Theoretical
Contribution
Our research contributes to the relevant literature in a
variety of ways. For starters, this study expands our
understanding of P2P devices and their functioning in a
given environment. This enabled us to build a suitable
network linking departments utilizing P2P devices and
associated equipment. Various gadgets will be employed
in our network to provide smooth and fast
communication. Network devices are generally used in
computer networks to transmit and receive data between
computers in a timely and secure manner. These
specialized devices chosen for installation in the network
will be used to execute their specific jobs extremely
well.

We opted wireless connectivity to handle the problem of
connecting many departments with the presence of a
lake in the middle. We recommended employing P2P
devices with the inclusion of protocols to ensure the
network has a consistent availability, efficiency, security,
and optimum connection across all buildings.
Except for the link between the HQ and R&D, which was
impeded by a lake, the connections from departments to
the HQ were mostly standard. Using the P2P network
rather than other technologies such as Ethernet cables or
wireless routers, we were able to address a wide range of
challenges. Ethernet cables would have been
prohibitively expensive and impractical due to their
maximum length of roughly 90 metres, which would not
have sufficed for this architecture. Furthermore,
employing wireless routers was not an option since the
bandwidth required by the various end devices in each
department would be insufficient. Furthermore, wireless
routers are not scalable and are only appropriate for small
LAN topologies. This naturally led us to choose a P2P
network.
Using this P2P network, we were able to build a
functional and efficient link between the HQ and R&D
despite the presence of a lake in the middle. In each
department, the network consisted of two CPE devices
(the factory uses four CPE devices) and one POE switch
(the factory uses two POE switches). Furthermore, the
headquarters housed a WLC capable of managing all
protocols, traffic flows, and network devices. All network
traffic will be directed to its destination via the WLC,
where the administrator may choose to encrypt it, split it
and send it to various networks, or filter it to prioritize it
based on the defined quality policies. The WLC at the HQ
may be used to configure every device on the network. An
alert mechanism on the WLC may be designed to notify
administrators of any security breaches or network device
failures.
PoE switches are used to connect end devices to the P2P
network, which has several advantages such as data and
power transmission through a regular Ethernet
connection, which removes the need for AC/DC power
sources and outlets to power PD equipment. Because you
don't require an electrician to provide electricity where
you wish to place your new PDs, the expenses of adding
or installing appropriate PD equipment are reduced.
Furthermore, PoE deployments that use managed PoE
switches allow you to remotely restart connected PoE
devices. This can be done manually, automatically, or on
a schedule. PoE switches include watchdog functionality
(Powered Device Manager [PDM]), which cuts power to
offline devices and then resupplies it, causing them to
reboot. This feature significantly reduces the downtime of
the linked devices.
Furthermore, a safe and optimum connection capable of
handling increased user traffic during peak hours was built
utilizing the protocols that were used in the network.
There was no need for complex connections to connect
the devices because this network was totally wireless. In
the sense that it could recover from a failure, the network
was reliable. Data replication, node failure detection, and
recovery were all dependability factors examined. P2P
devices are simple to replace and setup in the case of a
failure. This ensures that the network is always up and
running because the network engineer is not required to be
there to fix the faulty device.
Flexibility is a crucial factor in organizations that want to
link their departments. The liberty of peers in a point-to-
point network allows them to join and leave at their
discretion. In order to deal with the scale and dynamism,
