Final Charter for Working Group

The MTU Discovery Working Group is chartered to produce an RFC
defining an official standard for an IP MTU Discovery Option. ``MTU
Discovery'' is a process whereby an end-host discovers the smallest MTU
along a path over which it is sending datagrams, with the aim of
avoiding fragmentation.


Date Milestone Associated documents
Oct 1989 Encourage the participation of gateway implementors, since the MTU discovery process affects the design and performance of IP gateways.

Done milestones

Date Milestone Associated documents
Done Decide if the proposal in RFC 1063 is sufficient, or if there are flaws to be corrected, or possible improvements to be made. Or, decide that it is unwise to create an official standard.
Done Encourage sample implementations of end-host and gateway portions of MTU Discovery for popular software (BSD-derived kernels, primarily). Encourage rapid implementation by major gateway vendors, since this option is relatively useless without widespread support.
Done Unless the proposal in RFC 1063 is acceptable, write a new RFC describing a different approach.
