Dear Jana Iyengar, Ian Swett, Martin Thomson (cc: quic WG),

As the designated experts for the QUIC registries, can you review the 
registration proposals in draft-ietf-quic-multipath-18 for us? These were 
already previously allocated as provisional registrations in -15 and some in a 
prior version of this document (I've copied the thread below). Please see:

https://datatracker.ietf.org/doc/draft-ietf-quic-multipath/

The due date is December 24th. 

If this is OK, we'll update the assignment at:

https://www.iana.org/assignments/quic/

Unless you ask us to wait for the other reviewers, we’ll act on the first 
response we receive.

With thanks,

David Dong
IANA Services Sr. Specialist
