Peer-to-Peer(P2P) systems have been one of the hottest research issues for its attractive advantages, such as self-organizing, scalability and fault tolerance. However, super node failure is a serious problem because of the high dynamic and untrusted peers. A super node election mechanism is implemented, which included four basic components: The registration center module, group membership maintenance module, fault detector and super node election algorithm. The system constantly detects failure, at the same time, gathers the statistics of the online rate and fault detection message response t...
