A Reliable and Self-Aware Clock for reference time failure detection in internal synchronization environment

摘要: A reliable source of time is a fundamental requirement for safety critical applications. For this class applications, synchronization protocols like the IEEE1588 standard, can be adopted. This type was designed to achieve very precise clock synchronization, but they may not sufficient ensure whole system. example an instability local oscillator reference node could influence quality all nodes. In recent years new software clock, Reliable and Self-Aware Clock (R&SAClock), which estimate through statistical analysis, developed tested. paper describe evaluate design protocol timing failure detection internal based on revised version R&SAClock suitably modified cross exploit information among nodes
