Abstract

The Web is moving toward a collection of interoperating Web services. A critical factor to achieving this interoperability is a scalable, flexible and robust discovery mechanism. Yet, a centralized architecture has the limitations of single point failure and performance bottleneck. In order to solve this problem, this paper first proposes a distributed Web Service Discovery Infrastructure called Stratus, and then analyzes some key technologies such as Dynamic Tuple Model, topology constructing approach, unified publication and inquiry API etc. Furthermore, the simulation results show that, Stratus is scalable, well self-organized, and high efficient for service discovery.
