                draft-wang-detnet-backhaul-requirements-02

Abstract

   This document analyzes the requirements of joint deterministic
   scheduling in industrial field/backhaul networks. The requirements
   include six aspects: determinacy, time synchronization,
   compatibility, scalability, scheduling cost and unified management.

1. Introduction

   Industrial network includes many types of industrial field networks,
   such as the three industrial wireless network standards:
   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, for example, a field network
   usually covers a production area of a plant. Therefore, there is a
   need for industrial backhaul network that makes data flow from an
   industrial field network to other field networks, or transmits data
   access to Manufacturing Execution System (MES) or Enterprise
   Resource Planning (ERP). Thus, a new network architecture, the
   deterministic industrial field/backhaul network, is proposed in this
   draft. Some questions of deterministic have been described in the
   draft [I-D.finn-detnet-problem-statement], and the architecture and
   application have been illustrated in [I-D.finn-detnet-architecture]
   and [I-D.bas-usecase-detnet] separately.

   The proposed network architecture is mainly applied to industrial
   production environment, which has strong demands on packet loss
   ratio of network data, low jitter and determinacy and so on. The
