Software-defined wide-area network (SD-WAN) is a very effective add-on to the classic WAN. In the conditions of complex topology and multiple physical communication channels within a distributed computing network, which can include sections with MPLS, 4G LTE and even xDSL, software traffic management turns bulgaria mobile database to be an indispensable alternative to manual administration of routing tables. The next step in revealing the potential of SD-WAN - autonomous networking - has become available to customers very recently, as elements of information security are introduced into the network management structure, and artificial intelligence takes over control over it.

Simpler means better
The basic concept of software-defined networking (SDN) is to separate network equipment management from data transmission management. The traditional network design relies on highly specialized routers and switches, which are expensive for the customer (since they are expensive to develop and their production volumes are relatively small), and also require special knowledge and serious qualifications from the service personnel.

The software for organizing SDN can run on any serial computer, easily ensures the transition from manual management of individual network equipment to network management as a whole, and also forms a software-controlled interface between the network application and the network transport environment. In some cases, it is permissible to use classic switches and routers with software overlays that allow the control software to abstract the data flow from the architectural features of a particular proprietary hardware. SDN consists of three basic planes: data, control, and applications, with the control plane logically centralized and separated from the data plane.
