Abstract P2P traffic has brought serious impact on the bearer
network, and how to utilize network bandwidth has become a common concern
problem for the Internet Service Provider (ISP) and the P2P user. A
congestion distance and DHT based P2P traffic optimization method is proposed
in this paper. The P2P traffic optimization model imports both aims of the
ISP and the P2P user, and the cost of congestion and communication for links
is converted into congestion distance uniformly. A distributed scheme with
flow controllers and information collectors is realized where information
collectors are constructed to a Distributed Hash Table (DHT) overlay. The
traffic optimization application case using Bittorrent
is discussed, where node selection and choking algorithms are changed. The
experiment results show our optimization method can reduce the network
traffic of inter autonomous system (AS) substantially, and react to the
network congestion automatically, and then the win-win result for the ISP and
the P2P user is achieved. Keywords: P2P
