What defines a mesh network topology?

A mesh network topology is characterized by devices connecting directly to multiple other devices. This arrangement allows for numerous pathways for data to travel between devices, creating a resilient and reliable network structure. In a true mesh configuration, each device can communicate with any other device within the network without relying on a central hub or switch. This means that if one connection fails, there are alternative routes available for data transmission, enhancing fault tolerance and minimizing the risk of a single point of failure.

In contrast, a configuration where all devices are connected to a single hub does not represent a mesh network but rather a star topology. A linear connection of devices refers to a bus topology, which is limited in its paths and can suffer from network degradation as more devices are added. Finally, using a star configuration fails to embody the fundamental principle of a mesh setup, where multiple interconnections among devices are paramount for robustness and redundancy.
