Architectural Layers & Regulatory Standards

Physical & Time-Synchronized Layer (IEEE 802.1AS Generalized PTP / IEEE 802.1Qbv Shaper): Sub-microsecond clock synchronization and bandwidth reservation across medical Ethernet switches.
Safety-Critical Transport (IEC 61784-3 Functional Safety / UDP Multicast): Dual-rail redundant communication with cryptographic cyclic redundancy checks.
Service-Oriented Device Connectivity (IEEE 11073-10207 BICEPS / Web Services Eventing): BICEPS domain information model providing dynamic medical device capability discovery.
Application Alarm & Control Integration (IEC 60601-1-8 Alarm Systems / ISO 80601-2-12 Ventilators): Synchronized physiological alarm escalation and remote surgical robot actuator interlocks.

Key Metrics: < 1 ms (Deterministic Message Delivery) | Zero Loss (Bounded Packet Jitter) | 1 µs (Clock Synchronization Accuracy) | SDC Ready (IEEE 11073-10207 Conformance)

手術室におけるレイテンシとベンダーロックインの排除

Closed-loop interoperability between operating room equipment requires deterministic packet guarantees. SaMDProtocol establishes service-oriented device connectivity over Ethernet, replacing proprietary serial cables with open, verified medical standards.
