Abstract

The research and application on Peer-to-Peer (P2P) is a topical issue in the present computer network field. The current P2P systems can be separated into two types. One is structured and the other non-structured. The Structured P2P system is based on the principle of DHT which aims to solve some of the problems which exist in the Chord Routing Algorithm. It is a representative structured P2P system. This thesis puts forward a scheme for improving the system. Based on the structural improvement mentioned, this thesis presents a PHFChord system which can improve the file availability and routing efficiency as well as increase the speed of the requiring resource file. In this thesis, the design of PHF Chord system is explained in detail, including the routing strategy, the joining of new nodes and exiting of old nodes.
