Rethinking Industrial Networks in the Age of IT
Industrial networks are undergoing a radical shift from closed, static OT environments towards open networks that inte-grate IT and OT. This shift applies IT operation principles to OT environments, such as virtualizing Programmable Logic Controllers and using Artificial Intelligence to increase pro-duction and process efficiency. While there is a huge ef-fort to integrate IT principles, this paper demonstrates that IT/OT convergence remains an underexplored area of re-search, leaving out critical research opportunities for future networking systems. We identify three core challenges: tim-ing constraints, service availability, and changing network traffic characteristics. For each challenge, we provide a con-crete use case that demonstrates early findings and opens up new avenues for research within SIGCOMM.

This section explores the challenge of meeting strict timing requirements (down to 1 µs jitter) in virtualized industrial networks. It highlights how current software stacks and hardware interfaces introduce unpredictable delays and makes a case for new measurement techniques.
1 µs
Jitter requirement for high-speed motion control in manufacturing.
The convergence of IT and OT in industrial networks introduces significant timing challenges. Traditional hardware-based PLCs are designed for deterministic operation, but virtualizing PLCs on general-purpose servers introduces non-deterministic behaviors due to contention in host networks, PCIe latency, and packet processing overheads.

To address these timing challenges, a diagnostic technique called Traffic Reflection is proposed. It uses network taps and a 'reflection point' in the eBPF code to measure nano-second-level jitter and timing drift, providing a first step towards understanding and guaranteeing real-time demands.
This section addresses the crucial need for extreme service availability (≥ 99.9999%) in industrial automation, contrasting it with typical data center reliability. It proposes programmable networks to enhance fault containment and graceful recovery.
99.9999%
Service Availability required for critical industrial automation.
Industrial automation systems, especially for motion control and mobile robots, require extreme service availability, translating to less than 31.5 seconds of downtime per year. This is significantly stricter than typical data center reliability targets.
| Feature | OT Systems | Data Center Networks |
|---|---|---|
| Availability Target | ≥ 99.9999% | Typically minutes of downtime/month |
| Fault Tolerance | Distributed, independent cells | Fiber link reliability varies widely |
| Recovery | Fast switchover (50-300ms) | Not designed for real-time control disruptions |
The InstaPLC approach uses programmable networks to enable seamless switchovers between vPLC pairs without requiring dedicated hardware links, addressing high-availability challenges in virtualized environments by leveraging in-network application logic.
This section examines the emergence of 'never-ending, deterministic micro-flows' from vPLCs, which conflicts with traditional data center traffic engineering optimized for flow completion and throughput. It explores challenges in co-existing with ML workloads.
Microflows
New traffic type with deterministic, never-ending, small packet characteristics.
Industrial networks are characterized by predictable, deterministic traffic with strict latency and jitter constraints, often comprising small, periodic packets. This contrasts sharply with data center traffic, which is diverse and typically optimized for large flows and throughput.
ML-Aware Topologies for Industrial Automation
This case study demonstrates how ML-aware network topologies significantly improve latency for defect detection and object identification in industrial settings compared to traditional IT (Leaf Spine) and OT (Ring) networks. This highlights the need for specialized network designs for converged IT/OT workloads.
