- Mesh topology is a network configuration where each device is connected to every other device, forming a web-like structure. This configuration offers multiple data pathways, ensuring that data can still be transmitted even if one route is disrupted, thereby providing redundancy and fault tolerance.
- This novel network architecture establishes point-to-point connections between the network’s devices by connecting every computer to every alternate computer. In a mesh network, messages can take multiple routes to reach their destination, offering flexible and adaptive pathways that differ from the more structured approaches of previous topologies.
- A full mesh network is one in which every device is connected to every other device. One drawback of mesh networks with n nodes is that each node needs n-1 I/O ports, or links, and a mesh network with n nodes needs n(n-1)/2 links.
