Trang 51 INTRODUCTION
To present the basic knowledge of networking I have learned and implemented 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
2 LOGICAL/PHYSICAL DESIGN OF NETWORK SYSTEM
2.1 The difference between Logical and Physical design
architecture[ CITATION Cra06 \l 1033 ] For infrastructure projects, the architecture may be a series of blockdiagrams showing networks, service components, and network connection elements It should benecessary to indicate how other components outside the scope of the project interact with the topic of the
external entities, and the flows of data into and out of these entities The Logical Design will be the IPstructure of your network[ CITATION Joh10 \l 1033 ]
topology it'll show what kind of technology are utilized, like Ethernet, fiber, ISDN, cable, or whatever are
physical design of the network displays the physical location of the connections among devices joining on
computer icons, servers with full tower cases, and switches and other similar devices are displayed assmall rectangular boxes
architecture In the other word, it refers to the arrangement of computers and other physical components
logical design network supposes a specific section of a conceptual design in a network and assigns it a
Cra06 \l 1033 ]
2.2 User requirements for general network design
Trang 6User requirements is that the set of requirements gathered or derived from user input and is what's needed by
attached that network design is taken into account a potential user Some of user requirements for general networkdesign 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, networkdesigners 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 requirementsbelow:
Objects:
Actual Resources: 50 student lab computers, 35 staff computers, and 3 printers
System structure: 3 floors, all system computers and printers are on the ground floor apart from the IT labs – onelab located on the first floor with 25 lab computers and another located on the second floor with 25 left computers.Prepare for design:
Trang 7Logical design based on user requirements
Computers are separated into three floors to suit with requirements 4 Computers representing for 50 labcomputers on first and second floor, the others are set for different functions room in ground floor And each switch
is set for each floor
Figure 1: Logical design
Trang 8Particularly, there is setting network:
because one switch contains 24 port so that this can connect more computer to representing for 25 labcomputers only with 2 lab computers
representing left 25 computer
and marketing room(representing for 12 AD & MAR computers); 2 for Manager room(representing for 5computers); 2 for Network admin room(representing for 3 computers) and 1 router, 1 switch , 3 printers
o In my logical network design I do not provide ip address for each computer as usual, but I give the addressthrough DHCP server Specifically, i configure one router(1941) with host name "R-Center" With the arouter(R-center) configuration, it sets the full DHCP server implementation that assigns and manages IP
Figure 2: Configure DHCP R-center
Trang 9addresses from specified address 3 pools within the router(R- Center) through GigabitEthernet ports tocomputers in 3 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 3 floorswhich 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 3 floors in my network design The IP address configured on the router(R-center) beautomatically excluded from the DHCP address pools I do this task to exclude addresses from the pool ifthe DHCP server ought to not assign these IP addresses
o When I done configure and set up the router R-Center, most computers also still ignored the IP addressesfrom DHCP server Therefore, I configured IP helper-address as a "middle man" in interface configurationmode on the router (R-Floor) that is connected to the 2 labs on 2 floor through 2 GigabitEthernet0/0 and0/1 in which provide DHCP IP addresses
Figure 3: Configure Excuded addresses
Figure 4:Configure IP helper
Trang 10Configure an IP Helper address which pass through the serial 0/1/0 of R-center connecting to R-Floor toensure that devices on that GigabitEthernet0/0 and GigabitEthernet 0/1 parts can receive DHCP IPaddress from the DHCP Server (R-Center)
o From these configuration of 2 router R-Center and R-Floor, all computer also received IP Address DHCP
o Physical design based on user requirements
Figure 5: Physical design
Trang 11Explaination : 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, secondfloor for lab students, ground floor for Teachers, Staffs, Managers-Marketing and Network Administrators)
o On ground floor we have 8 PCs, 1 switch and 3 Printer
o On first Floor this network design has 2 PCs, 1 switch
o On second Floor this network design has 2 PCs, 1 switch and both first and second floor use together 1router
Address Table
There is the addressing table of the given diagrams above:
Device IP Address Subnet Mask Default Gateway AD-MAR PC 1 192.168.1.7 255.255.255.0 192.168.1.1
AD-MAR PC 12 192.168.1.2 255.255.255.0 192.168.1.1
TEACHER PC 1 192.168.1.5 255.255.255.0 192.168.1.1
Trang 123 Evaluate the design
TEST SCHEME for a general network:
NETWORK AND CHECK IP DHCP RECEIVED
Trang 136. Capable of pinging from LAB-PC50 to every devices of the
devices connected to the switch0
Allowable
Evaluatation of the network design:
For my design of network can meet the user requirements, I designed and set it in the simple structurewhich is quite similar to Star topology structure Designing it like that since this structure is not too complicated for
me as far as ensuring the stability of connection between devices, adjusting when edit the network becomeconvenient, the network can be adjusted to be expandable or narrowable in the scope of user computers
In addition, when I set up to this design of network, i realized that the system of network operates depend onthe original fixed connection The operating of network only need to the router R-center or R-floor and 3 switcheswhich support supply IP have no problems and operate properly So, even if in case these are networkingcomputer devices around have an information node gets error, the network still operate as usual
Here are some Pros and Cons of of my network design based on user requirements:
o The two main routers have high security
o Don't need to spend time to enter the IP address for each computer and network device because ofhaving the function of provide IP address through DHCP
o Ping through each other fast and smoothly networks Almost no request time out
o Expendable and narrowable
Trang 14o The Internet connecting speed, network transfer nodes and IP address provider depend almost on therouting provider, there is no backup solution in case routing provider get some problems or trouble.
o Having quite much cables used in network lead to the cost for equipment will rise significantly if thisnetwork set up in actual environment
o Except 2 main router, network computers and others network devices still have weak security
o Using wireless or other cheaper connection methods to decrease the cost of setting up network
o Configure the retriction of access rights for particular network devices
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:

Trang 16To 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

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:
second is serial DCE like the network shown logical network design in part 2
R-FLOOR 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
Figure 13: Diagram of overall network realization
Trang 22o Configure a password for all vty connections
The next step after basic configuring for 2 router is configure ip address for 2 routers
Figure 15: CONFIGURE IP ADDRESS FOR R-CENTER AND R-FLOOR Figure 14: BASIC CONFIGURE IN R_CENTER AND R-FLOOR
Trang 23Enable OSPF in both routers.
Trang 24I configured a DHCP Server from R-Center
And at the same time I configure ip DHCP excluded in R-Center as wellAfter all, I configure IP-helper in R-Floor:
Then, I can easily get ip-DHCP in every devices in this network:

Overall evaluation: According to the test 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, mynetwork system also meets the original user requirement of local educational institute, it ensure the ability to ping
Trang 30and connect between devices set in 3 floors The evidences also given above to prove that the network systemhas 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 improvenetworking security.
