with each other The main issue discussed and explained is the customer's requirements for the network to be designed It's a system for a local educational institution with 50 lab computers, 35 staff computers, and printers, all with dynamic IP addresses Based on that request, a logical design will be provided along with a physical design and an IP address table Next, a test plan will be created along with the evaluation of this network system, the solution will also be given to overcome the shortcomings The network design process will be displayed along with the overall results table of the devices Finally, show the results of the testing process and compare it with the customer's original request P5 Provide a logical/physical design of the networked system with clear explanation and addressing table The difference between logical and physical design Logical network design: Connections and interactions between network devices are described in logic diagrams Relationships describe how devices connect to each other, how they collaborate to provide network services and support, and respond to user requests (McCabe, 2007) Figure 1: Physical Topology A physical design showing how devices are connected to each other in a network along with wires and cables It reveals the network topology with everything physical: cables, servers, PCs, etc It clearly describes the location of devices in a work environment such as a school or company Figure 2: Logical Topology Difference between physical and logical design: In comparison to physical design, logical design is more intellectual and abstract The logical links between the items are examined in logical design Physical design considers the most efficient method of storing and retrieving things (Davis, 2021) The demands of the end users should be the focus of your design Logical design underpins the development of the physical design because it will provide the devices, their topology From there, new physical designs can develop Logical network diagrams are used to show how traffic flows throughout a network, as well as IP addresses, admin domains, domain routing, and control points A physical network diagram should, in theory, depict the network architecture in its current state, including all devices and their connections (Davis, 2021) About advantages of logical design, If Service is shared across two IP addresses, a logical network diagram can be used to rapidly rule out a firewall issue Using logical network diagrams, you may double-check that your firewall rules are still correct Using logical network diagrams, you can easily see what isn't redundant and what is About disadvantages, the specific location of the devices and their storage space is unknown About advantages of physical design, specify the location and space of the equipment Observe the connection of devices together with cables Based on that structure to find out where the error occurs or is not optimal for the transmission line to change About disadvantages, failed to test how devices are connected to each other and other logic related things If there is a software error, this design cannot be relied on to find the problem to fix The user requirements for general network design A network system for the local educational institution, it must meet the customer's goals in several ways In terms of volume requirements, this network must accommodate 50 student lab computers, 35 staff computers, and printers In addition, a File Server will also be added to the system to serve the needs of the machines Regarding connectivity, the machines in this system must be able to connect to anywhere in the network to easily exchange data and manage the system About the design, build 35 staff computers on the 1st floor, on the 2nd and 3rd floors are two labs for students, the design must have a clear location, the design is optimal and simple because of the purpose of use For educational purposes only, the clearer the physical design, the easier it is to install A reasonable proposal for equipment for this network is switches and routers, these routers connect directly to each other router acts as a dhcp server to give dynamic ip addresses to all switches and connect directly to switches, one router configures ip helper and connects directly to the other switches Each lab connects to a switch, the admin and manager rooms connect to a switch, and the teacher and marketing rooms connect to a switch In terms of latency, low latency is the desire of every network system, the transmission speed must be as fast as possible for employees to work most effectively In terms of cost, this is a simple network system, so the cost should not be too great, the equipment should be considered for optimal price but must not affect the long-term performance of the network In addition, in the future, new machines may be added to the network, so the number of ports must be left over Therefore, the switches used in the staff room are 24 ports (their prices are cheap), the lab switches are 48 ports (due to future development) Using multiple switches is due to the convenience of installation and the floors not depend on each other Finally, security is necessary to protect the information of employees, students and data in the network Logical design Requirements are 50 PC-student, 25 PC-Staff, Printers, File server Due to the large number of devices, the number on the logical design is representative only The design has floors and rooms, including routers and switches Figure 3: Logical design a) Floor Includes switches for rooms Switch SA_M is connected to the Admin room and the Manager room along with PCs of the Marketing department The IP address of this switch is 192.168.3.1/255.255.255.0 with VLAN 20 for connections Switch ST_M is connected to Marketing department and Teacher room The IP address of this switch is 192.168.4.1/255.255.255.0 with VLAN 10 for connections These switches are connected to the RS router Figure 32: IP address of a PC-Manager Figure 33: IP address of a PC-Marketing 30 Figure 34: IP address of a Printer Figure 35: IP address of a PC-Lab1 31 Figure 36: IP address of a PC-lab 32 Show overall network realization Figure: Diagram of overall network realization P8 - Document and analyse test results against expected results Implementation process a) Devices About switch, use switches 2960L-24TS and switches 2960L-48TS The 48-port type is used for labs on the 2nd and 3rd floors because the number of computers in each room is 25, in the future, the number of computers can be increased The 24-port type is used on the first floor because of the small number of computers About router, use routers 1941 because its price is cheap and the network system is not too complicated One router is responsible for DHCP server, the other router is set up IP helper In the future, the internet will be connected to the router Regarding the Server, use a FileServer as the network's internal data storage center, located in the Admin room Regarding computers, using 85 computers, of which 50 are for the lab, 35 are for staff, including PC-Admin, 12 PC-Marketing, 15 PC-Teacher, PC-Manager They are divided into their respective rooms About Printer, use printers for rooms as manager, marketing, and teacher to serve printing Although it was not included in the original requirement, the printer is an essential device for school networks b) Connection 33 switches 2960L-24TS are directly connected to the RS router via the Fa port on the 1st floor Connect the switch to the PC, printer, and server devices on the 1st floor via the Fa port Set up VLANs for connected ports switches 2960L-48TS are connected directly to the RST router via port Fa on the 2nd and 3rd floors Connect the switch to the PCs on the 2nd and 3rd floors via the Fa port Set up VLANs for connected ports Router RS connects to router RST by Serial port and vice versa RS connects to 24-port switches using Giga ports, RST connects to 48-port switches using Giga ports RS is set up with password, banner, name, ospf, IP address and ip dhcp pool to give dynamic IP addresses to devices in switches RST is set up banner, name, password, ospf, ip address and ip helper to help lab 1,2 PC can get dynamic IP address from RS The server is located in the admin room and is connected to the Fa port of the switch and is set to DHCP mode The computers are all connected to the switch and set to DHCP mode to receive dynamic IP addresses The printers are also set to DHCP mode Test and show result Ping from Admin to all rooms: Figure 37: Ping from PC-admin to PC of manager, marketing, teacher, lab1 room 34 Figure 38: Ping from PC-admin to PC of Lab2

room), 192.168.3.6 (Server of Admin room) Evaluate the results: All devices in the rooms can ping each other The failure rate is 0%, which proves that this network is working very well, and the speed is also very fast This network system has met the customer's initial request that all computers in the system be connected smoothly The design is basically finished 40 Conclusion In this assignment, logical and physical design were introduced to the concept along with the differences between them User requirements were also specifically evaluated along with an initial solution The logical design of this network has been built and analyzed along with a physical design To build the system, a table of IP addresses of all devices is also provided A test plan is needed for the testing process along with an assessment of the advantages and disadvantages and a solution for those disadvantages The whole process of configuring the provided devices such as VLAN, DHCP and displaying the interface after the configuration is complete The execution is reported, it includes the devices used, their connection process Finally, the test plan is made along with the recording of those results and the overall assessment 41 Reference list McCabe, J., 2007 Network Analysis, Architecture, and Design 3rd ed Morgan Kaufmann, p.408 Davis, B., 2021 What is the difference between logical design and
