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], and there is little joint scheduling scheme that can
   be applied to industrial networks.

   Nowadays, in the use case document[draft-bas-usecase-detnet] and
   architecture document[draft-finn-detnet-architecture] submitted by
   the IETF DetNet working group, a deterministic network based on
   Ethernet has already been researched. The document proposes a
   network architecture based on SDN technology, which can accurately
   control the transmission of data streams. However, the document does
