Hello Fred

Thanks for the new pointers.

I really need to dig more to understand the whole AERO story. I’m a bit confused at the moment if omni tunnels and how, how that compares to say, MONAMI MCoA (https://tools.ietf.org/html/draft-ietf-monami6-multiplecoa-14). But that’s another thread.

At the end of the day, my draft is supposed to be agnostic to the way the address is formed. So the AERO approach should be represented too, mostly if it is well on the way to std track. Just that I cannot write that text at my current level of understanding. So if you are interested in having the AERO/OMNI approach discussed in the draft, you’ll have to take the pen again…

Take care,

Pascal

Pascal, while it is true that OMNI and AERO do conform to overlay principles, on
the access network proper the OMNI interface uses unencapsulated IPv6 ND
messages in a manner that achieves what your draft is asking except in a
different way. Your draft seems to be asking for a “get a care-of address from
infrastructure” approach, whereas OMNI is “bring your own address”.

BTW, the correct URLs were given in an earlier message but here they are again:

https://datatracker.ietf.org/doc/draft-templin-6man-omni-interface/
https://datatracker.ietf.org/doc/draft-templin-intarea-6706bis/

Note that the current OMNI draft includes “6man” in the name, and that RFC6706
is to be obsoleted by the (bis) named above.

Thanks - Fred

Hello Fred

I do not see why we’d need to wait for AERO to be RFC to adopt this draft.

Still, applying overlays on wireless is certainly useful, there’s AERO, and there’s also RAW. So I agree with you that discussing only MIP / NEMO is not sufficient. But hey, this is not WG LC, just adoption.

I’d be happy to extend the scope to accommodate a section on AERO if that is what you have in mind and what the WG wants. As I’d be inclined to discuss more on RAW. But I’d need your help for that text, and we’d have to present those things as more advanced / WIP activities.

Keep safe,

Pascal

I don’t think it is time for this yet. The document calls for multilink subnets,
care-of addresses and Mobile IP whereas AERO and OMNI do not. There
is a point to be made that Pascal’s doc considers multihop primarily whereas
AERO/OMNI consider multiple links primarily. But, I think it would be a pretty
simple extension to get AERO/OMNI to do multihop using your favorite
choice of MANET or other technology.

Thanks - Fred

Pascal

I agree that this is an important topic that 6MAN should take up.

As for draft name I agree with standards track and the name shown in the subject heading
draft-thubert-6man-ipv6-over-wireless-06 is good.


You maybe familiar with an inherent issue that exist with multicast over WiFi where the multicast packets are transmitted at the lowest connection speed of all hosts associated to an SSID and thus the connection bandwidth ends up being low.  Dual band 5G with 802.11ac does help as devices not supporting AC cannot connect and have to connect to the single band SSID.  However older devices on single band still are subject to the significant step down to the lowest speed..

Since IPV6 uses multicast for ND, all ND packets automatically get throttled and stepped down to the lowest bandwidth of all connected devices.  This step down issue exists for IPv4 multicast packets, however I have not tried with IPv6 but i am guessing the issue does exist.

There are WIFI vendor implementation that exist to circumvent the step down issue by taking incoming multicast steam and unicast out to all WiFi clients.  Drawback is bandwidth consumption with unicast over shared WIFI channel.

Hi Pascal,

I suggest changing the draft name from draft-thubert-6man-ipv6-over-wireless
to draft-thubert-6man-ipv6nd-over-wireless

Dear all

I applied the changes proposed by Carsten and held the change to informational status for now, per the latest with Brian.
Many thanks to both of you!
