| Abstract | Content delivery networks (CDNs) handle dissemination of large content objects over the Internet. CDNs can improve content reachability for content that cannot be cached at proxy servers. Examples include streaming content, dynamic content, and security content. However, there are some challenges when dealing with CDNs, such as disseminating content to multiple servers located in predefined places and the high cost of maintaining hardware. This consumes a great deal of energy and resources, especially in the context of video content distribution. Hence, this study proposes a novel idea to enhance video delivery in CDNs that utilizes the resources available at the user’s premises (e.g., set-top-boxes) to share content using Peerto-Peer transfers among nearby users. The use case I consider for this study is Facebook multimedia content delivery. I build upon Facebook’s existing Akamai CDN infrastructure. With this approach, end users can access content offline highly efficiently. Low delay and latency are also important factors from the end user’s perspective. Moreover, it is possible to deliver globally unpopular but locally popular content among set of users with less involvement of ISPs and CDN providers than would otherwise be possible. This approach allows content providers to deliver their content very efficiently and effectively at low cost. Yet another benefit of the work described in this study is to reduce the energy consumption of intermediary nodes while providing better service to end users |
