A hyper tree is an acyclic hyper graph.
Tree and hyper tree networks are important special cases of star network topologies.
A Tree Network consists of star-configured nodes connected to switches/concentrators, each connected to a linear bus backbone. Each hub/concentrator rebroadcasts all transmissions received from any peripheral node to all peripheral nodes on the network, sometimes including the originating node. All peripheral nodes may thus communicate with all others by transmitting to, and receiving from, the central node only. The failure of a transmission line linking any peripheral node to the central node will result in the isolation of that peripheral node from all others, but the rest of the systems will be unaffected.
