Network architecture is the design of a computer network.It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as communication protocols used.
A high-level overview of the software-defined networking architecture. The following list defines and explains the SDN architectural components: [32] SDN application SDN applications are programs that communicate their network requirements and desired network behavior to the SDN controller via a northbound interface (NBI). In addition, they may ...
Systems Network Architecture [1] (SNA) is IBM's proprietary networking architecture, created in 1974. [2] It is a complete protocol stack for interconnecting computers and their resources. SNA describes formats and protocols but, in itself, is not a piece of software.
Delay-tolerant networking (DTN) is an approach to computer network architecture that seeks to address the technical issues in heterogeneous networks that may lack continuous network connectivity. Examples of such networks are those operating in mobile or extreme terrestrial environments, or planned networks in space.
Core network components interconnect other network components. Gateway: an interface providing a compatibility between networks by converting transmission speeds, protocols, codes, or security measures. [9] Router: a networking device that forwards data packets between computer networks.
An internetwork is the connection of multiple different types of computer networks to form a single computer network using higher-layer network protocols and connecting them together using routers. The Internet is the largest example of internetwork. It is a global system of interconnected governmental, academic, corporate, public, and private ...
Active networking is a communication pattern that allows packets flowing through a telecommunications network to dynamically modify the operation of the network.. Active network architecture is composed of execution environments (similar to a unix shell that can execute active packets), a node operating system capable of supporting one or more execution environments.
