"Also called mesh topology or a mesh network, mesh is a network topology in which devices are connected with many redundant interconnections between network nodes. In a true mesh topology every node has a connection to every other node in the network. Full mesh topology occurs when every node has a circuit connecting it to every other node in a network. Full mesh is very expensive to implement but yields the greatest amount of redundancy, so in the event that one of those nodes fails, network traffic can be directed to any of the other nodes. Full mesh is usually reserved for backbone networks.

Partial mesh topology is less expensive to implement and yields less redundancy than full mesh topology. With partial mesh, some nodes are organized in a full mesh scheme but others are only connected to one or two in the network. Partial mesh topology is commonly found in peripheral networks connected to a full meshed backbone. "

Smart Computing

"A type of network architecture. Mesh provides redundancy, or alternate data paths, to prevent an entire network from crashing if one of its nodes is unreachable. A mesh network connects each node to several other nodes. If, for some reason, data cannot reach a node (due to a cut line or just a down node), it can be rerouted through other nodes to reach its destination. The more connections between nodes, the more redundancy increases and the more reliable the network is. Unfortunately, more redundant networks are also more expensive."
