Because Chord is a typical distributed structured peer-to-peer (P2P) system based on overlay network, the distance between two adjacent peers may be very far on IP network, and the network access speed is greatly reduced. To solve the problem, a new P2P system is proposed to improve the Chord system. The peers in the same location are connected in a Location Area P2P Network (LAPN) which is connected by pointers. The method can resolve the problem and improve the system efficiency.
