Preliminaries Description
This is an information communication network proposal intended for the AusEd
Incorporation learning system. Recently the Maryland assembly approved enough funding to
Your Name 2018 2

cater for the execution of the proposal (Campbell, 2018). The administration of AusEd
Incorporation has chosen to evaluate the current IT infrastructure to support the increasing need
for improved services for students and the staffs. Financing will be required to execute the
proposal.
System Scope
The suggested network is intended to support the three departments in AusEd namely:
Sales, Operations, and Course Delivery. The Sales department manages marketing and sales
processes. The department is as well responsible for course promotion and managing. Each
regional office has four departments that should be attended. The Courses Delivery department is
in charge of teaching as well as assessment, developing course materials, and learning
management (Roldán Bravo, Lloréns Montes, and Ruiz Moreno, 2017). The Operations
department controls all the main operations like information systems, accounting, and human
resources management. AusEd has about two thousand full time students as well as about a
hundred workers more than 50% of whom operate on part-time, a casual basis.
Network Objective
The proposed network is planned to accomplish numerous specific operational/business
objectives:
1. Safe Service: The fundamental aim of the network system is to offer safe managerial
computing services to the incorporation’s three divisions (Laudon, and Laudon, 2015). It is
planned to be physically and functionally isolated from accessibility by individuals who are
not employees of the AusEd Incorporation education scheme hence minimizing the danger of
illegal use.

2. Update and Integration: Currently there are several LANs (Local Area Networks) in
the company’s learning system, however most of the equipments used are outdated, several
LANs are not compatible with one another, and not linked to system-wide
networks(Hernantes, Gallardo, and Serrano, 2015). This suggestion defines a WAN (Wide
Area Network) that updates and integrates these local area networks to support fruitful
collaboration through the system.
3. Processing of Versatile Data: The network is intended to facilitate users to recover,
process, as well as store non-ASCII as well as ASCII text, video, still graphics, as well as
audios from any linked PC.
4. Collaboration: This network should combine the capabilities and power of different
equipment in the AusEd Incorporation to offer a collaborative intermediate that assist users
to combine their expertise irrespective of their locality (Hernantes, Gallardo, and Serrano,
2015). A system will allow individuals to share ideas and information easily hence they are
able to work more productively and efficiently.
5. Scalability: The network is scalable, therefore more departments can be included when
funding becomes accessible without redoing the fitted network.
Network Design
The key consumers of the design at the company’s level should be the ten members in the
Curriculum Division, three secretaries, three administrators, eight members in the department of
Human Resources, six members in the Accounting/Finance Department, as well as three
members in the Computer Service Division (Ajamieh, Benitez, Braojos, and Gelhard, 2016). At
the regional level the key users should be four secretaries, four administrators, four participants
in the Computer Service Division, sixteen members in the Human Resources Department, as
Your Name 2018 4

well as two members in the Accounting /Finance Division. Pre-service tutors, Parents, public,
and the teachers are secondary consumers of the design because they will get information
produced from the network, however they cannot use the system directly (Borena, and Negash,
2016).
Design Expectations. This network design undertakes the following (Andersen, Kasparick,
Ulrich, Franke, Schlamelcher, Rockstroh, and Ingenerf, 2018):
1. The AusEd Incorporation Learning Network contains a firewall, which safeguards all
information entering and leaving the network.
2. Internet services are offered by NBC (National Broadcasting Company) Network,
supported by the administration of AusEd Incorporation.
Network Analysis
Types of Data. The kinds of information that the system will serve includes; reports,
bulletins, web pages, accounting information, and personnel profiles (Bouchard, Dysert, Farshi,
Garber, Hackett, Lal, Mishra, and Pillai, EMC IP Holding Co LLC, 2017). Most of the
information will be non-ASCII and ASCII texts, however some still images and perhaps a little
measure of video and voice will be there (mainly for computer-based coordination).
Data Source. The formation and exploitation of data is done at every end station on the
structure (Liu, Li, Lin, Kang, and Xiao, 2017). Some software applications found in Windows
10, mostly Dream Weaver as well as Office 2013 Proficient (Word, Outlook, Excel, PowerPoint,
as well as Access) will generate the data. Other sources of data to be served at least on a
restricted basis will be Windows 10 Fixtures (Notepad and Paint), NetMeeting, Photoshop, and
Media Player. It is worthy to remember that the system will never be accessed from outside.

