The term What is SD-WAN
is an acronym that stands for Software-Defined Wide-Area Network. It is a term that relates to SDN
(Software-Defined Networking) and is something that is used by thousands of companies across the country and further afield as they look to connect different parts of their business to a wireless network.
This is achieved via the application of SDN technologies to WAN connections. Examples of WAN connections include broadband connections, 4G, and LTE. The function is to connect the various business premises to the same, secure network through the internet or a cloud-native private network.
The use of the SD-WAN system is, therefore, an upgrade from outdated computer network
frameworks of the past as they are detached from traffic management and hardware-based monitoring functions. Instead, it is built upon; Edge Connectivity Abstraction, WAN Virtualization, Centralized Management, and Elastic Traffic Management.
A software-defined wide area network can be used in favour of T1, MPLS
, and other traditional WAN systems, although over three in four companies still persist with the old facilities in conjunction with their SD-WAN networks.
