Dear all,
I am performing some experiments with DCCP/TFRC. Therefore, I'm using the
DCCP implementation of Mattsson. My question relates to the calculation of
the average loss interval as it is done by this implementation. As
specified the TFRC RFC, the 8 most recent loss intervals are used to obtain
the average loss interval. However, also when the first loss event occurs
and in every situation where the number of initialized loss intervals is
strictly smaller than 8, this implementation takes the sum W_{tot} of all 8
weights and uses this result to determine the average loss interval.
I would assume that when the loss history contains only two loss intervals,
it is sufficient to take only these weights into account when calculating
W_{tot}. This would not result in an overestimate of the loss event rate
you get by taking into account the total of the 8 weights.
Can anyone confirm that the number of weights you need to use to obtain the
average loss interval equals the minimum of 8 and the number of the actually
created loss intervals?
Best Regards,
Jeroen
