IEEE 802.15.4 Information Element encapsulation of 6TiSCH Join and
Enrollment Information
draft-ietf-6tisch-enrollment-enhanced-beacon-13
Abstract
In TSCH mode of IEEE STD 802.15.4, opportunities for broadcasts are
limited to specific times and specific channels. Routers in a Time-
Slotted Channel Hopping (TSCH) network transmit Enhanced Beacon (EB)
frames to announce the presence of the network. This document
provides a mechanism by which additional information critical for new
nodes (pledges) and long sleeping nodes may be carried within the
Enhanced Beacon in order to conserve use of broadcast opportunities.

1. Introduction
[RFC7554] describes the use of the Time-Slotted Channel Hopping
(TSCH) mode of [ieee802154]. As further detailed in [RFC8180], an
Enhanced Beacon (EB) is transmitted during a slot designated as a
broadcast slot.
1.1. Use of BCP 14 Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
"OPTIONAL" in this document are to be interpreted as described in
BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all
capitals, as shown here.
Other terminology can be found in [I-D.ietf-6tisch-architecture] in
section 2.1.
1.2. Layer-2 Synchronization
As explained in section 6 of [RFC8180], the Enhanced Beacon (EB) has
a number of purposes: synchronization of Absolute Slot Number (ASN)
and Join Metric, carrying timeslot template identifier, carrying the
channel hopping sequence identifier, and indicating the TSCH
SlotFrame.

An EB announces the existence of a TSCH network, and of the nodes
already joined to that network. Receiving an EB allows a Joining
Node (pledge) to learn about the network and synchronize to it.
