Dear all; In order to address Ralph's issues on the minimal draft, we proposed a rewording of the abstract and the introduction. This reopens a 2-weeks period of last call for these particular sections, with the text as below. If you disagree with the text, please let us know before January 1st. Cheers, Pascal -----Original Message----- From: Ralph Droms (rdroms) Sent: lundi 14 décembre 2015 19:35 To: Pascal Thubert (pthubert) <pthubert@cisco.com> Cc: 6tisch@ietf.org Subject: Re: Summary of proposed resolution for issue 40 V3 > On Dec 14, 2015, at 11:16 AM 12/14/15, Pascal Thubert (pthubert) <pthubert@cisco.com> wrote: > > Hello Ralph: > > If you’re OK with this round, we’ll open a one week call to the WG to check consensus. > The proposed replacement for slotted aloha is subject to change again > in that phase J > > Please let us know; Assessing WG consensus is OK with me. - Ralph > > Pascal > > ---------------------------------------------------------------------- > ----------- > > Abstract update: > > BEFORE > > > -------------- > Abstract > > This document describes the minimal set of rules to operate an IEEE > 802.15.4 Timeslotted Channel Hopping (TSCH) network.
