Hi all, The current version looks fine. I just have some minor comments as follows:
1. In section 6, it said “ It is believed that overlay-based approaches may be able to reduce the overall amount of flooding and other multicast and broadcast related traffic (e.g, ARP and ND) currently experienced within current data centers with a large flat L2 network. Further analysis is needed to characterize expected improvements. ” IMHO, the above statement is not correct since this is irrelevant to whether the virtualized network is overlay-based or not. 2. It seems that this problem statement draft did some additional work which the framework and the requirement drafts should do. For example, it talks about the three possible work areas in the control plane, would it be better to move this part to the framework and control-plane-requirement docs?
