CP5631 Network Redesign: Data Analytics Company Expansion Plan

This report presents a comprehensive network assessment and redesign for an Australian data analytics company expanding its operations. The project involves designing a new network infrastructure, subnetting network branches with unique IP addresses, selecting appropriate network hardware, estimating the network's budget, and analyzing cloud computing adoption proposals. The primary objectives include providing internet access, wireless network access, shared databases, web services, data backup, and cloud computing services across all company branches. The report details the subnetting process, assigning IP addresses to various network segments, and includes a weighted decision matrix for hardware resource requirements analysis. It also evaluates different cloud computing options, providing recommendations for the company's network infrastructure development. Desklib is a great platform for students to find such assignments.

Network Assessments and Re-Designing
PART 1 - Executive summary
This is a report about an Australian data analytic company that deals with scientific analysis in
Australia and it is currently having network but the management team had requested the network
to be done assessments for it to be re-designed to allow the new network to be designed and
installed in order to accommodate the new branches of the company that had been opened and
thus requiring to be fitted with new network equipments.
This project is done with a purpose of designing the new network, allocating the IP address to the
network subnets and computation of the estimated budgets for the new network installation and
implementation.
The project covers a wide scope where various activities are involved which includes sub-netting
then new networks branches where each branch is assigned a unique IP address, identifying the
network hardware devices to use in network installation, approximating the expected network’s
budget and also to analyze the various proposals for adopting the cloud computing and thus the
management will be able to prepare on the network installation process.
In this project there are various objectives that are aimed to be achieved which includes:
i. To provide the internet access to the company’s entire branches.
ii. To provide the wireless network access to the company’s branches local area
network.
iii. To provide the shared databases Facility.
iv. To provide the web-services to the network users and staffs.
v. To provide the back-up Fa cilities to the network users to backup data and
information.
vi. To provide the cloud computing services to the network users.

The below table shows the number of the IP addresses that are required in the various network
subnets where each location is allocated the IP addresses depending on the number of work
stations.

Subnetting
The sub-netting is a process of assigning the IP addresses to the network sections that are in
various branches of the company, where the IP address space purchased by the company is
130.0.0.0/20 which is a class B network address and it will be used to assign the subnets IP
addresses, in order to assign the accurate number of IP addresses the Total Hosts are calculated
where each host will require a unique IP address , subnet masks, broadcasts address and the
address ranges, however the subnet addresses to be assigned in each subnet will be able to allow
network expansion since the Total Hosts in the LANs is expended to double in the course of five
years.
Below is the calculation of the subnets IP addresses.
Sydney branch
The branch has 800 workstations that are located in the LAN and there are 30 IP addresses that
are in the WAN and therefore a total of 830 IP addresses are required.

PART 4 - Researching and sourcing appropriate devices.
Executive summary
The implementations of the proposed network there are various devices that will require to be
interconnected to form the network, these devices are associated with some costs and thus the
management require to get the approximate total cost that might be incurred to fully install the
proposed network, the items will therefore be acquired using the procurement’s plan that will be
set to achieve the following goals.
i. To make sure the devices to be used will be appropriate for accommodating all
workstations that are targeted to be used in the whole network branches and wireless
networks.
ii. To make sure all the selected devices are efficient and able to provide best service to
the network users.
iii. To make sure all devices selected are durable and they able to serve the users without
any fault arising.
iv. To make sure that during the devices acquisition processes the budget sets of $10000
is not exceeded.
