Hi, While it is still complaining with error message that it wants openflow version 1.0, I think you only get to download older version of openflow by following the manual. ( ie. wget http://noxrepo.org/openflow_mod.ko) The reason we are trying building this test network (instead of Mininet) is that we need to test out a wireless connection. Do you know if Mininet supports wireless network? If not, could you suggest other alternative way for building test network that simulates wireless network? Thanks in advance. Brian Baek
