Goals

Since several years, already, distribution became de facto architectural choice in many application domains, from process control to factory automation and even embedded systems, bringing the role of the underlying networks to the foreground. In these systems, communications support the internal interactions that lead to the desired global behavior and they have a particular impact on the non-functional properties, such as timing and fault-tolerance. This course will present an introduction to computer networks that are typical in embedded systems from a real-time perspective. The lectures include an initial presentation of general concepts in networks and then focus on the physical and data link layers, devoting particular attention to the medium access control. Then, the course will address the issue of traffic scheduling and its relationship with medium access control, showing typical schedulability analysis that can be used to derive a priori guarantees of traffic timeliness. A few paradigmatic protocols will then be presented and analyzed, including a reference to the growing interest on wireless communication. Finally, the course will address the holistic design of a distributed embedded system, considering tasks and messages and presenting a specific case study.
