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