is used for implementing a Bandwidth on Demand service as&nbsp;part of the GEANT project. This project was driven by the&nbsp;increasing demand for reliable and guaranteed data&nbsp;transportation for scientific purposes. In order to&nbsp;implement the process of information exchange in a multidomain&nbsp;heterogeneous environment several design decisions&nbsp;have to take place, in order to balance and satisfy by the&nbsp;needs of information security, fast information&nbsp;dissemination, efficient request processing, reliability and&nbsp;robustness. The paper describes how AutoBAHN&nbsp;implements a flexible AAI in a distributed environment,&nbsp;how it exchanges and updates information and how it&nbsp;handles incoming requests in an efficient and timely manner.&nbsp;The multi-domain aspect of this effort stems from the fact&nbsp;that the tool is used in the production environment of&nbsp;several cooperating National Research and Educational&nbsp;Networks (NRENs) across Europe. Each NREN may have&nbsp;different underlying technologies, different policies and&nbsp;different use cases, but they all have to coordinate through&nbsp;usage of the AutoBAHN tool in order to produce a multidomain&nbsp;service of circuit reservation.</p>
