Brief of the Organization
The advertising firm Priority Advertising is a medium sized organization that serves in the
marketing and advertising sector. There activities of the firm include film production, creation of
advertisement media content and high-quality printing of advertisement banners and posters.
Project Goals
The new network is to include a solution for Priority Advertisement so that they can use their newly
set up office at Brisbane CBD.
The new network is to provide connectivity services to the workstations and printers for all the 95
employees that are to work in the location of Brisbane CBD.
The new office that has been set up in the suburbs of Brisbane is five stories tall and is to house a
department in each of these five floors.
The organization has also expanded in other cities like Toowoomba where they need to cater
increasing demands from customers for interactive advertisement content such as video
presentations.
The network therefore must also include the small office that have been leased in Toowoomba
which consists of one department only – the advertisement media department.
The employees of Priority advertising should be able to obtain email services from the web mail as
provided by the ISP both from office and from homes.
The company should additionally be able to internally manage email accounts for their employees
and updates to their mailing domain should not be interrupting the services offered by the company.
The managers as well as the employees must be able to share large volumes of data over the
network at any time of the day which includes film files ranging in sizes from 5GB and up to 20GB.
The organizational members must be able to back up sensitivity and important files in a safe and
secure manner in the office building of Brisbane only.
These files that have been backed up should be accessible to department managers present in each
department of both the branches.

4NETWORK SET UP AND SPECIFICATIONS
It is required that each of the colour printers which can be used for printing storyboards containing
large amounts of graphics content be accessible to all the members of the organization.
These printers are to include printers for each department in each of the five floors of the Brisbane
office, one in Toowoomba office as also a separate private printer for the administrator at
Toowoomba.
Each of the departments of Priority Advertising include the Advertising media department present at
Toowoomba small office.
The networks of all departments must come with support for wireless network connectivity through
individual WLAN networks set up for each department.
The company is to obtain internet access through the major network 194.32.9.160 from the ISP and
perform IP addressing based on the IPv4 protocol.
Every department of Priority Advertising must have their own networks that are independently
manageable and well segmented from the networks of other departments.
Members from both the branches Brisbane and Toowoomba of the company Priority Advertising
should be able to communicate with one another and should be able to seamlessly connect with the
internally managed servers the respective purposes.

Network Design
Figure 1: Network Topology Diagram for Priority Advertising
The diagram above presents the full network topology of the proposed network solution for
Priority Advertising (An et al. 2017). The overall network of Priority Advertising includes set up of
two major network segments for both the branches of Brisbane suburbs and that of the small office
in Toowoomba. These network segments both obtain T3 Ethernet network access from the ISP or
Internet Service Provider using the same major IP network (Jiang, Guo and Guo, 2018). The ISP is
hosting mailing services which becomes available to each network segment of Priority Advertising
through web mail applications. The network segment of the Brisbane CBD office comprises of a
router, a L3 multilayer switch, and 6 L2 access layer switches. The multilayer switch obtains the
routed network from the branch router and distributes the network connections to all the six L2
switches, five of which are providing direct connections to the hosts of the respective departments
on each of the five floors of the building of the new office while the other L2 switches is providing
connections to the file and mail server. Thus, the network at Brisbane office forms a three-layered
hierarchical model of networking architecture and hence presents with a very efficient network
design for connecting the hosts (Wang et al. 2018). The network segment of the Toowoomba office
on the other hand consists of one router and one L2 switch which directly connects all the individual
devices of the small office of Toowoomba after obtaining the routed network from the branch router
(Raumer et al. 2016). The network of the Brisbane office consists workstations, printers and wireless
access points in the departments of at each floor of the Brisbane office building while the backup file
server and the email server are placed at the first floor along with the branch router. The type of
workstations and their role is specified in the diagram. The network of Toowoomba consisting of one
department is on a single floor and the different types of workstations are labelled in the diagram.
This network segment also consists of printers as well as wireless access points that are required to
set up the WLAN network Gal et al. 2017). Both the networks of Brisbane CBD and the Toowoomba
locations follow the top down networking approach to implement the networking infrastructure.

