IT 640 Milestone Two Guidelines and Rubric Current Network Architecture Overview: Network architecture refers to the layout of the network, consisting of the hardware, software, connectivity, communication protocols, and mode of transmission such as wired or wireless. For the second milestone, you will provide a high-level overview of the SNHUEnergy Inc. network architecture. 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 as well as a security viewpoint. Finally, you will develop a visual representation of an end-to-end path flow of the existing network by creating a Visio diagram showing the output of the traffic flows. Prompt: In this section, you will analyze the information provided on SNHUEnergy Inc. in the Final Project Scenario document to provide a high-level assumption for the design of the network. To complete this assignment, you must address the following critical elements:       Based on what you know from the scenario, explain the types of physical network devices used in connecting all devices across the organization. Identify the critical traffic patterns currently used by the organization, supported by examples. Use the Traffic Flow Wireshark Capture document to guide your response. o Service (Voice over Internet Protocol [VoIP]) o Application (Structured Query Language [SQL]) o Network management o Other opportunities not specified above Describe the traffic patterns that the organization’s critical applications take across the infrastructure from office to office. Remember, the organization’s critical applications were specified in the scenario. Describe the potential performance issues that may occur within the current network if no changes are made to support the organization’s expansion. Provide examples to support your response. Describe the potential security issues that may occur within the current network if no changes are made to support the organization’s expansion. Provide examples to support your response. Develop a visual representation of an end-to-end path flow of the existing network by creating a Visio diagram showing the output of the traffic flows. Use the provided Logical Network Design Example file as a guide for creating your diagram, and include your diagram with your submission. Rubric Guidelines for Submission: Review each critical element and designate a bold subheading for each element followed by your review of the current network architecture. Include an introduction for this assignment that aligns with your analysis from the first milestone. Make sure your submission aligns with the current APA standards. Upload your Visio diagram as a separate file to complete this milestone.

As a consultant for the company, you will evaluate the current network architecture, determine any key changes that should occur, and recommend a highlevel 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.
