| 英文摘要: |
| To enhance user perceived performance, Akamai’s content distribution network (CDN) utilizes the domain name system (DNS) effectively to redirect users to close-by content replicas over short time scale. The use of DNS redirection has brought a significant advantage to Akamai’s CDN. However, the reliance on DNS also poses a fundamental threat to Akamai’s content distribution model. In particular, systematic evaluation and quantification illustrates the impact of recent emerging public DNS resolving services on Akamai’s CDN, including the degradation of corresponding user perceived performance and the benefit damnification of collaborating internet services providers (ISPs) that host Akamai’s edge servers. The measurement demonstrates that a considerable penetration of public DNS resolving services (e.g., OpenDNS and GoogleDNS) effectively corrupts the Akamai’s serving model, namely the large-scale server distribution and quick DNS redirection. |
