Abstract
An operation method of a first communication node comprises: receiving a first frame from a second communication node; obtaining a destination address of the first frame; and transmitting a second frame including an indicator for indicating an occurrence of an error in the first frame to a communication node corresponding to a source address of the first frame, when a port corresponding to the destination address does not exist in a routing table.
Claims11
An operation method of a first communication node in an Ethernet-based vehicle network, the operation method comprising:
- receiving a first frame from a second communication node;
- obtaining a destination address of the first frame without performing an error check operation on the first frame;
- transmitting the first frame through a port corresponding to the destination address based on a routing table of the first communication node;
- receiving a second frame including a first indicator indicating an occurrence of an error in the first frame from a third communication node receiving the first frame;
- transmitting the second frame to a fourth communication node corresponding to a source address of the first frame;
- receiving, from the third communication node, a third frame including a second indicator requesting to perform the error check operation;
- receiving a fourth frame from the second communication node;
- and
- performing the error check operation on the fourth frame.
An operation method of a first communication node in an Ethernet-based vehicle network, the operation method comprising:
- receiving, from a second communication node, a first frame on which an error check operation has not been performed in the second communication node;
- performing the error check operation on the first frame;
- transmitting, to a third communication node corresponding to a source address of the first frame, a second frame including a first indicator indicating an occurrence of an error in the first frame when the first frame has the error;
- and
- transmitting, to the second communication node, a third frame including a second indicator requesting to perform the error check operation.
