Abstract:
   This document describes a robust method for Path MTU Discovery
   (PMTUD) for datagram Packetization Layers (PLs).  It describes an
   extension to RFC 1191 and RFC 8201, which specifies ICMP-based Path
   MTU Discovery for IPv4 and IPv6.  The method allows a PL, or a
   datagram application that uses a PL, to discover whether a network
   path can support the current size of datagram.  This can be used to
   detect and reduce the message size when a sender encounters a network
   black hole (where packets are discarded).  The method can probe a
   network path with progressively larger packets to discover whether
   the maximum packet size can be increased.  This allows a sender to
   determine an appropriate packet size, providing functionally for
   datagram transports that is equivalent to the Packetization Layer
   PMTUD specification for TCP, specified in RFC 4821.

   The document also provides implementation notes for incorporating
   Datagram PMTUD into IETF datagram transports or applications that use
   datagram transports.

   When published, this specification updates RFC 4821.
