-// 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]. |
