NETWORK DESIGN 7 Network Design Student’s Name Institutional

The aim of the project is to design the appropriate computer network for a dental office within the neighborhood. The computer network design is set to meet the current and future IT needs of the two dentists owning the place, their staff, and their clients. This project recognizes that the stakeholders involved desire a robust, fast, reliable, flexible, and secure computer network at an affordable cost. The network design would ensure that there is access to shared resources like printers and servers. The design of the dentist office's computer network will ensure that there would be an efficient process of storing, retrieving, manipulating, and sharing of client information and other medical information.

Computer Hardware

The computer hardware present in the network includes a router, switch, two printers, 6 desktop computers, a server computer, and a wireless router.

Printer Overview

There are two printers in the facility. One of the printers is at the reception office and is not available for sharing. The other printer, however, is available for sharing. The shared printer is connected to the switch where other users in the network could request for it through the switch. The printer model is HP LaserJet Pro MFP M22fdw. Its print speed is 28 ppm and the paper capacity is up to 300 sheets.

Network Design

The network design follows a star physical topology. Every device on the network is connected to a central point, which is the switch. Each device is connected to the switch via CAT6 Ethernet cables. The two laptops are connected to the switch via a wireless router. The switch is then connected to the internet via an external router. A switch is ideal for this network design because it eliminates collisions. By eliminating collisions, the network becomes fast and efficient. The star physical topology also makes the network fault-tolerant, thereby reducing chances of the entire network shutting down if one device fails.

IP Addresses

The IP address used in the network design is IPv6. All the devices in the network, except the external router connecting the local area network to the internet, have private IP addresses ranging from 192.168.20.3 to192.168.20.30. Each device on the network has its unique IP address except for the unshared printer. The two laptops do not have static IP addresses as they are assigned randomly by the wireless router, which acts as the DHCP server. The IP address for the external router is 176.30.12.15.

Pricing Information

The printers cost $537.80, while all the desktop computers cost $300.00 each and the laptops $500.00 each. The total cost for the Ethernet cables amounted to $100.00. The cost of the router and the switch was $60.00 and $300.00 respectively. The labor costs totaled $1000.00.

Paper For Above Instructions

The development of a network for a dental office involves multiple aspects, from hardware and design to addressing and pricing. Understanding these components ensures that the network meets the needs of all stakeholders—dentists, staff, and clients. By using a star topology, we minimize the risk of total network failure and enhance performance.

### Importance of Network Design

Robust network design is crucial for any business, especially in a healthcare setting where patient information and efficient service delivery are paramount. Networks must support various operational needs, including efficient data storage, retrieval, manipulation, and sharing.

### Hardware Setup

The proposed network comprises essential components such as a router, switch, multiple computers, and printers. The design facilitates smooth communication between devices while ensuring scalability for future needs. This arrangement allows for easy maintenance and upgrades, fulfilling both current and anticipated IT needs.

The HP LaserJet Pro MFP M22fdw printer plays a pivotal role in the network by providing a reliable printing solution for the office. Its capacity and speed ensure that both dentists and their staff can manage their printing needs efficiently without causing bottlenecks in service.

### Network Topology and Functionality

The choice of a star topology aids in maintaining an organized and effective network. By connecting all devices to a central switch, the network ensures that even if one device fails, others remain unaffected. This architecture is essential for a dental office where uninterrupted service is necessary for patient care.

Each device connects through CAT6 cables, ensuring high-speed data transfer, while the inclusion of a wireless router allows for flexibility and mobility with laptops. This combination supports a dynamic work environment where staff members can move freely while staying connected.

### IP Addressing

Utilizing IPv6 for the network reflects a forward-thinking approach, accommodating a growing number of devices. Private IP ranges ensure that internal communication stays secure and efficient. The setup guarantees that all networked devices, including laptops, desktop computers, and the router, have their unique addresses, fostering effective communication.

The assignment of dynamic IP addresses to laptops enhances flexibility, particularly for staff members who may share devices or use different laptops. This management strategy reduces manual overhead while maintaining operational efficiency. The presence of a DHCP server simplifies the networking process, particularly in scenarios of device mobility.

### Cost Analysis

Cost considerations are a critical factor in the planning phase of any network design. The total expenditure for setting up this dental office’s network aligns with the size and scope of operations. Notably, investment in quality hardware translates to dependable operations, ultimately benefiting staff and clients through excellent service delivery.

Each component of the budget—from hardware to labor—reflects the need for quality and reliability. Investing in a reliable router and switch, for example, ensures that network-related downtime is minimized, thus supporting the efficiency of the dental practice.

### Conclusion

Designing a network for a dental office revolves around understanding the needs of the stakeholders and making choices that enhance operational efficiency while ensuring future scalability. By carefully considering hardware choices, network topology, IP addressing, and budget constraints, the network can be both effective in meeting current demands and flexible for future growth.
