The major topic presented and described is the customer's network design needs. It's a system for a local educational institution that includes 50 lab computers, 35 staff PCs, and three printers, all of which have dynamic IP addresses. A logical design, as well as a physical design and an IP address table, will be delivered in response to that request. Following the creation of a test plan and the evaluation of this network system, a solution to solve the limitations will be provided.
The network design process, as well as the overall device results table, will be shown. Finally, provide the testing findings and compare them to the customer's initial request. Task 1 - Provide a logical/physical design of the 6.1 networked system with clear explanation and addressing table (P5): 1. Explain the difference between logical and physical design.
- What is the difference between logical and physical network diagrams? Logical network diagrams are concerned with how traffic moves throughout the network, IP addresses, admin domains, domain routing, control points, and so on. A physical network diagram should depict the network architecture precisely as it is: with all of the devices and their connections. The physical signaling medium of a network (often a LAN) consists of devices, locations, and cables. Figure 1: Physical Topology Logical network topology: refers to the manner in which data moves via a network between devices (computers, phones, etc.); it is independent of the physical connection.
The data channel in the circuit travels logistically. Figure 2:Logical Topology - What is the difference between a logical connection and a physical connection? A logical network arrangement is the communication strategy that connects two networked computers. A logical arrangement is the flow of data between two systems. In reality, the network connection is defined by the network's logical design.
The physical arrangement is configured using logical scheduling. Logical networking may be improved and utilized to link two or more machines. The virtual network design is logical, while the physical network design specifies the operation of the network hardware. Physical designs govern the flow of data or communication between two networks, whereas logical designs control the flow of data or communication between two computers connected by a cable.
Discuss and explain the user requirements for general network design. User needs (as stated in the report): As we can see, I have designed the requirements with three floors: the ground floor, first floor, and second floor. For specifically, I will introduce each floor below: Ground Floor: There will be 33 people on the first floor, including 15 salesmans, 12 employees, 5 managers and IT, so I decided to use 2 switches with 24 ports, 1 room for salesmans and managers, and 1 room for it and the employees. I installed a router in case some guests come over and use their equipment.
Also, I set up 3 printers so that salesmans, employee and managers can easily use them, and they are on the same VLAN as the PCs. The bottom VLAN It can ping the It room on the first floor. First floor: On the first floor, I designed an IT laboratory, a laboratory where customers learn about computers, and a waiting room that already has routers for guests. I have 20 PCs set up for customers in a customer lab.
So I chose the underlying 24-port switch. From ports 2 to 22, I created a VLAN customer to help the customer's lab ping the other labs on the second floor. The remaining 2 ports I created VLANs for it and the router. Second floor: Customer PC room, equipped with 31 PCs and routers, convenient for customers and IT to study and connect easily.
The customer VLAN helps the student labs and IT employees ping each other as well as the labs on the first floor. On the first level, I installed a router to link the network and a multiplayer switch. This switch is more powerful and efficient than others, and it can link three LAN networks. Provide a logical design of the network based on the specific requirements of the user.

So the expected results are successful.
Evaluate network design -Benefits: The network speed is rapid since all devices may connect to each other as soon as possible, ensuring that the connection is not isolated. Furthermore, the finish may now be easily applied or deleted. It is an excellent model since it is basic and has few flaws. If one device fails, the entire network is not affected.
- Drawback: No firewall. Because there is no integrated wireless network, mobile phones and laptops cannot connect. The prices of the gadgets have not been cut to the bare minimum. - Conclusion: Because my design is intended for 200 customers, 15 salesmans, 12 employees, 5 managers, and 3 IT administrators, it is conceivable that it will not be able to handle any extra employee or customers in the future.
To fast expand the network, I should choose a 36-port or 48-port switch.1 - Install and configure network services and applications on your choice (M3) Configure DHCP services Services—> DHCP—> DHCP1 Set up the default getway, start the IP address and DNS server, and save the settings. Also, keep in mind that the interface of the port to which DHCP connects is Fa0. Then, by turning on DHCP in each device, the linked devices automatically configure the IP address, default gateway, Subnet mark, and so forth. As may be seen, go to Manager PCs --> Desktop --> IP Configuration —> Enable DHCP.
The default gateway, DNS server, and IP address all begin with 192. Finally, I repeated the process with the other computer devices, printers, and DHCP 2. Task 3 - Implement a networked system based on a prepared design (P7) 1. Network Implementation Cisco Packet Tracer was used to implement the topology.
Before we can finish the setup, we must first accomplish the following: • Fundamental router setup (hostnames, password, IPs) • Configure DHCP • Create a Static Route with a Next-Hop Address and an Exit Interface. Consider the following network implementation: Example the network implementation: Figure 5: Router 1 Fa0/0 Figure 6: Router 1 S2/0 Figure 7: Router 2 Fa0/0 Figure 8: Router 2 fa1/0 Figure 9:Router 2 S2/0 Figure 10: Router 2 Fa6/0 Figure 11:DHCP1 IP address Figure 12: HTTP IP address Figure 13:DNS IP address Figure 14: DHCP2 IP address Figure 15: Salemans IP address Figure 16: Manager IP address Figure 17:IT2 IP address Figure 18: Customers IP address Figure 19:IT1 IP address Figure 20: IT IP address Figure 21: Customer1 IP address Figure 22:Customer2 IP address 2. Diagrams: Ground Floor: There will be 33 people on the first floor, including 15 salesmans, 12 employees, 5 managers and IT, so I decided to use 2 switches with 24 ports, 1 room for salesmans and managers, and 1 room for it and the employees. I installed a router in case some guests come over and use their equipment.
Also, I set up 3 printers so that salesmans, employee and managers can easily use them, and they are on the same VLAN as the PCs. The bottom VLAN It can ping the It room on the first floor. Figure 23: Ground floor First floor: On the first floor, I designed an IT laboratory, a laboratory where customers learn about computers, and a waiting room that already has routers for guests. I have 20 PCs set up for customers in a customer lab.
So I chose the underlying 24-port switch. From ports 2 to 22, I created a VLAN customer to help the customer's lab ping the other labs on the second floor. The remaining 2 ports I created VLANs for it and the router.
