Mesh networks and dynamic routing

As previously mentioned, a link-layer protocol may be able to implement mesh-under mechanisms, which hide the complexity of the topology for the upper layers. A different approach is applied when the link-layer protocol does not implement this feature, or whenever the mesh solution may be extended across different network interfaces, and thus must implement a standard protocol that is interface-agnostic. Each link connects two devices in direct visibility, which in turn coordinates to detect the optimal network path to reach a remote node, based on the detected topology. Intermediate nodes along the path are configured to route the traffic toward the destination, based on the information available on the ...
