I don't have data on flows but I can say some data from our perspective;
On OC48 backbone interfaces, here:
- about 600 Mbit/s of traffic equals about 120 kpps
- a DoS attack of 1.2 Gbit/s was 150 kpps
- about 1200 Mbit/s of traffic equals about 150 kpps
A significant portion of these is large filetransfers, though (as the
average packet size is like 600-1000 bytes, calculated from above)...
