Interface for scalable DEVS and distributed container object specifications

In this paper, we present two specifications, scalable DEVS specification and distributed container object specification, to support scalability and interoperability of DEVS-based modeling and simulation (M and S) systems. The scalable DEVS specification lists a set of interfaces which create and simulate DEVS models, and control simulation activities among simulators. The distributed container object specification provides a heterogeneous and distributed collection framework focusing on ensemble operations. The proposed specifications contain a rich set of both data and operations which are necessary for building scalable M and S environments that should provide invariance in both performance and quality of service of a system as the size, complexity, and interdependence of its elements increases. We describe design and implementation aspects of those specifications.
