NETWORK PLAN

You were selected to design a small peer-to-peer network for a new facility that has six computers and a networked printer. Each desk computer must have a wired network connection. The rooms should have wireless access for mobile devices.

For this assignment, you will utilize Gliffy,

Links to an external site. a 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 LAN equipment that is being used and their connections. In the essay, be sure to explain why each device is positioned where it is. While this is the focus of the response, be sure to also briefly state how the work of the users in the office 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.

Gliffy is the diagramming software you will utilize for this activity.

REQUIRMENTS

• Depict a star topology that uses Ethernet.
• Provide a ‘cloud’ shape or another symbol for the ISP WAN service. Label the symbol as ‘DSL,’ ‘Cable,’ or ‘Fiber Optic.’
• Connect to the ISP service using a DSL 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.
• Connect the LAN router (wireless router) to the ISP WAN service device. The LAN router provides many capabilities to include: DHCP (Networking Computing),

• 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.
• Label all network devices in the LAN (brand and model names are acceptable but not required).
• Connect the seven end nodes directly to the central switch.
• Label the specific type of physical media (cables) being used to connect the seven end nodes to the central switch, the central switch to the LAN router, and the LAN router to the ISP service device. Also, label the type of cable used to connect the ISP device to the ISP WAN.
• Use a screen capture tool such as Snagit

Snipping Tool

1. Links to an external site. to copy your diagram and paste the copied image into a Word document below the written essay. When you do, be sure to copy so that the diagram and labels are readable, i.e., not too small.

Optional:

• 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 (e.g., cell phones, iPads, etc.).
  • Connecting the Wireless Access Point (WAP) directly to the primary router will enable isolation of the wireless LAN (WLAN).

Your application response is expected to be original. 

• In a document, compose an essay consisting of three paragraphs (250-300 words). This assignment must be in essay format with an introductory paragraph, body, and conclusion.
