1. Introduction After getting approval from CEO Nguyen, in this Assignment, I will present about the bearing system I designed, the advantages and disadvantages of the design. System test plan and test results. Recommendations for future network upgrades. My report is divided into 4-chapter as follows: - Chapter 1: Provide a logical/physical design of the networked system with clear explanation and addressing table - Chapter 2: Evaluate the design to meet the requirements - Chapter 3: Implement a networked system based on a prepared design - Chapter 4: Test Result 2. Chapter 1: Provide a logical/physical design of the networked system with clear explanation and addressing table
2.1 The difference between logical and physical design
A physical design network focuses on physical devices and the cabling between them is the mapping of the network topology. The topology diagram in the physical network must show elements such as workstations, servers, routers... where the cable connection will be the boundary between them. Figure 1 - Physical Design
- Cost Depending on the funding that the user requires, the network devices in the system need to fully meet the user's needs and be able to expand the system. Network designers also need to have actual surveys to determine the density of network devices in the system.
- Security Security is always an extremely important issue in any network. To protect the underlying network infrastructure against unauthorized access, theft, or destruction of data, it is necessary to maintain monitoring of all systems and networks. Analyze activity logs for anomalies. In addition, building an anti- malware system in the organization's network is also an important thing in security.
- Management capabilities The network system can only be operated effectively if it is well managed. The management ability should ensure the following contents: o Fault Management : The ability to detect errors occurring on the network o Configuration Management : the ability to manage the configuration of the device. This management capability includes configuration file management, device statistics, and software management as well as configuration changes. o Administration capability : the ability to manage, test, and control the overall system from an intermediary perspective. o Performance Management : Ability to collect information from the device, transmission line, display the device's usage status o Security Management : Ability to manage, set up, and monitor anomalies in the network
2.3 Design the network system for the situation
People: 200 students, 15 teachers, 12 marketing and administration staff, 5 higher managers including the academic heads and the programmer managers, and 3 computer network administrators. Devices: 50 student lab computers, 35 staff computers, and 3 printers. Infrastructure: 3 floors, all computers and printers are on the ground floor apart from the IT labs – one lab located on the first floor and another located on the second floor
2.4 Physical design based on user requirement

3. Chapter 2: Evaluate the design to meet the requirements
3.1 Test Plan
- In the first layer, devices can ping each other and devices of other layers
- 2 rd and 3rd floors include student computer room and wireless router Devices can ping each other and other floors
3.2 Evaluate your network design
The network structure of each layer is star topology because it is quite simple with the stability of technical control, the network can be narrowed or expanded depending on the purpose of use. Or moreover, with this model, the system works according to the original connection song, if there is a device at the information node that is faulty, the network will still work normally. The model has the fastest speed, when there is a network failure to check and repair. Advantages:
- Ping over different networks is fine
- Labs’ students that use a wireless connection to connect to other devices
- High security because there is a password in the router Disadvantages:
- Internet connection speed will depend on service provider, there is no backup measure in case of problems from service Provider.
- It is very easy to have a network bandwidth shortage if all rooms are operating at full capacity a Some of the solutions:
- Adding more switches can also reduce congestion and free up bandwidth for other things.
- Add support servers to use and search.
- Upgrading the security system
3.3 Install and configure network services and applications
I decided to use the DHCP protocol because DHCP will help to quickly, automatically and centrally manage the distribution of IP addresses within a network. Advantages of DHCP:
- DHCP has a function that allows automatic configuration
- Network connection speed of devices is faster
- Scientific IP address management, avoiding IP duplication and more stable network operation
- IP addresses, TCP/IP parameters are easily managed through stations 4. Chapter 3: Implement a networked system based on a prepared design In the design part, I will configure routers R1, R2 and R3. The commands are installed the same, but there will be a difference from the IP Address on each router.
4.1 Router Configuration
Step 1 : Erase and Reload the Routers
Figure 6 - Enter privileged EXEC mode and global configuration mode Step 3 : Set Hostname and disable DNS lookup On Router 2: Router(config) #hostname R 2 On Router 3: Router(config) #hostname R 3
Figure 7 - Set Hostname and disable DNS lookup
Step 5 : Configure the console password on the router Figure 9 - Configure the console password on the router
Step 6 : Configure the password for the virtual terminal lines Figure 10 - Configure the password for the virtual terminal lines Step 7 : Configure the Fast Ethernet interface and Serial
Figure 12 - Enable OSPF Step 9 - > Step 1 6 : Configure DHCP
