A physical network design will actually depict the network architecture in its current state, including every device and their connections. Physical diagrams contain things like ports, cables, racks, servers, particular models, and other physical components of the network since they show all of its physical components. The term L1 refers to physical diagrams in the OSI model of networking. So, if youre utilizing automated mapping software, a physical network diagram may be a networks server diagram, a networks cabling diagram, a racks diagram, or a combination of other sorts of interactive diagrams that enable you to examine what you need to see. Because physical network diagrams depict the entire topology of the physical network, they can include a number of different components: Connections: For a physical network diagram to work, connections are essential. The physical wiring that links the actual devices in a network is shown as connectors (also known as connections). Each connections ends should be marked with the port it connects to as well as the location of its termination. You may depict variations in detail using a variety of colors, line kinds, and thicknesses depending on how detailed you need to be. Labels: When a physical diagram employs generic icons, labels help the viewer understand what they are looking at. Switches, routers, firewalls, and other network devices should all have their hostname and IP address clearly displayed on them. Even while a device is active and managed somewhere else, it should nevertheless have a label (perhaps in a different typeface to set it apart from the different network hardware). Diagram legend: A diagrams legend explains to the viewer what each object and link in the diagram means. The legend translates the many images, icons, and colors and provides context for their use. You would mention this in your legend if, for instance, you used double black lines to symbolize a particular kind of fiber cable. Switch Stacks: Switch stacks are typically portrayed as a single object or device. They perform similarly to a chassis switch.

brief/project, The CEO Mr Nguyen is happy with your first report and now he has asked that a new specification be analyzed for the institution as given Part of the task is to design and implement the networking project within a given timeframe as given earlier The essential task required is to design efficient networked system following the below task or step: • Prepare a written step-by-step plan of how you are going to design a Local Area Network including a blueprint for LAN Justify the choice of devices for the network design • Justify the choice of devices for the network design • Produce a test plan to evaluate this design for the requirements of bandwidth and cost constraints as per user specifications • Justify the security requirements and quality of services needed for the selection of accessories • Suggest a maintenance schedule to support the networked system Assignment Task 1: Provide a logical/physical design of the networked system with clear explanation and addressing table: A: Discuss about logical design physical design: Logical design: -The logical network design is composed of segregated networks that are implemented physically using virtual local area networks (VLANs) defined by network switches The internal network uses private IP address space (10.0.0.0) for security and portability advantages (Ivypanda, 2012) • Subnets (such as IP addresses, VLAN IDs, and subnet masks,) • Network objects (routers and firewalls) • Specific routing protocols • Routing domains • Voice gateways • Traffic flow • Network segment Figure 1: example about logical design (Odessa, 2022) As the information contained within logical network diagrams corresponds to the L3 (Layer 3) of the OSI model; L2 devices (such as switches) are not depicted in an L3 or logical network diagram While physical network diagrams are important, logical diagrams make network management easier in the following ways: Troubleshooting: If service is out somewhere between two IP addresses, you can use a logical network diagram to quickly rule out an issue caused by a firewall Firewalls: With logical network diagrams, you can ensure your firewall rule bases stay accurate Eliminate redundancies: Logical network diagrams will clearly help you determine what isn’t redundant — and what is Capacity planning: Although physical network diagrams are instrumental in capacity planning, logical diagrams also help With them, you can map out expanding or changing the network and see what will impact what Sharing network information: If you need to share information about the network, but want to conceal physical information about the network, you can use a logical network diagram Physical design: A physical network design will actually depict the network architecture in its current state, including every device and their connections Physical diagrams contain things like ports, cables, racks, servers, particular models, and other physical components of the network since they show all of its physical components The term "L1" refers to physical diagrams in the OSI model of networking So, if you're utilizing automated mapping software, a physical network diagram may be a network's server diagram, a network's cabling diagram, a racks diagram, or a combination of other sorts of interactive diagrams that enable you to examine what you need to see Because physical network diagrams depict the entire topology of the physical network, they can include a number of different components: Connections: For a physical network diagram to work,

address clearly displayed on them Even while a device is active and managed somewhere else, it should nevertheless have a label (perhaps in a different typeface to set it apart from the different network hardware) Diagram legend: A diagram's legend explains to the viewer what each object and link in the diagram means The legend translates the many images, icons, and colors and provides context for their use You would mention this in your legend if, for instance, you used double black lines to symbolize a particular kind of fiber cable Switch Stacks: Switch stacks are typically portrayed as a single object or device They perform similarly to a chassis switch The differences between logical and physical design: PHYSICAL DESIGN LOGICAL DESIGN Depicts the physical layout of the network Depicts logistics of the network concerned wthe ith transmission of data The layout can be modified based on the needs There is no interference and manipulation involved here It can be arranged in star, ring, mesh, and bus topologies It exists in bus and ring topologies This has a major impact on the cost, scalability, and bandwidth capacity of the network-based the on selection and availability of devices This has a major impact on the speed and delivery of data packets It also handles flow control and ordered delivery of data packets It is the actual router concerned with the transmission It is a high-level representation of data flow The physical connection of the network Data path of followed of the network Table 1: compare physical and logical design B: requirement: - People: 20 students, teachers, 12 marketing and administration staff, higher managers including the head of academics and the programmer manager, and computer network administrators - Resources: 50 student lab computers, 35 staff computers, printers Building, floors - 1st floor for students and teachers and 2nd floor for network groups: marketing and management, third floor for administration and server * Scalable: A scalable network can swiftly expand to accommodate new users and applications while retaining the quality of service already provided to existing customers * Security: The security of a network is always a critical issue for every network All systems and networks must be monitored, and unauthorized access to management software that exists on them must be prevented * Cost: The goal is to keep costs as low as possible based on these components, therefore network devices in the system must meet the needs of users while also allowing the system to grow and expand effectively C: Physical design of network based on the specific requirements Figure 2: The design with floor With the requirements of the problem, a design was conceived with available connections and devices First of all, there are servers including DNS server, Http // and DHCP server The devices are arranged with different layers and functions, depending on the requirements and wishes of the users On the first floor is the student and teacher floor with a DHCP server and a switch along with the labs of students and teachers in the school 2nd floor: there is one more DHCP of Marketing and Management segment with labs in addition to the appearance of wireless connection 3rd floor: this is the level of admins that are completely private and very secure here are mainly servers like DNS
