A WAN is not only the physical line. It is also made up of networking hardware, software, and other technologies. An example of a networking technology is MPLS which helped make WANs faster and less expensive. MPLS uses short router adresses in a VPN, designed to get from one network site to another, thereby lessening the call on router databases. A SD-WAN (Software Driven WAN) is a culmination of technologies that replace expensive routers and make the network development and expansion much faster and cheaper. WAN providers in West Jefferson have significantly less expensive service thanks to Software-defined Wide Area Networks.
