List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 16 Jul 2015 12:20:43 -0000 Hello, We will discuss this charter proposal in Prague. Alex --------------------------------------------------------------------- Goal ---- Establishing direct and secure IP connectivity between a few vehicles in close range is the goal of this group. Intro ----- Automobiles and vehicles of all types are increasingly connected to the Internet. Entertainment apps enhancing comfort on-board, reliable data exchanges for road safety, and automated driving, are highly appreciated marketing arguments for automobiles to hit the roads from now to year 2020. Emergency apps for new instrumented ambulances carry many benefits both to the users and to society in general. Why IP? ------- Whereas the Vehicle-to-Infrastructure technologies are considered completed and deployed in currently sold automobiles (e.g. car tethering through driver's cellular smartphone, or SIM in On-Board Unit, or cellular USB dongle, with NAT/DHCP and potentially Mobile IP), the Vehicle-to-Vehicle communications are still in an infancy stage: primitive link-specific data exchanges are limited to a non-harmonized and limited set of applications, such as ETSI's CAM/DENM presence signalling. On another hand, the industry needs to employ IP data exchanges between vehicles rather than link-specific exchanges, in order to benefit from the reuse of a huge number of a desktop Internet applications in a vehicular environment (extend the Internet to mobile platforms). Scenarios? ---------- Some of the scenarios needing IP V2V communications are: Cooperative Adaptive Cruise Control and Platooning of vehicles. In the emergency landscape other applications exhibiting a need for V2V comms are also important: virtual siren - emergency vehicle multicasting a radio warning to nearby vehicles to make place. How is V2V vs V2I? ------------------ Establishing direct and secure IP connectivity between a few vehicles in close range is the goal of this group. V2V is more than simply connecting a vehicle to the Internet (V2I). Because it needs a peer-to-peer manner of IP route establishment between equally-potent Routers in vehicles, in such a way to not disturb the V2I communications already in place. This manner is a step forward from known V2I Host-to-Router or Client-to-Server paradigms (protocols Neighbor Discovery, DHCP, ppp, Mobile IP, and similar). What kind of solutions? ----------------------- The current technical solutions considered to achieve IP V2V communications are of two kinds: IP routing protocols for n-hop path establishment between vehicles (e.g. Babel, OSPF, others) and 1-hop link-scoped IP protocol enhancements (such as route establishment with ICMP Router Advertisements). There is a concern in sending IPv6 packets over the current ETSI geonetworking protocols, with risks of the channel being swamped due to inefficiencies of the protocol, or simply due to communication abuse. What kind of requirements? -------------------------- The keyhole applications C-ACC, Platooning and virtual siren involve IP multicast mechanisms. The 1-hop IP V2V paths will gracefully support IP multicast. Due to the inherent characteristics of safety-related communications, all new V2V mechanisms must afford authenticity and confidentiality where necessary. Dynamically establishing ephemeral communication paths between automobiles in public areas must offer privacy safeguards for the end users (passengers). Establishing 1-hop IP V2V paths must not break the existing on-board protocols and applications which communicate with the infrastructure, possibly via multiple radios. Current version of Internet protocols ------------------------------------- The version of the IP protocol is IPv6, to acommodate the current generation of Internet protocols. For backwards compatibility, IPv4 may be considered as well, but not exclusively. Link-local addresses will be used. What SDOs may need this work? ----------------------------- The requirements and standards for an Internet of Vehicles are developed mainly at 3GPP, ETSI, NHTSA and IEEE. For Vehicle-to-Internet communications, 3GPP LTE and other cellular technologies represent the long-range connectivity method; for Vehicle-to-Vehicle communications, LTE Direct is currently specified. Several use-cases exhibit a need for IPv6 data exchanges between vehicles: ETSI's Cooperative Adaptive Cruise Control and Platooning. The IEEE developed a popular link for short-range communications - IEEE 802.11p "WAVE". The NHTSA wrote a set of requirements for V2V communications. Work Items ---------- - use-case and scenarios of C-ACC and Platooning at SDOs - Problem Statement for IP V2V application communications - Security and Privacy Requirements for IP V2V communications - Potentially new protocol, or protocol extensions for establishing IP paths for 1-hop V2V communications. With MIB and security. Timeline -------- - BoF in Yokohama - Couple of work items submitted to IESG in November 2016. - recharter to work on solution for IP V2V.

