A codesign approach for distributed systems

摘要

Distributed systems have become prevalent in response to the rapidly expanding Internet's demands. Their design presents new challenges because it involves the interaction of hardware and software. Continual marketplace innovation drives computing toward heterogeneity in both hardware and software and generates a complexity that goes beyond the earlier codesign approaches, which were developed for more homogeneous systems executing in non-distributed environments. Codesign of heterogeneous systems requires the support of a powerful modeling and simulation environment because analysis alone cannot deal with all the challenges such complex systems pose. We believe that modeling and simulation, using the discrete-event system specification modeling and simulation framework, are the most suitable vehicles to study the complexities associated with developing distributed-object computing systems.
