SD WAN and Hybrid WAN

Concepts and Solutions

ExperTeach Networking Logo

Network architectures are subject to a complete renewal, which was initiated by the advent of Software-Defined Networking (SDN). In addition to the creation of new options, such as the reconstruction of data paths in seconds due to full automation, particularly the operation of an enterprise network is to be pushed here in the direction of a higher efficiency and flexibility. This trend already affects the design concepts of WAN connections. In addition to the very reliable MPLS-VPNs, cost-effective Internet accesses are available as WAN connections. In order to use both optimally in terms of the QoS demands of the applications, the Hybrid WAN concept was developed as an interim step in the direction of the Software-Defined WAN. Here, the data traffic is controlled by means of controller functions distributed in the network, while central control plane servers are used for this purpose in the SD-WAN.
