Network design refers to the planning to implement a computer network infrastructure. Network design is generally performed by network designers, network engineers, IT administrators and other related staff. It is done before the implementation of a network infrastructure.
Network design has three main steps
Topological design, determining where to place and connect the components.
Network-synthesis, determining the size of the components to be used.
Network realisation, determining how to meet capacity requirements and ensure reliability within the network.
A comprehensive and well thought out network design is essential for your business to perform its core functions and ability to sustain business growth.
