Project Plan
The present network architecture of SNHUEnegry Inc. has been assessed
so that its communication model can be expanded. The business undertaking is
a medium-sized oil and gas concern that has been performing decently. In order
to strengthen its presence, activities and performance, its communication model
must be enhanced. The project analysis plan for SNHUEnegry Inc. has been
presented so that the communication architecture can be improved.
Identification of the current network application
In the present times, SNHUEnegry Inc.’s main headquarters use Human
Resources (HR), emails, accounting and payroll as the network applications. The
Memphis office uses billing and operations as the network applications. Both of
these office locations even make the use of video conferencing services and
VoIP phone system in order to communicate in the business context. The
existing network application of SNHUEnegry Inc. plays a vital role as it offers
a wide range of services that enhance the level of connectivity such as the
high level of reliability, control over information flow and support relating to
control-oriented data streaming (SNHUEnergy, 2019). The role of the
transportation layer in the current network application of the business concern is
of paramount importance as it is responsible to deliver business data to the
concerned application processes that exist on the host computer systems (Probert
et al., 2018).
Labelling of the components with suitable OSI network layer
Each and every component of the network interface of SNHUEnegry Inc.
can be linked with a layer of the OSI network. The main components of the
network include the router, switches, firewalls, personal computers (PCs), servers,

applications and work stations. The appropriate OSI network layer for the switch
component includes data link (the second layer). The appropriate OSI network
layer for the router component is the network layer (the third layer). The role
of the network layer is of paramount importance as it would play a vital role
to manage the entire network and manage the flow of the packets
(SNHUEnergy, 2019). The firewall component can be labelled with the Transport
layer of the OSI network. It would play a major role to strengthen the mode
of communication between the devices that exist in the network. The suitable
OSI network layer for the Personal Computer component is the seventh layer.
Description of the components
Routers can be defined as the small electronic equipment that helps to
join a number of computer networks with one another by using wired or
wireless connectivity options. These devices have a processor known as CPU,
varying kinds of digital memory and input-output interfaces. It is a vital
networking device which is responsible to forward data packets between
computers.
Switches are primarily responsible to receive a set of information from a
source from a source that is connected to it. It is also responsible to dispatch
the same information to the specified destination. The network switch can be
termed as the main component that binds the entire computer communication
model. It maintains a list of devices that are connected to it.
The firewall can be defined as the gatekeeper that exists between a
‘private network’ and the rest of the components. It plays a vital role to
ascertain what is accessible in the private network from the external setting.

Firewalls can exist in various forms but their role is extremely critical to
conduct the critical examination of the network packets.
Network assessment
The poor quality of the connectivity that exists between the Dallas router
and the Memphis router adversely affects the entire business and the way in
which its established connection with its users. Due to the poor network
connectivity that exists in the current times, SNHUEnegry Inc.’s wealth-generating
capacity also gets adversely impacted. The various network applications that are
impacted in the process include the video conferencing, human resources,
accounting and payroll and email.
When the router of the business gets unresponsive, the users are forced
to wait for the speed so that they can resume the work relating to any file
transfer, application use or the download of attachments. As there is just a
single router in the Memphis office, the business is exposed to a significant
level of technical risk. The role of the firewall in the business context is of
prime importance as it helps to check the traffic on the network.
Summary – Project Requirement and Deliverables
In order to strengthen the communication approach of the business,
SNHUEnegry Inc. must use the Transmission Communication Protocol/ Internet
Protocol (TCP/IP). It would help the business to strengthen the quality of
connectivity between two regions. It could be included with the WAN
connectivity (WhatIs.com, 2019). The better quality of connectivity would mean
that the business would have an improved and more secure communication
network (WhatIs.com, 2019). The security aspect of the network must be
critically taken into consideration before connecting two different sites so that

the digital data and the overall communication model could be safeguarded
thoroughly.
