Ballot Text

Technical Summary

   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 method uses the UDP Options packetization layer.  It
   allows an application to discover the largest size of datagram that
   can be sent across a network path.  It also provides a way to allow
   the application to periodically verify the current maximum packet
   size supported by a path and to update this when required.

Working Group Summary

   Nothing worth report as there we no controversies in the WG. 

Document Quality

   An implementation in a fork of FreeBSD was reported at IETF 101, London with prototype support
using RES/REQ exchanges, which at the time were proposed within UDP options.
The wire format has not changed since. It was also implemented in a scapy,
which was used as a test suite during development
([https://github.com/adventureloop/network-tests/tree/master/udpoptions](https://github.com/adventureloop/network-tests/tree/master/udpoptions)).
