So it turns out that the SDN OpenFlow tutorial has turned into a bit if a thing. While it was going to use mainly VMs and simulators, Citylink has supplied 20 mikrotik routerboards for the class to actually configure into an openflow controlled data plane. On ya guys, much appreciated, great NZNOG and SDN supporters as always. What I'm after now however is the around 60 Ethernet cables to hook it all together. If anyone could help me out so that I don't need to buy them that would be awesome. Yes you get then back afterwards. Thanks heaps. It should be an awesome tut. Dean
