The goal of Web services is to solve the problem of communication protocols between Web’s applications. One of the main problems recurrent to Web Services is in the fact of the customer not to obtain the necessary QoS to receive or access determined service. This work presents an architecture to achieve QoS between Web Services. This architecture uses a broker as intermediate module between client, server and UDDI, collecting QoS information and making selection decisions for clients to achieve the QoS desired. This work presents the architecture proposed as main contribution, and a XML schema documents structure for the definition of the QoS parameters.
