Thomas, See below. I do not agree to the wording.
And I suggest to change the definition of tenant system, which I identified as being perhaps a root cause of confusion.

Some tenant systems > will have more than one physical NIC. Agreed. Lothar: Disagree - Given the current definition of tenant system, one would have to make a case differentiation throughout the document as follows: Case A: Tenant System is a VM - In this case - which may be the most important one to many - above statement is wrong, because then the tenant system has zero physical NICs. Case B: Tenant System is a bare metal server - In this case above statement is true Case C: Tenant System is "according to current definition" a router or firewall... - in this case we start referring to router ports as NICs or pNICs, which may further increase confusion. > We may describe some typical tenant systems as part of examining use > cases, but NVO3 should define behavior in terms of the network > interface, i.e. TSI, behavior and should not restrict tenant system > architecture. Another way of looking at it is that the TSI is an attachement point/interface to the TS. The point where the TSI attaches to the TS has two sides. On the tenant facing side, it appears to be a NIC. It looks like a NIC, behaves like a NIC, etc. On the side facing away from the tenant (e.g., the hypervisor in the case of a virtualized system) we call it a TSI. The TSI side will have attributes that are specific to NVO3. Does that make sense?
