High Level Network Design

A LAN HLD (high level design) is a type of architecture used in local area networks, which is designed to help streamline operations in a variety of different computer networks. It details how different hardware and software components within the network should interact with each other, while also outlining the overall design principles behind the network. It outlines the exact building blocks required to put together a functional local area network, such as switches, routers, firewalls, cabling, etc. It also explains how network access is administered, in order to ensure that only authorized users can gain access to the network. Lastly, a LAN HLD outlines the various protocols and technologies needed for inter-connectivity between different network elements.
