I also have several questions as listed below:
1. How to set the length (in time) of each cell. This should be related to the number of retransmissions, i.e., for a higher number of retransmissions, the cell length should accordingly be set longer? This may incur some efficiency issue?
2. What is default channelslot offset of EB, on which a new node unjoined node should listen?
3. If neither K1 nor K2 is pre-provisioned, a joining node uses the secExempt mechanism (IEEE Std 802.15.4, Section 9.2.4) to process all correctly-formatted EBs.
Here I found no secExempt mechanism in Section 9.2.4 in IEEE Std 802.15.4
4. “Many mechanisms exist for discrimination between networks, the details of which are out of scope.” According to current field setting, it is difficult to differentiate different networks. Does it mean EB contains other field that can be used for this purpose?

Hi Xavi,
Thanks for addressing the reviews. I have placed this version on the Feb 16 2017 telechat so Tero, Ralph and Brian will have a chance to chime in by then.
Regards
Suresh

Dear all,
we have submitted a new version of minimal addressing the last comments received during the call last Friday. Main changes affect the security section where Tero's comments have been taken into consideration.
thanks everybody who contributed and kind regards,
Xavi

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the IPv6 over the TSCH mode of IEEE 802.15.4e of the IETF.
Title : Minimal 6TiSCH Configuration
Authors : Xavier Vilajosana

Filename : draft-ietf-6tisch-minimal-19.txt
Pages : 26
Date : 2017-01-25
Abstract:
This document describes a minimal mode of operation for a 6TiSCH
Network. A minimal mode of operation is a baseline set of protocols,
recommended configurations and modes of operation sufficient to
enable a 6TiSCH functional network. 6TiSCH provides IPv6
connectivity over a Time Synchronized Channel Hopping (TSCH) mesh
composed of IEEE Std 802.15.4 TSCH links. This minimal mode uses a
collection of protocols with the respective configurations, including
the 6LoWPAN framework, enabling interoperable IPv6 connectivity over
IEEE Std 802.15.4 TSCH. This minimal configuration provides the
necessary bandwidth for network and security bootstrap, and defines
the proper link between the IETF protocols that interface to IEEE Std
802.15.4 TSCH. This minimal mode of operation should be implemented
by all 6TiSCH compliant devices.
