I. Provide a logical / physical design of the networked system with clear
explanation and addressing table (P5)
- Logical and physical design a. Logical design A logical network is a virtual representation of a network that appears to the user as an entirely separate and self-contained network even though it might physically be only a portion of a larger network or a local area network. It might also be an entity that has been created out of multiple separate networks and made to appear as a single network. This is often used in virtual environments where there are physical and virtual networks running together; so, out of convenience and function, separate networks can be made into a single logical network. b. Physical design A physical devices and cable connections between them is on the mapping of your physical network topology. The topology diagram in a physical network is icons of elements such as workstations, servers, routers and switches, and cable connections is the line between them. A physical network design infrastructure needs to look like and how to interconnect all the devices.. There are the main characteristics of physical design: Evaluation of environmental conditions relating to physical media type required Placement and configuration of zone enclosures Space planning, pathways, routing Physical media required based upon logical design consideration c. Different between logical and physical of the networked system Logical design of network consists of virtual design while the physical design of a network describes the hardware function of the network. Logical designs determine the flow of data or communication between two networks while physical design is a communication between two computers connected with cables. For example: A physical design of a network can be upgraded to link two or three office buildings. The expansion would require an upgrade using logical design layout of a network. This would make it easy for information to be process from and system in buildings at the same time.
- User requirements for general network design a. Determining networking requirements First step is to understand your networking requirements. Networking devices must reflect the goals characteristics, and policies of the organizations in which they operate. Two primary goal drive networking design and implementation: Application availability – Networks carry application information between computers. If the applications are not available to network users, the network is not doing its job. Cost of ownership – information system (IS) budgets today often run in the millions of dollars. As large organizations increasingly rely on electronic data for managing business activities, the associated costs of computing resources will continue to rise. b. The design problem These three general factors are part of the network design problem: Environmental donations: are the location and predicted environmental traffic of hosts, servers, terminal and other end-points as well as projected expenses to provide different levels of service. Networking variables: it encompasses the topology of the networks, lines and assignments of packet flows. The objective is to minimize costs. These problems are mainly unlikely. Performance limitations: are network dependability, traffic performance, and computer speeds for host/clients c. Assessing user requirements Response times, throughput, and reliability are key components of application usability: 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. Apart from end-to-end connection, applications with large volume 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. Reliability is always crucial, there are legitimate demands on certain application that surpass conventional needs. Some examples are emergency/police/military operation 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.

II. Evaluate the design to meet the requirements (P6)
- Test plan for the design
- All room can use the wireless network,
- All floor can ping room within them and they can also ping at each other,
- Machine in floor 1 and 2 with access dns can ping at each other.
- Evaluate my network design Benefits Clear and simple, very easy to maintain and update Highly secured between router Machines place in different room can still ping at each other Network system has 2 servers, one for 1st^ floor and one for 2nd^ floor Drawbacks Many servers still unavailable When all room operating at maximum capacity of bandwidth it can running into some issues Incomplete security system
- Some of the solutions More fund needs to be invented to upgrade security system Add more switches to free some of the bandwidth capacity Use more router in floor 1 and 2
