Hi,

the new draft on RTO restart address the following comments from the IESG (thanks for the feedback):

o  Clarified, in the abstract, that the modified restart causes a smaller retransmission delay in total.

o  Clarified, in the introduction, that the fast retransmit algorithm may cause retransmissions upon
    receiving duplicate acknowledgments, not that it unconditionally does so.

o  Changed wording from "to proposed standard" to "to the standards track".

o  Changed algorithm description so that a TCP sender MUST track the time elapsed since the
    transmission of the earliest outstanding segment. This was not explicitly stated in previous
    versions of the draft.


Cheers,
Per
