Defending Network-Based Services Against Denial of Service Attacks
... Over the last decade, several value-added services have been proposed for deployment in the Internet. These include multicast communication [1], quality-of-service support [2], content distribution networks [3], and denial-of-service (DoS) defense mechanisms [4]. These services provide users with an ...
