Milestone Two Network architecture forms the structural foundation of an organization's technological infrastructure, encompassing a diverse range of components, from hardware and software to communication protocols and connectivity options. In the context of SNHUEnergy Inc., this exploration presents a valuable opportunity to gain insights into their network architecture. By scrutinizing traffic patterns, we can uncover critical insights into the company's operational dynamics and provide recommendations for bolstering network capacity and security. Our aim is to create a comprehensive visual representation of the network's end-to-end path flow, accomplished by crafting a detailed Visio diagram that illustrates traffic flows and network elements. Physical Network Devices By reading the scenario, we can identify most of the infrastructure’s physical devices. SNHUEnergy Inc. uses network routers, switches, and a single firewall to direct and handle all the traffic both offices use. A WAN is used to connect the offices together and then the internet is provided through the Dallas Office. In addition to the network devices that are in use the company utilizes multiple applications and SQL Servers talking with multiple end points. Critical Traffic Patterns In the Traffic Flow WireShark Capture we can identify four different protocols being utilized. RTP is the most utilized in the traffic flow, so we need to keep that in mind moving forward with recommendations as we want to ensure reliability and not have bandwidth issues during real time traffic utilized for VOIP. VOIP also appears to be the only external communication that is made during the capture between 67.16.104.172 & 10.0.6.73. The second

most used protocol is MySQL which means access to the applications and servers that are available are typically heavily used. We can also note light TCP traffic and only one internal encrypted message between the devices 10.0.6.73 & 10.1.0.248. Patterns Across the infrastructure Currently, the network comprises a wide area network (WAN) that connects the Dallas office (housing human resources, accounting, and payroll) with the Memphis office (responsible for billing and operations). The company has plans to expand to two additional regional offices in Kansas City and Houston, making it essential to assess the existing traffic patterns and the future requirements. The primary communication pathways include TCP/IP traffic, which facilitates data, voice, and video applications across the organization. This traffic enables the exchange of information within the company's various departments and supports key critical applications such as human resources, email, and Voice over Internet Protocol (VoIP). As the organization expands, the traffic patterns will extend across the WAN, emphasizing the significance of TCP/IP communication processes in ensuring seamless connectivity between different offices and the efficient flow of information. Performance Issues: One of the primary concerns for SNHUEnergy Inc. in their network infrastructure is the potential for network congestion and scalability challenges. As the company experiences growth and adds new regional offices, there's a risk of network congestion, particularly on the existing WAN. The expanding user base and the increased volume of data, voice, and video traffic may lead to performance bottlenecks, which can hamper productivity. Furthermore, the reliability of the network infrastructure is paramount, as any downtime or hardware failures can result in significant disruptions to business operations, especially as the
