Software-defined networking ( SDN) is an approach to network management that enables dynamic and programmatically efficient network configuration to improve network performance and monitoring in a manner more akin to cloud computing than to traditional network management. [ 1] SDN is meant to improve the static architecture of traditional ...
OpenFlow allows direct access to and manipulation of the forwarding plane of network devices such as switches and routers, both physical and virtual (hypervisor-based). It is the absence of an open interface to the forwarding plane that has led to the characterization of today's networking devices as monolithic, closed, and mainframe-like.
OpenDaylight. The OpenDaylight Project is a collaborative open-source project hosted by the Linux Foundation. The project serves as a platform for software-defined networking (SDN) for customizing, automating and monitoring computer networks of any size and scale.
Network functions virtualization (NFV) [ 1] is a network architecture concept that leverages IT virtualization technologies to virtualize entire classes of network node functions into building blocks that may connect, or chain together, to create and deliver communication services. NFV relies upon traditional server- virtualization techniques ...
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 ...
Software-defined networking (SDN) is a marketing term which refers to software to configure and operate computer networks (especially data center networks) through a centralized software controller that dictates how the network behaves. [1] The core of this new paradigm is the SDN controller. There are typically two sets of SDN controllers:
The Open Networking Foundation ( ONF) is a non-profit operator -led consortium. [ 1] It uses an open source business model aimed at promoting networking through software-defined networking (SDN) and standardizing the OpenFlow protocol and related technologies. [ 2] The standards-setting and SDN-promotion group was formed out of recognition that ...
Application Fluent Network is an addition of SDN capabilities. The acronym 'AFN' is used by Alcatel-Lucent Enterprise to refer to an Application Fluent Network. Application delivery uses one or more layer 4–7 switches , also known as a web switch, content switch, or multilayer switch to intelligently distribute traffic to a pool, also known ...
