         Joint Scheduling Architecture for Deterministic Industrial
                          Field/Backhaul Networks
                draft-wang-detnet-backhaul-architecture-02

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 network is one of essential elements of industrial
   network. With the help of deterministic network, industrial field
   network can greatly enhance the network performance in terms of
   reducing transmission delay. Thus, applying deterministic network
   into the whole industrial network has attracted a lot of attention
   recently. Deterministic network is mainly focused on the industrial
   field networks, such as ISA100.11a [IEC62734], WirelessHART
   [IEC62591] and WIA-PA [IEC62601]. In order to solve the problem of
   data transmission in different industrial field networks and the
   issue of data flows between industrial field networks and wide area
