Abstract
A content delivery network (CDN) refers to a geographically distributed network of web servers, aiming to enhance the website performance and reliability, i.e., providing fast delivery of the Internet content. CDN is often part of a mature enterprise level network, but due to the distributed nature, CDN may be vulnerable to a distributed denial-of-service attack (DDoS), in which the cyber-attackers try to flood the victim with overloaded traffic or requests. In the literature, the impact of DDoS on CDN has not been widely studied. Motivated by this challenge, in this work, we emulate a CDN environment and investigate the effect of a particular DDoS attack on the environment. It is found that free CDN clusters could be destroyed by only several Gigabyte traffic. In the end, we also discuss some potential solutions to help defend against DDoS attacks.
