Abstract:
The recently published [IEEE802154e] standard formalizes the concept
of link-layer resources in LLNs. Nodes are synchronized and follow a
schedule. A cell in that schedule corresponds to an atomic link-
layer resource, and can be allocated to any pair of neighbors in the
network. This allows the schedule to be built to tightly match each
node's bandwidth, latency and energy constraints. The [IEEE802154e]
standard does not, however, present a mechanism to do so, as building
and managing the schedule is out of scope of the standard. This
document describes the 6TiSCH Operation Sublayer (6top) and the
commands it provides to upper network layers such as RPL or GMPLS.
The set of functionalities includes feedback metrics from cell states
so network layers can take routing decisions, TSCH configuration and
control procedures, and the support for decentralized, centralized or
hybrid scheduling. In addition, 6top can be configured to enable
packet switching at layer 2.5, analogous to GMPLS.
