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
$ sudo mn --custom dcfat.py --topo fat --controller remote $ ./pox/pox.py samples.spanning_tree
- check with ping