Priority Levels and Numbers of Users. At the AusEd Incorporation level, the consumers
will be secretaries, administrators, as well as members of the three divisions. At the department
level, the consumers will be secretaries, administrators, and participants in three divisions
(Lindörfer, and Mansmann, 2017). The maximum users projected for the system at any specific
time is a hundred: thirty regular users in Sales department, thirty regular users for the Course
Delivery Department, thirty-three regular users at the AusEd Inc level, and seven unexpected
users for the Operations department.
Three urgency stages will be served: management (top prioritized), user (medium
prioritized), as well as background (low prioritized). These titles do not match to administrative
ranks in the AusEd Incorporation learning structure; however, they are system service ranks.
Network management procedures will be given top-priority services; most network procedures
will be given medium-priority services; a few procedures (like, backup, and e-mail transfers) will
receive low-priority services (Hernantes, Gallardo, and Serrano, 2015). It is important to note
that, system management will generally use a little measure of the bandwidth available; this
meaning that user processes and management will enjoy equal support. Background procedures
will as well get more than enough services, however they should be deferred as desired to
continue supporting the user and management services.
Speed of Transmission. The system will be clear to the consumer. Consequently, file
transfers, as well as remotely implemented applications should preferably appear to function as
fast as processes implemented in an end-station (Leitold, Arrott, and Hadarics, 2016). Dialogues
with consumers so as to establish their expectations and needs show that an ordinary throughput
of 10 mbps for each user among local area networks and 20 megabits per second per user in each
Your Name 2018 6

LAN will hence more than back the necessary performances in most circumstances
(teleconferencing is a possible exclusion).
Load Difference Estimates. Dialogues with consumers and surveillance of the use of LAN
at the three levels’ average data produced per hour as well as highest loads from February to
April, year 2001. The received data are presented in the appendices. The data show that the
maximum average traffic size will happen from 9:30 a.m. - 7:30 p.m., from Monday to
Friday. The highest network traffic size is anticipated twice per day: 9:00 a.m.-12:00 noon as
well as from 5:30 p.m.-7:30 p.m (Berger, Chen, Hu, Pendarakis, Rao, Sailer, Schales, and
Stoecklin, International Business Machines Corp, 2017). During night hours and during
weekends the system traffic is slight apart from the day-to-day backup of the computers to the
local area network servers within the regions and some batch data transmissions expected from
the regions to the company (AusEd Inc). The data show the following system design parameters:
 The average essential output on all local area networks during working time (7:30 a.m. -
6:30 p.m.), approximately 0.2 mbps only.
 The average necessary output on the wide area network during working time (7:30 a.m. -
6:30 p.m.) will be 0.04 mbps only.
 The peak anticipated traffic on each local area network will be approximately 100 mbps.
 The highest expected traffic loads on the wide area network will be approximately 20
mbps.
Of course, for the sake of avoiding user grievances, the system is planned for the highest traffic
loads and not for the average traffic loads.
Storage Necessities. Storage should be big enough to accumulate all teacher, student, as
well as AusEd Inc information (worthy to note: student information is information about students
Your Name 2018 7

but not data created by students). Discussions and experiences by users’ anticipated and present
storage necessities show that each consumer will have at least 100 MB space of the server (also
to secondary storing on local computers); the maximum projected server-side capacity
requirement per every user is approximately 1.5 GB. In addition, the network’s OS will occupy
around 550 MB on every local area network server. Considering an issue of price-performance,
each computer will possess a minimum capacity of about 10 GB, each one of the LAN servers
will contain a minimum capacity of about 20 GB storage. The central server within the company
will have about 36 GB storage capacity (vom Brocke, Braccini, Sonnenberg, and Spagnoletti,
2014).
Reliability Requirements. To maintain industry standards and the user expectations, both
the WAN and the LANs are supposed to operate at least 99.9 percent uptime while undiscovered
error is supposed to be at a rate of 0.001percent (Avram, 2014).
Security Requirements. A firewall is necessary to restrict any unauthorized user. Part of
the safety will be User account and a password that will limit accessibility(Avram,
2014). Different accessibilities for network users and managers will be there.
Existing Network: The head office of AusEd Inc is located at Darwin, technical team
maintain an accounting structure running registered MYOB program, a client association
administration system utilizing open source email system based on Microsoft Exchange Server
2007 and SugarCRM software (Roy, Moitra, Das, Srinivasan, and Malhotra, 2015).

Justification for the chosen hardware
One goal of business owners is to reduce cost and increase output. To do this it is important to
assess the areas where time can be optimized and reduce unnecessary costs (Leitold, Arrott, and
Hadarics, 2016). LAN network will benefit the institution in the following way:
