Abstract
UDDI, Universal Description, Discovery, and Integration, represents a directory for the publication and querying of categorized Web services. Publication and query are performed by utilizing UDDI’s Application programming interface (API), which employs SOAP as a communication instrument.
By offering an invocation API in addition to two other types for examination, UDDI allows clients to search for and subsequently invoke specific Web services. Failures in invoking already sought and, on the application side, statically cached Web services typically result in re-querying the registry.
However, an application’s reaction time in response to changes is limited due to UDDI’s replication latency, i.e. the amount of time it takes for changes to entries stored inside the UDDI repository to be propagated to all UDDI nodes.
This paper proposes a mechanism termed active UDDI, which allows the extension of UDDI’s invocation API in order to enable fault-tolerant and dynamic service invocation.
