Abstract: Disclosed is a method for controlling a message over a heterogeneous network. The method includes receiving a first message from a first network, generating a plurality of second messages (a “plurality of fragmented messages”) each header including an arbitration field by performing fragmentation on the first message, and increasing priority of at least one remaining fragmented message by controlling the arbitration field of the at least one remaining fragmented message if the transmission of a first fragmented message over a second network is successful. An apparatus for performing the method includes a reception message processing unit, a transmission message processing unit, a transmission network sensing unit, and a message transmission continuity management unit. Accordingly, a method and apparatus for controlling a message over a heterogeneous network can be simplified, message transmission latency can be prevented, and a message transmission sequence can be maintained.

Abstract: An apparatus and method for supporting a precision time synchronization protocol of a stealth clock type are provided. The method may be performed by a stealth clock follower device and may include transmitting a sync message received from a neighbor device to an end-follower device, receiving a delay-request message from the end-follower device, and updating a residence time in a correction field of the received delay-request message. The method may also include transmitting the updated delay-request message to a leader device, receiving a delay-response message from the leader device, and performing time synchronization based on a time of the leader device by using an ingress time of the sync message, an egress time of the updated delay-request message, and time information contained in the sync message and the delay response-message. The method may further include transmitting the delay-response message to the end-follower device for time-synchronization.
