Exploring the correlation between P2P applications and network architecture

Nowadays, P2P applications dominate most of the network traffic and the access pattern poses a serious problem. While some P2P connections are formed within an ISP (or organization), most P2P connections are connected to the rest of the internet, at a high cost to the site. In this paper, we would like to study the topic on how different network architectures (i.e., asymmetric vs. symmetric network) influence the network traffic and the user behaviors with the peer-to-peer (P2P) applications. Many mechanisms could be adopted for improving the network performance of the site.
