Abstract: To deal with problems such as fast information retrieval, multi-replica synchronization and so on, a P2P model is presented for distributed collaborative design systems. Some function models, information retrieval models and so on are proposed to construct the system. A P2P information retrieval method based on DHT and interest clustering is used to ensure the fast retrieval of users. And a distributed mutual exclusion algorithm based on DHT is given as the method to synchronize the collaborative data. And the implement method and an instance system are given.
Key words:
