A System for Experimental Research in Distributed Survivability Architectures1

چکیده
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 architectures. Experimental systems research in this area is complicated by the private ownership, criticality, and complexity of infrastructure systems. A key research method is therefore to explore and evaluate novel architectural concepts by prototyping them within simulations of infrastructure systems. We present a toolkit to support the construction of such simulations 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 simulations 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 evaluated several novel architectures, including one based on distributed hierarchical control.

Development of an Ensemble Multi-stage Machine for Prediction of Breast Cancer Survivability
Prediction of cancer survivability using machine learning techniques has become a popular approach in recent years. In this regard, an important issue is that preparation of some features may need conducting difficult and costly experiments while these features have less significant impacts on the final decision and can be ignored from the feature set. Therefore, developing a machine for p...

متن کاملSecurity and Survivability of Distributed Systems: an Overview
Society is growing increasingly dependent upon large-scale, highly distributed systems that operate in unbounded network environments, which like the Internet, have no central administrative control and no uni$ed security policy. Despite the best efforts of security practitioners, no amount of system hardening can assure that a system that is connected to an unbounded network will be invulnerab...
