What is Network architecture?
Network architecture is the design of a communications network. It includes the physical and logical layout of the network, the framework of accepted standards and specifications of elements, equipment, services, protocols and functions, growth and change assumptions, and high-level operational principles and procedures.
Modern networks encompass a variety of architectural and design principles, which must be understood and articulated by a network organization in order to maintain best practices.
The network architecture provides a framework for organizing the functional Requirements needed for the global network. The elements must be modular (that is, specified independently of each other) so that different implementations can realize those elements in ways that encourage the use and development of technological innovations. The modularity of the Internet and OSI architectures has permitted the immediate incorporation into networks of higher-speed computers, links, and switches.
On the other side, network architecture is the infrastructure consisting of software, transmission equipment, and communication protocols define the structural and logical layout of a computer network. The mode of transmission of a network can be wired or wireless depending on the requirements in an organization. There are various types of networks that can be applied in an organization depending on the network size. Local area network (LAN) refers to network in a small geographical area, Metropolitan area network (MAN) refers to network in a city, and wide area network (WAN) refers to network that is spread geographically in a wide area. Among the three types of network, the company would implement LAN since it is only covering a small geographical area.
