Peer management server and peer management method in a P2P system

摘要

A peer management server in a P2P system is disclosed. The peer management server comprises: a front-end processing unit which sets a connection with peers that access the P2P system, receives a message from the peers, and generates a query name and parameter corresponding to the received message so as to process the message; a SQL map processing unit which includes mapping information to map the query name and parameter to a query, and outputs the query corresponding to the query name and parameter received from the front-end processing unit; and a peer database which maintains information of the peers operated as active peers, and content information stored in each of the peers, and updates or extracts data based on the query outputted from the SQL map processing unit.
