Greetings authors, I have read through your draft and look forward to your presentation at the upcoming TSVWG session.
Here are some questions / comments: *Terminology*: is it correct to assume that wherever I see the acronym *LTP*, which is not defined in the draft, it should actually be *TLP*? *DPLPMTUD*: I see that there is a reference to PLPMTUD (RFC 4821) but none to its datagram counterpart DPLPMTUD (RFC 8899). The latter is an essential underpinning tp draft-spiriyath-ipsecme-dynamic-ipsec-pmtu (which is also referenced). You may want to consider pointing to RFC 8899 also. *LMAP value determination*: In the draft I see: if IPVersion is 4: LMAP = FragLen elif IPVersion is 6: LMAP = FragLen + 40 As far as I am aware, there is no rule that requires that initial fragments be as large as possible; rather, the fragmenting node has discretion to "even out" the fragment sizes if the size of the packet to be fragmented would result in one (or a series of) maximum-sized fragment and one that is quite small. Indeed, I vaguely recall that this is encouraged to avoid further downstream fragmentation. If I am correct in this belief, then the formula above is fundamentally flawed. If you have a reference that supports the notion that an initial fragment is required to be as large as the outgoing MTU allows, please include a citation. See you at the presentation. Thanks and regards, Mike Heard
