Method and device of performing time synchronization

A method of performing time synchronization in a 10 megabits/second baseband signaling over a single twisted pair for short reach (10BASE-T1S) network when a master of the network is a coordinator of time synchronization based on precise time protocol (PTP), the method comprising:

• periodically broadcasting, by the coordinator, a beacon as a Sync message and storing a transmission time (t1);
• storing, by one or more followers receiving the beacon, reception times (t2) of the beacon;
• transmitting at times (t3), by the one or more followers, Req messages;
• broadcasting, by the coordinator receiving the Req messages, one Resp message including the transmission time (t1) of the beacon and reception times (t4) of the Req messages;
• and
• calculating, by the one or more followers receiving the transmission time (t1) of the Sync message and the reception times (t4) of the Req messages, time offsets between the followers and the coordinator.

A precise time protocol (PTP) coordinator for performing PTP-based time synchronization in an Ethernet network, the PTP coordinator comprising:

• a clock configured to function as a master clock in a network;
• a controller configured to perform PTP messaging using symbols;
• and
• a transceiver configured to transmit and receive PTP messages to and from one or more followers in accordance with an instruction of the controller.

A precise time protocol (PTP) follower for performing PTP-based time synchronization in an Ethernet network, the PTP follower comprising:

• a clock configured to provide a reference time point for operations of internal components;
• a controller configured to perform PTP messaging using a symbol;
• and
• a transceiver configured to transmit and receive PTP messages to and from a coordinator in accordance with an instruction of the controller.
