You Are Assigned A Project To Design the Computer Network For A New De

You are assigned a project to design the computer network for a new dental office in your neighborhood. The office will host the following equipment: five dental examination rooms each with a computer to access patient information, two offices for the two dentists who own the facility, each office with a laptop station, one reception area with a computer desk and printer, one shared printer for the dentist and office staff in a shared location, and one server computer to host the web software application to manage patient appointments, treatment history, and to process payments.

Required items include: project overview, computer hardware overview, printer overview, network design, IP address details, pricing information, and labor charges. As the network designer, you are required to design the computer network for the dental office, considering that the printers and the six computers in the examination rooms and reception area may not be Wi-Fi enabled. Use Packet Tracer to create a diagrammatic representation of the network design, network devices used, and the reasons behind selecting that network. Select specific market-branded devices and provide a pricing sheet for the network devices. Submit your diagram here.

Paper For Above instruction

The design of a reliable, secure, and efficient computer network for a new dental office necessitates careful planning of hardware components, network topology, IP configurations, and budget considerations. This paper delineates a comprehensive plan for establishing a wired local area network (LAN) tailored to the specific requirements of the dental practice, incorporating device selection, network topology, IP addressing, cost estimation, and implementation strategies.

Network Overview and Equipment Requirements

The dental office comprises multiple workstations, including five examination rooms each equipped with a computer, two private offices for dentists with laptops, a reception area with a desktop computer, a shared printer station accessible to staff and dentists, and a server designated for hosting web applications. The primary goal is to ensure seamless, secure, and high-speed connectivity between these devices while minimizing latency and ensuring data protection.

Hardware and Device Selection

For the wired LAN setup, high-quality network switches and routers are essential. Cisco is a reputable brand offering durable and reliable network devices. A Cisco 2960 Series switch provides sufficient ports for interconnected devices, with features supporting VLAN segmentation for security. The Cisco ISR 4000 Series router offers robust routing capabilities, support for VLANs, and firewall features essential for protecting sensitive patient data. The server, a Cisco UCS or Dell PowerEdge, hosts the application software, with redundant power supplies and sufficient processing capabilities.

For end-user devices, Dell OptiPlex desktop computers for examination rooms and reception ensure compatibility and longevity. Laptops for dentists, such as Lenovo ThinkPad series, offers portability with enterprise features. Printers, like the HP LaserJet series, provide high-volume printing with network connectivity options, possibly via Ethernet for reliability.

Network Design and Topology

The LAN adopts a star topology, centralizing connections through switches, which enhances performance and simplifies troubleshooting. The switch connects to the router, which manages outbound communication with the internet and manages internal routing. Each examination room computer, staff workstation, printer station, and the server connects via Ethernet cables to the switch, with wired connections prioritized due to the non-Wi-Fi enabled printers and the need for high data security.

Wireless connectivity is incorporated for laptops, enabling the dentists to work freely within the premises. An enterprise-grade Wi-Fi 6 access point (e.g., Cisco Catalyst 9115) ensures high bandwidth and low latency for wireless devices, with security features such as WPA3.

IP Addressing and Network Segmentation

The network employs a private IP address scheme, such as 192.168.1.0/24, with static IPs assigned to critical devices like servers and printers. VLANs segregate network traffic: VLAN 10 for examination rooms, VLAN 20 for staff and reception, VLAN 30 for administrative servers, and VLAN 40 for guest Wi-Fi, if provided. This segmentation enhances security and manages bandwidth effectively.

Cost Estimation and Pricing

The approximate cost for each network cable drop is $300, covering cabling and labor. Purchasing branded devices—Cisco switches (~$1,200), Cisco router (~$2,500), access points (~$900), desktop computers (~$800 each), laptops (~$1,200 each), and printers (~$400)—provides a reliable infrastructure. The server costs approximately $5,000, matching project scope and performance needs.

Labor charges will vary depending on the complexity, but estimated labor costs for installation, configuration, and testing amount to approximately $4,000.

Implementation and Justification

Implementing wired connections in critical areas ensures high-speed data transfer and security, meeting healthcare data confidentiality standards like HIPAA. Wireless access points provide flexibility for mobile devices without compromising network integrity. Using proven hardware and segmented network design aligns with best practices, ensuring scalability, security, and ease of maintenance.

Conclusion

The comprehensive network plan detailed herein addresses the operational needs of the dental office, balancing performance, security, and cost-efficiency. By adopting a star topology, employing robust market-branded devices, and segmenting the network with VLANs, the design ensures reliable service delivery and protection of sensitive patient information. Future scalability is considered through modular hardware choices and IPv4 addressing schemes, supporting the office's growth without extensive redesign.
