Hi Pete, This obviously wouldn't work for billions of MNs. But, with DMM people are starting to realize that MNs don't need completely stable global addresses that live forever. Most don't, but some do. We need to account for them as well. So I think DMM should focus on localized

Hi Pete, My definition of CP is between the AG and the MA, what is out there today. Now, if there is a functional split of CP and DP on any entity, and if there is a interface between those two in the form of some CP interface, then I don't have a term for that interface. We can probably agree

Rather than sink into a re-chartering discussion, I would like the WG to focus on completing the existing work items. It was suggested that an interim (or 2) get set up to work on these items. Please focus on this rather than re-chartering. Regards, Your friendly AD On 11/13/13 3:43 PM, Behcet

Hi Brian, I personally think that Interim(s) would not work for dmm. Only a few people could go to such meetings. Most of us already have a heavy travel schedule, squeezing another trip seems not so reasonable. Regards, Behcet On Wed, Nov 13, 2013 at 2:53 PM, Brian Haberman

Hi Marco, My intention is not to eliminate a tunnel that exists in any of the tunnel management protocols (aka MIP6, PMIP6, ..). My picture of DMM primarily distributes topological anchor point for the MN's IP address(es). Forget about the C-plane for now. Tunnels apply solely below (well,

Hi, Alex, When it comes to injecting routes into the routing infrastructure, I think we have to use the proxy model. It doesn't make sense for the MN to be speaking to the access network's routing protocol. This means the MAG will need to authenticate the MN and check that the IP addresses
