Research On Key Technology Of Web Services Discovery Based On P2P

With the rapid development of Internet technology in recent years, Web service is becoming a new-emerging computing model in the area of distributed computing,It enables interoperation and seamless integration of applications realized on different platforms and implemented with various programming languages. With the growing number of web service available, it's becoming an important question to how to rapidly discover the services the requestors expect, and discovering a suitable web service is the fundamental precondition to implement web services reusing and composition. The traditional research on the discovery mechanism is based on the centralized model, which has several disadvantages, such as dependency on the server badly, efficiency bottleneck, single point of failure, less scalability and so on.The P2P has broken the traditional model of centralized network. Each node not only plays a role of server that provides the services but also plays a role of client that enjoys the services provided by other nodes. Combining P2P and web services together is method to solve the problems from the centralized web services discovery mechanism.This thesis mainly focuses on the model of web services discovery based on P2P:...
