mesh topology
termnetworking
Nodes connect to many other nodes directly, so traffic has multiple independent paths.
A full mesh connects every node to every other, which costs n(n-1)/2 links and stops scaling almost immediately, so real designs use partial mesh: rich connectivity where it pays, sparse elsewhere. The internet's inter-AS core is the largest working example, and wireless mesh applies the same idea where cabling is impractical. Redundancy is the point, and the price is complexity in routing and troubleshooting.
