It's true that DSCPs may be remarked, but RFC 2474
already stated
Packets received with an unrecognized codepoint SHOULD be forwarded
as if they were marked for the Default behavior (see Sec. 4), and
their codepoints should not be changed.
The rtcweb WG also counts on e2e DSCPs.
After the LE PHB experience I would suggest to probably use
DSCP 5 which has got better chances to survive ToS bleaching (maybe
around 80%), if I understand
https://www.sciencedirect.com/science/article/pii/S0140366417312835
correctly. Diffserv behavior is usually configurable and can be changed
without replacing the network gear.
Regards
Roland
