Defeating DDoS Attacks by Fixing the Incentive Chain

In this paper we discuss two components of the technologicalsolutions to DDoS attacks: cooperative filtering and cooperative traffic smoothing by caching. We then analyzethe broken incentive chain in each of these technological solutions. As a remedy, we propose usage-basedpricing and Capacity Provision Networks, which enable victims to disseminate enough incentive along attackpaths to stimulate cooperation against DDoS attacks.
