one is IoT server for controlling IoT devices and another one is DHCP server for provide IP among those
devices.Then I took some end devices and some smart devices for controlling those ioT device .Also took
acces point for wireless connection between smart device and IoT.

7.  Smart Office

12.  LAN
Local Area Network (LAN) .

13.  PAN
PersonalArea Network .

15. Topology Network Design
 Bus Topology:
Bus topology is a network type in which every computer and network device is connected to
single cable.
Now configure the IP in the nodes.

18.  Ring Topology
Where each computer is connected to another computer, with the last one connected to the first.
Exactly two neighbours for each device.it is called ring topology.

19.  Mesh Topology
Mesh topology is a point-to-point connection to other nodes or devices. Here all the network
nodes are connected to each other.

21.  Star Topology
A star topology is a topology for a Local Area Network (LAN) in which all nodes are
individually connected to a central connection point, like a hub or a switch.

23.  Hybrid Topology
A combination of two or more topology is known as hybrid topology.

27.  DHCP Server Configuration :
DHCP means Dynamic Host Configuration Protocol.Here IP address provides among the user
dynamically.Below the configuration ,
First go to the router and set the IP 192.168.1.1 then click port status on .
Next just follow those Screen snap by order and perform those task which is present on snapes.

30. Now go the end devices click on Desktop>IP configuration then click on DHCP .Then the pc got
automically IP address .(follow snaps below )

31. Now checking the configuration

32. So the message send is successful..
 WEB Server Configuration:

36. Now checking the configuration,
Go to any end device >Desktop>web Browser then type the URL box on web server IP
192.168.5.3(follow the snap)
So the Configuration Successful.

37.  DNS Server
DNS means Domain Name services.

39.  Mail Server :

46.  FTP Server

53.  Introduce to Project:
The name of my project is Petrobangla office Building network design on cisco packet tracer and
Configuration.
In my project I configuarted six floor building networking System .Here mainly focus smarter
Way for decorate officeroom . The building and the office rooms made totally Smart on
IoT devices base .Here we can callthe office as digital office.
 Using Hardwares :
In my project I used the below hardwares ,
1.Router
2.Switch
3.Server (mail ,web, DHCP, DNS, IoT)
4.Access Point
5.PC
6.Laptop
7.SmartPhone
8.Printer
9.IoT Devices
10. Network Cables
 Introduce of using Hardware’s :
Switch
A switch is a hardware device that connects multiple devices on a computer network. A
Switch contains more advanced features than Hub. The Switch contains the updated
table that decides where the data is transmitted or not. Switch delivers the message to
the correct destination based on the physical address present in the incoming message.
A Switch does not broadcast the message to the entire network like the Hub. It
determines the device to whom the message is to be transmitted. Therefore, we can
say that switch provides a direct connection between the source and destination. It
increases the speed of the network.

54. Router
A router is a hardware device which is used to connect a LAN with an internet
connection. It is used to receive, analyze and forward the incoming packets to
another network. A router works in a Layer 3 (Network layer) of the OSI Reference model. A router
forwards the packet based on the information available in the routing
table. It determines the best path from the available paths for the transmission of the
packet.
Server
A server is a computer program or device that provides a service to another computer program and its
user, also known as the client. In a data center, the physical computer that a server program runs on is also
frequently referred to as a server. In the client/server programming model, a server program awaits and
fulfills requests from client programs, which might be running in the same or other computers. A given
application in a computer might function as a client with requests for services from other programs and as
a server of requests from other programs.
I have used five types of server that are,
Mail server : A mail server (sometimes also referred to an e-mail server) is a server that handles and
delivers e-mail over a network, usually over the Internet. A mail server can receive e-mails from client
computers and deliver them to other mail servers.
DNS Server : The Domain Name System (DNS) is the phonebook of the Internet. When usertype
domain name such as ‘gogle.com or anything.com into the web browser,DNS is responsible for finding
the correct IP address.
DHCP Server : Dynamic Host Configuration Protocol (DHCP) is a client/server protocol that
automatically provides an Internet Protocol (IP) host with its IP address and other related configuration
information such as the subnet mask and default gateway.
WEB Server : A web server stores and delivers the content for a website – such as text, images, video,
and application data – to clients that request it.
IoT Server : IoT Data Server is a "Data Integration Controller" consisting of high reliable industrial
computer and non-programming data integration software.
Access Point
An access point is a device that creates a wireless local area network, or WLAN, usually in an office or
large building .

55. PC
A personal computer (pc) which use as end devices in a network system.
Laptop
A laptop is also used as end devices for network system.
Printers
It is also used as end devices for network system. It’s connect via connecting device.
Smart phone
Smart phone is a smart device. It is a wireless device as well. It connect wirelessly and also cand control
IoT devices.
IoT Devices
Internet of things( IoT )are basically smart devices which have support for internet connectivity and are
able to interact with the other devices over the network.
Network Cables
Network cables are used to connect and transfer data and information between computers, routers,
switches and storage area networks .

56.  Projectdetails :
This is the view of the TOP floor of my project
Here , three rooms one is for chairman and the second one for director and the third one is the
server room or admin control room. I have used five server. In the chairman room there are three
end devices connect a switch. A access point for wirelessly connect some IoT device. Here think
about the digitalization for designing every floor. That make the office building a smart office.
It is main router(router 4th
) .which is directly connect on internet. The IP of this router is the default
gateway for all the devices in the building.

57. This lapto is from the Director room. Here Default gateway is same as main router IP.
The Domain Name Services server config snap.

58. This is IoT admin server .Which work as remote server for all IoT devices. IT is the life for all IoT
devices as well.

59. Here IoT devices is controlling by login the server site with username and password.
 4th
floor
This is the fourth floor. Here has Two Office room . In every floor I have used smoke detector and siren.
Incase anyhow building affected by fire then the fire siren will ringing .
In my project I mainly focused on STAR topology . I preferd on STAR topology because ,
Fast performance with low network traffic. Easy to troubleshoot. Easy to setup and modify.
Only that node is affected which has failed, rest of the nodes can work smoothly.

60.  3rd
floor
This is the third floor .Here the Genarel Manger room situated and a one room corporate office.
 2nd
floor
This is the second floor. Here the conference room and the Deputy manager room and a office room also.
 1st
floor

61. This Is the first floor .Here has prayer zone and information desk and a waiting room .
 Ground floor
This is the ground floor .Here has parking zone.
In every floor have a main switch. In all devices connecting this switch directly or via other switches.
Every floor main switch is connect to the mother main main switch which is situated in the top floor and
directly connect to the main router. Thus the networking procedure running on following project.
 Total cost (tk) value of this project:
I have already mention in the top portion of this report for using hardware. So the unique price of a
Switch is 1861 Tk . The unique price of Router is 27919 Tk . The Access point Unique price is
9557 Tk. The server unique price is 270651 Tk .Every PC contains the price in 34000 Tk and the Laptop
unique price is 58590 Tk .The smarthphone unique price is 28990 Tk .The printers unique price is
13500 Tk . The Air condition unique price is 47550 Tk . The celling Fan price is 2700 Tk. The web
camera unique price is 3850 Tk. The smoke detector and siren price uniquely 7000 Tk .The price of serial
DCE cable 1116.44 Tk .The copper cross cable price 11500 Tk and the copper straight cable price is also
11500 Tk. The configuration cost is 20000 Tk .
