Push or Pull?: Toward Optimal Content Delivery

Video-over-IP applications are experiencing a momentous popularity increase via crowd-acceleration. Content delivery using distributed caching can alleviate high bandwidth demands of such applications. However, existing Content Distribution Networks (CDNs) are designed for relatively small web objects, and many prior efforts are mainly focused only on reducing user experienced latency. A few recent studies address the issue of bandwidth usage in CDNs. The authors argue that considering the bandwidth consumption together with delay performance is important for the emerging needs of videos of diverse object sizes and user perceived performance.
