A

Before we start.

B

A

A couple moments, so we need a diverse crowd when I'm in a table, so any volunteers or back.

A

In case it comes today is probably gonna be a short meeting, so when the bus turns you can go to take a minutes. So next time we skip me and if this thing will be repeated.

A

Remember the five minutes.

C

A

A

Viscosity miracle.

A

Ensuring that six months happy with it and as I mention.

A

A few time won't be enough for some. Neither the first Illumina have a very good idea of how the second dopamine would look like. We may assume they're talking discussion, not honest, so hello, Quinn, Pro, presents a second document is really important for the press statement welcoming to vini be the basis starting point for the resulting discussion. He doesn't make sense to have resulting discussion that is not backed up over and over.

A

Given by the government for the sake of punishing so keep that in mind and with that, we can just go to the first item over again, where a second sorry 20 married so go to the toy store bashing of.

A

This carbon arrows presenting on behalf of Alex and Russell Crowe and people here show and just presenting with it. So you have any detailed question. I may not be able to progress.

A

So this is the kingdom of.

A

Kind of issues on top of issues of comments.

A

So you remember that was our discussion in there. Whether the viewers have girls need to be used.

A

We should talk about submissively. Now is a must, so the document says that the IP packets or LCD has to be must be transmitted over possibly using the keywords, live effects. So that's the resolution that was taken after what a long discussion and there you have the current text that isn't on the document. So this one thing that was decided and I think that's much discussion on this point at which, at this point learn there were some clarifications into the internet'll of tissue layer.

A

So another text that is on the graph basically says trying to be more clear and much simpler to simplify the application. For me, interface between the operating system and the 11:07 media device, drivers may may implement an Internet application layer that translates efinitely frames to D 1301 format and visa versa, and there's actually a description of this. Certain interpretation in Section.

A

Then the motion text changes on the enable discovery, so the mutex were basically if I find the point of the operation. Novel discovery over CB is not an opening, but it's basically I said that it's probably is is using in the document.

A

There were some comments from the six-month review. Is my body works or not? So this one may your point of we need to address basically I feel as I mentioned before. There is also a difference from perception of what the goals of the document document is. I, guess that for six men, maybe for expected piece to work in any potential.

A

Environment and with more like simple situation by so that's that's something I wanted to clarify.

D

D

We agree that in these changes, but it will be a goose egg up scoop of this document and well not touch any of these aspects. With this.

A

Kind of the scope of the document, a ambition of a theme up, I, indeed of fashion opinion upon discovery in working, really work on this used to be who worked in Japan. And if he met the shape of this document, which is by the a maggot in a non limited scenario where vehicles are.

B

Not moving very fast, you know very building.

A

Somewhere still, these kind of things when you are traveling name on discovery are cities just works, so I will now what's the best way of running left in the document, whereas I peanuts with the attachment to say, and basically what you are saying as well right right. This nope addressed new things on.

D

In be just works, it works is very subjective.

D

Absolutely doesn't make sense, you know.

A

Fine will apply so you say that passing work. They also say that the in certain s scenario, what they are.

E

Highway and has got a very narrow window words. A roadside devices is within radio range and I one possible way. The working group could move forward is to say that that one case where the traditional doesn't work is for future study and be done, but.

D

My response to that would be like who is a soft case of three I, wouldn't cut out and say that you know two vehicles are maybe going same speed. Maybe only works for partial period of time. That is, that is not practical. If I am using an application, I want the application to work consistently. I am going from San Jose to San. Francisco I want that for entire right.

D

Not because you know maybe my neighbor car is going only for how many does maybe it that speak it nd was later after that are angry, doesn't work so poor. In some case of three mean it is all three, please is a live environment because it's yeah, it's a static environment, so wait.

E

A minute I think what you just said under contradicts, which you said earlier so since I think that I probably misunderstood something. You said your earlier proposal was to just delete the paragraph right.

D

Significant community.

