INTRODUCTION
In today's modernised world, Technology have transformed the human creative world
into the automatised world. IT infrastructure within the industry one of the important aspect
nowadays, which helps in improving the productivity and efficiency of the business. This report
will be based on the networking infrastructure of the Xero company which is going to develop its
new branch within Sydney. This report will assist the organization in developing a effective IT
infrastructure for the company in order to improve the overall performance. This study will
provide logical design of the networking infrastructure within the Xero company which is newly
established in Australia.
Furthermore, it will create a complete knowledge about the service provider which fulfils
various data manipulation requirements of the users. This document also helps in determining the
geographical range of network design which supports the communication and interaction within
the systems situated within 8 floor building. Moreover, It will also help in identifying the IP
addresses and subnet masking in order to configure the systems within the industry. Various
virtualisation techniques are also identified here along with the dynamic scaling which is
supported by cloud computing.
MAIN BODY
1. Geographical scope of the network developed within Xero company established in Sydney
Geographical scope of networking can be termed as a range within which the computer
systems can interact with each other in order to meet the specific goal of the Xero company
Sydney branch. The scope of the network is referred to its geographical size. A network can
range in size from just a few computers to the thousands of computers linked together for the
main purpose of interconnectivity (Dijkhuizen Ham,2018). Networking is generally classified
under different types of categories such as LAN, MAN, CAN, WAN etc.
Sydney branch of the Xero company wants to establish a interconnectivity between 240
computer systems which are placed in the building of 8 floor. In order to connect the computer
devices with each other which can be further connected to the main server which controls all the
information of the company. Sydney branch of Xero organization uses mix architecture that is
LAN (Local area Network) and CAN (Campus area network) for providing the interconnectivity
within the 8 floored building. According to the given diagram, the network is divided into four
Local Area Network which connects the compute systems of the Two floors together in order to

create LAN network. All the LANs are then connected to a common server which establishes the
CAN (Campus Area Network).
In addition to this, network segment is a portion of the a computer network that is
separated from the rest of the network by various devices such as repeater, hub, bridge, switches
and router. Each segment generally consists of the multiple computers or other hosts and the type
of the segmentation is generally differs according to the type of the devices used. There are
commonly four servers used in this networking diagram.
2. Logical design for the Sydney branch which is based on three layered architecture. Also
identify the network devices and server used in development of the networking
infrastructure
The IT manager in Sydney Xero company wants to develop a architecture effective and
efficient architecture which allows the employees of the firm to easily access the information and
share the data within the enterprise. So Three layered hierarchical model will be used in order to
reduce the complexity of the networking design. Such layers are described as:
Core layer: This is the backbone layer which provides the optimal; transport of the data and
information between different sites (Sourek,and Zelezny 2019). It is referred as a high speed
switching backbone and this is mainly designed to switch the packets as fast as possible. This
layer is not involved in any kind of packet manipulation such as access lists and filtering.
