On Multi-Point, In-Network Filtering of Distributed Denial-of-Service Traffic

In this paper, we model the existing two main categories of in-network DDoS defense algorithms (PushBack, SourceEnd) and propose a new type of algorithm (StrategicPoints). In particular, we compare their effectiveness in minimizing the amount of DDoS traffic that the victim receives, their impact on reducing the DDoS traffic on the entire Internet, and their resiliency against intelligent adversaries and dynamic attacks. We detail how the comparison results vary according to parameters and provide our insights on the pros and cons of these three categories of in-network DDoS defense solutions.
