QMC: A Service Registry Extension Providing QoS Support

With the rapidly growing number of Web services throughout the Internet, the limitations of centralized architecture and the neglect of QoS support have severely restricted service registriespsila ability to publish and discover Web services. We propose a P2P service registry extension named QMC to solve these problems. QMC provides comprehensive support on QoS such as storing QoS feedbacks, managing QoS data, handling QoS requests.Moreover QMC is a system with high scalability and load-balance.
