The capabilities of system integration technologies impact electronics platform complexity, software design methodology, application design, system integration, reuse, upgrades, obsolescence management and certification for time-, mission-, and safety-critical applications. The right system integration infrastructure with deterministic high-bandwidth Ethernet enables design of less complex software-centric systems at lower lifecycle cost. New Quality Of Service (QoS) enhancements and protocol standards such as TTEthernet (SAE AS6802), guarantee strictly deterministic computing and networking performance and satisfy requirements of backplane and backbone applications in aerospace, defense, automotive, energy production and industrial systems.
