Title : Cooperative Content Distribution and Traffic Engineering in a Provider Network

Traditionally, Internet Service Providers (ISPs) make profit by providing Internet
connectivity, while content providers (CPs) play the more lucrative role of delivering
content to users.  As network connectivity is increasingly a commodity, ISPs have a strong
incentive to offer content to their subscribers by deploying their own Content
Distribution Networks (CDNs).  Running both a CDN and the underlying network presents new
opportunities for coordination between server selection (to match servers with
subscribers) and traffic engineering (to select efficient routes for the traffic). In this
work, we utilize a mathematical framework to show that separating server selection and
traffic engineering leads to a sub-optimal equilibrium, even when the CDN is given
accurate and timely information about network conditions.  
Leveraging ideas from cooperative game theory, we propose that the system implements a
Nash bargaining solution that significantly improves the fairness and efficiency of the
joint system. This study is another step towards a systematic understanding of the
interactions between those who generate and distribute contents and those who provide and
operate networks.
