Abstract

   This document analyzes the joint deterministic scheduling
   requirements for industrial field/backhaul networks, mainly
   including the determinacy, time synchronization, compatibility,
   scalability and scheduling cost demands.

1. Introduction

   Using three industrial wireless networking standards:
   ISA100.11a[IEC62734], WirelessHART[IEC62591] and WIA-PA[IEC62601], a
   deterministic network can be constructed by industrial field network.
   However, these industrial field networks belong to small and medium-
   sized networks whose network coverage is constant, for example, a
   range of plant. Therefore, industrial backhaul network can be
   introduced to make the industrial field network access higher-level
   network, or transit to other industrial field network. Thus, a new
   network architecture, the deterministic industrial field network -
   backhaul network is proposed in this draft. Some questions of
   deterministic network have been described in the draft [draft-finn-
   detnet-problem-statement-04], and the architecture and application
   have been illustrated in [draft-finn-detnet-architecture-04] and
   [draft-bas-usecase-detnet-02] separately.

   This network architecture is mainly used in industrial production,
   and it has a very high demand on the network data packet loss ratio,