This draft is a work item of the Emergency Context Resolution with Internet Technologies Working Group of the IETF. Title : Next-Generation Vehicle-Initiated Emergency Calls Authors : Randall Gellens Brian Rosen Hannes Tschofenig Filename : draft-ietf-ecrit-car-crash-03.txt Pages : 22 Date : 2015-07-06 Abstract: This document describes how to use IP-based emergency services mechanisms to support the next generation of emergency calls placed by vehicles (automatically in the event of a crash or serious incident, or manually invoked by a vehicle occupant) and conveying vehicle, sensor, and location data related to the crash or incident. Such calls are often referred to as "Automatic Crash Notification" (ACN), or "Advanced Automatic Crash Notification" (AACN), even in the case of manual trigger. The "Advanced" qualifier refers to the ability to carry a richer set of data. This document also registers a MIME Content Type and an Emergency Call Additional Data Block for the vehicle, sensor, and location data (often referred to as "crash data" even though there is not necessarily a crash). An external specification for the data format, contents, and structure are referenced in this document. Profiling and simplifications of the general emergency call mechanism, as described in [RFC6443] and [RFC6881], are possible due to the nature of the functionality that is provided in vehicles such as the usage of Global Satellite Navigation System (GNSS). This document reuses the technical aspects of next-generation pan- European eCall (a mandated and standardized system for emergency calls by in-vehicle systems within Europe and other regions), as described in [I-D.ietf-ecrit-ecall]. However, this document specifies a different set of vehicle (crash) data, specifically, the Vehicle Emergency Data Set (VEDS) rather than the eCall Minimum Set of Data (MSD). The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-ietf-ecrit-car-crash/ There's also a htmlized version available at: https://tools.ietf.org/html/draft-ietf-ecrit-car-crash-03 A diff from the previous version is available at: https://www.ietf.org/rfcdiff?url2=draft-ietf-ecrit-car-crash-03 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.

Hello all,

During the noon discussion, = we were discussing whether we can use IPv6 link local address for one hop V= -V IP communication.

One reason is that the vehicl= e that discover a neighbor with link local IPv6 address can not distinguish= whether that is another vehicle or it is a smart phone in the car or it is= a smart phone from road side passengers. =C2=A0

If we want to use IPv6 link local address, a dedicate prefix for= V2V may needed.

Any thoughts?

List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 22 Jul 2015 12:37:19 -0000 Hi Dapeng, YEs, during the bar bof discussion a couple of people agreed LL addresses may be sufficient. A question was raised on whether or not the use of link-local addresses is enough to make vehicles in close range talk to each other in a 1-hop manner. To clarify, the topology would be the following: ---- ---- LL LL ---- ---- | H1 |-----| R1 |--o o--| R2 |-----| H2 | ---- ---- ---- ---- R1 and R2 may be able to communicate to each other by using their LL addresses, but could H1 talk to H2? H1, R1 are in car1, and H2, R2 are in car2. H1 is the GPS data source and H2 is the GPS data receiver. H1 needs to send the location data to H2, in order to inform the nearby vehicle about whether they can try to platoon themselves. The GPS data could be any other app-level data, for example the output of the odometer (speed measurement), or a camera streaming an IP video. To me, yes, LL addresses between R1 and R2 are sufficient, but they are not sufficient for communication between H1 and H2. Dedicate prefix for V2V management? Yes, why not, could be a good help in making addresses. What do the other think? Duplicate Address Detection taking too much time between R1 and R2? Maybe yes. Maybe avoid it? LL addresses using random MAC addresses? Good idea for privacy, but maybe depends on the privacy concerns? MAC address randomization impact on fast auto-configuration? Are MAC addresses required by the law to be visible just like the license plates are? Or are the MAC addresses more like the photo of the driver - private data accepted so by the government.

