-// The purpose of BandwidthSmoother is to smooth out bandwidth
-// estimations so that 'trstate' messages can be triggered when we
-// are "sure" there is sufficient bandwidth.  To avoid frequent fluctuations,
-// we take a slightly pessimistic view of our bandwidth.  We only increase
-// our estimation when we have sampled bandwidth measurements of values
-// at least as large as the current estimation * percent_increase
-// for at least time_between_increase time.  If a sampled bandwidth
-// is less than our current estimation we immediately decrease our estimation
-// to that sampled value.
-// We retain the initial bandwidth guess as our current bandwidth estimation
-// until we have received (min_sample_count_percent * samples_count_to_average)
-// number of samples. Min_sample_count_percent must be in range [0, 1].
