[e2e] How to estimate packet loss?

[Chua Hong Nung]

Hi,
In TFRC it is suggested that loss event fraction models TCP more
accurately than loss fraction does. However I am quite confuse of how to
estimate packets in a loss interval. Given this data packets, would someone
please tell me how to estimate packets in a loss interval.

packets sent: 1   2   3   4(loss) 5(loss) 6   7   8   9   10   11   12
13(loss) 14(loss) 15(loss) 16   17   18   19   20   21(loss)   22   23   24

interval1 = 13 - 6  or interval1 = 13 - 4  ?
interval2 = 21 - 16 or interval2 = 21 - 13  ?

Thank you.

Chua
