  Distributed denial of service (DDoS) attacks are a constant threat for
services in the Internet. This year, the record for the largest DDoS attack
ever observed was set at 1.7 Tbps. Meanwhile, detection and mitigation
mechanisms are still lacking behind. Many mitigation systems require the
assistance by the victim - or the victim's administrator themself has to become
active to mitigate attacks. We introduced a system that can detect attacks,
identify attackers, and mitigate the attacks purely within the network
infrastructure. With the improved flexibility of software-defined networks, new
possibilities to mitigate such attacks can be implemented. In addition to our
short paper on the mitigation of reflective DDoS attacks on LCN 2018, we also
like to demonstrate our work on mitigating flooding attacks presented at LCN
2017 and our mitigation of slow DDoS attacks. In our demo, we show how these
systems can be combined and how they work when faced with such different
attacks.
