Software network functions (NFs), such as a network address translator, load balancer, or proxy,
promise to bring flexibility and rapid innovation to computer networks and to reduce operational costs.
However, continuous updates and flexibility typically c ...
Verification is a costly task, sometimes burdensome and tedious, requiring strong formal background. To reduce the effort and cost invested in verification, we developed a model-driven approach for automatic verification of service properties, done in the ...
Systems should not only be correct but also robust in the sense that they behave reasonably in unexpected situations. This article addresses synthesis of robust reactive systems from temporal specifications. Existing methods allow arbitrary behavior if ass ...
The basic idea behind the provision of a service is to hide the service implementation details from the client in such a way that more value is provided to the client. Very often support services allow too much of their implementation details to be visible ...
The formal specification component of verification can be exported to simulation through the idea of property checkers. The essence of this approach is the automatic construction of an observer from the specification in the form of a program that can be in ...
Model-Driven Engineering (MDE) harbors the promise of developing software-based systems with little or no coding. Instead of coding, it is envisioned that software engineers build models that are automatically translated into code. The modeling notation of ...
In this dissertation we investigate how Business/IT alignment in enterprise models can be enhanced by using a software engineering stepwise refinement paradigm. To have an IT system that supports an enterprise and meets the enterprise business needs, manag ...
Turing Lecture from the winners of the 2007 ACM A.M. Turing Award.In 1981, Edmund M. Clarke and E. Allen Emerson, working in the USA, and Joseph Sifakis working independently in France, authored seminal papers that founded what has become the highly succes ...
IT organizations that wish to implement the best practices recommended by the IT Infrastructure Library (ITIL) need to specify the level of service provided to their customers. The implemented service needs to comply with this specification. We propose a m ...
Creation and transformation of visual specifications is driven by modeler’s design decisions. After a design decision has been made, the modeler needs to adjust the specification to maintain its correctness. The number of adjustments might make the design ...
