This smoothing is performed using N_EWMA[27], which is an Exponential Moving Average with alpha = 2/(N+1): - N_EWMA = BDP*2/(N+1) + N_EWMA_prev*(N-1)/(N+1). + N_EWMA = BDP*2/(N+1) + N_EWMA_prev*(N-1)/(N+1) + = (BDP*2 + N_EWMA_prev*(N-1))/(N+1). + +Note that the second rearranged form MUST be used in order to ensure that +rounding errors are handled in the same manner as other implementations. Flow control rate limiting uses this function. |
