Case Study
Fully Unreal Reality (FUR) is a new and upcoming game development company that is turning heads
in the industry. They have grown so much recently that they must upgrade their network which was
only built 3 years ago but cannot cope with the growth. Management has requested a network 22/02/2021 v1.0
consultant (you) be brought in and a new network designed. They have advised you that the current
infrastructure will be entirely replaced, except for cabling.
FUR has two major headquarters in Sydney and Melbourne and a branch office in Adelaide. Each HQ
has the same floor plan with the branch office being slightly smaller. Currently only the Melbourne
HQ is connected via WAN to the Adelaide office. The management is open to an additional link from
Sydney to Adelaide if it can be justified.
The WAN connection speed is not in scope, nor is the existing Sydney to Melbourne and Melbourne
to Adelaide WAN connections. The ISP connection is to Sydney only.
Each office has multiple different types of devices that need connection and all from different
departments in the office. The FUR organisation hierarchy is outlined below:
• Human Resources & Finance Department
• Design and Development Department
o Software Engineering Team
o Game Design Team
o Quality Assurance Team
• Art Department
o Concept Art Team
o 3D Modelling Team
• Product Department
o Customer Support Team
o Marketing Team
o Training Team
Floor plans for the HQ are given in Appendix A.
The company network must support hundreds of staff and be scalable for up to 5 years. It is
expected yearly growth rates will be 20%. Currently the staff member count at each headquarters is
as follows:
• HR & Finance: 7 staff members,
• Design and Development: 31 staff members,
• Art: 11 staff members,
• Product: 52 staff members.
The Adelaide office has only a fraction of this, and not all departments are in Adelaide:
• HR & Finance: 1 staff member,
• Design and Development: 5 members,
• Product: 3 members.
Each department must be separate on the network, with HR & Finance having the most need to be
separate from other departments. Art staff regularly take home tablets to design at home and on
the go, these tablets are connected via Wi-Fi to the company’s internal asset server while at the
office (Internal Wi-Fi). Art staff also have a PC available at work for them.
Design and Development staff bring their own company laptop to work (to connect to the Internal
Wi-Fi) and can also access 5 computers available at work for machine learning and graphical
processing abilities. The product team works on desktop computers, one per staff member.22/02/2021 v1.0
HR & Finance staff members each have a desktop computer and are not permitted to take any
devices home (given the nature of their work). HR & Finance is responsible for handling very
sensitive data and must be separate from other departments.
All staff bring their mobile devices and smart watches to work with them and expect to be able to
use the Internet on them at work, there is no restriction on them accessing the internal server
because they are employees of the company.
Corporate training happens at all offices, a training Wi-Fi network is required for any guests
attending. This Wi-Fi network must only have access to the training server located in Sydney and the
Internet. Involved in corporate training is often audio and video conferences with other offices.
The company itself has several servers: a web server, an asset server, two game servers, a file server
and a training server. All servers are located in the Sydney headquarters. The web server must be
accessible from the Internet on HTTP and HTTPS. The game server must be accessible on UDP port
65532 from the Internet. No other server should have access to the Internet or be accessible from
the Internet. The company also has 3 printers in each headquarters, Adelaide has 1 printer.
Given the sensitive nature of what is created by the company, security cameras are featured in and
around each office to make sure employees are doing the correct thing. This also helps with
preventing unauthorised personnel from gaining access to the offices. Security cameras should
continue to operate for up to 30 minutes after a power outage.
Out of Scope
• The existing WAN connections between Adelaide <-> Melbourne, Melbourne <-> Sydney,
Sydney <-> ISP.
• VoIP, although planning for it is advisable (reserving a VLAN, etc).
• Wall cabling, device cabling is still necessary.
• Server specifications and end device numbers.
• Equipment space availability/layout of the offices, see Appendix A.
• VPNs or related software to support working from home/on the go.
Assumptions
• Wireless access is required at all offices.
• FUR plans on expanding rapidly within the next 5 years (adding new locations).
• Different categories of users/devices should be in their own VLAN.
• Each staff member has access to at least one company device.
• Space is available in each office for networking equipment.
• Cables exist already and are Cat6.
• The network address given to the ISP <-> Sydney connection is 205.169.255.4/30 (ISP has .5,
Sydney has .6).
• Private network address space must be used.
