1. Mesh Topology
A mesh topology is a network configuration where devices (nodes) are interconnected, allowing for multiple data paths between nodes. This design ensures redundancy and reliability, as data can be rerouted through alternative paths if one connection fails. Mesh topology is often used in scenarios demanding high availability and fault tolerance.
Characteristics
- Full Mesh:
Every node is connected directly to every other node. Offers maximum redundancy and fault tolerance. Example: A small data center with critical systems may use full mesh for uninterrupted connectivity.

- Partial Mesh:
Only some nodes are directly connected, while others rely on intermediary connections. Balances cost and redundancy by prioritizing critical nodes for direct links. Example: A city’s public Wi-Fi network where main access points are fully meshed, and secondary nodes rely on them.
