This document specifies how a UDP Options sender implements Datagram Packetization Layer Path Maximum Transmission Unit Discovery (DPLPMTUD) as a robust method for Path Maximum Transmission Unit Discovery. This is a robust method for Path MTU Discovery (PMTUD) that uses the UDP Options Packetization Layer (PL). It allows a datagram application that uses this PL, to discover the largest size of datagram that can be sent across a network path.
