Abstract:

   QUIC endpoints commonly use 1200-byte datagrams during the handshake
   and only start Path MTU Discovery afterward.  This means that just-
   established QUIC connections cannot immediately use larger datagrams,
   which is especially limiting for MASQUE protocols and for
   WebTransport.  This document defines Parallel Probing DPLPMTUD
   (PPDPLPMTUD), which probes several packet sizes early during the QUIC
   handshake, so a larger discovered size is usable during later
   handshake phases and especially after handshake completion.  The same
   discovery process is also used for path migration.
