My research deals with operational and economic issues relating to content delivery networks. I analyze critical issues in web based content delivery (e.g., proxy caching, content server location, capacity planning, etc.) with a focus on empirically validating models of improved content delivery with real web traffic data. I am also working on economic aspects of the problem, namely, the price a monopolistic content delivery provider should charge when faced with customers that can set up their own content distribution solutions. Of particular relevance in this analysis is to consider bursty models of web traffic and consider their implications on the optimal capacity of the content server.
