1. Project Preliminaries Description
This particular project report is mainly depending on AusEd, it allows of online education
facilities in Information Technology as well as Business to numbers of students in the whole
world. However, AusEd is also very much committed to the learning system. This particular
organisation decides to make more improvements in their network infrastructure which helps to
allow educations in more efficient manner. The implemented strategic plan of this organisation is
to raise the income with the help of diversification of all funding sources. Apart from that, the
second plan is to decrease the costs of various non-core activities, which supports in doing both
technological and operational development of AusEd. The AusEd management decided to
review the already implemented information technology infrastructure that assists to increase the
better services demands for both the students and staffs. Apart from that, the AusEd study centre
offered numbers of workstations and student’s computers supporting all crews to enquiries all
academic opportunities, different multimedia meetings based on the video conferencing art,
separate tutorial meetings in all available rooms available for all study groups. With the help of
available online education, all students get engaged with all other fellow students and also
different staffs, professors for doing better interaction with all available people.
2. Purpose and scope of the problem space as well as business context
The already available system of AusEd mainly consists of the accounting system using
proprietary MYOB software as well as customer relationship management system that mainly
used as open source SugarCRM software and also a proper Email service depending on
Microsoft Exchange server 2007. However, the organization mainly decides to do the

IT NETWORK INFRASTRUCTURE
technological development of organization to achieve all the strategic objectives like the
development of different ad-ons to Moodle which helps the students to maintain their personal
computers, local databases used in Moddle discussion forums. Hence, the first possibility is to do
the better development of off-line Moodle. In second scope, it discussed about the development
of add-on to Moodle site which helps the student to complete all exams on their own computers.
Both these two business contexts are taken in consideration because people are accustomed to
use the mobile devices for accessing better internet facility like all educational purposes.
However, the offline moodle is mainly used to enhance as well as development of the mobile
application that helps to increase the better classroom’s facilities and learner’s experiences for
accessing the mobile devices. The AudEd mainly decided to develop Moodle offline for the
better commutation from home to university, work from different locations from where they get
the facility to access better available internet connection. Apart from that, Moodle offline allows
all students to co-ordinate the Moodle servers and different works with available offline clients
to allow access of different course materials and different learning activities. It also discussed
about the photo exam that is taken at various regular interval by using computer’s on-board
camera. The photographs taken includes reliable timestamp and also kept in secure manner
transferred to various central locations where it can be established a proper internet connection.
3. Scope of the system descriptions and assumptions
The AIS helps to track both the income as well as expenses done in AusEd. In this
organization, they used a proper system to track all available company requirements along with
detailed reports of accounts which are receivable and work-in-progress. Hence, the accounting
system helps to generate different financial statements, managerial reports and various other

IT NETWORK INFRASTRUCTURE
reports prepared for outsiders. The organization can also use the accounting system helps to
provide all related information based on overhead expenses and other sales commissions. The
CRM system mainly focused on different business related services of AusEd to achieve better
customer relation and increase of profits. It also helps to reduce the incurred expenses of AusEd
with the better improvement of accuracy of all available study centers. () also highlighted that the
CRM system mainly helps the AusEd to have better perspective based on student’s requirement,
more customer knowledge from different interaction phases of students like fee payments, course
conclusion, admissions etc. However, the information of customers like name, gender, marketing
materials, gender, social media along with different other information from other
communicational channels. All these customer’s interactions can be tracked by doing the better
implementation of CRM. However, the CRM system also be utilized for getting faster services.
In addition, it also helps to identify the better trends for getting the feedback of different
admission purposes, marketing purposes included in different business processes.

