WebSep 20, 2024 · The fat tree is a special case of the Clos network. The three-tier Clos network is transformed into a two-tier leaf-spine network after folding. Leaf switches or leaf edge switches/routers can be used to access external networks and other data centers. WebInterconnection networks based on the fat-tree topology are widely used in high-performance parallel supercomputers. In a classical fat-tree, the radix of root switches is less than that of other switches. Fat-tree is a folded version of a Clos network. A Clos network uses the same radix switches in all stages. However, fat-tree or Clos network …

Web2.1 Clos-based Networks Fat-tree. Fat-tree was proposed in [1]. Fat-tree has three switch layers which are called spine, aggregation, and TOR (Top Of Rack) layers from top to bottom, respectively. All the switches have the same port number, n(an even num-ber). Each TOR switch uses n 2 ports to connect n 2 servers, and the rest n 2 ports to ...
