Hi,
I would realy like a preference to ignore duplicated packets (within a
*short* time of another) as for one
Extreme switches has the *feature* to duplicate packets on the mirroring
port in some circumstances.

loss

It is NOT a bug in the sense that currently it just applies the loss
calculation from RFC 3550 (RTP) by the letter (which has the property of
counting e.g. duplicate packets as negative losses).
Of course, we can always discuss wether this algorithm makes sense or
not and if we should for example count duplicate packets seperately.
Note however that there might be very complicated scenarios of
lost/duplicate/out of order packets.

br,
Lars Ruoff

A negative packet loss i thinks makes little or no sense as such it
might be a proportion of duplicates but that I think is a bug worth
being reported at http://bugs.ethereal.com

Max delta is the maximum time gap between two consecutive packets.
