Abstract
The survivability of critical infrastructures is not assured today because of their reliance on complex, vulnerable information systems. Survivability enhancement will require changes to system archi- textures. Experimental systems research in this area is complicated by the private ownership, criticality, and complexity of infrastructures systems. A key research method is therefore to explore and evaluate novel architectural concepts by prototyping them within dynamic models of infrastructure systems. We present a toolkit to support the construction of such models and the prototype-based evaluation of novel architectural idioms. The toolkit captures common features of infrastructure systems that challenge the state of the art in survivability management. Our models and prototype constructs run on workstations running Windows 2000 and function as distributed systems of programmable, message-passing processes with reflective capabilities. We have built infrastructure models with up to 20,000 processing nodes,and we have evalu- ated several novel architectures, including one based on distributed hierarchical control.
