Minimal IPv6 over the TSCH Mode of IEEE 802.15.4e (6TiSCH) Configuration

Abstract

   This document describes a minimal mode of operation for an IPv6 over
   the TSCH mode of IEEE 802.15.4e (6TiSCH) network.  This minimal mode
   of operation specifies the baseline set of protocols that need to be
   supported and the recommended configurations and modes of operation
   sufficient to enable a 6TiSCH functional network.  6TiSCH provides
   IPv6 connectivity over a Time-Slotted 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 IPv6 Low-Power Wireless Personal Area Network (6LoWPAN)
   framework, enabling interoperable IPv6 connectivity over IEEE Std
   802.15.4 TSCH.  This minimal configuration provides the necessary
   bandwidth for network and security bootstrapping 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.
