A Survey of Research into Mixed Criticality Systems

Alan Burns, Robert I. Davis
2017 ACM Computing Surveys  
Systems with more than one criticality level that only aim to give complete isolation are called multiple-criticality systems; the use of mixed-criticality implies some tradeoff between isolation and integration  ...  The criticality of a component determines the level of rigour applied in the design and analysis used to determine its correct functionality and resource usage (e.g. processor execution time, communication  ...  Acknowledgements The authors would like to thank Sanjoy Baruah for a number of very useful discussions on MCS.  ...

2011 Proceedings of the Seventh COnference on emerging Networking EXperiments and Technologies on - CoNEXT '11  
In this paper, we propose REsPoNse, a framework which overcomes the optimalityscalability trade-off.  ...  The insight in REsPoNse is to identify a few energy-critical paths off-line, install them into network elements, and use a simple online element to redirect the traffic in a way that enables large parts  ...  Our sensitivity analysis shows that excluding 20% of the links with the highest stress is sufficient to produce a set of paths that together with the always-on paths can accommodate peak-hour traffic demands  ...

Modelling Security of Critical Infrastructures: A Survivability Assessment

Ricardo J. Rodríguez, José Merseguer, Simona Bernardi
2014 Computer journal  
In this paper, we present a UML profile, named SecAM, that enables the modelling and security specification for critical infrastructures during the early phases (requirements, design) of systems development  ...  The stochastic analysis, carried out with Generalized Stochastic Petri nets, quantitatively estimates the minimisation of attack damages into the crude-oil network.  ...  Although the paper illustrates qualitative analysis and vulnerability analysis, the Petri net also allows to compute resource optimisation of the critical infrastructure, and to provide feedback to the  ...

Schedulability of probabilistic mixed-criticality systems

Stefan Draskovic, Rehan Ahmed, Pengcheng Huang, Lothar Thiele
2021 Real-time systems  
When this is done, the usual assumption is that tasks of lower criticality are degraded when a higher criticality task needs more resources, for example when it overruns a bound on its execution time.  ...  AbstractMixed-criticality systems often need to fulfill safety standards that dictate different requirements for each criticality level, for example given in the 'probability of failure per hour' format  ...  Appendix: Computational complexity of the analysis Here we comment on the computational complexity of our proposed probabilistic Mixed Criticality (pMC) schedulability analysis.  ...

Software Composability and Mixed Criticality for Triple Modular Redundant Architectures

Stefan Resch, Andreas Steininger, Christoph Scherrer
2013 International Conference on Computer Safety, Reliability, and Security  
Composability and mixed criticality are concepts that promise an ease of development and certification for safety critical systems in all industrial domains.  ...  We evaluate the needed adaptations and extensions of triplication mechanisms with respect to the required safety properties.  ...  However, composability and mixed-criticality can achieve good resource utilization, as non-critical FSs are not replicated.  ...
