Yes, i also agree that NVO3 charter should clearly include the description for multicast traffic handling. It is an important part in NVO3 solution.

Many data centers fall into this category. I don't particularly like the phrase "application specific multicast", [Linda] It is about the non ARP/ND related multicast (or the multicast initiated by clients). [ag] Perhaps we can refer to this as "multicast applications other than ARP/ND." but I think I understand what you mean by it. And I agree with your statement that it's an important area for the WG to address. I also think that multicast traffic can be taken into account when documenting the data and control plane protocols already enumerated in the milestones. It isn't clear to me that there is any reason to call it out specifically, nor what such a milestone would look like. [Linda] The entire charter didn't even mention application initiated multicast. It is wrong. NVA can eliminate (or reduce) ARP/ND related broadcast/multicast, but not application initiated multicast. The current proposed MILESTONES have separate deliverables for WG adoption and FOR IESG review, and very detailed categories being explicitly spelled out. Therefore, at minimum, should have one line on the protocols to handle hosts/applications initiated multicast. [ag] I agree with Linda here. While it sounds like there is agreement that the problem needs to be addressed by the working group, it would be useful to at least have an explicit mention of multicast somewhere in the charter. Perhaps we could change the following line from: "The NVO3 WG will develop solutions for network virtualization based on the following architectural tenets:" to: "The NVO3 WG will develop solutions for network virtualization covering both unicast and multicast traffic handling based on the following architectural tenets:" Anoop
