ndnSIM people may have better ways to get the values, but generally speaking one can get delay and thruput values from measuring the time gap between sending an interest and getting corresponding data packet back, right?
it is unclear to me whether hop count should be in the cost calculation, as it may not be well defined -- an interest can hit a cached copy at some router without reaching the original producer.
