Analysis of a JBI pub/sub architecture's infrastructure requirements

A Distributed Information Enterprise Modeling and Simulation (DIEMS) framework, presently under development, is applied to the analysis of a Joint Battlespace Infosphere (JBI) Pub/Sub architecture's infrastructural requirements. This analysis is an example of one methodology that can be employed utilizing the DIEMS framework. This analysis capability permits the information systems engineer to ensure that the planned JBI architecture deployment will provide the required information exchange performance on the infrastructure provided. This paper describes the DIEMS framework including its application in constrained and unconstrained resource utilization modes. A JBI architecture is evaluated in the context of a representative operational scenario on one infrastructure. The simulator's unconstrained resource mode is employed to identify the architecture's ideal operational requirements and in turn identify potential resource limitations. The constrained simulation mode is employed to evaluate the potential choke points in relation to the architecture's performance. The results identify the infrastructure changes required so that the specific JBI architecture will achieve the required operational performance.
