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

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.

I'll reiterate my suggestion to use a higher level description here in the
abstract:

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 an operational parameters and procedures
s/an//
for a minimal mode of operation to build a 6TiSCH Network, using
the Routing Protocol for LLNs (RPL) and a static TSCH Schedule.
Either delete ", using the Routing Protocol for LLNs (RPL) and a static TSCH
Schedule" or mention all the other protocols in use here, as well.
Do you want to mention the join process? Security?
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.
