域名系统（DNS）是当今互联网的基本组成部分。近年来，随着远程DNS和OpenDNS等公共DNS服务的使用量增加，DNS发生了根本性的变化。鉴于DNS和内容交付网络（CDN）之间的密切关系，以及CDN在包括Web浏览和实时娱乐服务在内的许多流行应用程序中的广泛使用，了解远程和公共DNS服务对用户整体Web体验的影响非常重要。这项工作提出了一个工具，namehelp，比较评估DNS服务的Web性能，他们提供的，并实现了一个终端主机解决方案，以解决远程DNS对CDN的性能影响。该演示将展示namehelp的功能及其性能改进的在线结果。
The Domain Name System (DNS) is a fundamental component of today's Internet. Recent years have seen radical changes to DNS with increases in usage of remote DNS and public DNS services such as OpenDNS. Given the close relationship between DNS and Content Delivery Networks (CDNs) and the pervasive use of CDNs by many popular applications including web browsing and real-time entertainment services, it is important to understand the impact of remote and public DNS services on users' overall experience on the Web. This work presents a tool, namehelp, which comparatively evaluates DNS services in terms of the web performance they provide, and implements an end-host solution to address the performance impact of remote DNS on CDNs. The demonstration will show the functionality of namehelp with online results for its performance improvements.
