Dear all

We have submitted a draft that defines the protocol number option in UDP 
options. The protocol number option specifies the protocol immediately 
following the UDP header.

Currently, the only information about the packet encapsulated in UDP is 
the port number corresponding to the service. In addition, UDP-based 
protocols such as QUIC are increasingly used as transport for applications.
When using such protocols, it is not possible to provide the UDP layer 
with information about the transport layer protocol that follows the UDP 
header. The protocol number option provides this information.

We believe this option would be beneficial for extending the transport 
protocol with UDP.

If you are interested in it or have any comments, I really appreciate 
your feedback or comments.

Thank you.
