Exercise I: Data Centers

  • (30P) Warmup (simple Tree) ($ => commands on VM, > => commands on mininet/pox, Q => Question)
  $ sudo mn --topo tree,3 --mac --arp --switch ovsk --controller remote
  $ h1 ping h8 
    • (Q: What do you observe?)
  $ ./pox/pox.py
  $ h1 ping h8 
    • (Q: What do you observe?)
  $ ./pox/pox.py samples.spanning_tree 
  $ h1 ping h8 
    • (Q: What do you observe?)
  • (40P) Create your own simple tree (binary, i.e. each node will connect to two nodes below it)
    • copy dcsimple.py ([1]) to mininet/custom/
    • modify dcsimple.py to create hosts, switches and connections for a three level tree
  $ sudo mn --custom dcsimple.py --topo simple
    • Check with ping
  • (30P) Create your own Fattree
    • copy dcfat.py ([2]) to mininet/custom/
    • modify dcfat.py to create a fat tree (level 0: so & s1, level 1: s2 & s3, level 2: s4, s5, s6, s7, Level 3: Hosts)
  $ sudo mn --custom dcfat.py --topo fat
    • check with ping
