         Joint Scheduling Architecture for Deterministic Industrial

Abstract

   The joint scheduling between industrial field network and backhaul
   network is important to satisfy the requirements of deterministic
   delay for data flows in factories. This document describes a joint
   scheduling architecture for deterministic industrial field/backhaul
   networks. Taking WIA-PA, an international standard about industrial
   wireless field network, and IPv6-based backhaul network as an
   example, this document depicts how the joint scheduling architecture
   works in detail.

1. Introduction

   Deterministic transmission is one of essential elements of
   industrial network. Thus, applying deterministic network into the
   whole industrial network has attracted a lot of attention recently.
   Deterministic network is also focused on the industrial field
   networks, such as ISA100.11a [IEC62734], WirelessHART [IEC62591] and
   WIA-PA [IEC62601]. Most industrial field networks are in a middle or
   small size, and the network coverage is constant. Therefore, An
   industrial backhaul network is needed to connect different types of
   industrial field networks. Meanwhile, the deterministic transmission
   of the industrial backhaul network should also be guaranteed.

   However, there are little considerations about joint scheduling
   between industrial backhaul network and industrial field network.
