Re: Additional questions/comments on draft-ietf-dmm-srv6-mobile-uplane-13

Hi:

Looking over this draft it strikes me that IF you are discussing a GTP replacement, there are a few unaddressed gaps...or at least I see no mention of them.

-  adding X2 to the list of interfaces to be supported
-  support for end-marker for handoff stream synchronization (probably could fit the unused bit in Args.Mob.Session but frankly I have not studied this in detail)
-  support for QMP (quality measurement protocol), which I believe needs to also extend across the radio interface so is not simply local to the GTP domain and can be "stunt doubled"
-  support for paging policy presence/indication

If this has come up elsewhere, let me know

Cheers
Dave
