An operation method of a first communication node in an Ethernet-based vehicle network includes identifying a link status between the first communication node and each of a plurality of communication nodes included in the vehicle network; receiving a first frame from a second communication node whose link status is normal among the plurality of communication nodes; identifying a first time difference between a local time of the first communication node and a time stamp of the first frame; and determining a synchronization error between the first communication node and the second communication node based on the first time difference.
