Computer Dynamics Network Design and Implementation Report

This report assesses Computer Dynamics' existing network infrastructure, which suffers from congestion, lack of physical connection between two buildings, and inefficient VPN setup. It analyzes user requirements across various departments, estimates capacity, and proposes a new network design featuring a fiber optic cable connection between buildings and layer 3 switching for improved data transfer. The report includes a cost estimation and recommendations for enhancing network performance and disaster recovery. The goal is to provide a scalable network solution that meets the company's current and future needs, ensuring efficient data communication and supporting business growth. Desklib provides access to this and other solved assignments for students.

Executive Summary
Computer Dynamics currently uses a network that does not have a physical connection between
the two buildings that the company uses and the network is also overloaded, this creates the basis
of the report which includes assessing the existing network infrastructure, where the
management and the users of the network being interviewed and offer the solution that is recent
enough and can overcome this critical problem hence meeting the company’s needs.
It was found that, the existing network is overloaded and congested, slow and therefore cannot
support the growth of the business with relation to increased number of projects that are being
created . Physical connection between the two buildings occupied by the organization is not their
hence the two are sharing information across VPN site to site tunnel which is not efficient.
It was therefore recommended that a physical connection is required to connect between the two
buildings; this can use fiber optic cable for connection. Three layer switching is applied to this
because enhances high speed in data transfer between the components in the network. The usage
of fiber optic cable between buildings enhances high data communications between the
buildings and transfer of information.

1.0 INTRODUCTION
1.1 PURPOSE
The core purpose of this report is to evaluate the nature of the network infrastructure that
existed before at Computer Dynamics in relation to the objectives of the organization and put
down necessary strategies to improve the network infrastructure in order to achieve the
maximum functioning of the system.
1.2Background
Computer Dynamics is a well based software company . the company has a network that existed
before and the network is currently housing three hundred computers in two different buildings.
Though the network was upgraded to a latter network infrastructure, the company as now grown
because of good marketing of the company.
In the previous network, there was no network connection between the two buildings, also the
current network has problems due to high rates of overloading of data caused by a higher
number of users and many other reasons of overloading. In any case this network is not upgraded
to a better and latest network technologies, the problem might persist because more projects are
expected in the coming days.
From the problems that the association phases it has decided to change the layout of the
network structure. Cisco has been given the task to investigate and come up with a network
layout that will be used to upgrade the network structure in the company.

1.3 Scope of the report
In generally the structure of the network in the company is mentioned in relation to the goal of
the business for the network. In addition, an analysis regarding the user requirements and the
network that is currently existing in the organization is critically performed . the main areas that
are covered in this report includes according to Agata(2012):
i. The requirement of the user and capacity level.
ii. The existing network infrastructure that includes diagrams.
iii. The hardware
iv. The software that is being utilized including the client, network, operating system and
importantly the server.
v. The whole network layout, they are logical and physical network topologies.
vi. The performance of the existing network.
The layout of the proposed network is stated within the report and is aimed at serving the
company for 3-5 years maintaining its high capacity. Circuitry includes connection of
infrastructure, Hardware/Devices , Software ,Network Architecture.
2.0ANALYSIS OF USER REQUIREMENTS Laner( 2010)
