The purpose of RTNS is to provide a venue for sharing new ideas, experiences and information among academic researchers, developers and service providers in the field of real-time systems and networks. The 24th edition of the conference continued the established series with a rich program of 34 papers (out of 75 submissions), with a diversity of topics, such as transactions and distributed systems, network analysis, synchronous dataflow graphs, scheduling and schedulability, periodic systems and control, network optimization, many-core and networks-on-chip, multicore scheduling, timing analysis, parallelism, a clear demonstration of the broad scope of real-time systems and networks research. The special issue consists of four papers that cover various areas, from high level system design and optimization to low level timing analysis of computer systems and networks, which have undergone a rigorous peer-review process according to the journal’s high standards. The first paper “A Design Flow for Supporting Component-based Software Development in Multiprocessor Real-Time Systems”, written by Alessandro Biondi, Giorgio Buttazzo and Marko Bertogna, presents a design flow for component-based development on multiprocessor platforms, using Mixed-Integer Linear Program (MILP) formulations. The proposed methodology first addresses the problem of partitioning applications into virtual processors using reservation servers, and then a second method to allocate virtual processors to physical processors, both taking resource sharing into account. The methodology is evaluated both in terms of schedulability as well as run-time of the optimization problem. The second article “Optimal Harmonic Period Assignment: Complexity Results and Approximation Algorithms”, written by Morteza Mohaqeqi, Mitra Nasri, Yang Xu, Anton Cervin, and Karl-Erik Årzén, is about the design of digital control systems, where the period of tasks can be chosen within a certain range without impairing the B Sébastien Faucou Sebastien.Faucou@univ-nantes.fr 1 Université de Nantes, LS2N, UMR 6004 CNRS, Nantes, France 2 Polytechnic Institute of Porto, Porto, Portugal
