SAE International’s AS-2 Embedded Computing Systems Committee has completed a new industry standard that establishes Ethernet as a deterministic networking technology for time-, safety-, and mission-critical embedded systems and critical infrastructure applications. The new standard, “SAE AS6802 – Time-Triggered Ethernet” can be downloaded from the SAE International website.
With SAE AS6802, critical command and control systems, audio/video, and standard LAN applications can safely coexist in one network, without the limitations found in other real-time Ethernet technologies. By using capabilities described in SAE AS6802, Ethernet networks can efficiently and natively handle both synchronous and asynchronous communication.
SAE AS6802 describes Layer 2 Quality-of-Service (QoS) enhancements for Ethernet. Network devices implementing this protocol service can extend Ethernet capabilities by providing distributed fault-tolerant synchronization, robust TDM-style bandwidth partitioning, and synchronous communication with fixed latency and micro seconds-jitter.
SAE AS6802 capabilities are currently being used in Ethernet-based architectures for avionics, vetronics, and energy production applications. This standard is used to design robust, less complex distributed systems and architectures tolerant to faults, at lower lifecycle cost.
SAE International’s AS-2 Embedded Computing Systems Committee addresses all facets of embedded computing systems – design, maintenance, and in-service experience. The committee is part of SAE International’s Avionic Systems Group, which develops some of the key system architecture, design and networking standards, reports, and recommended practices for commercial and military avionics.
