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, managers and IT, so I decided to use switches with 24 ports, room for salesmans and managers, and room for it and the employees I installed a router in case some guests come over and use their equipment Also, I set up 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 to 22, I created a VLAN customer to help the customer's lab ping the other labs on the second floor The remaining 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 Figure 3: Logical design Provide a physical design of this network based on the specific requirements of the user Figure 4:Physical design The address table of the network devices used in the design above Device Interface IP R1 Fa0/0 Serial2/0 Fa0/0 Fa1/0 Fa6/0 Serial2/0 NIC NIC NIC NIC 192.168.10.1 10.0.1.1 192.168.20.1 192.168.60.3 192.168.30.2 10.0.1.2 192.168.30.1 192.168.60.30 192.168.10.2 192.168.20.2 R2 DNS HTTP DHCP1 DHCP2 Default Gateway 192.168.20.1 192.168.40.3 192.168.10.1 192.168.20.1 Subnet mask DNS server 255.255.255.0 255.255.255.0 255.255.255.0 255.255.255.0 255.255.255.0 255.255.255.0 255.255.255.0 255.255.255.0 255.255.255.0 255.255.255.0 192.168.10.2 192.168.10.2 192.168.10.2 192.168.10.2 Ground Floor PC salesmans PC IT2 PC manager PC employees Printer salesmans Printer managers Printer employees DHCP DHCP DHCP F0 F0 F0 F0 PC customers PC IT1 DHCP DHCP PC customer1 PC customer2 DHCP DHCP 192.168.10.1 192.168.10.2 192.168.10.1 First Floor 192.168.10.2 192.168.10.2 192.168.10.2 Second Floor C Task - Evaluate the design to meet the requirements (P6) Test plan: Activity Ping salesmans PCs to Printer salesmans Expected Reason Successful Same
