Designing a Network Infrastructure for AusEd Institution

Introduction.
When it comes to interact with the network infrastructure where we have been asked to perform a
certain analysis then it might be a challenge for us as we strive to get to know what we are required to
do if we don’t not have the necessary knowledge. Network can be explained to be a group of hardware
devices and the components of software’s which will be necessary when connecting the devices in an
organization to other many organizations and the specific internet used. AusEd institution is in a position
where it is in need of designing a network that is estimated to server almost 3000 hosts in the
institution. As the IT manager we are required to give sense to the management of AusEd to what we
are needed for us to achieve their needs. The understanding will be majored in two components as
explained below.
1. Hardware Components- these are the physical and tangible devices that are utilized in the
networking environment such as the routers, servers, hub, printers, switches, modem,
transceiver, cabling, network interface cards and the phone lines among many others.
2. Software Components are those components that are known for utilizing the environment of
the network services and all the needed protocols in enabling the hardware devices to
communicate and interconnect with each other.
An operating system can only be understood and installed only after the hardware have be installed and
configured as well as installing the software in the network infrastructure. The operating system is on e
of the major components used in the networking as it is used by the server in managing all the resources
that are transmitted from one device to the other. Network IT infrastructure is referred to as group of
physical hardware and the logical components which is needed in providing some features over the
network which may include the network security, the access control, network security, Routing and the
capabilities of switching.
There has been a rapid growth in the world of technology where each and every day we get new
technologies and new versions of what we were using yesterday so it should always be wise in knowing
where we belong as the future will need something else. AusEd is entitled to have us know what they
have that can be used in the proposed setup of the network design. This will be done by doing an
analysis of the whole institution so that we know how to plan for what we will need and the appropriate
flow of information from the devices in the entire network (Adato, 2015). The network to be set is
based on the needs of the organisation where we have to consider the following issues.

1. Security issues
2. Scalability
3. Reliability and accessibility
4. Management where it must be easy when we are doing some troubleshooting in case a problem
arise.
The project is to help us give out the model to be used in designing the network. The idea will be
explained where we have to describe the project, the scope of the project, the purpose of the case
study, the assumptions that have been made, the list of the devices to be used when networking, the
system design logical diagram, justification of the applied hardware’s and the conclusion which will give
a summary of what we have analysed in the other areas.
Description of the Project
The management of AusEd is in need of a network and we will have a giant construction to the
implementation of the proposed network design. From the description we have to start the plan of the
infrastructure where we will base it on the resources available and what is needed in making the work
complete. There are some objectives that need to be achieved at the end of the day. There is already an
existing network. Their idea is to improve their relationship with their customers where they are
considering to use the Customer Relationship management software’s and the Microsoft server 2007
which will be used when we are exchanging the emails through sending and receiving. When we say we
want to do the plan it may sound easy but when we do a feasibility study and understand the following
points such as the ratio of the servers to the number of hosts (Workstations), the expected size of the IT
infrastructure, mixing the platforms, building a fast network may be a big challenge when determining
how the network will be designed.
Scope of the Problem and its Purpose
Designing the IT infrastructure of AusEd will help them in determining the strategic plan which is
classified in to two concepts where they are looking in to a future where they will be able to increase the
resources through the diversification of the sources of fund and minimizing the all cost that results ot all
the core-non activities. After understanding the strategic plan then we are required to understand the
technology plan where we will help them in developing an offline Moodle that will help the
management to help the students maintain the personal computers of the school and at the same time
access resources when they are offline but connected to the network. The other development in the

technology plan is coming up with a system where we have develop an add-on Moodle which will acts as
a project where the students will be able to take a Photo exam when they are on the network on their
personal computers and laptops.
The main objective of this project is understanding the network future scalability that will help in
accommodating additional devices in future (Coleman, 2012). We would also a network design that
will be easy to manage when problems arises and when there is need for troubleshooting in cases
when they arise. Also the security of the network will be a great consideration as making this
network design we will need to consider the security of the network and that is why we have told
to explain on the use of security devices and software’s such as the firewalls and the virtual
Private networks (VPNs).
Assumptions Made
When the experts in networking are doing an analysis in the feasibility study of the design of
AusEd network then we will need to do some assumptions as they are explained here below. The
first assumptions is that we expect the AusEd institution to add some devices in the future which
will in turn require us to develop a system that has scalability, flexibility and reliable hence
requiring us to use the three layered hierarchical model. Second assumptions is that we expect
the management of AusEd not to put constraints on the budget such that they will not be able to
make it hard when we ask for the money for the equipment’s hence delaying the implementation
process. Third Assumption is where we take the small logical diagram to represent the entire
system design. Lastly is that the estimate cost of the network devices is just an estimate that will
be used to provide an overview of the entire AusEd network.
