Industrial networks

Remote control as well as remote supervising systems are the backbone nowadays producing systems. Both are enabled by different kind of computers and especially microcontrollers connected by different data networks. These networks, industrial networks as their common name is, differ from other data networks in at least in the following: (i) shape of traffic, (ii) available processing capabilities for data interpretation and validation are usually very limited, and (iii) the most important from them is the expected data error renaissance as well as "on time" delivering of correct data. In this article a brief overview of the industrial network issues is given.
