Routing calculates good paths through a network for information to take. For example, from node 1 to node 6 the best routes are likely to be 1-8-7-6, 1-8-10-6 or 1-9-10-6, as these are the shortest routes. Routing is the process of selecting network paths to carry network traffic. Routing is performed for many kinds of networks, including ...
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 Internet protocol suite, as defined in RFC 1122 and RFC 1123, is a high-level networking description used for the Internet and similar networks. It does not define a layer that deals exclusively with hardware-level specifications and interfaces, as this model does not concern itself directly with physical interfaces.
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]
Information technology (IT) is a set of related fields within information and communications technology (ICT), that encompass computer systems, software, programming languages, data and information processing, and storage. [1] Information technology is an application of computer science and computer engineering.
Robert "Bob" Melancton Metcalfe (born April 7, 1946) [2] [3] is an American engineer and entrepreneur who contributed to the development of the internet in the 1970s. He co-invented Ethernet, co-founded 3Com, and formulated Metcalfe's law, which describes the effect of a telecommunications network.
Named Data Networking (NDN) (related to content-centric networking (CCN), content-based networking, data-oriented networking or information-centric networking (ICN)) is a proposed Future Internet architecture that seeks to address problems in contemporary internet architectures like IP. [1] [2] NDN has its roots in an earlier project, Content ...
Jon Postel at work in 1994. Internet science is an interdisciplinary science that examines all aspects of the co-evolution in Internet networks and society. It works in the intersection of and in the gaps among a wide range of disciplines that have had to respond to the impact of the Internet on their 'home turf' and/or offer specific conceptual or methodological contributions.
