So that possibly makes sense internally to the car, although possibly not. It doesn't make a lot of sense to me between cars, except perhaps in the most restricted applications. When you talk about capacity constrained RF channels, it sounds like you're talking about car-to-car traffic, or car-to-infrastructure traffic. But this constrained port mapping protocol sounds way too restrictive for either of those contexts. -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
