Dear WG

The HbH draft is soon to expire, and I do not see that we had a deep discussion and a consensus on which kind of signaling will work best for DetNet IPv6.

We have a proposal to encapsulate over UDP, which appears ready for adoption, and one to use IPv6 extension headers, which is ready to expire; arguments on the table include:

Size of the encapsulation
Complexity of silicon implementation
Reuse of MPLS design
IP version independence
DetNet and SRv6
Flow vs path (the pipe and the water)

I believe that each of those topics deserves a solid discussion before the group jumps on the UDP solution. The wrong decision now could mean a lot of wasted effort in the future.

Regards,

Pascal