E

Your paragraph, your eat earlier suggestion was to just delete the paragraph and say nothing about yeah.

D

Exactly say that it's.

E

D

Go do nobody can scale, but.

E

Then you went on to say just now, but without some solution to the neighbor discovery, it isn't going to just work so I'm trying to understand what which.

D

My recommendation is in this document: let's not talk about ending I, think that requires some more analysis. Some more discussion, I think we need to do some work. I. Think that's my bottom line statement.

A

Okay, this is that without some nd work on the document, it's hard that we will get this pass-through, because these are about ipv6 overall CV. So how can you have a document of ipv6 over foo without at least planing? How nd will work on this? So that's why my personal opinion that we run into is code better. The ambition of this like it's ipv6 over CV, basic whatever, and then for optimized ipv6 over more dynamic scenarios. We need something else otherwise, for me, it would not make sense to have a document.

A

I say it's I'm dealing with everything but Andy, okay, so moving on or what you have somebody most opponent.

F

You know just respect with respect.

G

To Andy my name.

F

Is Sunita, chakrabarti and I'm also co-chair for six level, and if this group has at least taken and look at FC, 6750 65 67 775 that used for six no communication where it's a more optimized.

F

So maybe that's a suggestion, but I think for us for ipv6 I. Think Andy has to be there if it doesn't work at the way. This group once I think it has to be modified. I'm.

E

Sorry was that six, seven, seven, nine sorry, six.

F

775 five: yes, okay,.

A

H

Run insult just an observation: both the old text and the new text contrast evidence 11. Oh, she beat 11 links and the letter is very ambiguous.

H

What this probably meant here is infrastructure mode, ESS, a opportunity 11, but there's also such a thing as a total is 11 IBSS. Now he is a saucy. No, he or she be contrasted to a tour 2011. What.

E

Ocb is about DSRC attitude.

H

Are 11 P, it says, 802 it 11 OC b links is different than over. 82 will be 11 links whatever what 802, what the 11 makes I see that that part thank.

E

You I misunderstood your free account, so.

H

It could be easy, it could be. Ideas could be mesh mode, it has to be more specific. Okay,.

A

Buzzer coming to the office.

A

Okay, so, in the words also some changes on the slack, so basically they they updated that so the new taxes that they interpreted in the fire for now CB interfaces form using the same rules at as the interface identify for an Ethernet interface. So the recommended method for forming a stable interface identifiers is described in 1864.

A

It also said that the method of forming is described in Section 4 of 2464 may be used during transition time, so basically is trying to adapt to the current mechanisms for every six slack I. Think that's the purpose to play father there that takes up. Was there any comments on this and then some minor needs that need to be solved, but this is really within one of these, so this is basically all the author's submitted.

A

So again, what you have to address the comment from Drammen, but anyway we need to work with this and I guess we we need to back up to the the people that were comments in six month and to see what's right or in with them in a potential resolution for this, because this and discovery and discovery this.

B

A

Thin film is our showstopper for the government to to progress, so we need to see where we want the hole- and this thing to be title in this document that will delay it, because it's a lot, a lot of things to be addressed and where they will be happy with resolution, say: okay with this and a clear explanation of the scope of this document where it applies and identification on what does not work in which situations does left for future work. And let's go with that.

A

That will be my preference, my preferred approach as Josh mentioned, but we need to talk to six-month to see where they're happy Willa.

E

I'd like to repeat the call that I made on the mail list, if anyone has a implementation that is based on this internet draft and you have any experience related to the neighbor discovery- part from testing that implementation, please share it with us, either on the mail list or at the mic. Now.

A

We can now move to the second presentation.

A

Anyone that needs to sign.

G

Hello, this is our John Paul's own Hong, Kong University in Korea, I'm editor for the second hour working on a document, problem statement and use cases. So we have a lot of work closest so update last second version and saw the bulges so yesterday, I submitted birch and therefore the major updates are the first one, either the organization our table of contents.

