Throughout the course you will be working with improvements to the Bedford Campus and its satellite campus in Mayberry. The Bedford Campus with its 12 full-time employees and two classrooms has recently increased its online enrollment to 1500 students working asynchronously. The increase in student population has had a significant slowdown in the network connectivity in the classroom. Reports have stated that it can take up to twenty minutes, sometimes longer, to get connected to the online classroom or to get to the Internet. You have been tasked with determining the root cause of this problem. The analysis should begin by taking a holistic view of the to understand the topology. Then, progress through the OSI model to find the problem. Also, look for potential choke points that could cause a significant network slowdown. After locating the potential cause of the problem, a network with a proposed solution. a 1-page network diagram using Microsoft® Visio® of improvements that could be made to the current configuration, including wireless improvements to the network. Assumptions can be made in order to complete the diagram. The finished diagram should include the following:

The task at hand is to determine the root cause of the network connectivity issues at the Bedford Campus and propose improvements to the current configuration. To begin the analysis, it is necessary to take a holistic view of the topology of the campus network and then progress through the layers of the OSI model to identify potential choke points and find the problem.

The Bedford Campus, with its 12 full-time employees and two classrooms, has recently experienced an increase in online enrollment to 1500 students who work asynchronously. This influx of students has resulted in a significant slowdown in the network connectivity within the classrooms, with reports indicating that it can take up to twenty minutes or longer to get connected to the online classroom or to access the Internet. This delay negatively impacts the learning experience for the students and hinders the efficiency of the teachers.

In order to diagnose the root cause of this network slowdown, it is essential to examine the entire network infrastructure at the Bedford Campus. This includes the physical layout of the campus, the network devices in use, and the network protocols and services implemented.

Starting from the physical layer, potential issues could arise from faulty cabling, defective network devices, or inadequate network connectivity. It is important to ensure that all the cables are properly installed and terminated, and that they are in good condition. Additionally, the network devices, such as routers, switches, and access points, should be checked for any hardware malfunctions or misconfigurations.

Moving up to the data link layer, potential problems might be caused by issues with Ethernet switches and network interface cards (NICs). These components facilitate the transmission of data between devices on the same network segment and may contribute to network slowdown if they are not functioning optimally.

Further up the OSI model, at the network layer, potential choke points could be caused by routing issues or limitations in network bandwidth due to increased traffic. It is crucial to examine the routing tables and protocols being used, as well as the capacity of the network links, to identify any potential bottlenecks.

Finally, at the application layer, it is necessary to determine if there are any specific applications or services that are causing the network slowdown. For example, if a particular software application is consuming excessive network resources, it could be affecting the overall network performance.

Once the root cause of the network connectivity issues is identified, it is necessary to propose improvements to the current configuration. This includes suggesting changes to the network topology, as well as wireless improvements to enhance network connectivity. A network diagram using Microsoft® Visio® can be created to visualize these proposed improvements. Assumptions can be made in order to complete the diagram, but it is important to ensure that the proposed solutions align with the identified root cause.
