07 - Network topologies

The most used topologies:

• Ring/1D Torus
  • the usual ring one
• Mesh
  • “maglia”
• Torus
  • mesh+ edges
• Trees
• Fat trees
  • like a three but we have more links on the roots
• Blocking fat trees
  • same as fat trees but while going from roots to leafs, we reduce bandwidth
  • 
• Dragonfly
  • fully connected groups of switches
  • groups are fully connected between them
• Dragonfly+
  • same as dragonfly, but switches are connected with a fat tree
• Slimfly
• Jellyfish
  • Let’s drop any structure and use a random graph
• HammingMesh
  • many configuration linked each other
• RDCNs
  • Reconfigurable Data Center Networks
