Traffic Localizing Strategy for Peer-to-Peer Systems

Topology mismatching problem between peer-to-peer overlay network and physical underlying network brings great stress to Internet infrastructure. This paper proposes a traffic localizing strategy (TLS), it keeps scalability property of current DHT algorithms and improves system routing performance by partitioning DHT key space associating with local physical information. Experiments based on CAN model show that the traffic localizing strategy can significantly alleviate the backbone link traffic burden. Meanwhile, the average routing hops are reduced.
