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 ...
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.
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.
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).
