Per MEF 70, the SD-WAN Edge classifies incoming IP packets at the SD-WAN UNI (SD-WAN user network interface), [14] determines, via OSI Layer 2 through Layer 7 classification, which application flow the IP packets belong to, and then applies the policies to block the application flow or allow the application flows to be forwarded based on the ...
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 ...
There are several types of Cisco Interface Card. Cisco introduced the High Speed WIC, or "HWIC" with the x800 series of Cisco Integrated Service Router including the 1800, 2800, and 3800 series'. The HWIC interface is limited to 400 mega-bits per second bandwidth bidirectional. [2] With the ISR G2 x900 series Cisco introduced the Enhanced HWIC.
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.
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).
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]
WAN optimization is a collection of techniques for improving data transfer across wide area networks (WANs). In 2008, the WAN optimization market was estimated to be $1 billion, [1] and was to grow to $4.4 billion by 2014 according to Gartner, [2] a technology research firm. In 2015 Gartner estimated the WAN optimization market to be a $1.1 ...
