Abstract: Operation methods of a first communication node in a network, in particular, an Ethernet-based vehicle network, include: transmitting, by the first communication node to at least one communication node which is connected to the first communication node, a first frame requesting state information of a physical layer between the first communication node and the at least one communication node; receiving, by the first communication node from the at least one communication node, a second frame in response to the first frame; and identifying, by the first communication node, a state of the physical layer based on the second frame when the second frame is received.

Abstract: A method for processing a SOME/IP stream through interworking with Audio Video Bridging (AVB) in a server includes determining a transmission scheme for the SOME/IP stream through a SOME/IP service discovery procedure and generating an InitialEvent message and transmitting the generated InitialEvent message to a client according to the determined transmission scheme. If the determined transmission scheme is L2-Frame, the SOME/IP stream is transmitted through a layer 2 of AVB. Therefore, a SOME/IP stream, the QoS of which is guaranteed through interworking with AVB, may be provided.

Abstract: Disclosed are time synchronization methods for domains based on time information of a vehicle. A time synchronization method performed by a first end node belonging to a first domain of a vehicle includes: receiving a first frame including time information from the vehicle; changing the first end node to a grand master node of the first domain when the time information indicates a time of a universal time domain; and synchronizing a time of the grand master node with the time of the universal time domain.

Abstract: The present disclosure relates to a data communication system, a data communication method, a server, and a vehicle. The data communication system may include: a data transmitting apparatus configured to generate a first hash value using one of a plurality of previous hash values as a first seed number, to encrypt data using the first hash value, and to transmit the encrypted data; and a data receiving apparatus configured to receive the data transmitted from the data transmitting apparatus, to separate the first hash value generated by the data transmitting apparatus from the data, to calculate a second hash value using one of the plurality of previous hash values as a second seed number, and to determine a validity of the data based upon whether the calculated second hash value coincides with the first hash value separated from the data.

Abstract: An operation method of a first communication node includes: measuring a magnitude of a current supplied to a second communication node through a data line in the vehicle network; comparing the measured magnitude of the current with a predetermined threshold value; generating an address resolution protocol (ARP) frame including fault-related information when the second communication node is determined to be in a fault state based on a result of the comparison; and transmitting the ARP frame.
