Abstract:
This document describes the environment, problem statement, and goals
of On-The-Fly (OTF) scheduling, a Layer-3 mechanism for 6TiSCH
networks. The purpose of OTF is to dynamically adapt the aggregate
bandwidth, i.e., the number of reserved soft cells between neighbor
nodes, based on the specific application constraints to be satisfied.
When using OTF, softcell and bundle reservation is distributed:
through the 6top interface, neighbor nodes negotiate the cell(s) to
be (re)allocated/deleted, with no intervention needed of a
centralized entity. This document aims at defining a module which
uses the functionalities provided by the 6top sublayer to (i) extract
statistics and (ii) determine when to reserve/delete soft cells in
the schedule. The exact reservation and deletion algorithm, and the
number and type of statistics to be used in the algorithm are out of
scope. OTF deals only with the number of softcells to be reserved/
deleted; it is up to 6top to select the specific soft cells within
the TSCH schedule.