If this is the case, then I think this is multi-hop communication, rather 1= -hop. Random address generation may not be a good idea due to possible duplicated= address.

Sure. My point is we can not just use IPv6 link local addr= ess to fulfill the requirement. =C2=A0agree?

Hi, Dapeng= ,

=C2= =A0

Maybe we c= an distinguish a vehicle from a mobile by other means, rather than IP prefi= x / address.

For messag= e broadcast (e.g. safety related message), we may require a dedicated multi= cast address; for Unicast communication, I think we should make use of higher level information, such as TCP/UDP(or similar one) port= or application level information

=C2= =A0

Any though= ts?

Just that I dont think we need another kind of addresses. In other words: yes, just using LL addresses to realize V2V communication is not enough. no, in that messages between routers can be sourced just by their link-local addresses. Or maybe a prefix between vehicles would be needed. The creation of IP addresses _inside_ vehicles is currently a problem as well. Alex Le 22/07/2015 16:14, Dapeng Liu a écrit : > Sure.

But the Hosts inside each vehicle (H1 and H2) can not see each other, simple because they have Ethernet cable interfaces (not 802.11p). ---- ---- LL LL ---- ---- | H1 |-----| R1 |--o o--| R2 |-----| H2 | ---- ---- ---- ---- Ethernet 11p Ethernet Between H1 and H2 there are indeed 2 IP hops (R1 and R2). But the range of action of protocols we would like to concentrate on is the hop between vehicles. And use existing protocols on the hop _inside_ the vehicle. R1 and R2 should do something simple between them, on that single 1-hop, such that H1 and H2 can talk to each other, even though H1 and H2 may be separated by 2 or more IP hops. The structure inside each vehicle is relatively stable, there is no mobility. The structure between vehicles is highly dynamic, but they are all neighbors in IP terms.

Thanks,

2015-07-23 0:33 GMT+02= :00 Richard Roy <dickroy@alum.mit.edu>:
The real question is not "can we use IPv6 for single-= hop communications?",
the real question is "should we use a network protocol for single-hop<= br> communications when it is really a link-layer issue?"=C2=A0 I think mo= st people
would say "IPv6 is not necessary; MAC bridging at the data link layer = is
more than enough for this situation".

IPv6 carries an overhead (>39 bytes) that V2V comms, especially on the crowded safety channel, do not need.

Hi Dapeng,

 

To the risk of mentioning it again (Dick and I had a same discussion = in this ITS group around the same time last=C2=A0 year, please see the = logs) and again still agree with his statement below, the true question = is indeed not if we should use IP for one-hop V2V, but also which = application would need to have a 1-hop V2V in IPv6. =

 

Both ETSI and IEEE do not rely on IP for 1-hop V2V for safety-related = communications, as simply stated: it is not required, period. =

 

IP is necessary for interoperability and global connectivity. So, = this group should describe which applications would require either = interoperability between different technologies and/or global = connectivity (to the cloud, between vehicles over the cloud), and which = would require direct V2V communication (which would not be done better = via the cloud/backend).

 

Once we have such description, then we can discuss if we need IPv6 = for V2V and how to make it happen.

 

There could be some of these applications, e.g. proximity/social = networking (unsupervised LTE D2D, maybe WiFi direct, etc..), cellular = traffic offloading, to name a few=E2=80=A6but we should really take the = debate from the right end.

 

My two cents=E2=80=A6

 

Cheers,

The real question is not "can we use IPv6 for = single-hop communications?",
the real question is "should = we use a network protocol for single-hop
communications when it is = really a link-layer issue?"  I think most people

Hi Dapeng,

=C2=A0

To the risk of mentioning it again (Dick and I had a same discussion in this ITS group = around the same time last=C2=A0 year, please see the logs) and again still agree = with his statement below, the true question is indeed not if we should use IP = for one-hop V2V, but also which application would need to have a 1-hop V2V in = IPv6.

