Heretofore, most network equipment had to be configured individually by connecting manually into it. This approach is time consuming for large networks and prone to human errors. The Software Defined Networking paradigm defines several standards and protocols in order to read the network states and act on its configuration from distant servers. These protocols authorize a reconfiguration of the network in a centralized way by the use of transactions that acts on one or more devices. In general, transactions are implemented as APIs for use by third- party programs and on software components separate from the orchestrator called controllers for more modularity. Nowadays, SDN receives a lot of interest from researchers and manufacturers aiming for the modernization of the networks especially with the emergence of the loT, 5G and WAN technologies.
