the reconfiguration required by the more sophisticated
