             Industrial Use Cases for In-Network Computing

Abstract

   Cyber-physical systems and the Industrial Internet of Things are
   characterized by diverse sets of requirements which can hardly be
   satisfied using standard networking technology.  One example are
   latency-critical computations which become increasingly complex and
   are consequently outsourced to more powerful cloud platforms for
   feasibility reasons.  The intrinsic physical propagation delay to
   these remote sites can already be too high for given requirements.
   The challenge is to develop techniques that bring together these
   requirements.  Utilizing available computational capabilities within
   the network for in-network computing concepts can be a solution to
   this challenge.  This document discusses selected industrial use
   cases to demonstrate how in-network computing concepts can be applied
   to the industrial domain and to point out essential requirements of
   industrial applications.

1.  Introduction

   The Internet is based on a best-effort network that provides limited
   guarantees regarding the timely and successful transmission of
   packets.  This design-choice is suitable for general Internet-based
   applications, but specialized industrial applications demand a number
   of strict performance guarantees, e.g., regarding real-time
   capabilities, which cannot be provided over regular best-effort
   networks.

   Enhancements to the standard Ethernet such as Time-Sensitive-
   Networking [TSN] try to achieve the requirements on the link layer by
   statically reserving shares of the bandwidth.  These concepts are
   well-suited for industrial settings with well understood
   communication patterns where the communication paths are encapsulated
   at the factory sites.  In the Industrial Internet of Things (IIoT),
