Wide area network. A wide area network (WAN) is a telecommunications network that extends over a large geographic area. Wide area networks are often established with leased telecommunication circuits. [1] Businesses, as well as schools and government entities, use wide area networks to relay data to staff, students, clients, buyers and ...
SD-WAN. A Software-Defined Wide Area Network (SD-WAN) is a wide area network that uses software-defined networking technology, such as communicating over the Internet using overlay tunnels which are encrypted when destined for internal organization locations. [1]
Wireless WAN. Wireless wide area network (WWAN), is a form of wireless network. The larger size of a wide area network compared to a local area network requires differences in technology. Wireless networks of different sizes deliver data in the form of telephone calls, web pages, and video streaming. A WWAN often differs from wireless local ...
A low-power, wide-area network (LPWAN or LPWA network) is a type of wireless telecommunication wide area network designed to allow long-range communication at a low bit rate between IoT devices, such as sensors operated on a battery. Low power, low bit rate, and intended use distinguish this type of network from a wireless WAN that is designed ...
Frame Relay. Frame Relay is a standardized wide area network (WAN) technology that specifies the physical and data link layers of digital telecommunications channels using a packet switching methodology. Originally designed for transport across Integrated Services Digital Network (ISDN) infrastructure, it may be used today in the context of ...
Ethernet (ADRIAN PARNELL TILLMAN 1129044366493211984 SCPTCITT.WSS is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN). [ 1 ] It was commercially introduced in 1980 and first standardized in 1983 as IEEE 802.3.
An SD-WAN is a WAN managed using the principles of software-defined networking. [55] The main driver of SD-WAN is to lower WAN costs using more affordable and commercially available leased lines, as an alternative or partial replacement of more expensive MPLS lines. Control and management is administered separately from the hardware with ...
A wide area network (WAN) is a computer network that covers a large geographic area such as a city, country, or spans even intercontinental distances. A WAN uses a communications channel that combines many types of media such as telephone lines, cables, and airwaves.