Activity 4
Shared Components
The shared components that have been identified from the overall network of the company
Priority Advertising are the public use printers that have been placed in each of the departments of
both the network segments (Koeller, Lewis and Pooley 2019). Other than these printers, the backup
File server is among the most important shared component that is being shared over the network.
The organizational members are also to enjoy email services that is being provided by the ISP. These
are soon to be managed from within the organization through the Mail Server (Vanwinkle and Kodi
2018). The File server is so store and back up all kinds of relevant information starting from
confidential business data, employee and human resource information, diagnostics and
configuration data of the network as also large volumes of data regarding the graphics and video
production content of final outputs and therefore requires significant storage and processing power
(Monge et al. 2018). The Mail server should also be able to store the mailbox data of all the
members of the company including the media attachments and hence also requires equally
substantial storage as well as compute power. The printers that are being shared are all
multipurpose laserjet color printers that is these printers can also perform the roles of scanners and
copiers while also delivering high quality print outs (Han et al. 2015). The private use printer that is
installed in the room of administrator in the Toowoomba office is specifically for use by the
administrator for safeguarding confidential data. However, access to this printer is only physically
isolated. The network still allows print orders to be sent from other users since the administrator
may be in need of documents from other members.
Activity 5
Internet Service and Installation
The internet services are being provided to the overall network of Priority Advertising
through the Internet Service Provider (Green et al. 2015). The ISP at both the locations of Brisbane
CBD and Toowoomba are directly providing services to the branch routers through their own router.
This is how they are letting both the network segments be connected over the same major network
that has been made available (Han et al. 2015). The type of connection that Priority Advertising is
purchasing from the ISP on a subscription basis is T3 Ethernet network. This means that the
company is regularly receiving over 40 Mbps of network bandwidth. This is the minimum Internet
speed required to allow transfer large files of up to 20 GB in less than an hour. To implement the
network and make sure that it is also reliable at the same time, static IP address was requested from
the ISP for configuring both the routers of branches Brisbane and Toowoomba (Peterside, Zavarsky
and Butakov 2015). These static IP addresses are assigned on the serial ports to set up the wide area
network (WAN) between the two branches via the ISP router. Then network segmentation has been
done so that the subnetworks of each department can be individually managed and can be secured
from security risks by isolation of network segments (Ibrahim 2017). Other than that security in the
overall network has mainly been applied by means of IPsec point to point VPN configured on the
routers manufactured by Cisco (Bensalah, Kamoun and Bahnasse 2017). The connection between
the routers is performed with serial cables, after which the connection between the router and the
switch takes place via straight through Ethernet cables. From one switch to another, connections are
made with crossover Ethernet cables and the end devices are directly connected to switches with
straight through Ethernet cables.

Activity 7
Security Concerns and Mitigation
With the type of connection that has been set up for Priority Advertising, the network can
become vulnerable to external cyber security threats if the IP addresses of the networks of the two
branches get known to the attacker (Vallejo, Feferman and Rothenberg 2018). To mitigate this
problem public IP addresses are assigned to the network users who are connected within the private
LAN by use of the NAT or Network Address Translation process (Meidan et al. 2019). This process is
also at times called SNAT or Secure NAT (Hossain et al. 2016). When configured in routers, the SNAT
router replaces the source IPs with IP addresses configured on it. Since this is not the actual IP
address of the device, it prevents exposure to external threats (Vasilakos et al. 2015). In many

9NETWORK SET UP AND SPECIFICATIONS
scenarios the network administrators do not define these simple mappings, rather they set up
policies for allowing the gateway device for assigning the mappings depending upon the destination
involved in the communication (Yu et al. 2017). Another method of securing with public and private
IP addresses is by translating the IPv4 address to their respective IPv6 addresses which is not the real
IP however makes the communication compatible with IPv6 based networking environments none
the less.
