<b>P5. Provide a logical/physical design of the networked system with clear explanation and addressing table.</b>

<b>1.Network design</b>

 Network design is a category of systems design that deals with data transport mechanisms. As with other systems' design disciplines, network design follows an analysis stage, where requirements are generated, and precedes implementation, where the system (or relevant system component) is constructed. The objective of network design is to satisfy data communication requirements while minimizing expense. Requirement scope can vary widely from one network design project to another based on geographic particularities and the nature

<b>of the data requiring transport. </b>

 Network design is a complicated process involving evaluating and scoping the network to be implemented. The design process is typically depicted in the form of a network diagram, which is the blueprint for the physical implementation of the network. Network design will typically include the cabling structure, a logical map of the network to be implemented, the quantity of network devices, the type of network devices, the location of network devices, the IP addressing structure, and the network security architecture.

 Network design divide into 2 type:

 Logical design Physical design

you would locate key distribution points for the network as well as what types of devicesand switches you should use to interconnect the plant. It can also include how to do IPaddresses, VLANs, and switch configurations. Below are key features of the Logical Design:

 IP Address Scheme and Subnetting VLAN Selection

 Access and Distribution Layer Switch types, models and ports. Typical configurations based upon standards

 Logical Plant Floor layout

<b>1.2.Physical design</b>

 A Physical Network Design determines what the physical infrastructure needs to look like and how to interconnect all the devices. Key features of the Physical Design are:

</div><span class="text_page_counter">Trang 10</span><div class="page_container" data-page="10">

 Space Planning, Pathways, Routing Placement and Configuration of Zone Enclosures

 Physical Media required based upon logical design considerations i.e. fiber, copper,conduit types, etc.

<b>1.3. The difference between logical and physical design</b>

 The logical design is more conceptual and abstract than the physical design. In thelogical design, you look at the logical relationships among the objects. In the physicaldesign, you look at the most effective way of storing and retrieving the objects. The primary difference between logical network design and physical network design is

that of iterative production of a solution from the identification of a problem. Forexample, when a business needs to share information in real-time with remote offices,they are thinking in terms of business first and technology second. This is whereidentification of a problem begins, and as the problem is documented, it can beiteratively evolved from a logical solution into many possible physical designs. Thelogical design of a network can be re-implemented with new technology, and yet thelogical design remains the same. Logical designs can span generations of technology,

<b>2. Requirement analysis from given scenario</b>

 The scenario that requires me to design a networked system that includes:

 People: 200 students, 15 teachers, 12 marketing and administration staff, 5 highermanagers including the academic heads and the programming managers, and 3computer 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 ITlabs – one lab located on the first floor and another located on the second floor.

 I analysed this scenario and I decide to design a network system with:

 Target:

 All computers can connect to the Internet and communicate with each other. My design networking system is an optimal networking system and matches the

requirements of the scenario.

 The administrator can access all computers.

 Structure:

 Two Lab room is placed on Floor 1 and Floor 2.

 In-Ground, we have 4 room, including: IT room, Higher managers room, Marketing room,Teacher room.

 The second router is responsible for connecting the IT room with the server system (DNS,WEB, FTP,SMTP) to the building's network.

 3 routers are connected to each other through a ring structure

 The topology used here is the hybrid topology: Advantages:

 If an error occurs in any part of the network, it will not affect the operation of the restof the network

 The size of the network can be easily expanded by adding new devices withoutaffecting the functionality of the existing network.

 This topology is very flexible as it can be designed according to the requirements of theorganization.

 The hybrid topology is very effective because it can be designed in such a way that thestrength of the network is maximized and the weakness of the network minimized.

data of each department. For security, the company can buy a hardware firewall to createrules, so it can prevent outside attacks.

<b> Implement monitoring and automation</b>

 Due to an uptick in the complexity of modern networks that operate at higher layers withinthe OSI model, visibility into layer 7 data flows is becoming increasingly important. Whenplanning for your new network, be sure that you have the necessary network performancemonitoring tools in place to help you quickly identify and resolve application-specificproblems in a short amount of time. These tools help identify common problems so theycan be easily resolved using proactive automation techniques. Increasing the growth of thenetwork, the switches and more access points will be added that helps the network toexpand meaning your business/organization also expand and the outcome of yourbusiness increases.

<b> Upgrade the network switch</b>

 Once you upgrade your switch you conserve energy efficiency was not a major concern inthe past, but network equipment manufacturers are now paying more attention to theissue and installing more efficient power supplies and fans. The improvements are usuallynot sufficient to justify replacing a switch but they are a bonus when upgrading for otherreasons. The decision to replace equipment should be made carefully even in the best oftimes. Current conditions dictate extra diligence, but new technology and applications canyield overall savings that make upgrades worthwhile

Current conditions dictate extra diligence, but new technology and applications can yieldoverall savings that make upgrades worthwhile

 The network is configured with a wired router with the latest and new technology ofwireless routers, you need not have a USB or any other means for the port and be involvedin carrying different types of devices for a file transfer, with the latest wireless connection,you can easily transfer your files from one source to another. Different types of clouds likeOneDrive, Google Drive, iCloud are on your devices these days where you can store as wellas let other people see your files without having to have a single device for putting in aport, sharing files and then removing it. With the advancement of Wireless routers, onedoes not need to have any care or worry about me.

<b> Upgrade</b>

 With the advancement of Wireless routers, one does not need to have any care orworry about the surroundings, wireless routers whenever they are able to work cangive you a tremendous amount of speed without having to have any wires attached toyour device. All you have to have is your device and you can move freely from oneplace to the other, within the required range without having to worry about anything,
