The invention provides a peer-to-peer network management system and method. The method comprises the following steps: a management station interacts with finite peer nodes in a peer-to-peer network through agent to obtain the related information from the peer-to-peer network or peer nodes adopting the resource locate and discovery (RELOAD) protocol; the peer-to-peer network or peer nodes are set or a management command is given to the peer-to-peer network or peer nodes; and the peer-to-peer network or peer nodes can instantly report the related information such as performance or alarm, and the performance requirement of the system is ensured. Therefore, the effective monitoring, diagnosis, debugging and other managements of the peer-to-peer network can be realized, the management efficiency of the peer-to-peer network can be increased, the working performance of the management station can also be increased and the timely management of the peer-to-peer network can be finally ensured, thus the normal operation of the peer-to-peer network can be ensured.
