9-1 Final Project Submission: Network Analysis and Architecture Evaluation

I have done a terrible job at writing my milestone pages because I don’t understand and can’t wrap my head around this networking details my instructor wants. I’m attaching the final rubric for the final paper and would like to see how much you would charge to make an A on this and do it for me.

Please let me know.

IT 640 Final Project Guidelines and Rubric

Overview
Within an organization, the dependability of network infrastructures has become less of a want and more of a need. Without a fully developed communication
architecture around business growth, efficiencies, and competitive advantage, many companies will find themselves underperforming. Network connectivity
used to be considered a luxury for many businesses, but it has recently become a critical piece of an organization. The fundamental understanding of how
networks play such a big role in the success of a company has to be assessed from the basic approach of the advancement in Transmission Control
Protocol/Internet Protocol (TCP/IP) communication and the functionality of the Open Systems Interconnection (OSI) model.

Understanding how a network communicates is key to understanding how your corporate applications and services work within the business. Your
understanding around the concepts of IP communication, devices used to communicate, and the traffic that is continually passed between devices is the first key
to gaining the understanding of network infrastructure. The knowledge you develop through this course will help build on your basic understanding of network
infrastructures and the components that are critical to the success of any business communication architecture.

For your final project, you will assume the role of a network consultant for an organization looking to expand its communication reach. You have been be tasked
with analyzing the current network architecture of the organization and determining any key changes that should occur as the organization prepares for future
growth. You will evaluate traffic patterns to determine critical aspects of your business and provide basic insight into what should be done to the network from a
capability aspect and from a security viewpoint as the organization prepares for future growth. Ultimately, you will recommend a design for the future network
architecture of the organization.

The project is divided into three milestones, which will be submitted at various points throughout the course to scaffold learning and ensure quality final
submissions. These milestones will be submitted in Modules Three, Five, and Seven. The final product will be submitted in Module Nine.

Before beginning your project, read the Final Project Scenario document about SNHUEnergy, Inc., an organization that is looking to expand its operations. Then,
review all of the logical and physical design diagrams as well as the Wireshark capture showing the traffic patterns of the organization’s current network. These
files are provided below:

 Milestone One Physical Diagram – Current

 Final Project Physical Diagram – Current

 Memphis Office Logical Design – Current

 Physical Network Design Example

 Logical Network Design Example

 Dallas Office Logical Design – Current

 Traffic Flow Wireshark Capture

your business and provide basic insight into what should be done to the network from a capability aspect and from a security viewpoint as the organization
prepares for future growth. Ultimately, you will recommend a design for the future network architecture of the organization.

Prompt: Your first milestone for this project will be the creation of a project analysis plan. Your plan will identify the network applications of the current network
including a description of how the current network is designed by explaining how the different layers of the Open Systems Interconnection (OSI) model relate to
each other within the network.

IT 640 Final Project Scenario

Imagine that you are a newly hired network consultant for SNHUEnergy Inc., a quickly growing oil and
gas company that has decided to expand its operation and begin developing a more efficient approach
to its use of the currently available technology. As a consultant for the company, you will evaluate the
current network architecture, determine any key changes that should occur, and recommend a high-
level design for future growth. The leadership team within the company has made a major commitment
to the board of directors that they will begin an initiative to create a communication architecture that
will allow the company to grow for the next ten years. You have been assigned the task of addressing
the overall framework for the architecture and evaluating the basic structure of the network, its
communication paths, and the type of traffic utilized. You will also begin to develop a basic security plan
in an effort to mitigate any risk the company currently has to internal and external factors.

SNHUEnergy Inc. is a medium-sized oil and gas company that is focused on the discovery and drilling of
oil-based products. It wants to grow from company solely focused on exploration into a company that
also provides the transportation and refinement of its discoveries. This is a big step for the company,
and it wants to make sure the communication infrastructure is ready to deliver in the next 12 to 18
months. The company is currently headquartered in Dallas, Texas, and operates small facilities in the
central United States. The total employee count is 120 across the organization, but this will grow by 50%
each year for the next two years. Initially, you will evaluate the current logical and physical design of the
network to determine the network connectivity, the traffic patterns of the organization, and what would
need to occur to enable the business to grow.

The network infrastructure consists of a single building with multiple floors and different divisions
(human resources, IT, accounting, and operations and payroll). The company will develop a plan to
expand to three additional regional offices in Kansas City and Houston. You will be asked to take the
initial design and determine what traffic will need to communicate at each office and which security
parameters will need to exist as the company grows. This work will consist of understanding the
connectivity and traffic traversing internally and externally and developing a plan to enable end-users to
access the correct communication to the key critical applications (i.e., human resources, email, and
Voice over Internet Protocol [VoIP]) across the company.

The infrastructure consists of network routers, switches, and firewall equipment that currently connect
all the users to the internet internally and externally. All the connectivity between the users is
Transmission Control Protocol/Internet Protocol (TCP/IP) traffic, which is utilized by data, voice, and
video applications across the organization.

In the future, the company will extend these services across the wide area network (WAN) by using
TCP/IP communication processes.
