FIT5083 –Network Infrastructure
S1 2020 Group Assignment
Submission: Assignment is due by Friday of week-12, 4:00 PM. The Report
consist of two Parts: Part-1 & Part-II
Part-I: A Network Infrastructure design for enterprise network:
A request for proposal (RFP) to design a new Wired & Wireless
Local Area Network LAN and Backbone wide area network (WAN)
network design report.
Group formation: In each tutorial please form a group of 3 to 4 students to work on the group
assignment. The assignment specifications are in a form of request for proposal (RFP) which is a
solicitation, often made through a bidding process, by a company interested in procurement of an
installation contract service to potential suppliers to submit a proposal. This group assignment
provides an opportunity for you to work in a project as a group member and apply data
communications and Computer networking concepts to a practical network design. You will be
required to analyze a case study and make networking recommendations based on the RFP
requirements. This assignment will also allow you to present your solutions in a formal reporting
format. Contributions from individual members of a project group will be described in the formal
report. Peer assessment component will be discussed; Forms such as Individual load factor and
Group load factor will be used to access individual and group contributions. Such data will be used
to individualize student marks in cases of substantially inequitable work put in by members of a
given group.
You should supply the following information in response to the request for Proposal (RFP):
Task -a) Project requirements brief can be derived from Objectives and Scope of Work
section of the RFP. A requirement brief is usually an itemized list of the client’s
requirements derived from the RFP.
Task -b) Wired & Wireless LAN design for a typical floor, which includes the following
information:-
1. Computer desktop layout plan with network topology for a typical floor level.
2. Switch/Wireless Access Point location on a typical floor, vertical cable paths
and lengths between the floors. Switch/Access Point functional specifications.
Assume the floor to ceiling height as 3 meters approximately including the false
ceiling.
Task -c) Recommendation and justification of the structured cabling selected, Access
Point (AP), Switches i.e. distribution layer, building backbone cabling and media
type to be used for a typical floor level and for the connection across the road to the
existing LAN.

Task -d) List of equipment and the wireless and wired specifications, technical and cabling
specifications. Note: Specifications/Technical details should be included in the
Appendix.
Task -e) You need to outline design rules for a computer LAN, WLAN & WAN network
and describe it in detail. Your description should include:
a. Detailed steps required in the network design process,
b. methods used to form estimates of network performance for each access point
taking into account the types of antennae and wireless protocol,
c. An example of a basic sample design showing proposed floor plan, assumptions,
justifications and calculations.
d. Assumptions of backbone connectivity using wired/wireless media needs to be
reported.
e. Your new design should include IP addressing strategy for both the acquired new
buildings
Write a report of maximum 5000 words, not including diagrams and pictures (you can write a good
report in around 3000 words).
Description of Wired & Wireless LAN Design
The submission of the assignment will be in the form of a Technical report write-up with
explanatory figures and other requirements for reporting. The specifications are as follows.
A public transport company requires that its office building be connected over a wired LAN &
Wireless LAN (WLAN). You have been asked to respond to the following excerpt from their RFP
(request for proposals) in the newspaper:
About Return2Fender Transport Company
At present, the total number of office employee is 700 with 200 in Sydney & Melbourne and 100
each in Adelaide, Brisbane, and Perth. Each office worker is provided with a multimedia desktop
with wireless network connection. Owing to a business acquisition, the number of employees at
Melbourne is expected to increase substantially.
Objectives and Scope of Work
The size of the Melbourne office both Wired & Wireless LAN would increase/expand from 200 to
1000 stations; after two new 10-storey buildings from across the road have been acquired to
accommodate for the additional office space needed to seat increased employees, see Figure 1.
The new buildings have not yet been wired for the LAN or WLAN. The buildings also needs a
WAN to be connected to the existing office network (from across the road).
3 | P a g e
It is envisaged that the two new building in Melbourne office would support a both wired &
wireless networked office environment where each of the staff PC would be equipped with
desktop high resolution video conferencing, VoIP alongside the usual business applications
such as web, email, and regular office productivity packages. It is anticipated that the network
traffic generated by each active-user is estimated to vary between 15-20 Mbps. The expected
user activity pattern for all new buildings may be seen in Figure 2. The Wired LAN
infrastructure needs to be designed, which should support the anticipated peak time data traffic,
and in parallel you will design Wireless-LAN to support LAN.
The technical report should contain the following three important diagrams to support your
report.
4 | P a g e
Diagrams:-
For a typical floor of any one building and a typical building you are required to supply the floor
plan and for any one building floor-to-floor cross connect of network communication.
( 1 ) A typical floor-plan for any floor,
( 2 ) Each Building floor switches and Access-point (AP) locations & inter-connections to
building, and for each building switch and routers backbone connection diagram with cross-section
of a building.
( 3 ) IP addressing strategy, Location of Switches, Routers, Access Points. Focus on optimized
design.
(4) For the entire network you will be required to provide the WAN connectivity to main head
office network diagrams.
Details of structured horizontal floor cabling for desktop computers, Access points & Switches,
vertical floor-to-floor cross connect structured vertical cabling diagram for a typical building and
WAN connectivity for two new buildings and the Main head office building layout is required.
The technical report should include details of LAN, WLAN & WAN standards used for structured
horizontal cabling, vertical cabling and network topology used should be described, Example of
horizontal Cables and Vertical building backbone cables and WAN communication media
specifications, selection criteria and justifications and recommendations needs to be included.
Part-II: A review of computer networking cable types and
characteristics used in Part-I.
You are required to investigate the types of cables used in your design of computer networks in the
Part-1 and you are required to do research and collect information on cables and its technology in
terms of characteristics, application, use, support, installation and relevant testing tools and
deployment tools required for implementing them in network infrastructure. Please focus and write
on the following Applied Research tasks:
Task -f) Compile a catalog of at least three cable types together with technical, numerical &
characteristics standards of the cables. You should include versions of each basic
cable technology for comparison; and the scope should include the network design
used in Part-I of your modern LANs & WANs design. i.e. cable technology used in
your network design.
Task -g) Describe the examples of all the best application and use of these recommended
cable used in your Part-I network infrastructure design and explain why the
technical characteristics of that cable make it best suited for those applications in
your design.
Task -h) Describe the physical support of these cables and their technologies and network
infrastructure installation requirements in Part-I Horizontal and Vertical structured
cabling for LAN & WAN and WLAN Network infrastructure.
Task -i) Describe all the relevant hardware tools and testing tools required in the use of each
cable type for Part-1 design.

Important notes for Part-II:
 The catalog could be a set of tables or a sequence of paragraphs or both and may include
diagrams or pictures. For example, basic name and description of cable technology and
simple specifications may be included in a table. This may be followed by a few
paragraphs containing more general details as well as examples and justification of usage,
installation tools, training or certifications required, and any other relevant notes or
observations.
 Critical specifications will vary for major cable groups or technologies, and could include
some of the following: Bandwidth; Maximum data transmission rate; Maximum
permitted length; Attenuation or loss ratings; Electrical and optical measures, such as
impedance or numerical aperture; Signal propagation speed; Cost; Termination methods;
Manufacturer; Physical construction parameters such as diameter, material or conductor
twist rates.
 Where cable manufacturer’s data has been used in the formulation of the report, some
sort of citation or URL link should be included for later reference.
 If cable specifications are controlled by compliance or certification to industrial or
national standard, than it would be useful to identify or name that standard.
 Support and Tools may include crimping, training or certification requirements,
installation devices and techniques and compliance testing devices.
