Assignment 1 – FIT9137 S2 2020
A Request For Proposal (RFP) to Design Wired LANs, Wireless WLANs and
support Backbone Wide Area Network (WAN)

1. Assignment Description
Objective
A public transport company requires its office building to be connected over a wired LAN and
Wireless LAN (WLAN). You have been asked to respond to the following excerpt from their RFP
(Request For Proposals) in the newspaper.
Scope of the Work
At present, the total number of office employees in Melbourne is 200. Each office worker is provided
with an office space or cubicle with a multimedia desktop having wired network connection. Owing
to a business acquisition, the number of employees at Melbourne is expected to increase
substantially. The size of the Melbourne office, both Wired and Wireless LAN will increase (from
200) to 600 stations; after two new 4-storey buildings (located across the road) have been acquired
to accommodate the additional office space needed to provide seating arrangements for the increased
number of employees (see Figure 1).
The new buildings have already been wired for network connections, where each floor has a wiring
closet with necessary structured cabling. Each wiring closet has four fiber optic cables running to a
dedicated server room in the basement. The two new buildings also need a Wide Area Network (WAN)
to be connected to the existing Main office network (across the road).
Note: Lift & Services wells area is the space used for Lift service, Wells used for running vertical
network cables between floors.
It is envisaged that the two new buildings in Melbourne office would support, both, wired and wireless
networked office environment where each of the staff PC and their personal laptops would be equipped

with office desktop high resolution video conferencing software (VoIP), along with the usual business
applications such as web, email, and regular office productivity packages. It is anticipated that the
average network traffic generated by each active user is estimated to be around 15-20 Mbps. The
expected user activity pattern for both the new buildings may be seen in Figure 2, where each of the
new buildings will accommodate 200 new staff members. The Wired LAN infrastructure needs to be
designed to support the anticipated peak time data traffic, and in addition, support the Wireless LAN.
The design should show the WLAN Access Points (AP) connectivity to the wired infrastructure. At
the existing main office network (across the WAN), a capacity increase will be required for key devices
and their support infrastructure (e.g. Servers, Routers and/or switches) to accommodate the increased
traffic volume from the new buildings. Employees are expected to access the main office network and
its resources frequently. So, from the business perspective, it is important that the WAN connectivity
is maintained all the time. Loss of productivity is not an option from the network connectivity point of
view.
2. Assignment Requirements
The technical report should contain the following important diagrams to support your proposal:
(a) A conceptual high-level diagram showing a typical floor plan, backbone network (connecting the
floors) and a wide area network to connect to the main office.
(b) A typical floorplan (only one floor would be sufficient).

(c) Servers, Routers, Switches and Access Point (AP) locations.
(d) Backbone connection diagrams (using schematic diagrams of cross-section of a building showing
switches, routers etc.).
(e) WAN connectivity for two new buildings connecting with the head office building.
Include the following information in response to the request for Proposal (RFP):
(a) Project Requirements: Project requirements 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.
(b) Wired, Wireless LAN and WAN Design: Wired, Wireless LAN design (for a typical floor) and
WAN design, must include the following information:
(i) Computer desktop layout plan with network topology for a typical floor level.
(ii) Switch and Wireless Access Point locations on a typical floor, vertical cable paths and
lengths between the floors. Switch and Access Point functional specifications. Assume the
floor to ceiling height as 3 meters approximately including the false ceiling.
(iii) Router (and/or Switches) locations (both the existing and the new ones) and their
interconnections providing WAN connectivity.
(c) Design Rules (or Assumptions): You need to outline design rules for LANs, WLANs, and WAN.
Your description should include:
(i) Detailed steps required in the network design process,
(ii) Methods used to form estimates of network performance for each types of devices,
(iii) An example of a basic sample design showing proposed floor plan, assumptions,
justifications, and calculations.
(iv) Assumptions of backbone connectivity using wired/wireless media needs to be reported.
(d) Recommendations and Justification: A summary of your recommendations with a statement of
justification.
List of equipment, their specifications, technical data, and device related cabling specifications etc. should
be included in the Appendix. Appendix can be used only for report referencing purpose only. Appendix
should contains technical data relevant to the design from the manufacturer of the hardware selected.
Research and analysis expected in the technical report
In the RFP, the company expects you to give them enough arguments in support of your network design to
convince them, with respect to costs and benefits of the proposed network and new technologies you have
proposed. Go into some technical detail explaining differences between technologies. Give detailed
explanation of the proposed technologies that would be integrated in the network design. It will be useful to
create tables and figures for some of the comparisons. You can answer questions such as:
(a) What devices, switches, Access Points, Routers etc. are involved in each option and what are
their functions?
(b) What kind of (wired and wireless) network technology should be installed in the new buildings
to support the network infrastructure and communication needs?
