The meeting was called to order by co-chairs Yaakov Stein and Stewart
Bryant. Karen O'Donoghue took the minutes. The blue sheets were
distributed, and the agenda was presented with no additions.  

Report on Paris Interim Meeting, Yaakov Stein
=============================================
Slides: tictoc-3.pdf

Yaakov presented an overview of the Paris Interim meeting. The meeting
notes (###) and an initial requirements  and capabilities matrix (###)
are provided in the proceedings for this meeting. There was some
discussion on terminology and the consensus represented at the
meeting. Everyone is strongly encouraged to read the full meeting
report and raise issues on the list. The working group needs to
continue to work to collect and understand the requirements. On path
support was discussed at some length including the definition of
on-path support and security issues associated with it. Several felt
that more information was needed and participants were encouraged to
post to the list. 


Requirements, Silvana Rodrigues
===============================
Document:  draft-rodrigues-lindqvist-tictoc-req-00.txt
Slides:  tictoc-2.pdf

Silvana presented the updated requirements document. Stewart Bryant
pointed out that there was some reluctance on the part of participants
to commit to numbers, but that we really need to start putting these
down. Blank numbers people will ignore. Stefano Ruffini pointed out
that we need to define and amplify on the terms used to define the
requirements. Marshall Eubanks indicated that we really need to
understand the time duration over which these numbers apply. Further
discussion was directed to the list. 

Modularization Draft, Karen O’Donoghue
======================================
Document:  draft-stein-tictoc-modules-02.txt
Slides: ###

Karen O'Donoghue provided an overview of the updated modularization
draft. The primary discussion point is that the modularization draft
has evolved into a more generalized architecture document. It is
expected that each of the solution documents will reference where they
fit into the architecture document. There were questions on the
definition of frequency and time distribution as an application
layer. Was an OSI like model appropriate as a starting point? The
working group was directed to the ITU G.805 document for definitions
of time and frequency. There were jabber discussions on the priorities
of attacking problems.   

RAN Synchroization Requirements, Lan Wang
=========================================
Document:  draft-zhou-tictoc-ran-sync-req-01.txt
Slides:  tictoc-4.pdf

Lan Wang presented a discussion on the Synchronization Requirements
for RAN & Backhaul Update. Marshall Eubanks asked about the geographic
distribution or size involved in the 1.5 microsecond
requirements. These requirements need to be fed into the requirements
draft.  

Further Discussion on the Discussion on Requirements Table
==========================================================
The agenda item for upcoming steps was tabled for further discussion
on the requirements document as the requirements need to be completed
prior to the definition of some of the next steps. Again the
conversation focused on the definition of terms and how they mapped to
the different solutions. Marshall pointed out that there is implicit
time averaging and that the columns don't have the same averaging
windows. It was proposed to have a breakout session at 2:00 pm on
Wednesday to further develop the table.  

The meeting was adjourned.
