Distributed Content Delivery Networks

A content distribution network (CDN) is a globally distributed network of proxy servers deployed in multiple data centers. The goal of a CDN is to serve content to end-users with high availability and high performance. CDNs serve a large fraction of the Internet content today, including web objects (text, graphics and scripts), downloadable objects (media files, software, documents), applications (e-commerce, portals), live streaming media, on-demand streaming media, and social networks.

A. Bouillard and F. Baccelli started a collaboration with Virag Shah (Postdoc at the Inria-Microsoft Saclay center) on the analysis of delays in data clusters. Their focus is on the way delays scale with the size of a request and on the way delays compare under different policies for coding, data dissemination, and delivery. A paper on the matter is submitted.
