GEMOM Middleware Self-healing and Fault-tolerance: a Highway Tolling Case Study

Application of message-oriented communication in business critical systems has to cope with requirements for end-to-end intelligence, security, scalability, self-adaptation and fault-tolerance. To this extent, the Genetic Message-Oriented Middleware (GEMOM) European Research Project focused on the design and development of a fast-forwarding message oriented middleware, endowed with robustness, resilience, self-adaptability, and scalability capabilities. This paper reports on the design, development and testing results of a case study for the GEMOM middleware on highway toll data management and collection. The case study has a twofold objective: first, it offers a reference scenario that poses requirements challenging a specific set of self-healing and fault-tolerance GEMOM features and thus providing an application scenario suitable for features validation; second, it aims at representing a real-world application scenario and consequently at providing valuable insights on GEMOM exploitability in a specific market sector.
