Features of Data Center Network Topologies Fit for IIoT Deployments

Industry 4.0 represents a turning point in the manufacturing field due to massive digitalization and the application of artificial intelligence techniques, as it allows to implement a wide range of disruptive actions such as predictive maintenance or smart chain supplies. However, in order to make this all possible, remote computing facilities should be brought to the edge of the network, such as edge/fog computing, which allows communications with low latency and high bandwidth. In this paper, the focus is set on data center network topologies adapted to those environments, characterized by a lower number of end users, thus leading to a lower number of nodes than their cloud computing counterparts. In this context, performance is evaluated using statistical means regarding the average number of links between any pair of nodes.
