The next-generation Industrial and Tactile Internet of Things (IoT) will support smart Cyber-Physical Systems and Industry 4.0, including Smart Cities, and Industrial Automation. It will also support bandwidth-intensive applications, ie Data-Centers, Cloud Computing and the Metaverse. This paper explores ultra-high reliability and throughput in a “Software-Defined Deterministic Internet of Things”.  Multiple “Software-Defined Deterministic Wide Area Networks” (SDD-WANs) are introduced into layer 3, using simple “Deterministic Packet Switches” (D-switches).  All complex functions are removed from layer-3 hardware, and are migrated into the SDN control-plane. The resulting D-switches can be fabricated on a single \emph{Integrated Circuit}, ie FPGA. To maximize reliability, mission-critical data is routed over multiple paths. A simple Forward Error Correcting (FEC) code transmits coded data over additional paths, to tolerate edge failures.  This architecture offers many benefits: (a) “Ultra-High Reliability” is achieved, while reducing bandwidth costs; (b) “Ultra-High Throughput” is achieved, to support Data- Centers, Cloud Computing and the Metaverse; (c) The “bare-metal” D-switches use FPGAs to dramatically lower costs, with potential cost-savings reaching $1-2 Trillion (USD) over  2025…2030.  (d) The lower costs address the IEEE’s “Digital Divide”, and can potentially improve Internet access for much of the world. (e) The  Software-Defined-Networking (SDN) control-plane integrates Post-Quantum-Cryptography (PQC) and Artificial Intelligence (AI), and achieves ultra-secure Quantum-Safe communications, where each nation can achieve unprecedented protection of its critical infrastructure from external cyber-attackers.

The next-generation Internet of Things (IoT) will enable Industry 4.0 and Smart Cyber-Physical Systems, including Smart Cities and Smart Manufacturing. These Smart Systems require: (i) ultra-low latencies, and (ii) immunity from cyber-attacks. This paper explores a “Software-Defined Deterministic IoT”, with Artificial Intelligence (AI) for Cyber-Security. It introduces a new sub-layer (3a) of “Software Defined Wide Area Networks (SD-WANs)”, using simple and secure deterministic packet switches (ie low-cost FPGAs). A “Software Defined Networking” (SDN) control-plane uses collaborative AI systems to implement Zero Trust Architectures (ZTAs) and Guaranteed Intrusion Detection Systems (IDSs), to control access to all critical resources. The SD-WANs can support millions of Deterministic Virtual Private Networks (DVPNs).The approach has many benefits: (i) All interference, congestion, and Distributed Denial-of-Service (DDOS) attacks are eliminated; (ii) End-to-end delays are determined by the speed of light in fiber; (iii) The SD-WANs provide hardware support for the US NIST ZTA and Post Quantum Cryptography (PQC); (iv) All communications within a DVPN are encrypted with PQC, and are immune to attacks from Quantum Computers; (v) The expected number of a successful cyber-attacks per year against a nation’s critical infrastructure from external cyber-attackers is zero, when using Quantum-Safe ciphers; (vi) Total cost savings are estimated at $100s of Billions USD per year.
