1.0 Introduction
Networking is defined as the process of interconnecting set of computing devices that are used
for the purpose of communicating and much more sharing of information and resources on the
same platform (Brandley, 2017).during the network implementations many organizations may
opt to use different designs in designing their office or firm network. This report is proposal that
is implemented on the basis that the ITech is wishing to replace the network in existence with an
advanced and improved on that will satisfy all the needs of the company in terms of the
performance (Long, 2010).
1.0.1 Objectives of the Proposal
The main objectives of this proposal are highlighted as indicated here below.
 The main idea for ITech is considerations of future scalability of the network (Coleman,
2012).This network design to be created have to accommodate the need of additional of
equipment’s if need be arises in future in where we will have to do redesign the network
again from scratch.
 The other objective is how it will be easy in managing the network. The idea behind this
is that the design should be developed in a way that it will be easy to troubleshoot in
situations where problems are experienced.
 Last but not least is the network enhancing an environment that is more secure for the
operations of ITech on the way it renders it services to its customers and the adjacent
between the offices in the given buildings.
The idea behind this proposal is doing an analysis that is through the use of IT infrastructure
components, the need of why ITech is designing the network, the 3-layerered hierarchical
network design, dedicated server, Cloud-based design, and the simulation of the data center
using the proposed network design for ITech.
2.0 Background Info
ITech is a company that deals with computer hardware’s and software’s and have offices in
different buildings that are adjacent to each other and need to use the same network in
communicating and sharing information and resources. The company have more than 2000
workstations in all the buildings. The company also have a data center that help in data

monitoring in all the buildings. At the data center the company has mail servers, the web-servers,
domain name servers (DNS) and others. The domain name for ITech organization will be
“www.ITech.org.au”. The need for designing a new network in ITech is because the existing
network design is poorly and not efficient in terms of performance.
3.0 Components of IT Infrastructure
In the infrastructure of IT there are a lot of equipment’s that are used in facilitating the good
design of a network in many organisations in different ways. The following Components will be
used designing the Network of ITech Company.
3.0.1 ITech hardware components
Some of the networking hardware devices to be used by ITech are as described in the table
below.
Devices Functionality
1 cable This are the media transmissions that are used for connecting the devices in
networking over the network. In this case the Ethernet cable will be used in
connecting the backbones of the network and the ITech layers of the
designed network.
2 Router This is the device used in connecting the ITech local area networks from the
different adjacent buildings. Router provides the access to external
connections such as where we use the internet in situations of cloud-based
approach.
3 Switch For achievement of the scalability and the objectives, the switch will
enhance how flexible and scalable the network will be during configuration.
4 Servers The servers are used for enhancing the storage and sharing of the network
resources in ITech Company.
5 WAP
device
The wireless Access Point devices are used for broadcasting the WI-FI
signals across the ITech company where many users can access the network
using wireless connections.
6 Access These are the communicating devices that uses the network for

Devices communications and they may include things like Desktops (PCs), mobile
phones, IP phones and other many devices
3.0.2 Software Components
In software the platforms behind this components are such as the Operating systems (OS) this
may be like the NOS which is used by servers for management and accessibility of resources. In
this scenario of ITech the network design entirely will depend much on the described
components of IT Infrastructure for any organization to be successful on any design of the
network. For the hardware each and every component may have system software that manages it
and which helps in determination of the entire ITech network performance.
4.0 3-layer Hierarchical Model.
In understanding the 3-Layered hierarchical model is network design where there is break-down
of the network in 3 layers. In each and every layer they perform specific functions which
simplifies the design of the network and hence it makes it easy in scaling and managing the
network (CISCO, 2014). The 3 layers that form the hierarchical model are as explained in the
diagram below.
Figure 1 3-layered hierarchical model
1. Core layer- offers the connections
between the distribution layers to
other local area networks in ITech.
2. Distribution layer- connecting the
components of access layers by
enabling the connectivity of access
layer to services
3. Access Layer- offering provision
direct to the end-user who is
connected to the network.
