AFAIK openflow is suitable for datacenters, but doesn't scale well for users termination purposes.I have considered OpenFlow and might do that. We have OpenFlow capable switches and I may be able to offload the work to the switch hardware. But I also consider this solution harder to get right than the idea of using Linux with tap devices. Also it appears the Openvswitch implements a different flavour of OpenFlow than the hardware switch (the hardware is limited to some fixed tables that Broadcom made up), so I might not be able to start with the software and then move on to hardware.
You will run out from TCAM much sooner than you expect.Linux tap device has very high overhead, it suits no more than working as some hotspot gateway for 100s of users.
