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]
An SD-WAN is a WAN managed using the principles of software-defined networking. [51] 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 port numbers in the range from 0 to 1023 (0 to 2 10 − 1) are the well-known ports or system ports. [3] They are used by system processes that provide widely used types of network services. On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the ...
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.
SD-WAN is a technology that simplifies wide area networking through centralized control of the networking hardware or software that directs traffic across the WAN. It also allows organizations to combine or replace private WAN connections with Internet broadband , LTE and/or 5g connections.
The company was founded in 2004 by David Hughes. Silver Peak shipped its first product, the NX-series hardware appliance, in September 2005, and their first SD-WAN solution, EdgeConnect, in June 2015. On July 13, 2020, Hewlett Packard Enterprise announced its intent to acquire Silver Peak for $925 Million.
They are more specialized than general drawing tools and provide network engineers and IT systems administrators a higher level of automation and the ability to develop more detailed network topologies and diagrams. Typical capabilities include but not limited to: Displaying port / interface information on connections between devices on the maps
