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. [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 ...
In addition, when the scope of a diagram crosses the common LAN/MAN/WAN boundaries, representative hypothetical devices may be depicted instead of showing all actually existing nodes. For example, if a network appliance is intended to be connected through the Internet to many end-user mobile devices, only a single such device may be depicted ...
Technical Report 069 (TR-069) is a document by the Broadband Forum that specifies the CPE WAN Management Protocol (CWMP). CWMP is a SOAP -based protocol for communication between an internet service provider auto configuration server (ACS) and customer-premises equipment (CPE).
X.25 is an ITU-T standard protocol suite for packet-switched data communication in wide area networks (WAN). It was originally defined by the International Telegraph and Telephone Consultative Committee (CCITT, now ITU-T) in a series of drafts and finalized in a publication known as The Orange Book in 1976.
Examples include personal VPN, site-to-site VPN, private networks such as MPLS and SD-WAN, or via private SBCs (Session Border Controllers). While exceptions and private peering options do exist, it is generally uncommon for those private connectivity methods to be provided by Hosted or Cloud VoIP providers.
Though network documentation can be done by hand, large organizations must use network documentation software, including diagramming tools, inventory management, and circuit and cable traces. Examples include draw.io, Graphical Networks' netTerrain, [4] Microsoft Visio, [5] Docusnap, Gliffy, [6] Opnet's Netmapper, and XIA Configuration. [7]
A storage area network (SAN) or storage network is a computer network which provides access to consolidated, block-level data storage.SANs are primarily used to access data storage devices, such as disk arrays and tape libraries from servers so that the devices appear to the operating system as direct-attached storage.
