The South Dakota Campus with its 45 full-time employees has recently increased its enrollment to 1500 students per night. 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. The campus is using a Cisco 3500 Router and the access point in each classroom is wired to a Cisco switch. Your team has been tasked to determine the root cause of this problem. The analysis should begin by taking a holistic view of the network diagram 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, design a network with the proposed solution. This is the overview of the team project in this class. a diagram in Microsoft Visio , Word, or PowerPoint based on the description provided above of the South Dakota network. Assumptions can be made in order to complete the diagram. The finished diagram should include the following:

The first step in analyzing and determining the root cause of the network connectivity issue in the South Dakota Campus is to obtain a holistic view of the network topology. This will allow us to understand the various components of the network and how they are connected.

Based on the description provided, we can assume that the network consists of a Cisco 3500 Router and multiple access points in each classroom, which are wired to a Cisco switch. To create an accurate network diagram, we can make some assumptions about the network setup.

First, we can assume that the Cisco 3500 Router is the central component of the network, connecting the campus to the external Internet. The router will have multiple Ethernet ports to connect to the various switches and access points.

Next, we can assume that there are multiple Cisco switches throughout the campus, with each switch connected to several access points in different classrooms. This allows for distribution of network connectivity to the classrooms.

To create the network diagram, we can use Microsoft Visio, Word, or PowerPoint, based on individual preferences and familiarity. The diagram should include the following components:

1. Cisco 3500 Router: This should be placed at the center of the diagram, as it is the central component connecting the campus to the Internet.

2. Cisco Switches: Multiple switches should be placed around the diagram, indicating their connection to the router and their distribution of connectivity to the access points in classrooms. The switches should be labeled appropriately to indicate their location or function.

3. Access Points: These should be placed in each classroom and connected to the switches. The access points should be labeled with their respective classroom numbers or names.

4. Ethernet Connections: The diagram should include lines or arrows to illustrate the connections between the router, switches, and access points. This will provide a clear visual representation of how the network is structured.

In addition to the network diagram, it is essential to analyze the network based on the OSI model to identify potential choke points or areas of concern. The OSI model consists of seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.

Starting from the Physical layer, we can conduct a thorough analysis of each layer to identify any issues or bottlenecks that may be causing the slowdown in network connectivity. Each layer should be assessed to ensure that it is functioning optimally and not impeding network performance.

Once the potential cause of the problem is located, a proposed solution can be designed and incorporated into the network diagram. This may include upgrading or replacing certain components, reconfiguring network settings, or implementing additional network infrastructure to alleviate the network slowdown.

Overall, the network diagram and analysis based on the OSI model will provide a comprehensive understanding of the South Dakota Campus network and enable the identification of the root cause of the network connectivity issue.
