Abstract

   This document defines a generic data model for the 6TiSCH Operation
   Sublayer (6top), using the YANG data modeling language.  This data
   model can be used for future network management solutions defined by
   the 6TiSCH working group.  This document also defines a list commands
   internal to the 6top sublayer.

1.  Introduction

   This document defines a generic data model for the 6TiSCH Operation
   Sublayer (6top), using the YANG data modeling language.  This data
   model can be used for future network management solutions defined by
   the 6TiSCH working group.  This document also defines a list commands
   internal to the 6top sublayer.  This data model gives access to
   metrics (e.g. cell state), TSCH configuration and control procedures,
   and support for the different scheduling mechanisms described in
   [I-D.ietf-6tisch-architecture].  The 6top sublayer addresses the set
   of management information and functionalities described in
   [I-D.ietf-6tisch-tsch].

   For example, network formation in a TSCH network is handled by the
   use of Enhanced Beacons (EB).  EBs include information for joining
   nodes to be able to synchronize and set up an initial network
   topology.  However, [IEEE802154e] does not specify how the period of
   EBs is configured, nor the rules for a node to select a particular
   node to join. 6top offers a set of commands so control mechanisms can
   be introduced on top of TSCH to configure nodes to join a specific
   node and obtain a unique 16-bit identifier from the network.  Once a
   network is formed, 6top maintains the network's health, allowing for
