Re: Last Call: <draft-ietf-6man-rfc1981bis-04.txt> (Path MTU Discovery f

Lars,

the last paragraph of the introduction reads:

  An extension to Path MTU Discovery defined in this document can be
  found in [RFC4821].  It defines a method for Packetization Layer Path
  MTU Discovery (PLPMTUD) designed for use over paths where delivery of
  ICMP messages to a host is not assured.

Given that ICMP delivery cannot be assured over the vast majority of paths in 
the current Internet, should this document make a recommendation to implement 
RFC4821?


Could you please substantiate that assertion?

Best regards,
Ole