The proposed design of an It network infrastructure is mainly used the cloud computing
technique based on different network equipments and devices, using internet to guarantee the
uses of different available computing resources as per demand. Some of the lists of equipments
that are needed to design the IT network infrastructure are mentioned in the below table format:
List of equipments and
devices used of design the
network IT infrastructure
Description
Remote access router It is mainly used to have the access of both computer and network
from various remote distances.
Workgroup switch In LAN, the used workgroup switch is a type of switch with less
capacity that is mainly used to serve various requirements of all
workgroup. However, it becomes LAN equivalent with edge
switch in different public areas network.
Router It is one type of software and device used in computer to
determine the usage of network points helps in forwarding packets
to their destination. It mainly performed different traffic directing
functions using proper internet connection. The forwarded data
packet mainly consists of internetwork till it reached to its
destination node.
Gateway It is a interface that provide better compatibility among all
networks to convert the transmission speed, used protocols and

IT NETWORK INFRASTRUCTURE
other various codes.
Switch It is one of the high speed deice which receive more incoming
data packets and also re-directs them to their destination
mentioned on LAN port. However, it also channels all their
incoming data from different input ports towards output port that
mainly used to forward data to destination.
Network Servers It is one of the computer programs that mainly help to manage all
centralized resources as well as services in the network. It also
helps to manage all available network resources. However, it
mainly serves data to system using LAN over internet. It also helps
to provide all network resources like printer access, hardware
access along with better disk space.
Workstations It is mainly considered as one of the desktop computer terminal
that is mainly networked and also acts as more powerful
comparing with personal computers. However, it also consists of
higher speed of graphics adapters along with different connected
peripherals.
Network hub It is one of the network hardware devices that are mainly
connected with the Ethernet devices to prepare the better network
segments. It also have better input/output port with a proper
signaling introduced at the input of port appears to all outputs of
used ports.

7. Justification for chosen hardware
The proposed network infrastructure mainly consists of both software and hardware
resources that enable the better communications, network connectivity, different operations as
well as better network management. However, it also provided with better communicational path
along with better services among all processes, users, services and other external networks.
However, the networking hardware is mainly used to design all physical devices required for
doing better communication and interaction among different devices available on computer
network. Some of the list of used hardware for used IT network infrastructure is mentioned
below:
Wireless Access Point: It is one of the network hardware that allows the use of Wi-Fi devices
for better connection in wired network. The Access Point (AP) is mainly connected with router
as one of the standalone devices and also considered as one of the integral components of router.
However, the AP is mainly connected with wired local area network like Ethernet and also AP
provided with better wireless communication with the use of wireless LAN technology.
Firewall: It is one of the hardware type used in network to offer the prevention of getting better
communication. However, it also used to maintain the security of private network. However, it
also blocks all unauthorized access with private network. It also helps to prevent access from the
unauthorized web. The firewall also get established to create barrier among more secured trusted
internal network from the outside network like internet that assumed not to be trusted and
secured.
Network address translator: It is also a hardware that helps to convert both the external and
internal network addresses. It also enabled the private IT network that used for un-registered IP

addresses for better connection with Internet. However, it is also operated on router and also
translated the private addresses to internal network in legal addresses before forwarding the
packets to network.
8. Techniques for achieving sustainable global economy and environmental
responsibilities
Now days, the global economy is considered as one the un-sustainable path. In terms of
building better IT network infrastructure, the organization need to achieve better sustainable
global economy. However, the networks are considered that mainly developed better culture of
support which is more effective and sustainable to do the better use of different IT resources. It
also discussed about the strong leadership used to facilitate better supportive relationship
required to create a sustainable network. In this context, () discussed sustainability of network
included of different system users who can benefited from the services created of different
sustainable profiles. However, the user sustainable profiles are mainly required all through
different entry points like direct to network infrastructure sustainability, network partners to
collect all needed data and information in different offline field. In addition, it also helps to the
administrator to have the better understanding networking needed in virtual environment for the
improvement of performance. The IT network plan is basically environment specific as if the
situation varies from 10 physical hosts with 100 virtual machines running in pooled environment.
It also discussed about the physical server environment including of different issues that can be
resolved by doing proper resource management which can be resolved by doing better resource
isolation.
