the network solution for the problem, this report will presents and explains the process from designing solutions to implementation of the network designed with the given problem in the scenatio of assignment LOGICAL/PHYSICAL DESIGN OF NETWORK SYSTEM 2.1 The difference between Logical and Physical design Logical design takes every bit of conceptual design and assigns it to a particular logical role within architecture[ CITATION Cra06 \l 1033 ] For infrastructure projects, the architecture may be a series of block diagrams showing networks, service components, and network connection elements It should be necessary to indicate how other components outside the scope of the project interact with the topic of the migration[ CITATION Dav08 \l 1033 ] Graphical representation of a system showing the system’s internal and external entities, and the flows of data into and out of these entities The Logical Design will be the IP structure of your network[ CITATION Joh10 \l 1033 ] Physical design of a network refers to the particular layout of the physical a part of a network, the topology it'll show what kind of technology are utilized, like Ethernet, fiber, ISDN, cable, or whatever are going to be used[ CITATION Joh10 \l 1033 ] The physical design will show the constellation to be used The physical design of the network displays the physical location of the connections among devices joining on the network[ CITATION Dav08 \l 1033 ] In these diagrams, workstations are commonly represented with tiny computer icons, servers with full tower cases, and switches and other similar devices are displayed as small rectangular boxes Physical design layout shows the sections of the logical design network which are in a provided network architecture In the other word, it refers to the arrangement of computers and other physical components Its components consists Fiber, ISDN and Ethernet [ CITATION Cra06 \l 1033 ] Unlike the physical design,the logical design network supposes a specific section of a conceptual design in a network and assigns it a logical role in a within that framework Its components consist of IP structures of the network[ CITATION Cra06 \l 1033 ] 2.2 User requirements for general network design User requirements is that the set of requirements gathered or derived from user input and is what's needed by users to user the good network design[ CITATION Jam03 \l 1033 ] Typically, when gathering requirements, everyone attached that network design is taken into account a potential user Some of user requirements for general network design can be told as Interactivity, presentation quality, functionality, supportability and future growth Thus, designing a network can be a challenging task To design reliable, expendable internetworks, network designers must realize that components of an internetwork have distinct design to meet user requirements From there, there are design and implement the networking project based on the specific user requirements below: Objects: 200 students 15 teachers 12 marketing and administration staff higher managers including the head of academics and the programmer manager computer network administrators Actual Resources: 50 student lab computers, 35 staff computers, and printers System structure: floors, all system computers and printers are on the ground floor apart from the IT labs – one lab located on the first floor with 25 lab computers and another located on the second floor with 25 left computers Prepare for design: 12 PCs Printer Router (1941) Switch (2960) Logical design based on user requirements 1: Logical Explaination: In this network design, Figure I utilize 12 design Computers, Printers, Switches and Routers 12 Computers are separated into three floors to suit with requirements Computers representing for 50 lab computers on first and second floor, the others are set for different functions room in ground floor And each switch is set for each floor Particularly, there is setting network: On first floor, Student Lab has computers, switch The reason why student Lab has switch is because one switch contains 24 port so that this can connect more computer to representing for 25 lab computers only with lab computers On Second floor, Student Lab has computer, switch Switch connected computer is enough for representing left 25 computer Staff room has computers include: for teacher room(representing for 15 teacher computers); for Admin and marketing room(representing for 12 AD & MAR computers); for Manager room(representing for computers); for Network admin room(representing for computers) and router, switch , printers Configure IP Address: o In my logical network design I not provide ip address for each computer as usual, but I give the address through DHCP server Specifically, i configure one router(1941) with host name "R-Center" With the a router(R-center) configuration, it sets the full DHCP server implementation that assigns and manages IP addresses from specified address pools within the router(R- Center) through GigabitEthernet ports to Figure 2: Configure DHCP R-center computers in floors which use ip address supplied DHCP server