Proposed Network Topology and Design

-

 

Network Devices

1.      Internet Modem / ONT (from ISP)

a.       Connects the café network to the ISP.

2.      Router

a.       Manages internet traffic

b.      Provides Network Address Translation (NAT)

c.       Acts as a firewall for basic security

d.      Distributes IP addresses via DHCP

3.      Network Switch (24-port)

a.       Central connection point for all wired computers

b.      Allows fast data transfer within the LAN

4.      Customer PCs

a.       Connected via Ethernet cables to the switch

5.      Admin PC

a.       For monitoring, billing and management

6.      Wireless Access Point

a.       Provides Wi-Fi access for staff or limited customer use.

Network Topology

Proposed network topology: Star Topology.

  1. All computers connect to a central switch, making troubleshooting easier
  2. If one cable or PC fails, the rest of the network remains unaffected
  3. High performance as no data collision occurs.


Network Topology Diagram

Communication Media

1.      UTP Ethernet Cable (Cat6)

a.       Connects PCs, switch and router

2.      Fiber Optic Cable (ISP side)

a.       For ISP to deliver high speed internet to the premise

  IP Addressing (Subnetting) This cyber cafe network uses a private IP addressing scheme to ensure secure and efficient communication between all network devices. A suitable IP address is selected to support all computers, servers and networking devices used in the cyber cafe.    NETWORK REQUIREMENT The cyber cafe requires the following devices: 10 client computers 1 server 1 printer 1 router  1 administrator PC  Total number of hosts required is 23 devices.   Subnetting Calculation        The selected IP address is 192.168.10.0/24 which is suitable for a small business network.   IP Address: 192.168.10.0  Subnet Mask :  255.255.255.0  Prefix Length : /24  Total IP Addresses : 256  Usable Host Addresses : 254  Since the number of hosts required is less than 254, only one subnet is needed and no further subnetting is required         IP Ad dress Details   Network ...
