Dear NANOG, One of my ongoing research works is about a transport protocol that ensures (critical) communication in spite of DDoS congestion attack (which cannot be circumvented), by (careful) use of Forward Error Correction. Yes, obviously, this has to be done and used carefully since the FEC clearly increases traffic rather than the typical congestion-control approach of reducing it, I'm well aware of it; but some applications are critical (and often low-bandwidth) so such tool is important. I am looking for data on loss rate and congestion of DDoS attacks to make sure we use right parameters. Any chance you have such data and can share?
