摘要: Web services provide a loosely coupled paradigm for distributed processing. But the traditional discovery mechanism is based on centralized UDDI, which lead to performance bottlenecks if large number of clients visit it and there also potential single-point fault. To achieve high scalability efficiency, decentralized approach P2P can be used. Combining together solve UDDI problems. In this paper, novel architecture taking into account QoS characteristics has two layers. The main registry peers in top layer form DHT system basic Chord algorithm. lower topology, some registered node unstructured topology.
