  • To provide high quality streaming service, content distribution network (CDN) exploits the domain name system (DNS) to redirect users to the close-by content servers which are widely worldwide distributed. In recent years, the development of domain name system, especially the rising of IP Anycast based domain name system (e.g., Google Public DNS and Open DNS), will definitely impact the content distribution mechanism of CDN. Compared with other Internet services, streaming service requires relatively more network resource. The influence from DNS will be more obvious. This paper firstly states how IP Anycast based DNS impact the redirection of CDN networks, analyzes the factors that impact the QoS of streaming service, and finally compares the QoS of CDN streaming service when using different DNS resolving service.

Abstract: To provide high quality streaming service, content distribution network (CDN) exploits the domain name system (DNS) to redirect users to the close-by content servers which are widely worldwide distributed. In recent years, the development of domain name system, especially the rising of IP Anycast based domain name system (e.g., Google Public DNS and Open DNS), will definitely impact the content distribution mechanism of CDN. Compared with other Internet services, streaming service requires relatively more network resource. The influence from DNS will be more obvious. This paper firstly states how IP Anycast based DNS impact the redirection of CDN networks, analyzes the factors that impact the QoS of streaming service, and finally compares the QoS of CDN streaming service when using different DNS resolving service.
