After completing the first project. CEO Nguyen was very satisfied with my project and continued to give me the second task. In this 2nd project I was asked to analyze the specification as outlined in the first project. So I need to design and perfect my system and show the details that have been used in the system. I hope this second project of mine will meet the requirements of CEO Nguyen so that I can be trusted and entrusted with more projects in the future.
1. Provide a logical/physical design of the networked system with
clear explanation and addressing table (P5):
1.1. The difference between logical and physical network design
a. What is a logical design?
- A logical network is one that appears to the user as a single, separate entity although it
might in fact be either an entity created from multiple networks or just a part of a large network, it’s defined by it’s IP addressing sheme.
- Logical design is how data connections work through the computer network and how devices interact. And the graphic includes nodes such as servers, routers and switching as shown in a physical network design. A logical network design concentratesmon how to design out your facility and company, admins can design numerous network logic diagrams, including maps for WAN, LAN, AWS, Cisco and other applications. These deagrams are exceedingly comprehensive or offer an overview of high standards.
- There are the main characteristics of logical design: o VLAN selection o Logical plant floor layout o Typical configurations based upon standards o Access and distribution layer switch types, models and ports o IP Address scheme and subnetting
Figure 2 : Physical design
c. Compare between logical and physical network design
- Familiar point: the two important domains in networking are the physical and logical topology. These two layouts are important in networking, the connectivity between two computers can be made easier using either of these two domains. Physical network topography is based on the physical hardware used for the connection.
- Different point:
Advantages Disadvantages Logical design o Troubleshooting : if service is between two IP addressed, a logical network diagram can be utilized to exclude a firewall problem quickly. o Firewalls : you can verify that your firewall rules remain accurate with logical network diagrams. o Capacity planning : although physical network charts are important to the planning of capacity, logical charts also aid. They enable you to map network expansion or change and understand what the impact will be. o Sharing network information : you can use a logical network diagram if you need to share information on the network, but you want to disguise physical information on the network. o Eliminate redundancies : logical network diagrams will clearly help you determine what isn’t redundant. o If any node goes down the whole network is failed in the ring topology because the connection is the break. o The new device cannot be added or removed from the network. Physical design o Compliance : can be critical for proving compliance with key regulations, such as PCI, that may require specific, secure architecture. o Network maintenance and management : admins can run device inventory, get a visual overview of their environment, see how their infrastructure operates under various loads. o Solving : when problems occur, admins need fast insight into what is causing the bottleneck. o Needs monitoring software. o Equipment costs are high. Table 1 : Compare between logical and physical network design
o Performance limitations : are network dependability, traffic performance, and computer speeds for host/client.
c. Assessing user requirements
Tobe loved and trusted by users, response times, throughput, and reliability are key components of application usability: o Response time is the time to complete or transmit the reply between a command or keystroke entered and the host system. Interactive internet services such as automated teller and point-of-sale machines include applications in which rapid reaction time is deemed vital. o Apart from end-to-end connections, applications with large-volumn traffic have a greater impact on the networking throughput. Normally, low response time requirements apply to high-performance applications, when reaction-time sensitive traffic is low, it can usually be programmed. o Reliability is always crucial, there are legitimate demands on certain applications that surpass conventional needs. Some examples are emergency/ police/military operations that suggest a high hardware and topological redundancy need. In establishing the relative relevance of reliability for your network, determining the cost of any outage is vital. 1.3. System design
a. Partner requirements
o People: 200 students, 15 teachers, 12 marketing and administration staff, 5 higher managers including the adcademic heads and the programme managers, and 3 computer network. o Resource: 50 student lab computers, 35 staff computer, and 3 printers. o 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.
b. Logical design of network based on the specific requirements

o Ground floor: there are 5 room include network admin room, admin & marketing room,
teacher room, printing room and manager room. Figure 4 : Ground floor
Network-Admin room: in this room will include 3-PC network: 2 desktop and 1 laptop.
Figure 7 : Teacher room design
Printing room: in this room only includes 3 printers
o WAP for all users in ground floor and use IP address is: 192.168. 10 .1/ o VLAN for 3 printer is: 192.168. 10 .6 9 - 72/ Figure 8 : Printing room design
Manager room: in this room includes 12 PC for academic heads and 1 printer
o WAP for all users in ground floor and use IP address is: 192.168. 10 .1/ o VLAN for 12 Academic heads and 1 printer is: academic heads (12 PC) 192.168. 10 .59-62/24, printer 192.168. 10 .63/
Figure 9 : Manager room design
- 1 st^ Floor: One the 1st^ floor only have LAN-floor room that used as a student’s room
o In this room includes 25 PC for students and 1 switch
o WAP for all user in 1st^ floor and uses IP address: 192.168.20.1/
o VLAN of 25 student’s PC is: student (25 PC) 192.168.20.54-59/
Figure 10 : 1 st^ floor design
- 2 nd^ Floor: On the 2nd^ floor have LAN-floor room that used as a student’s room
o In this room includes 25 PC for students, 1 switch and 1 server.
o WAP for all user in 2nd^ floor and uses IP address: 192.168.20.1/
o VLAN of 25 student’s PC and 1 server: student (25 PC) 192.168.20.53-55/24, server

2. Evaluate the design to meet the requirements (P6)
2.1. Test plan
o In ground floor, floor 1 or 2 can ping to rooms of other floors and ping each other. And from computers in diferrent rooms can ping these servers. o The 1st^ and 2 nd floors include student computer labs, from the machines in these 2 rooms can access dns, dhcp etc. Can also ping each other. o All room can use the wireless network. o The system is installed correctly and the network can be used. To improve safety for network system, it should have support the installation of a firewall system.
2.2. Evaluate my network design
Advantages Disadvantages
o Easy to understand and maintain with simple and effective design. The layout is clearly dividef into 3 floors. o All floor are installed wireless network. o Rooms are pingable to each other with low latency. o Network system has 2 server, one for ground floor and one for 2nd^ floor. o Complete security for routers. o Incomplete firewall and security system. o Still missing many servers o Because system is simple, so it’s easy to have a lack of network bandwidth when all rooms are operating at maximum capacity. Table 3 : Evaluate my network design
2.3. Advice and solutions
o Use more than 1 router and 1 switch in floors 1 and 2. o The addition of switches on the 1st^ and 2nd^ floor can also provide additional ports to use wireless, it’s help students can alse use the Internet for learning. o Should be upgrade security system and firewall as soon as possible.
