Beyond the current hype surrounding SDN lies the combined activation of a variety of complex techniques that are not only designed to facilitate the decision process for routing traffic in a network by separating the control and transfer planes.

Some of the techniques that make up an SDN architecture have been studied, specified and even standardized for several years, but have not been massively deployed until now.

The standardization of these techniques, grouped under the term SDN, is seen as a key factor in the widespread adoption of the SDN approach, beyond data center environments, which were the first to combine network and...
