Unit Learning Outcomes: LO3 Design efficient networked systems. LO4 Implement and diagnose networked systems. Assignment Brief and Guidance: Assignment scenario (cont.) The CEO Mr. Nguyen is happy with your first report and now he has asked you to analyse the specification from the institution, as given earlier. You need to design and implement the networking project within a given timeframe: Task 2 Design efficient networked systems: Prepare a written step-by-step plan of how you are going to design a Local Area Network including a blueprint of your LAN. Justify your choice of devices for your network design. Produce a test plan to evaluate this design for the requirements of bandwidth and cost constraints as per user specifications. Justify the security requirements and quality of services needed for selection of accessories. Suggest a maintenance schedule to support the networked system. Task 3 Implement test and diagnose networked systems: Implement a networked system based on your prepared design. Conduct verification with, e.g., Ping, extended ping, trace route, telnet, SSH, etc. Record the test results and analyse these against expected results. Investigate what functionalities would allow the system to support device growth and the addition of communication devices. Discuss the significance of upgrades and security requirements in your recommendations.

Figure 2: Physical design 1.3. The difference between logical and physical design Logical Design Physical Design A logical network design is focused on the way to construct your plant and business, as well as where you should position critical network distribution points and what devices and switches you should employ to link the plant. It can also cover how IP addresses, VLANs, and switch settings are handled. A physical design network focuses on physical devices, and the cabling that connects them serves as the network topology's mapping. The physical network's topology diagram must depict items such as workstations, servers, routers, and so on, with the cable connection serving as the border between them. Table 1: The difference between logical and physical design The major distinction between logical and physical design is that logical design aids in the definition of data items and their connections, including database IP structures. Physical design aids in the construction of specialized databases such as Fiber, ISDN, and Ethernet that meet the demands acquired during the process, similar to a Class A, B, or C addressing scheme.
2. The user requirements for general network design A local educational institution has hired the business to conduct a networking project. The following is a breakdown of the project's requirements:
The following are the people who make up this organization: 200 students, 15 instructors, 12 marketing and administrative personnel, 5 upper-level supervisors, including academic heads and program managers, and 3 computer network administrators.
- Resources: 50 computers for students, 35 computers for staff, and 3 printers are available in the lab.
- There are three storeys in the building, all computers and printers are on the ground floor, save for the IT guys, who have their own labs on the first and second floors, respectively. 3. Logical design of the network Figure 3: Logical design 4. Physical design of the network

1. Test Plan On the ground floor, floors 1 or 2 can ping to rooms of other floors and ping each other. And from computers in different rooms can ping these servers. - The 1st and 2 nd floors include student computer labs, from the machines in these 2 rooms can access DNS, DHCP, etc. Can also ping each other.
- All rooms can use the wireless network.
- The system is installed correctly and the network can be used. To improve the safety of the network system, it should support the installation of a firewall system. 2. The pros and cons of design based on user requirements The pros of design based on user requirements The cons of design based on user requirements The system is capable of meeting full fill of the requirements. There are still many limitations and features that have not been extended Detailed design, easy to track There is no backup line in the system. In the event that the system fails, it will be forced to shut down. The price is cheap because it only meets the requirements with basic equipment
Figure 6: The interface of the PC in the teacher’s room My PC obtained an IP address via DHCP, and my DHCP allocator is "Server-PT Mail Server," with the IP addresses 192.168.15.0 and 255.255.255.0 configured.
Figure 7: The interface of Printer in teacher room My printer has a static IP address, therefore I set up a PC-based IP address in the teacher's room. The IP address of my teacher's room is 192.168.15.1. So I created the printer IP address in order to run the script.
