// BBR (BBSim Reflector) is a tool designed to scale test BBSim
// It shared most of the code with BBSim itself and replies to messages
// pretending to be VOLTHA.
// The idea behind it is that, given that the BBSim and BBR are based on the same
// codebase, BBR is acting as a wall for BBSim. And you can't beat the wall.
