Research of Peer-to-Peer network congestion
对等网络的拥塞研究

The wide use of Peer-to-Peer networks causes network congestion. Different from traditional research methods of network congestion, the topology of Peer-to-Peer networks was analyzed to understand network congestion. First, real traffic of Gnutella network was studied, and that the relationship between node's betweenness and the network congestion was found. A closed-form solution for network critical load was got by using queuing theory as the theoretical model. Finally, several schemes for relieving network congestion by augmenting the capacity of nodes with large betweenness and by adding assortative connections between those nodes were also proposed.
