Roadmap

We will continuously polish NG Gateway into a Stable, Reliable, Operable, Extensible industrial-grade IoT gateway product.

---

Milestone M0: Stable for Launch

• Reliable Operation and Performance Baseline
  • Stability: Stable operation and automatic recovery under weak network/jitter/high load scenarios
  • Performance: Establish official stress test baseline (Point Scale × Period × Latency), and continuously optimize throughput/latency
• Observability and Troubleshooting (Better Usability)
  • Metrics and Dashboard perfection (Southward Channel / Northward App / Backpressure Queue / Resource)
  • Troubleshooting Toolbox: Connection Test, Write Point/Action Debug, Temporary Log Level (Auto Rollback) etc.
• Configuration and Change Governance
  • Configuration Change Audit (Who changed what, when, impact scope)
  • Configuration Snapshot and Rollback (Reduce field change risk)

Milestone M1: Weak Network Reliable Delivery + Controllable Degradation

• Offline Resume (WAL + Replay)
  • Try to guarantee critical data integrity delivery under weak network/disconnect/power loss scenarios
  • Support disk buffer, quota and cleanup strategy, replay rate limiting and realtime link isolation
• Queue Full Intelligent Degradation (Unified Strategy)
  • Degrade in a controllable way when downstream congested, prioritize protecting gateway stability and critical business
  • Support strategies like TTL, Sampling, Merge by Last, Priority Retention (Alarm/Control first)

Milestone M2: North/South Ecosystem Extension + Productization Governance

Southward Ecosystem (Southward Drivers)

• Enhance Existing Drivers (Supported, but will continuously optimize)
  • Modbus RTU/TCP: Batch collection planning, performance optimization, diagnostic capability enhancement
  • Siemens S7: More models/more data types, fault tolerance and field troubleshooting enhancement
  • IEC 60870-5-104: Stronger fault tolerance, event/telecontrol scenario enhancement
  • DL/T 645 (1997/2007): More meter and exception scenario coverage
  • OPC UA Client: Subscription/Collection strategy, stability and diagnosis enhancement
  • Serial (RS-232/485), TCP/UDP: Connection governance, timeout and retry strategy optimization
• New Southward Drivers (Planned extension, push by demand priority)
  • Industrial Automation/PLC: EtherNet/IP (CIP), Mitsubishi MC, Omron FINS, Profinet (Evaluation)
  • Power/Energy: IEC 61850 (MMS/Report; GOOSE Evaluation), DNP3
  • Building/Meter/Bus: BACnet, M-Bus / wM-Bus, CAN / CANopen
• General Capability Continuous Enhancement: Unified Timeout/Retry/Backoff, Batch Planning, Concurrency Capability, Field Diagnostic Toolchain

Northward Ecosystem (Northward Plugins)

• Enhance Existing Plugins (Supported, but will continuously optimize)
  • ThingsBoard: Connection stability, uplink/downlink capability, diagnostic experience continuous enhancement
  • Kafka / Pulsar: Batch/Compression, Backpressure and Retry strategy, Throughput and Latency optimization
  • OPC UA Server: Data model mapping, write link and observability enhancement
• New Northward Plugins (Planned extension, push by demand priority)
  • IoT Platform/Cloud Vendor: AWS IoT Core, Azure IoT Hub, Aliyun IoT / Tencent Cloud IoT / Huawei Cloud IoTDA (On demand)
  • Messaging and Streaming: MQTT v5, NATS / JetStream, RabbitMQ (AMQP), Redis Streams
  • Data Storage/Analytical Destination: InfluxDB, TimescaleDB / PostgreSQL, ClickHouse, Elasticsearch / OpenSearch, S3 / MinIO (By scenario)
• Higher Throughput Encoding and Transmission
  • Binary payload (Protobuf/Avro etc.) to reduce bandwidth and CPU (Applicable to high frequency/large scale points)
  • Richer mapping and protocol adaptation capabilities (Improve flexibility without sacrificing performance)

Productization Governance

• Plugin/Driver Governance
  • Compatibility and Upgrade Strategy (Version constraint clear, upgrade predictable)
  • Gray Release and Rollback (Quick rollback on issue)
  • Signature and Source Verification (Supply Chain Security)
• Security Enhancement
  • Management Plane Security Baseline Continuous Hardening (Permission, Audit, Sensitive Information Protection)
  • TLS/mTLS Capability Enhancement (Step-by-step coverage by scenario)

Iteration Direction We Long Adhere To

• Performance First: High throughput, low latency, low resource footprint
• Stability First: Weak network tolerance, recoverable, explainable
• Operability First: Metrics/Logs/Diagnostics closed loop, reduce field cost
• Ecosystem First: Long-term extension and engineering delivery of Southward Drivers + Northward Plugins
