Hi Dave, Many thanks for your comments. Inline with PC.
Cheers, Pablo. -----Original Message----- From: dmm <[email protected]> On Behalf Of David Allan I Sent: viernes, 23 de julio de 2021 19:51 To: [email protected] Subject: Re: [DMM] 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 [PC] Do you think there is any new mechanism to be added to the currently defined ones? - 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) [PC] User Plane Message encoding is out of the scope of this draft. However, draft-murakami-dmm-user-plane-message-encoding-03 proposes a mechanism to encode the Echo Request, Echo Reply, Error Indication, and End Marker. - 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" [PC] Excellent point. Seems we missed this one in draft-murakami! We can add in there the QoS Monitoring Packet indicator, as well as the encoding for the timestamps and average DL/UL delays. - support for paging policy presence/indication [PC] Same as previous. Many thanks. [PC], By the way, I've posted an updated revision as the reference to draft-murakami was missing. If this has come up elsewhere, let me know Cheers Dave _______________________________________________ dmm mailing list [email protected] https://www.ietf.org/mailman/listinfo/dmm _______________________________________________ dmm mailing list [email protected] https://www.ietf.org/mailman/listinfo/dmm
