WAN Engineers (Wide Area Network) are the Telecom/IT professionals that set up and maintain wide area networks for businesses that need these networks to operate regularly. Besides designing WAN networks, they spend much time analyzing, testing and evaluating networks to make sure that they run properly and that they have the resources necessary for smooth functioning.

WAN engineers use their expertise in IT to interconnect network systems. They check WAN performance, capacity, security settings, and approvals. Typically, a WAN has at least two LAN’s and covers big geographical areas. Network flow maintenance is important for WAN engineers. WAN’s future is Software-Defined. The SD-WAN is a specific application of SDN technology applied to WAN applications. An SDN offers cloud-enabled WAN connections.
