Introduction
The previous report described the theory and definition of the devices that will be designed in
each lab. The company was very pleased with the previous report, so this report will discuss the
institution's specification analysis. The system will be completely designed with all equipment
between floors and will be completely connected to each other, according to the given topic.
Furthermore, the report will be presented more clearly on the physical and logical design,
providing a clear understanding of the IP table. Test the system, then report and analyze the
results. Determine the system's strengths and weaknesses. And will pay closer attention to the
system's flaws. Let us also look into this report.
TASK 1 - PROVIDE A LOGICAL/PHYSICAL DESIGN OF THE NETWORKED
SYSTEM WITH A 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 flows across the network, IP addresses,
admin domains, domain routing, control points, and so on. A physical network diagram should
depict the network topology exactly as it is: with all of the devices and their connections.
The physical signaling medium of a network (typically a LAN) consists of devices, locations, and
cables.

2. DISCUSS AND EXPLAIN THE USER REQUIREMENTS FOR GENERAL NETWORK DESIGN.
User Requirement (The report is tasked with the following):
I am employed as a network engineer by Nguyen Networking Limited, a high-tech networking
solution development company, which has branches in Ho Chi Minh City, Hanoi, Da Nang, and
Can Tho. The company has been contracted to implement a networking project from a local
educational institute. The specification of the project is given below:
+ People: 200 students, 15 teachers, 12 marketing and administration staff, 5 higher
managers including the academic heads and the program managers, and 3 computer
network administrators.
+ Resources: 50 student lab computers, 35 staff computers, and 3 printers.
+ Building: 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.
Explain requirements:
- In accordance with the article's request, I'll outline the specifications and general network
design as follows:
+ + I will use two routers, three switches, 50 student lab PCs, 35 staff computers, and four
printers in accordance with the assignment's criteria. Because there are more than 24
computers on each floor of my three stories, I have to use three switches totaling 48 ports.
- I will use 1 router, 2 switches, and divided it into 4 rooms instead of a 48 port switch
because I asked for all the computers and printers to be on the ground floor:
+ 15 PCs and printer 1 in the teacher's room (Teacher often prints questions for students,
so I will order a printer to print them easily)
+ Marketing staff room: 12 computers.
+ Managers room: 5 computers and printer 2. (The management room often has official
documents, or changes need to be printed, so I will order a printer, which is very
convenient.
+ Three PCs, a printer, and a network administrator. 3. (The admin room will have to
summarize the management process, or alter something, the printer is extremely
required, so I will offer a printer here) (The admin room will have to summarize the
management process, or change something, the printer is very necessary, so I will provide
a printer here.)
- The first and second floors are for students, so I'll share one router there in order to save
money and use two to link two rooms (I'm using two routers on port 48 because each
room is larger than 24 and I can't use a switch to connect).
- As my network is set up in a single building, I will divide each room into 25 labs and utilize
copper straight-through to connect PCs, printers, and servers. Additionally, link two
routers using Serial DCE
3. Provide a logical design of the network based on the specific requirements of the user. - The logic design I presented above is as follows: Figure 3 :Logical Design
- Supply the address table for the network devices incorporated in the above design. Table 1 :Addressing Table TASK 2 - EVALUATE THE DESIGN TO MEET THE REQUIREMENTS (P6) Table 2 :Test Plans
- Evaluate your network design:
- Pros:
+ My report satisfies all of the company's standards. In addition, the floors in my design
are distinct from one another. Four modest rooms have been created from the
bottom level (Admin, Manager, Teacher, and Marketing). I have divided 3 prints into
3 rooms so that I can simply print documents and 11.1 reports (Teacher, Manager,
and Admin). I also divided the amount of labs into 2 floors for the first and second
floors. With 25 labs on each floor.
+ Additionally, in order to maintain high data traffic and Internet speed and prevent
dozens of delays when students take examinations for unfortunate reasons, I
additionally utilize 2 router and 4 switches.
+ With regard to PCs, sharing a pass makes it simple to send papers and lend a hand to
one another. functions as a closed array.
+ By employing a single router to transport traffic for two floors of student labs, I was
able to spend less money on equipment.
+ I've secured two routers, stopped theft, and freely altered router configuration.
+ Even while it reduces expenses somewhat, the price of these gadgets is significant, not to
mention that the long cable transmission raises costs.
+ There is no wifi network across floors, which is a drawback if faculty, staff, managers, or
administrators bring laptops or smartphones to work.
- For this design network to work effectively, can you have any advice or solutions?
- If the business has the resources, I advise adding more routers to the network because
the increased transmission speed will prevent network congestion.
- There should be backup equipment, resilience, and high availability because the failure of
one router will have an impact on everyone on Earth.
- Devices must be very secure from the beginning to the end. Intrusion detection systems
must also be improved.
- Use technology sensibly and stay out of needless situations. costs associated with
resources, cost growth, and management challenges during installation.
- Router 2 Figure 6 :Configure Router 2
- Step2: Set IP Address for each router
I configure zip, enter IP for the router, and use static IP.
