Abstract:
1. A time synchronization system, comprising: a master comprising: a plurality of slaves configured to send a first packet whose destination is the first IP address and a second packet whose destination is the second IP address to the master, wherein the second packet is a packet for time synchronization between the master and one of the slaves, and the first packet is a data packet different from the second packet; and a relay provided between the slaves and the master to relay the first packet and the second packet sent from the slaves to the master, the relay being configured to send the first packet to the main processor and to send the second packet to the time synchronization processor, and wherein the main processor is configured to receive the first packet from the relay and perform a certain process on the first packet; and the time synchronization processor is configured to receive the second packet from the relay and perform a time synchronization process between the master and said one of the slaves based on the second packet.
