Abstract

Joint scheduling of industrial field network and backhaul network is
significant for end-to-end deterministic delay requirements of data
flows in factories. This document describes a joint scheduling
architecture for deterministic industrial field and backhaul
networks. Taking WIA-PA wireless field network and IPv6-based
backhaul network as an example, this document shows how the joint
scheduling architecture works.

1. Introduction

Deterministic network is an essential element of the industrial
network. Using deterministic network in the industrial field can
enhance the network performance and greatly reduce the network
packet loss. Thus, it is the future development direction of
industrial network technology to use deterministic networks in the
whole industrial network. Deterministic networks in industrial
networks are mainly concentrated on the industrial field networks,
such as ISA100.11a[IEC62734], WirelessHART[IEC62591] and WIA-
PA[IEC62601]. At the same time, in order to solve the transmission
problem among industrial field networks as well as the transmission
problem between industrial field networks and wide area networks, a
nondeterministic industrial backhaul network is often deployed in

can be applied to industrial networks.
