The Center for Resilient Networks and Applications

The research in Communication Systems at Simula Research Laboratory is done through the Center for Resilient Networks and Applications.  The center is a response to modern society’s massive and increasing dependability on applications running on top of the Internet, as well as to recent events where outages have had serious societal consequences.

CRNA works on the robustness and security of ICT infrastructures, by which we mean that applications should continue to function at the best possible level of quality and security, even in the presence of technical failures, unplanned excessive load, design and implementation flaws in specific components, human error and malicious intent.

The Center receives base funding from the Norwegian Ministry of Transport and Communications.  The Ministry has given the Center specific responsibilities through a mandate that includes publishing an annual report on the state of the Norwegian telecommunications infrastructure.

CRNA has its organizational home at Simula, and consists of the research area Communication Systems in Oslo, Simula@UiB in Bergen, as well as the ConSeRNS initiative at the University of Oslo.

The Center consists of the following units

Communication Systems

The projects under the research area of Communication Systems at Simula are engaged in the research and development of  resilient 

 The Networks department works on resilience in communication networks both from a measurement angle, through prototyping and through theoretical studies. A special responsibility for parts of the mandate of CRNA lies with this department.  This includes maintaining an infrastructure for measurements and experimentation on the Norwegian commercial network infrastructure, and publishing an annual report on the measured state of these networks.

The Media department addresses resilience in the context of resource utilization and performance challenges to support a wide range of interactive multimedia services to the large user masses of the Internet. The goals are to reduce the costs, increase the number of users and optimize the perceived service quality.

This department is addressing the efficiency and robustness of large computer installations, ranging from enterprise systems to supercomputers and cloud installations. As an increasing number of networked applications have dependencies that extend into such installations, cloud facilities must eventually be considered part of a society’s critical ICT infrastructure.


This part of the center works on preventing and mitigating the effects of hostile and targeted attacks. The expertise of this department includes cryptography, information theory, and computer security.  The Security team is part of the Selmer Center at the Department of Informatics, University of Bergen, and it is co-funded by Simula and the University of Bergen.

From the University of Oslo:


ConSeRNS is an initiative at the University of Oslo whose mission is to bootstrap a strong activity on robustness and security. The initiative is run by 12 faculty members from UiO, and combines expertise in networking, distributed systems, formal analysis, cryptography and computer security.


Mandate for CRNA

The Center will undertake long-term research and innovation at a high international level, on robustness and reliability of communications networks and applications. The Center will educate experts on the doctoral and magisterial levels in cooperation with universities and university colleges. 

Furthermore, the Center will have responsibility for maintaining and running a research infrastructure for measuring the Norwegian telecommunications network. This research infrastructure will be made available for research groups at universities and university colleges. The Center wishes to provide measurement and monitoring services for regions, municipalities, industry and public enterprises in Norway. The Center will produce an annual report on the state of the Norwegian communications infrastructure to the Norwegian Post and Telecommunications Authority.

The Center's ambition will be to be the nationally leading research institution within research on reliable ICT infrastructures, and collaborate with other research institutions that have expertise that will not be naturally covered by the Center. It will be expected that the Center collects additional funding from sources such as the Norwegian Research Council. EU research programmes, industry and relevant parts of the public administration. 

The Center is part of Simula Research Laboratory's organisational structure. CRNA will perform annual management and dialogue meetings with the Norwegian Ministry of Transport and Communication and the Norwegian Post and Telecommuncations Authority. The work performed at the Center will be evaluated by the Research Council every five years. The criteria for evaluation will be related to scientific quality and relevance to society. The annual budgets for the Center are dependent on grants from the state budget and will be considered on the background of the evaluation results.
