3.1 Overview of Software‐Defined Networking

Software‐defined networking (SDN) emerges as one of the noteworthy networking concepts which gives the hope to modify the limitations of current network infrastructures [1]. SDN has transposed the way of managing the network, and it is defined by two different tendencies: (i) SDN decouples the control level (controllers) from the data level (forwarding plane), and (ii) decoupling makes the control level programmable by the end users. In conventional networks, it is hardly possible to separate the control level from the data level [2]. Therefore, the end users had to be dependent on the merchants for the configuration of a software network and its users. This traditional network data plane informs your data where it is required to go, and the control plane is situated inside a switch or router, which could make the decision of progressing the packet and is also in charge of maintaining the routing table information and required to reserve the data; SDN was defined to design, build, and manage the networks that decouple the network layer and forwarding layer and is directly programmable ...
