Advanced Digital Computers Company Information System Network Report

This report offers a comprehensive overview of the network design for Advanced Digital Computers Company (ADCC). It details the company's network requirements, including bandwidth and uptime specifications. The report outlines the assumptions made in the network design process, such as the number of subnets and the allocation of IP addresses. It specifies the network connection media, including copper and fiber optic cables, along with their respective costs and justifications. A key aspect of the report is the detailed explanation of the ADCC network addressing schemes, encompassing both IPv4 and IPv6, along with the calculation of IP addresses for each branch. The selection of network hardware, including routers and switches, is justified based on the network's needs. The report further describes the network topologies for each branch, including head office, Chatswood, Leichhart, Rockdale, Bankstown, Epping, and the server network, with diagrams illustrating the network layout. Finally, it proposes fiber optic cable internet access and concludes with a summary of the findings.

1 Executive summary
Advanced Digital Computer Company is located in Australia that sells the computer items to
their customers and they have many branches across the country. However in this report the
various branches subnets are identified, assigned IP addresses and also their network topologies
are drawn for easy implementation and configuration process.
Keywords: Switches, Routers, Servers, IPv4 IP address, IPV6 IP address, Topology.
2 Introduction
Advanced Digital Computer Company is a computing company that mainly deals with the
selling of the various computing devices to the residents of Australia country and beyond, it has
various branches and they are distributed in many towns’ centers.
The company is allocated IP address by their internet service providers which includes the ipv4
and ipv6 as 172.16.0.0/20 and 2001: acad:: bead:/60 respectively where an IP address scheme
will be used to allocate the various subnets to certain IP addresses depending with number of
hosts and this will allow growth since the network is expected to undergo 100% growth resulting
to doubling of the network devices.
2.1 The made assumptions
Below are some of the assumptions made in the network designing to enable the accommodation
of all network devices including the one that will added after the network undergo 100% growth.
i. The network will have a total of six subnets which will be interlinked.
ii. Each branch will be assigned its unique IP addresses and range depending with the
number of hosts.
iii. There will be six subnets for the all six network branch locations.
iv. There will be one or many printers in each subnet in a ratio of 1 printer: 70
computers.
v. Each network will be having the switch and router hardware depending on the
number of the end devices in a subnet or branch.

Advanced Digital Computers Company Information System Network Essentials 4
vi. For each member of the company there will be only one dedicated computer.
vii. The network devices and end devices connection will be established using the cables
like the cat 5, 6 and 7.
viii. The subnets to the head office connection media will be fiber cables for higher access
speed (Behrouz 2016).
ix. The company will be supplied internet by the internet service providers using the
fiber cables internet.
2.2 The Proposed Network requirements
Below are the proposed network’s requirements that will be considered in the network designing
and implementation processes.
i. The network should have maximum uptime of 99.9% per day.
ii. The network bandwidth should be at least 600 MHz or higher.
iii. There should be access to internet in all subnets.
iv. There should be printing facilities in each subnet.
v. Network should allow data transmissions rates of 500 MBPS or higher.
vi. There should be file storage and sharing over the network using network’s servers.
vii. There should be network downloading speed of not less than 300mbps.
viii. There shall be a network uploading speed of not less than 150mps.
2.3 The network connections Media
Below are some of the connection media where their respective prices are recorded to enable
easy budgeting of the networking materials, these media will be used in the connection of the
routers, switches, network printers and the computers in the subnets as summarized below
(Douglas 2017).

i. Low acquisition prices.
ii. Are installed and configured in

This is the media chosen to enable the
connection between the subnet main switch
and the subnet router and it is better than
cat5e cable in terms of speed and bandwidth
and therefore selected due to the following.
i. Low acquisition prices.
ii. Are installed and configured in
the network easily.
iii. They have quite high data
transmission rates of 1-10gbps as
required in the network
iv. They support data transmissions

This media was selected to do the router to
router connection between the subnets and
the head office subnet and is recommended
due to higher transmission rates and longer
transmission distance and thus better for
internet connections, below are other
features that made it to be selected.

i. It supports up to 10gbps
transmissions rates.
ii. It maintains highest uptime
compared to other media.
iii. It can transmit data for 1- 5
kilometers per second.
iv. It has lowest latency thus
allowing high transmission rate.
v. It is able to withstand any
electro-magnetic interference.

network branches where the switches are used to link the end devices together while routers link
the branches subnet-works to the main router in the head office.