G

So we try to focus on the problem statement and also the use cases so last tool and Amiri that our and 80s wash machine on and local chairs a skittish, especially our we tried to make our problem statement Oh, commander livable. So in the past a previous version has appeared more than 250 pages. Now you can see 20 faces just a. We focus on Berkey the work item, the IPA or a problem or statement that the first one is the neighbor discovery.

G

So just previous of the presentation and thusly I mentioned the neighbor discovery is not a simple trivial, and so we needed to dig out the second one is a mobility and management for consider.

G

Similarly, such as the handle issues, and also some related to enable this copy first on one, is our security and the privacy, so this slide shows table over a content. So you can see. The first part describes the use case.

G

Is we two three equal to I into s, and then we analyze called the protocols such as IP version 6 over at about 11, o gb level Allah, and you can see and then I specified general problems such as what is our playground, so I describe to teach you our network architecture and also addressed latency as treaty shipping handling, based on this analysis, I specify the problem as pollination, which means problem statement.

G

So the first are key item is a neighbor discovery such as link model megawatts to domain handling and the prefix dissemination and exchange, and also for Watty the secondly, mobility management also will consider, and so the one is the security and the privacy so other relevant work item to Appendix A such as a vehicle Identity Management, to having multiple interfaces.

G

Second, one is a multi happy to Eric's and a multicast and DNS naming and the solar discovery, and also in the on the meeting. Some the folks mentioned. A cubic foot about the six over some networks are also important, because now there is many automotive and O's 10 having interest in somewhere at least 32 X. That's why we summarized and analyzed so. This is a music, a sheet of free TV and we I'm and the free to X so for this document frequently are so beta.

G

In the previous version to case we have some intensive or subway and now I certain the text and current protocol, especially related to or IP based to a virtual networking, I immolate keeper and also specify the general problems. So at this moment, I just early mind a little architecture for our playground.

G

So you can see we have the beakers where so picker can talk to each other, usually about V to V and also beaker can talk to RFC up2i in order to access cloud or server or some corresponding mobile in the internet, and also we have a traffic control center. This is a mobility management, such as a picker environment case. Usually we can assume the Navigator can help its location, speed, the red Sun and it's related to traffic control center for efficient mobility management and also, we think the vehicle itself you can see.

G

This is what the left hand, side right, hand, side, the internal network, so vehicle or Odyssey. You can have its own well subnet, okay, because that is a issue you in vehicle can connect it using the Internet okay. So in that case the host some host can talk to some server in RSU. So in that case the question is a hard to talk to each other, so, secondly, a bigger case also moving fast. So especially, are the cruise control.

G

Adaptive cruise control case also hosted two first for, and we can say, they're providing the kinds of safety applications that case a hard to talk to each other. So the problem is pollination, so we focus on 3G what items? Maybe we can have a.

G

Yesterday I talked to correlation less and we can say at the moment the three items are important. Maybe speak up. Some other important, don't write them, but right now we focus on trees and other relevant for what I can also I summarized in Appendix A. So you can leave it also. The slide in Appendix, A, section isomerized, so mobile discovery needs to be a tailored for peculiar came. Fruit will be two are equal to X, so so was mentioned.

G

We have a three scenarios, but in high ratio case dynamically changing topology, multi-hop for being and high speed, because that makes our story very unless she not simpler, also NB parameter is also matter also required, because the pink from working past, in the case other see you maybe when a second it is out of con casual age. So a lot to write time, also mobile advertisement to introduce you to the others, TV. It's people based on spirit of intensity, so link. My mother is very important.

G

You can see the occupation section liners a linker a model case as long as were most have the same prefix. Always they can talk to each other, but wait while it's actually individual environment achilles. This assumption is not correct, especially those mature e-link connectivity case. It doesn't matter what's because of our limited channel link because of interference and.

I

So I think you're not comparing to the ipv6 link model, I, think you're, comparing to ipv6 over Ethernet and.

