[Maria Rita PALATTELLA <[e-mail]>]

Dear Pascal,

Best wishes to  you and all  6TiSCH folk for 2016!

I support the new version of the abstract and Intro  of the minimal draft.

Subject: Re: [6tisch] Consensus call on Summary of proposed resolution for issue 40 V3

Dear all:

With my best wishes for a great year 2016, please find a reminder that we have a consensus (last) call running on the abstract and introduction of the minimal draft. 
In order to cope with the Year-End break, the call continues till next Friday. So far, all I've been seeing is consensus with the latest change that Ralph proposed. 
Where we are at now is as below:

--------------
Abstract

BEFORE

This document describes the minimal set of rules to operate an IEEE
802.15.4 Timeslotted Channel Hopping (TSCH) network.  This minimal mode of operation can be used during network bootstrap, as a fall- back mode of operation when no dynamic scheduling solution is available or functioning, or during early interoperability testing and development.

 ---------------
AFTER

This document describes a minimal mode of operation for a 6TiSCH Network, to provide IPv6 connectivity over a Non-Broadcast Multi-Access (NBMA) mesh that is formed of IEEE 802.15.4 Timeslotted Channel Hopping (TSCH) links.
 
This minimal mode uses a collection of protocols including the 6LoWPAN framework and RPL to enable interoperable IPv6 connectivity over IEEE 802.15.4 TSCH with minimal network configuration and infrastructure.

1.  Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].

2.  Introduction

   The nodes in a IEEE 802.15.4 TSCH network follow a communication
   schedule.  The entity (centralized or decentralized) responsible for
   building and maintaining that schedule has precise control over the
   trade-off between the network's latency, bandwidth, reliability and
   power consumption.  During early interoperability testing and
   development, however, simplicity is more important than efficiency.
   One goal of this document is to define the simplest set of rules for
   building a TSCH-compliant network, at the necessary price of lesser
   efficiency.  Yet, this minimal mode of operation MAY also be used
   during network bootstrap before any schedule is installed into the
   network so nodes can self-organize and the management and
   configuration information be distributed.  In addition, the minimal
   configuration MAY be used as a fall-back mode of operation, ensuring
   connectivity of nodes in case that dynamic scheduling mechanisms fail
   or are not available.  The IEEE 802.15.4 specification provides a
   mechanism whereby the details of slotframe length, timeslot timing,
   and channel hopping pattern are communicated when a node time
   synchronizes to the network [IEEE802154].  This document describes
   specific settings for these parameters.

1.  Introduction

   A 6TiSCH Network provides IPv6 connectivity over a Non-Broadcast
   Multi-Access (NBMA) mesh that is formed of IEEE 802.15.4
   Timeslotted Channel Hopping (TSCH) links.  

   The 6TiSCH [I-D.ietf-6tisch-architecture] architecture requires the
   use of both RPL and the 6LoWPAN adaptation layer framework 
   ([RFC4944], [RFC6282]) as defined over IEEE 802.14.5.
   6LoWPAN Neighbor Discovery [RFC6775] (ND)  is also required to
   exchange Compression Contexts,  form IPv6 addresses and register
   them for the purpose of Duplicate Address Detection, Address
   Resolution and Neighbor Unreachability detection over one
   TSCH link.
    
   Nodes in a IEEE 802.15.4 TSCH network follow a communication
   schedule.  A network using the simple mode of operation uses a
   static schedule.

   This specification defines operational parameters and procedures 
   for a minimal mode of operation to build a 6TiSCH  Network.
  The 802.15.4 TSCH mode, the 6LoWPAN framework, RPL [RFC6550],
   and its Objective Function 0 (OF0) [RFC6552], are used unmodified,
   but  parameters and particular operations of TSCH and RPL are 
   specified  to guarantee interoperability between nodes in a 6TiSCH
   Network. 
   
   More advanced work is expected in the future to complement the
   Minimal Configuration with dynamic operations that can adapt the
   Schedule to the needs of the traffic in run time.


2.  Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].


Cheers,

Pascal