o Simultaneously, i also configured to allocate additional parameters such as the IP address of (DNS) server(which is set 192.168.11.5) and the default router is set to GigabitEthernet of each switch in floors which support to provide ip addresses through DHCP o I also performed the other task to define IP excluded addresses that the DHCP server ought to not assign to computers in floors in my network design The IP address configured on the router(R-center) be automatically excluded from the DHCP address pools I this task to exclude addresses from the pool if the DHCP server ought to not assign these IP addresses Configure Excuded addresses o When I done configure and set upFigure the3:router R-Center, most computers also still ignored the IP addresses from DHCP server Therefore, I configured IP helper-address as a "middle man" in interface configuration mode on the router (R-Floor) that is connected to the labs on floor through GigabitEthernet0/0 and 0/1 in which provide DHCP IP addresses Figure 4:Configure IP helper Configure an IP Helper address which pass through the serial 0/1/0 of R-center connecting to R-Floor to ensure that devices on that GigabitEthernet0/0 and GigabitEthernet 0/1 parts can receive DHCP IP address from the DHCP Server (R-Center) o From these configuration of router R-Center and R-Floor, all computer also received IP Address DHCP o Physical design based on user requirements Figure 5: Physical design Explaination: In this physical design above, I have did set up device to suit all the requirements from the local educational institute: o Doing separate the devices in in conformity with each floor according to requirements (first floor, second floor for lab students, ground floor for Teachers, Staffs, Managers-Marketing and Network Administrators) o On ground floor we have PCs, switch and Printer o On first Floor this network design has PCs, switch o Set up more backup service provider for averting case the main routing provider gets fails o Usually examine and upgrade software and firmware of switch, router and any network devices Test Plan: Test No Test plan Description Ping from Network Administrator pc to Teacher pc Open

Figure 6: Perform test To implement the network system, i have some proof screenshots Each screenshot demonstrates the process when I implement these pinging tasks from the test plan above and here are some provided proof srceenshots below: Figure 7: Perform test Figure 8: Perform test Figure 9: perfrom test Figure 10: Perform test Here are all screenshots which is the proof of the my network implementation Figure 11: Perform test Figure 12: Perfrom test Figure 13: Diagram of overall network realization Diagram of my overall network realization Step-by-step how to configure networking devices and computers in the network After provide the screen shots above to prove my network can be implemeted properly, it obviously that it is needed to provide configuration networking step-by-step: First of all, I connected the devices together through main cables, one is Copper straight-through and the second is serial DCE like the network shown logical network design in part After completing the cabling of the devices, I continue configured basic configuration of R-CENTER and RFLOOR according to the following instructions: o Configure the hostname of devices o Turn off DNS lookup o Configure a privileged EXEC mode password o Configure a message-of-the-day banner o Configure a password for the console connections o Configure a password for all vty connections Figure 14: BASIC CONFIGURE for IN R_CENTER AND The next step after basic configuring router isR-FLOOR configure ip address for routers Figure 15: CONFIGURE IP ADDRESS FOR R-CENTER AND R-FLOOR Enable OSPF in both routers I configured a DHCP Server from R-Center Figurefrom 16: Enable OSPF with process ID Figure 17: DHCP server R-CENTER And at the same time I configure ip DHCP excluded in R-Center as well Figure 19: IP-Helper configure Figure 18: IP DHCP excluded-address After all, I configure IP-helper in R-Floor: Then, I can easily get ip-DHCP in every devices in this network: Document and analyse

results and implemetation process, I can make a conclusion that the network system operates properly and the process is implemented as I expected about it In addition, my network system also meets the original user requirement of local educational institute, it ensure the ability to ping and connect between devices set in floors The evidences also given above to prove that the network system has almost no delay or mistakes when working Not only that, the network system also can be upgraded system, expand more computers using the network wireless access point devices and set up firewall to improve networking security CONCLUSION On the whole, I have learned and understand partly the way how to design and implement a simple network project and particular is a simple educated institution based on their requirements from completing this assignment In the future, I perhaps will learn and research more about networking to improve other larger scaleprojects and try developing more
