A proxy-network based overlay topology resistant to DoS attacks and partitioning

In this paper we examine the effectiveness of a circulant graph proxy-network overlay topology. We select to examine a circulant graph that exhibits several attributes which strengthen the proxy network´s resistance to DoS attacks. Proxy networks enable applications to communicate with users without disclosing their IP´s. An application´s resistance to DoS attacks is improved by hiding it behind a proxy-network based overlay. We evaluate the selected-topology´s fault-tolerance and its effectiveness in the resistance of DoS attacks.
