    abstract =  {This document describes a robust method for Path MTU Discovery (PMTUD) for datagram packetization layers. It allows these layers to probe an Internet path with progressively larger packets to determine a maximum packet size This method is described as an extension to RFC 1191 and RFC 8201, which specify ICMP-based Path MTU Discovery for IP versions 4 and 6. The document provides functionally for datagram transports that is equivalent to the packetization layer PMTUD specification for TCP, specified in RFC4821.},
