Abstract

The increasing reliance on digital platforms and systems in Cameroon institutions and enterprise necessitates the implementation of highly robust and reliable network systems. The existing network infrastructures, while functional, lack the redundancy and reliability needed to support the growth of digital services.

This project addresses this gap by designing and implementing a mesh network system based on high-level redundancy. The mesh network system leverages an array of network protocols, such as HSRP, EIGRP, Port Channels, NAT, DHCP and some routing protocols to ensure reliable connectivity and data traffic management.

The project also integrates robust security measures, including VLANs, Spanning Tree Protocol, and Root-Bridge, to prevent network loops and ensure secure data traffic.

The network is designed based on the 3-tier hierarchical model, incorporating devices such as edge routers, layer3 switches, routers, switches, end devices, DNS servers, web servers, email servers, and storage servers. The project aims to create a robust, secure, and highly available network that can support the diverse and growing digital needs of businesses and organizations in Cameroon.

Project Motivation

As a network engineer, the motivation stems from the recognition of the vital role that Information and Communication Technology (ICT) plays in the advancement of our society and the unique challenges and opportunities faced in Cameroon.

Cameroon, a lower-middle-income country with a rapidly growing population, is rich in natural resources and cultural diversity but also faces a range of challenges. Economic and social disparities, the aftermath of conflicts, and the pressure of hosting a large number of refugees have placed a strain on the nation’s resources and infrastructure. The global economic turmoil has further increased these pressures, with high inflation and vulnerability to external shocks impacting the daily lives of many Cameroonians.

Despite these challenges, Cameroon has shown resilience and potential for growth. With the help of international partners like the World Bank, projects in various sectors, including transport, energy, telecommunications, and digital transformation, are being implemented to bolster the country’s development and improve the lives of its people.

In the context of these challenges and opportunities, the role of networking and ICT becomes even more crucial. Networking technology is the backbone that supports many of these development initiatives, enabling efficient communication, improving access to information and services, and fostering innovation. Furthermore, the need for robust and reliable networking infrastructure is particularly pressing in terms of accessing information and services.

In light of these circumstances, this project aims to contribute to the efforts to strengthen the networking infrastructure in institutions and enterprises, improve network reliability and access, promote digital inclusion, and support the broader development goals.

CHAPTER ONE

INTRODUCTION

1.1 Background of the Problem

The digital age has brought about a significant shift in the way businesses and organizations operate, with an increasing reliance on digital platforms and systems. Businesses and organizations are rapidly adopting digital technologies to improve their operations and provide better services. However, this digital transformation has put immense pressure on the existing network infrastructures, which were not designed to handle the data traffic and connectivity demands of the digital age.

1.2 Problem Statement

The existing network systems in organizations, institutions and enterprises while functional, lack the redundancy and reliability needed to support the growth of digital services. Network downtimes and disruptions, which are common occurrences with the current infrastructures, can lead to significant losses for businesses and hinder the delivery of critical services. There is an urgent need for a robust and reliable network system that can support the digital transformation in Cameroon.

1.3 Relevance and Justification of the Project

The project is highly relevant as it addresses a critical gap in the current network infrastructures in Cameroon. By designing and implementing a mesh network system based on high-level redundancy, the project aims to improve network reliability and reduce disruptions and network downtime. This would greatly support the digital transformation in Cameroon and help businesses and organizations and institutions better leverage digital technologies.

1.4 Methodology Adopted

The project adopts a systematic approach to designing and implementing the mesh network system. It starts with a thorough understanding of the existing network infrastructures and their limitations. Based on this understanding, the project leverages various network protocols and security measures to design the mesh network system.

The project also uses the 3-tier hierarchical model made up of the core, distribution and the access layer as well as a range of network devices to implement the system. The devices are interconnected using redundant links to help increase the network up time and reduces the risk of network failure.

Furthermore, redundant protocols are also implemented such as HSRP and other efficient networking protocols such as Ether-channel to increase bandwidth.
