Step-by-step create LAN :
1. Determine the network topology: Based on the specification, the network topology for the LAN will
be a star topology with a switch at the center connecting all the devices.
2. Identify the network devices: The network devices needed for the LAN will include switches,
routers.
3. Plan the network addressing scheme: The addressing scheme for the LAN will be based on IP
version 4 with a Class C range of 192.168.1.0/24.
4. Identify the network security requirements: The LAN will require basic security measures such as
firewalls, antivirus software, and user authentication.
5. Plan the network bandwidth: The network bandwidth requirements will be based on the number of
users and devices and will be calculated using network performance analysis tools.
6. Develop the network blueprint: A blueprint of the proposed LAN should be developed to provide a
clear diagram of the network topology, device placement, and connectivity.
7. Select the appropriate devices for the LAN: Based on the specification of the project, the network
devices chosen for implementation will include Cisco Catalyst switches and Cisco routers.
8. Configure the network devices: Configure the network devices to implement the desired network
topology, addressing scheme, security requirements, and network bandwidth.
9. Test the network: Test the LAN to ensure that it meets the required bandwidth and cost constraints
as per user specifications.
10. Maintain the network: Design a maintenance schedule to support the networked system and
ensure that it is regularly updated and optimized to provide reliable and efficient performance.
Justification of Device Selection:
The chosen devices are from Cisco, a well-known and reliable brand in the networking industry. The
Cisco Catalyst switches are selected to provide high-performance, callable, and secure access for the
LAN. The Cisco routers will be used to provide connectivity between the LAN and other networks. The
use of Cisco network devices will ensure that the LAN is secure and efficient, while also ensuring
compatibility and reliability.
Test Plan:
The network will be tested to evaluate its ability to meet the requirements of bandwidth and cost
constraints as per user specifications. The test plan will include network load testing, network
performance analysis, latency testing, and packet loss testing.
Security Requirements and Quality of Services:
The LAN will require basic security measures such as firewalls and antivirus software, as well as user
authentication to prevent unauthorized access to the network. Quality of services (QoS) will be
implemented to prioritize network traffic and ensure that high-priority traffic is given priority over
lower-priority traffic.
Maintenance Schedule:
A maintenance schedule will be put in place to support the networked system. Regular maintenance
activities will include regular software updates, firmware updates, and hardware maintenance.
Network performance analysis will also be conducted regularly to identify and address any issues that
may arise. Additionally, the scheduled maintenance will include regular backups and security checks
to ensure the safety and security of the networked system.
Explanation:
The router will act as the gateway for all devices on the LAN, providing access to the internet. The
switch will connect all devices together and allow them to communicate with each other. Each device
will be assigned a unique IP address within the 192.168.1.x subnet with a subnet mask of
255.255.255.0, allowing for up to 254 devices on the network. The default gateway for all devices will
be set to the IP address of the router, allowing them to access the internet. The printers will also be
assigned IP addresses within the same subnet and will be accessible by all computers on the network.
