You were selected to design a small peer-to-peer network for a new facility which has six computers and a networked printer. Each desk computer must have a wired network connection. The rooms are to have wireless access for mobile devices.
For this assignment, utilize the Gliffy software application to create a basic network diagram depicting a star topology with a switch as the central communications node. The focus here is on the network communications equipment for this LAN. Include only that equipment and end node devices on the network diagram. There is no need to draw out the layout of the physical space.
In addition to providing a network diagram, you must also provide a short essay that describes the details of the LAN equipment that is being used and the connections. In the essay, be sure to explain why each device is positioned where it is.
Also, briefly state any assumptions you’ve made about the kind of work being done, the demands the personnel in the office will put on the network, how they’ll use it, and how that influenced your design. For example, if the business that uses the LAN is a small video-based news streaming service, they will probably need more performance from both their network and ISP than a small rental property management office might need.

1. Depict a star topology that uses Ethernet.
2. Provide a ‘cloud’ shape or another symbol for the ISP WAN service. Label the symbol as ‘Dial-up,’ ‘Cable,’ or ‘Fiber Optic.’
3. Label all network devices in the LAN (brand and model names are acceptable but not required).
4. Connect to the ISP service using a dial-up modem, cable modem, or, if using fiber optic service, an optical network terminal (ONT). Do not use a combination device such as a modem/router.
5. Connect the LAN router (wireless router) to the ISP WAN service device. The LAN router provides many capabilities to include: DHCP, NAT translation, port forwarding, QoS, and software firewall services. Do not use a router/switch combination device, however a router with integrated wireless capabilities is acceptable.
6. Use a managed switch as a centrally-located device to provide wired network connectivity for the seven end nodes (six desktop computers and a printer). Connect the switch directly to the main LAN router.
7. Connect the seven end nodes directly to the central switch.
8. Label the specific type of physical media (cables) being used to connect the LAN router to the ISP service device, the central switch to the LAN router, and the seven end nodes to the central switch.
9. Use a screen capture tool such as Snagit or the Microsoft Clipping Tool to copy your diagram and paste the copied image into a Word document with the written essay.
Provide a separate network firewall hardware device in your diagram. Locate the firewall between the ISP WAN device and the LAN router.
To alleviate some of the workloads placed on the LAN router, you could disable the wireless functionality of the LAN router and provide a separate Wireless Access Point (WAP) to provide wireless network access for the mobile devices (cell phones, iPads, etc.).
Connecting the Wireless Access Point (WAP) directly to the primary router will enable isolation of the wireless LAN (WLAN).
