P2P Routing Algorithm Based on Physical Location and Access Locality

Aiming at the current structured P2P system’s locality of physical location and accessing resources, this paper takes the current popular structured P2P system Pastry as a foundation, proposes a P2P routing algorithm and gives relevant topology. When routing, the node route to the nodes which are physical adjacent to it. Theory analysis and the experimental results show that the algorithms proposed in this paper have improved the performance of P2P system about routing delays and the length of the path.
