CPCDN: Content Delivery Powered by Context and User Intelligence

Abstract— CPCDN: Content Delivery Powered by Context and User Intelligence. An unprecedented trend that content providers < Final Year Projects 2016 > are building their own content delivery networks (CDNs) to provide a variety of content services to their users. By exploiting powerful CP-level information in content distribution, these CP-built CDNs open up a whole new design space and are changing the content delivery landscape. In this paper, we adopt a measurement-based approach to understanding why, how, and how much CP-level intelligences can help content delivery. We first present a measurement study of the CDN built by Tencent, a largest content provider based in China. We observe new characteristics and trend sin content delivery which pose great challenges to the conventional content delivery paradigm and motivate the proposal of CPCDN, a CDN powered by CP-aware information.
