Abstract

A Model for Web Services Discovery With QoS SHUPING RAN CSIRO Mathematical and Information Sciences GPO Box 664, Canberra, ACT 2601, Australia Shuping.Ran@csiro.au ________________________________________________________________________ Web services technology has generated a lot interest, but its adoption rate has been slow. This paper discusses issues related to this slow take up and argues that quality of services is one of the contributing factors. The paper proposes a new Web services discovery model in which the functional and non-functional requirements (i.e. quality of services) are taken into account for the service discovery. The proposed model should give Web services consumers some confidence about the quality of service of the discovered Web services. Additional Key Words and Phrases: Web services discovery, quality of services, UDDI, UDDI extension, tModel, model. ________________________________________________________________________ 1. INTRODUCTION Web services technology is becoming increasingly popular because of its potential in many areas. It is a new type of components that can be invoked over the Internet. This presents a promising solution for addressing platform interoperability problems faced by system integrators. The flexibility of this new component type also facilitates service composition using existing Web services, promoting component re-use which has been a dream for the software engineering industry.
