  • Publication number: 20080098121
    Abstract: A P2P SIP enabled multimedia network communication system is disclosed. The network communication system supports various application, such as IP-based audio, video and instant messages. The network communication system comprises a P2P network and a plurality of user terminals. The P2P network comprises a plurality of ADs acting as nodes thereof. Each of the user terminals is connected to the P2P network by an access AD thereof. The AD comprises a SIP interface, an adapter module and a DHT module. The adapter module performs the transfer between the SIP protocol and the P2P protocol. The DHT module performs a registration operation and look up operation based on a P2P message, and returns the result to the adapter module. The registration operation is used to save registration information of the user terminal in the P2P network.
