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.
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 ...
The textbook definition of a WAN is a computer network spanning regions, countries, or even the world. [3] [4] However, in terms of the application of communication protocols and concepts, it may be best to view WANs as computer networking technologies used to transmit data over long distances, and between different networks.
NetScaler is a line of networking products owned by Cloud Software Group. The products consist of NetScaler, an application delivery controller (ADC), NetScaler AppFirewall, an application firewall, NetScaler Unified Gateway, NetScaler Application Delivery Management (ADM), and NetScaler SD-WAN, which provides software-defined wide-area networking management.
A secure access service edge (SASE) (also secure access secure edge) is technology used to deliver wide area network (WAN) and security controls as a cloud computing service directly to the source of connection (user, device, Internet of things (IoT) device, or edge computing location) rather than a data center.

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 many other ...
MEF, founded in 2001, is a nonprofit international industry consortium, of network, cloud, and technology providers. [1] MEF, originally known as the Metro Ethernet Forum, was dedicated to Carrier Ethernet networks and services, and in recent years, significantly broadened its scope, which now includes underlay connectivity services such as Optical, Carrier Ethernet, IP, along with overlay ...
