I think the idea was slightly different. We were equating a vif to NIC in a physical server. A port was equated to a switch port on a physical switch. Doesn't necessarily mean they have to be different. But, there was a reason we used different terminology.

</div>
<div>In particular, we felt the vif was something that would continue to be in the server's domain and managed within Nova. A port was a construct that is owned and managed by the network service (Quantum).
