6 Monitoring and Maintenance:
Regularly monitor the network for any issues, such as cable faults or device failures. Ring topologies are known
for their fault tolerance, but it’s still important to address any problems promptly to maintain network performance.

Use Cases:
Ring topologies are well-suited for certain scenarios, such as:
• Fiber Optic Networks: Fiber optic rings are commonly used for high-speed, long-distance data transmission
due to their reliability and fault tolerance.

• Industrial Control Systems: Ring topologies are used in industrial environments where continuous operation
is critical, as they can provide redundancy and fault tolerance.
• Token Ring Networks: Token ring networks, a specific type of ring topology, were once popular in early
LANs, though they have largely been replaced by Ethernet networks.
4 Mesh Topology - Mesh topology involves connecting each device to every other device in the network.
• It provides high redundancy and fault tolerance as multiple paths exist for data transmission.

• However, it can be complicated to implement and requires more cabling and resources.

Scenario: Imagine you’re tasked with designing a computer network for a medium-sized company that requires
a high level of reliability and redundancy. You decide to implement a mesh network topology to ensure seamless
communication even if some network links or devices fail.
Here’s how you can use a mesh topology for this network:
• Identify the Devices: First, identify all the devices that need to be connected in the network. These may
include computers, servers, printers, and network switches.
• Calculate the Number of Connections: In a full mesh topology, every device connects to every other device.
To calculate the number of connections needed, you can use the formula:

Number of connections = (n * (n - 1)) / 2
Where ‘n’ is the number of devices. This will give you the total number of connections required.
• Install Network Cables: Physically install network cables to connect each device to every other device in the
network. Use appropriate networking hardware like switches or routers to facilitate these connections.
• Configure Network Devices: Configure the network devices (switches and routers) to enable communication
between all devices. Set up routing tables and ensure that data can flow through multiple paths, providing
redundancy.
