An Extension to UDDI for the Discovery of User Driven Web Services

Abstract

Service registries are used by web service providers to publish services and registries are used by requestors to find them in an SOA (Service Oriented Architecture). The following drawbacks are presented in the main existing service registry specifications, UDDI (Universal Description, Discovery and Integration). First, only abstract, unscalable and inefficient definition of the web services publications is present in all UBR (Universal Business Registry) nodes. Second, it matches only the business name and service name given in the WSDL document to collect service information. In order to overcome these difficulties, author have proposed an efficient and effective UDDI architecture called E-UDDI, which extends the UDDI design by incorporating a QoS in additional bag in the business entity data structure. Moreover, to enable service customer for easily finding more appropriate service information, an effective service matching mechanism is adopted in the E-UDDI so that the user can take the decisions. Service discovery and publishing is improved considerably in the proposed system by means of an effective UDDI registry with flexible and more suitable service searching facility.
