Introduction
The report deals with the case study of speedfix.co.uk, as they require implementing a
network after the evaluation of their present scenario of business and then separating every
departments of the company by implementing more than one Virtual LANs. An evaluation
about the various models of networks can be implemented and the various technologies that
can be used in order to configure the network for the Company. The company consists of the
four departments namely Finance/HR, sales, Admins and engineers. The network of the
company includes mainly four servers, dns, web, email and a file server those are common to
all. All the servers are shared between all the users of the network. The admin of the
company has decided to permit the staffs of the company to utilise the wireless networks by
using their own devices those are wireless such their mobile phones in order to access the
internet. The report deals with the knowledge and understanding of the network technologies
and the protocols those are required for the company, the design, and the implementation of
those technologies
Knowledge and Understanding
The business operation of the company need to be evaluated in order to identify the
requirements of the network. In order to simulate the network Cisco packet tracer 7.2 is
utilised and a model of the network is developed following the configuration of the VLAN
(Hameed and Mian 2016). For every division, separate switches are to be implemented and at
the center a device of layer 3 is utilised that is the switch of Cisco 3560 and the switch is
configured as the server of VTP and it is implemented in this way so that the information of
VLAN can be easily shared with the switch of the client. In order to improve the network, a
model of three layers hierarchical is chosen and the tools of the networks are implemented in
the network. The devices those are at the layer 2 are installed in the network of access

(Hameed and Wasim 2019). The WAN and LAN is designed by following the principles of
design. The LAN is bounded to only 10 km and if it is extended it can cause loss of packets.
A plan in order to allocate the address of IP is developed where the number of hosts and the
other devices those are required to be installed in every department of the company. The
more than one LAN is combined in order to form the WAN and a pc of the admin is required
to be deployed with a monitoring tool of the network such that the network can be monitored
and the test of a network is required in order to execute the jobs of maintenance of the
network. The interface of the router is connected to the device of layer 3 and the
configuration of DHCP is done by following the plan of subnet so that the address of IP gets
auto allocated (Raza, Kulkarni and Sooriyabandara 2017). The configuration of the device of
network with the DHCP assists in maximizing the network scalability and it can be
constructed with the device that is at the central in order to implement the changes.
Application and Analysis
The network of the company is required to be constructed in order to connect the
devices of the IoT and monitor the environment of the rooms of the servers to maintain a best
environment (Wurm et al 2016). A private address of IP of 192.168.1680/24 is utilised for the
LAN and 10.10.10.0/24 is utilised for the network that is wireless. An illustration of the
network is developed with the description of evaluation and proper address of subnet is
developed for the construction of the network. A model of the network is proposed that will
assist in choosing the technology and the protocol and then create the network following the
requirements of the company (Park et al 2016). An evaluation is made on the requirement of
the security and applied to isolate the admittance of every department and the documentation
of testing is developed to configure and verify the configuration.
