I installed Pox, flowvisor and mininet on my laptop.
I just want to create the
virtual openflow networks with mininet and then
connected the switches to the
Flowvisor, also, I want to connect the pox
controllers to the flowvisor.
I start with the mininet and typed:
sudo mn --controller=remote,ip=127.0.0.1,port=6633;
and it displays
sudo mn --controller=remote,ip=127.0.0.1,port=6633
*** Creating network
*** Adding controller
Unable to contact the remote controller at 127.0.0.1:6633
*** Adding hosts:

*** Adding switches:

*** Adding links:

*** Configuring hosts

*** Starting controller

*** Starting CLI:

then I try to start the flowvisor /usr/local/sbin/flowvisor
and it responds:
troy@troy-Rev-1-0:~$ /usr/local/sbin/flowvisor

Could you tell me why I failed, and how can I connect
the mininet switches to
the flowvisor and the Pox.
Thanks a lot ^^
