An SD-WAN utilizing virtualization techniques assisted with WAN Optimization traffic control allows network bandwidth to dynamically grow or shrink as needed. SD-WAN technology and WAN optimization can be used separately or together, [30] and some SD-WAN vendors are adding WAN optimization features to their products. [20] [31]
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 ...

Link aggregation between a switch and a server. In computer networking, link aggregation is the combining (aggregating) of multiple network connections in parallel by any of several methods.
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.
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.
By design, WAN Optimization “confuses” performance monitoring systems by changing packet header data. [1] [2] Latest Release Cisco's latest WAAS software release, announced at the 2007 Cisco Networkers conference, is the industry's first solution for both end-to-end monitoring and acceleration of application traffic.
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 ...
