Introduction
This is a report about the Arr company which has a total of six offices which are located in
Melbourne town and the surrounding suburbs, this company management had decided to install a
network that will cover the six offices and enable the communication internally and externally
where the users will be able to share files, send some e-mails, access internet and use the
network intranet.
However in each office there are servers and internet access devices to enable internet access,
however the head office is located in Melbourne city within a story building where it occupies
the top three floors for various office departments including general department with on first
floor with 32 workstations, the marketing department in second floor with 20 workstations and
marketing department in the third floor with 38 workstations.
Therefore the main aim of this report is to design the companies wide area network, design head
office local area network, determination of the wiring connection types to be used in head office ,
to determine the local area network topologies and protocols and drawing of the head office floor
plans.
Designed wide area network solution

The figure above shows the infrastructural design of the Arr company wide area network where
the six offices are connected to their respective local area networks which are made of star
network, in the respective local area networks there are local servers for storing the office
information which can be accesses by the office staffs in the office or outside the office for the
file sharing purposes [5].
However the office networks are locally connected using the switch devices that connects
together the end devices like the computers and the servers the switch also connects the local end
devices to the network router. The routers in the individual offices are then used to link to the
other routers in the other offices to make the wide area network [4].
In the head office there is the internet access point which supplies the internet to the entire wide
area network through the internet service providers, however in the head office the general
department is the one responsible to maintain or offer support to the entire wide area network
and therefore the e-mail server is located there.
Designed local area network solution for the company’s head office

The above figure shows the head office local area network where the various network devices
used are indicated, the network has a wireless router that is used to connect the network to the
internet services providers ,however there is another router that is used to connect the office
local area network to other office networks, the hub device in the network is used to connect the
departmental network sections to the LAN router, the switches are then used in the network to
interconnect the end network devices together and then to the network hub.
In this network the email server is connected in the general department where there is the IT
administrator and it is used to send the emails to the various offices, more over the office server
is the head office file server that stores and enables sharing of the stored files between the
various company’s offices.
Type of local area network wiring recommended
In the ARR head office network the network wiring require to be done in order to interconnect
the various network devices, therefore various wiring items will be required which includes the
following.
i. Registered Jack 45 (RJ45)
This is wiring item that is used to connect the untwisted pair cable to the end network devices
and the network sockets [3].
ii. Clipping tool.
This is the network wiring item that is used to clip together the RJ45 with the Ethernet cable to
enable them to be connected to the network sockets and end devices.
iii. Category 6 Ethernet cable
The cat6 cable is the most recommended wiring media that will be used to connect the network
devices and the end network devices ,however the cat 6 cables had been selected since they
supports high data transmission speed and will be efficient in the file transfer and sending of
emails between the office staffs [6].
Below are some of the reasons of selecting the cat 6 cable as the wiring media.
a. Provides high data transmission speed of 1000mbps at 250 MHz bandwidth.

b. It is a standardized type of cable to do the LAN connections.
c. It high reduces the power losses since it require little energy to transmit data.
d. It is easy to upgrade to higher media since it supports the gigabits speed.
e. It has the backwards compatibility since it can be connected to cat5 port and function
effectively.
f. It supports very fast networks performance and is able to even deliver the gigabits speeds.
Type of local area network topology and protocol recommended
In the ARR company head office local area network there are various services that are required
to be implemented and they will be using different network protocols, however the network
devices are connected to each using various topologies in the departmental level and in the entire
head office LAN as discussed below.
Topologies
In the head office there are two major topologies which include:
i. Star topology.
The star topology is used in the three departmental network sections where the network end
devices are connected together at one point using the network switch.
ii. Hybrid topology
After all the departments are connected in a star topology then the three departments star
topologies are linked together using a network hub device and as a result a hybrid network is
formed.
Protocols
In this head office local area network there are various services that are required which includes
the file sharing, sending e-mails and access to the internet services , therefore the below
protocols will be applied.
i. Internet message access protocol (IMAP).

This protocol will enable the office staffs clients computers to access the email from the network
web server conveniently.
ii. File transfer protocol.
This is a standardized network protocol that mainly transfers files stored in the departmental
servers to the staff’s client computers and this is enabled by the separated controls and data
connections between the client’s computers and servers [2].
iii. Internet protocol.
This is another protocol that is used in relaying of the network data packets across the network
sections however it has the routing functionality which enables the internetworking and
establishment of the internet services in the head office network.

Summary
In this report the ARR network design was done where various activities were
involved ,basically the ARR company network covers six offices networks which were located
in the Melbourne and the neighboring suburbs ,the report had covered the designing of the
company’s wide area network that covers the six offices , the designing of the head office local
area network , the drawing of the various floor plans in the head office network departments, the
identification of the network topologies and the protocols to be used in the head office to enable
the e-mail service, internet/intranet access services, and file sharing services and the
identification of the type of the wiring that is most appropriate for head office local area network.
The management proposed this network in order to enable the communication within and outside
the offices, sharing of files, and enabling the intranet and internet services access to all staffs,
therefore all those requirements will be achieved through the implementation of the proposed
network.