=C2=A0

Both ETSI and IEEE do not rely on IP for 1-hop V2V for safety-related communications, as = simply stated: it is not required, period.

=C2=A0

IP is necessary for interoperability and global connectivity. So, this group should describe = which applications would require either interoperability between different technologies and/or global connectivity (to the cloud, between vehicles = over the cloud), and which would require direct V2V communication (which would = not be done better via the cloud/backend).

=C2=A0

Once we have such description, then we can discuss if we need IPv6 for V2V and how to make = it happen.

=C2=A0

There could be some of these applications, e.g. proximity/social networking (unsupervised LTE = D2D, maybe WiFi direct, etc..), cellular traffic offloading, to name a = few=E2=80=A6but we should really take the debate from the right end.

=C2=A0

My two cents=E2=80=A6

OK. That comes to the question: should we use IP for one hop V2V.= I guess Alex have posted a picture to explain the scenario why IP is needed..=

2015-07-23 0:33 GMT+02:00 Richard Roy <dickroy@alum.mit.= edu>:

The real question is not =22can we use IPv6 for single-hop communications=3F=22,
the real question is =22should we use a network protocol for = single-hop
communications when it is really a link-layer issue=3F=22=C2=A0 I think = most people
would say =22IPv6 is not necessary; MAC bridging at the data link layer = is

IPv6 carries an overhead (>39 bytes) that V2V comms, especially on = the
crowded safety channel, do not need.

The real question is not "can we use IPv6 for s= ingle-hop communications?",
the real question is "should we use a network protocol for single-hop<= br> communications when it is really a link-layer issue?"=C2=A0 I think mo= st people

IPv6 carries an overhead (>39 bytes) that V2V comms, especially on the crowded safety channel, do not need.

Hi Geonet/ITS buddy,
My name is Paul Jeong, a faculty member at Sungkyunkwan University in
South Korea.

I heard your activity for ITS and VANET research at IETF.
I have much interest in this group because my lab research is focused on vehicular MAC protocols, data forwarding, safety driving, and navigation.
If some of you related to this group are still staying in the IETF93 venue,=
I would like to meet you and discuss how to contribute to the activity
of this group.
Please let me know when and where I can meet you this Friday.

Thanks.

Paul

Hi Dick

If an application always need only one = hop and it is alway deployed in the same manner in the car, probably we = can use only link layer technologies to address and transport = application data. But the same application could some time use one-hop = and another time use multi-hop communications =85 of course we could = manage this in an intermediate layer such as the ETSI facilities but it = becomes more complex. It could be simpler for the applications to always = use IP. 

If= the concern is just about the overhead due to the IP header, is could = be reduce a lot using header compression technics.

Maybe the = terminology should change from 1-hop to 1-variable-hop and n stable hops = (the Ethernets in the cars).

Not sure what = name to give to this: n-stable-hops plus 1 variable hop.
That's the structure in V2V.

Agree, link local address is not sufficient for V2V = communication.
But, if we consider only 1-hop = communication, it is probably sufficient.

I tend to agree.  Just that I dont think we need another = kind of addresses.

In other words: yes, = just using LL addresses to realize V2V communication is
not = enough.  no, in that messages between routers can be sourced just = by
their link-local addresses.

Or maybe a prefix between vehicles would be needed.

The creation of IP addresses _inside_ vehicles = is currently a problem as well.

It could be simpler for the applications to always use IP. It is simpler, but there's a much more compelling reason: security. First, understand that the notion of single-hop is fiction. - the other automobile that you want to communicate with is one you can't see (cross-traffic, blocked by a building ... he's about to t-bone you). - we always have three hops in the simplest topology -- local comms within each automobile plus a radio hop. There's a bunch of denial going on ... the two sides of the argument can be stereotyped into the "IoT' faction and the 'gateway faction'. The gateway group tries to deny the multiple hop characteristic, but it doesn't work. The highjacked Jeep conversation shows the fallacy of the gateway problem: you need end-to-end authenticity and gateways can't deliver it. > > > If the concern is just about the overhead due to the IP header, is > could be reduce a lot using header compression technics.
