| Summary: | With service-oriented environments, the real-time acquisition of new software functions relies on dynamic service discovery with the Universal Description, Discovery and Integration (UDDI) protocol. Both the fluidity of services and updates in service offerings affect service users via access operations of service data in registry repositories conformed to the protocol. One valuable usage of UDDI-specific systems is to guarantee real time responses to service enquiries with the service data that reflects the most updated information of services. In this paper, we present a federated UDDI system for service-oriented environment within an enterprise or organization boundary. Its distributed architecture allows the system to easily process data process requirements from service providers and users in a correlated and synchronized way. The system is designed with a special support of concurrent access to service data. We describe the synchronization technology used in the system that is based on optimistic timestamp-ordering. Our simulation tests validate the effectiveness of service data access with our federated UDDI registry system. |
