CSC00240: Data Communication and Networks - Network Design Report

This report details the network design for a biomedical software development company with a headquarters and three branches. The report begins with an introduction, followed by an organizational description outlining the company's structure and operations. A key component is the address allocation plan, covering both IPv4 and IPv6 subnetting schemes, detailing subnet names, sizes, allocated addresses, and ranges for each network segment. The report then presents logical and physical network diagrams to visualize the network's structure. Finally, the report concludes with a summary of the design and references used. The assignment covers the design of a network, including IP addressing, subnetting, and network diagrams, to meet the company's requirements.

Summary
The company that has been chosen for this scenario is a development company that works and
operates within the field of biomedical that has been designing and developing the various
applications needed by the organizations working in that field. This report will provide with a brief
introduction of what is the discussion all about along with a brief description of the organization that
has been working for the companies in and around the entire Gold Coast region. The network that
belongs to the company has been redesigned and presented in a logical as well as a physical view.
Along with this, the IP subnetting has been done in both of the IPv4 as well as the IPv6 mode for the
entire network belonging to the organization. In addition to this, in the network diagram each of the
branch along with the headquarter has been provided with the required number of devices as well
as the network devices for a better network coverage and connection for the entire organization.

1. Introduction
The report has the primary inclusion of a number of tasks for the organization to create a new
network design for the organization as well as to develop the IP addressing of the whole network
(Almetova, Shepelev and Shepelev 2016). The network diagram will include all the computers,
printers, servers, switches as well as the other required devices for the network including the
network devices such as the likes of server, router, and the other switches (Fogel et al. 2015). The
report will also aim at developing the IP addressing in terms of IPv4 and IPv6.
2. Organisational Description
The entire scenario is regarding a development company that designs and develops software for the
biomedical field in and around the entire Gold Coast region (Bai et al. 2016). The company has a
Headquarter, which is again connected to three branches named A, B and C. The Headquarter
consists of a main router that is connected to the internet. From this router, each of the router
present in the three branches of the organization receives the server connection to the network
(Beckett et al. 2017). In addition to this, each of the branch consists of specific computers for
working along with the required number of additional devices as well as the network devices for a
proper implementation of the entire network belonging to the organization.

4. Conclusions
This organization that has been mentioned within this scenario works in the field of biomedical for
the designing as well as developing of required software applications that is required for the other
organizations in and around the entire region of Gold Coast. The report has been addressed to
redesign the entire network of the organization that consists of a single headquarter along with
three different branches namely A, B and C. The report also consists of subnet addressing in IPv4 as
well as IPv6 mode along with a proper diagram for the entire network of the organization in the
logical as well as the physical view.