G

I

Career services handles all of this stuff. It doesn't make any assumptions about any prefixes whatsoever, but from the link local prefix you're not required to have an online prefix other than the link book, so this you're, comparing to an Ethernet and what we did with 6lowpan, as well as detecting the ORAC attachment a long time ago. Are you figuring out these things? They might not be written up that well in in RFC 48 62, but that they moved way past this thing. So I, don't think you need anything special to hear her way.

G

Clarified, ok, Istanbul is not running.

I

For most characteristics, this sort of one second thing or whatever yeah that's something interesting to go after, but now I, don't think it's the model.

G

Okay and the third one is a unlit ability between two most ruthless entropy s, because of other because moving past okay, they making connected a vehicle or other network Donna Louis elements. So in nineteen two segments are circulated. Our commercial lanes right, even though two groups are having the same prefix.

G

No cannot be the planet lowest amount, the vehicle connected to each other. So maybe it is not the photo I work for IP version. 6 original adding mentioned that it's not paste a link model doesn't work and also academics are no. The discovery should be extended s fourth row, the link in Thunderbird or not cast invalid.

G

Also, the MAC addresses pseudonym for privacy. Periodically MAC addresses changed, he means IP address usually are based on the MAC address interfaces right. So, in the case, the end-to-end, the transport layer session may be affected, so we needed to support the continuty for end-to-end the transport layer session we never considered last one is the prefix dissemination and the exchange, so the communication of two months are within different to internal or previously I'll show or RS you having internal matter right. So in the case, how to exchange the PX right, Kakui.

G

Second, trophy is a mobility management, so efficient mobility management, super important for seamless connectivity and timely data are exchanged between two endpoints remember. The traumatically code can have a GPS navigator, such as a dedicated navigator or smartphone app, where I can be used for the proactive or mobility or management. So the big hole, our mobile information. We can assume periodically reported it to traffic control center. Maybe we can say this: is the mobility anchor so last London meeting the three Priyanka masterly.

G

He showed the architecture having mobility anchor point, so we can earn so that we are free, diction over well feature mobility, traffic control, center or a mobility anchor point. The support I received upon tae pakka for being and the handover in for active manner.

G

And privacy, first of all, we needed to otherwise were worm, knows for secure or communication, and then we noted to that we needed to authenticate a vehicle and user right, so we can using a ravine ID.

G

Defecate within vehicle devices, ID generation, so we can authenticate. So we are this awesome vacation and the efficiently. My confirmed by other, see you assuming it has liquor our usual certificate information connected to awesome occasion, server and also we need to support to secure free to be free to excommunication, so secure, p2i or trophy TV. So one simple solution is that we can support using virtual certificates.

G

Well last early progress, Achilles the Microverse, the pseudonym no be discussed, but Mac study is so I want. I have a list to a3, so this document, and then we collect Peter back and also our working with attendees in this room, please Celeste a year and give it back to the others. And then we will reflect your commands on the revisions. To find a way is that we want to sum it is Z 1, :, meeting November, and then we start our tour for next step. Thank you.

G

So next, that's why you can see the appendix okay, so this is for more information, yeah.

A

Ok, very much fun so as we discussed in the interrupt le it's light, so we never you just mentioned many revisions. I mean reviews for the document, so we are looking for to three reviewers in what reviewer of this.

A

So is it's: we are you an author of this one or not, because if you are not, III would like to ask you if you could review this document.

A

A

Thank you very much. Thank you.

A

I was also discussing with very the woman, had to be 600 CVS, or he also can agree to to review that document version 25.

A

So with that, we are basically done for today as we certainly, this was a little bit short. So thank you.

D

E

As we said at the front, we want the problem statement to guide the recharter, so the problem statement, that's why we want the reviews so that that guides the discussion. The explained problems then guide which topics the working group should work on next.

D

E

Make sense Thanks.

A

So pretty much we.
