I know how huge this can be, but I think its now time to go forward and to
find a global solution to STOP this definively or at leave know how to stop
when it occurs...
You need a driving license to dirve on the road, but we have no 'laws' on
the net... I know the internet is considered as free, open, etc... but I m
sure we all agree that we need to find a solution... a good starting point
would be the IXPs we have. Paolo, Andre, what are you peak bandwidth on
your IX switches? Is ther any technical way to collect datas?

Problem with netflow is, that in a case of a ddos you need enourmous
bandwith to the
collector, and probably thw traffic to the collector is worst than the ddos
...
(only my expirience) you should be able to collect the traffic at each
location seperatly ...
but that's kint of invertment intensive ...

That would be a great thing ...

Yes, I can observe that too ...
