can see the preliminaries of it if you try to browse a real traffic
lights controller but situated - for now - in-lab at 193.48.19.10).  The practical issues we have at this time is the support of IPv4 (RSU only supports IPv4 and that will not change in the next few years) and certificates (you will understand the certificate problem if you try to browse it).

Speaking of which, I am currently looking for someone to test the DIASER UDP protocol on IPv4 to query this traffic lights controller. In a secure manner, because the data is sensitive. I have the python scripts ready for DIASER on UDP on IPv4, to query the traffic lights status and their expected (well like in weather prediction) state duration.

If successful, then we can talk about writing an individual Internet Draft containing an IPv4 RIO in an IPv6 RA over OCB, to allow making a direct IP path from the car to talk directly to the traffic lights. A colleague programmer is already interested.

I also asked a few of the current project partners, but they are not interested for the moment - lack of time, at this time. They tell me it should be me on the RSU who does that DIASER and then convert it to SPAT and upload it to cloud. When I reply with the end-to-end principle (let the cloud query the controller, rather than in-middle convertor), they tell me that everybody does it that way (RSU reads controller data, and RSU uploads to cloud). So I am trying to show a different way is possible: make the cloud query the traffic lights controller, and the car query the traffic lights controller, and anybody who so wishes, yet in a secure manner (probably some form of certificates).

That is a current problem that I have.
