Local area network segmentation model

Abstract

This paper conveys the basic aspects of designing and segmenting the local area network of a multisectoral enterprise. The main focus of the paper is centered around the practical work of creating and configuring independent virtual network segments within one physically connected computer network using the 'Cisco IOS' command line interface. Practical steps of network configuration were simulated and represented by the virtualization software simulating the real world surrounding and interactions made between the network components. The structure of the protocols that shape the segmentation of a computer network to virtual local computer networks is presented as the most efficient segmentation method. The benefits of segmentation of the local computer network are explained. Special focus is given to the use of the Cisco IOS command language syntax as the most common programming language among network devices.
