Fat Tree

Fat Tree refers to a network topology used mainly in the field of computer clusters. Derived is this topology of a binary tree, but offer the Fat - Tree topology, is closer to the root lines a higher bandwidth. This is characterized by thicker compounds in the picture.

In addition, one can see that the meshing on the second level is denser than in the last layer to the nodes. The advantage is that the communication between the hanging on the 1st and 3rd switch the lowest level node does not have to walk right up to the root switch. So Fat Tree offers a high bisection bandwidth.

The High Performance Computing at accumulating enormous depending on the application network load can be handled well.
