- Software-defined networking, or SDN, is revolutionizing our network architectures. At its most basic level, software-defined networking allows us to use software to replace traditional network devices. Still, it's a little bit more complicated than that, so we're going to spend some time in this lesson discussing it. To better understand software-defined networking, we must first understand the three portions of a typical network architecture, the control plane, the data plane, and the management plane. Now, the control plane is responsible for carrying the traffic that provides the signals to and from a router, such as those used in sharing information and building routing tables. The control plane makes decisions about how traffic should be prioritized and secured and where it should be switched to in the network. So, if you think about a router or a switch or a QOS device like quality of service devices, these all operate at the control plane layer. Now, the data plane is going…
