Standardizing a Multi-Enclave Federated UDDI for Use in a Dynamic Service Oriented Architecture

In a Web-service oriented environment, the UDDI Registry is the element of middleware which supports service description and discovery; without such middleware it is not possible to operate. Within the net-centric environment, the state of networks from the perspective of the user may often be one of intermittent connectivity and limited bandwidth. The UDDI Registry specifications were developed in the context of an Enterprise model; the underlying tacit assumptions included good network connectivity and bandwidth and a reasonably stable network environment. However, Navy needs not only include CONUS-based applications that have continuous network connectivity, they also include net-centric and edge applications. The situation that has resulted involves one in which net-centric operational scenarios, which include service discovery queries, federation and de-federation of Registries and policy reconciliation and enforcement across federated registries, are not addressed in sufficient detail by the current set of specifications. As a result of IAI’s Phase 1 efforts, we have developed Protocol designs and associated software infrastructure designs which will support UDDI Registry Access in a net-centric environment. The Phase 2 effort is focused on implementation of protocols and software in a prototyping effort, and standards activity to contribute to the UDDI specifications in this area.
