Introduction

After completing the first project, CEO Nguyen was very satisfied with my project and continued to assign me the second task. My task this time is to analyze the specification

• Ground floor: 3 computers network administrators, 15 computers teacher, 5 computers manager, 11 computer marketing, 3 printers and a computer administration
• First floor: 25 computers lab
• Second floor: 25 computers lab A logical design of the network based on the specific requirements of the user
• 25 lab computers in first floor are connected to the S3 switch
• 25 lab computers in second floor are connected to the S4 switch
• Network room and teacher room are connected to the S1 switch
• Staff room and management room are connected to the S2 switch

The physical design of this network is based on the specific requirements of the user The address table of the network devices used in your design above Devices Interface Ipv4 address Subnet Mask Default Gateway PC Lab1- 25 (Second floor) (^) Fa0/0 172.40.0.0 255.255.0.0 192.168.2.

Cost of devices 3 Routers, 3 Switches, 85 PCs, 3 Printers Location Location greatly influences the design Highly qualified staffs Because the technology is new, the company has to hire highly qualified workers and it can increase the total cost of ownership Infrastructure Equipment It may affect bandwidth speed Staff training Because staff are inexperienced with new technology, it will lead to longer downtime Time Time frame plays a part in completion of the project

2.3 A test plan for the design

Number Test object Result 1 DHCP address of Student PCs on first floor DHCP assign IP address automatically 2 DHCP address of Student PCs on second floor DHCP assign IP address automatically 3 DHCP address of Staff PCs and printers on ground floor DHCP assign IP address automatically 4 Ping between any PC Successful 5 Check the physical connection Green light in all connected device Evaluate my network design

• Bandwidth utilization: I use 3 routers and 4 switches, that will help improve the bandwidth compared to using 1 switch for the whole company.
• Security: I use Network Address Translation to protect the network
• Network flexibility and complexity: Routers, switches and all computers are directly connected. The design is simple. On the 1st and 2nd floors, each floor has only Lab computers. On the ground floor, it can be divided into many rooms for the staff according to their specialties and positions in the institute. Advantages:
• The design has met the requirements of the manager
• In a single location users can easily manage the entire network
• Since there is no possibility of data collision, it has high performance, which greatly affects data transmission between devices
• If one cable or device fails, all other cables or devices will continue to function normally Disadvantages
• No wireless network support
• No firewall and security system
• Network bandwidth shortage is easy to happen if all rooms are operating at full capacity at the same time
• If the central switch fails, the rest of the network cannot function. Therefore, it will be inconvenient to turn off the entire network if you want to maintain and upgrade the central switch

User requirement basic system maintenance schedule

I set ip address for each computer in the network room and teacher room to connect to S I do the same with the management room and the marketing room to connect to S

Finally, I try to send the file through the computers

Ping Case How to test Test result Compare 1 Ping from Lab PC1-Lab to PC25-Lab Enable Pass 2 Ping from Lab PC1-Lab to PC26-Lab Enable Pass 3 Ping from Lab PC1-Manager to PC5Manager Enable Pass 4 Ping from Lab PC1 to Enable Pass 5 Ping from Lab PC25-Lab to one of the devices connected to the S Enable Pass 6 Ping from Lab PC1 to one of the devices connected to the S Enable Pass 7 Ping devices connected to S together Enable Pass

Task 4 - Document and analyze test results

against expected results (P8)

4.1 Write down the above implementation process into the

logbook

Number Work to do Noter 1 Check the DHCP on ground floor, first floor and second floor From PC check the DHCP in IP configuration 2 Check the physical connection Check the cable 3 Check the establish between PC from ground floor Ping between PC 5 Check the establish between PC from first floor Ping between PC 6 Check the establish between PC from second floor Ping between PC

4.2 Test results, based on the test plan done above

Ping from Networking 1 to PC50-Lab
