The present disclosure provides methods for releasing a reserved resource in a network. An operation method performed in a first communication node of a vehicle network includes generating a first frame including identification information of a stream transmitted through a reserved resource and a first indicator instructing to release the reserved resource; and transmitting the first frame to a second communication node.

Method of releasing resource reservation in network

A time synchronization method performed by a communication node in a vehicle includes: receiving, from a road side unit (RSU), a first frame including time information of a first domain to which the RSU belongs; setting a time of the vehicle based on a time indicated by the time information of the first domain; and transmitting a second frame including the time information of the vehicle.

Method for time synchronization of domain based on time information of vehicle

A method for configuring a communication path comprises: receiving a first frame requesting to configure a communication path through which a stream is transmitted; configuring a table of the first communication node based on information included in the first frame, when a second frame having a same stream identifier as a stream identifier of the first frame is not received; increasing a hop count of the first frame; and transmitting the first frame including the increased hop count.

Method for configuring stream communication path in network

An operation method of a switch apparatus in an Ethernet-based vehicle network, includes: receiving a first frame including original data from an end node; generating a second frame including the original data; duplicating the original data to generate duplicated data; and generating a third frame including the duplicated data and an indicator indicating that the third frame includes the duplicated data.

Method of transmitting data based on priorities in network

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.
