摘要：The widespread clock synchronization standard, IEEE 1588, is purely master-slave based. The inherent disadvantage is that a failure of the master requires the election of a new one, during which the network nodes cannot be synchronized. The present paper proposes a compatible extension to the standard introducing architecture for fault-tolerant and seamless distribution of time information. In this paper the protocol is implemented using RTOS in a LAN with processor as one node. The processor having real time clock and is programmed for the synchronization between systems. The processor is the grand master clock which is going to generate clock pulses for all other nodes in the LAN. All the other systems in LAN will have a software stack that incorporates the full specification and functionality of the Precision Clock Synchronization Protocol along with a Timing Table and File Table. After the introduction of the architecture the common application of Ethernet is treated to outline the problems arising from this network type. The proposed solution significantly increases the accuracy of the synchronized network in case of failures and additionally provides backup strategies in case of network problems. Network Area Storage (NAS) is implemented as an application between the systems where communication is carried out using PTP.
