Yes, and it would be good if PMTUD worked, and ECN, oh and large UDP-packets for DNS, and BCP38, and... and... and. The internet is a very diverse and complicated beast and if end systems can properly detect PMTU by doing discovery of this, it might work. Requiring the core and distribution to change isn't going to happen overnight, so end systems first. Make sure they can properly detect PMTU by use of nothing more than "is this packet size getting thru" (ie no ICMP-NEED-TO-FRAG) or alike, then we might see partial adoption of larger MTU in some parts and if this becomes a major customer requirement then it might spread. -- Mikael Abrahamsson email: [email protected]
