What is Mesh Topology? What are the Advantages and Disadvantages?
In computer networking, a mesh topology is a network in which each node is connected to every other node, forming a fully connected network. This means that each node can communicate directly with every other node without the need for an intermediate node to relay the message.
Advantages:
- Reliability: Each node is connected to every other node, so if one node fails, the other nodes can still communicate with each other.
- Fault tolerance: If one link between two nodes fails, the messages can be rerouted through other nodes, ensuring that communication is maintained.
- Scalability: Mesh topologies can be easily scaled up by adding more nodes, making them suitable for large networks.
Disadvantages:
- Cost: Installing and maintaining a mesh topology can be expensive, as it requires a large number of networking cables and equipment.
- Complexity: Managing a mesh topology can be complex, as each node must have information about every other node in the network.
- Latency: The latency in a mesh topology can be higher than in other topologies, as messages have to travel through multiple nodes to reach their destination.
