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.
