Hi Alper, Is there any essential difference between placing the mobility function closer to the user and placing the mobility function closer to the CN? I think in some sense the user host and it's corresponding node are the same for mobility management protocol. So what's the reason to distin

Hello folks,One difference is that a mobile node is likely to be located in a network that supports mobility, whereas the network hosting a general CN may not have any mobility support features.Regards,Charlie P.-Original Message- From: Weixinpeng Sent: Mar 17, 2014 11:59 PM To: Alper Yegi

Hi, Mobility issues are not specifically in MIF scope. So, as long as we are talking about exposing mobility state, the I-D should be in DMM. Another reason is that MIF is still discussing the generic MIF API, so, I'm not sure they can go on the mobility area before a while. Pierrick >-M

Hello Xinpeng, In the legacy thinking, the mobility anchor is in the core network (centrally-located HA). That's the basic Mobile IP design. Now people are also considering placing anchors in the access network. And then there's one more possibility, which is to place an anchor near/on the corre

Hello, Distributing mobility anchors closer either to the MN or CN are both valid scenarios. But, maybe there are other optimal anchor location; actually, here, we are seeking to reach optimal routing by placing the anchor closer to the optimal data path. Also, we may also want to keep a centra

I realize that I gave a very bad example of centralized control functions... In our context, we should rather talk about centralized mobility control function (with distributed DP function)... anyway, my proposal for text revision is still valid. De : dmm [mailto:dmm-boun...@ietf.org] De la par

Hello Pierrick, by stating that the MAPs are closer to the optimal data path, we are advocating that the signaling should be in-band. MAPs work on the control plane. Is there a reason for this? Also, I do not understand why we need to make a distinction between "user" and CN. The distinctio

Hi Pirrick, I agree with you that the anchoring location considerations should be more generic. But for your suggested NEW TEXT, I think it's a bit of ambiguous to say "closer to the optimal data path", and as my understanding what DMM is trying to do is to eliminate sub-optimal routing path betw
