Dear folks.
I'd like to discuss this draft "The PMTU Discovery for IPv6 Using
Hop-by-Hop Option Header", it's not submitted yet. Before I propose, I
want to listen some comments and opinion from IPv6 folks. I'll attach
this draft. Please look into and response.

Abstract
This document presents a new method for the PMTU discovery for IPv6.
To discover the PMTU of a path, a source node measures its actual PMTU
using the newly defined Hop-by-Hop Option header, whereas a source
node initially assumes that the PMTU of a path is the known MTU of
the first hop in the path in the previous one [1981]. In order to
measure the actual PMTU, the source node sends the IP packet with the
newly defined Hop-by-Hop Option header to the destination node with
the first data packet when node is beginning. This can eliminate the
chance of occurrence of several iterations of the somewhat complex
discovery cycle (sending a packet, receiving a Packet Too Big message,
reducing a packet size). Most of all, since existing PMTU has a weak
point for security and denial-of-service attacks, this document
suggests a security function when PMTU is going on.
All IPv6 nodes, including both hosts and routers, must implement newly
Options as defined in this specification.
