An Architecture to Provide QoS in Web Services

The standards for composition, communication and discovery for Web Services constitute a framework with the goal of achieve interoperability. Even else, some problems, like QoS provisioment were not solved. This article presents an architecture for Web Services discovery with QoS support. This architecture relies in a broker as an intermediate component between the client, the server and the UDDI, what it facilitates the discovery for QoS-support Web Services. This work presents the architecture proposed as main contribution, and a XML schema documents defining the way as the QoS parameters must be specified, allowing to each client to specify distinct QoS parameters to each kind of service.
