摘要: The very popular Precision Time Protocol (PTP or IEEE 1588) is widely used to synchronize distributed systems with high precision. underlying principle a master/slave concept based on the regular exchange of synchronization messages. This paper investigates an approach enhance PTP fault tolerance and overcome transient deterioration accuracy during recovery from master failure. To this end, proposed where group masters negotiates fault-tolerant agreement system-wide time transparently synchronizes associated 1588 slaves. Experimental verification basis Ethernet implementation shows that feasible indeed improves overall in terms tolerance.
