Abstract
Disclosed are communication methods in a divided vehicle network. An operation method of a first end node includes: generating a frame; and transmitting the frame to a switch connected to the first end node. A source internet protocol (IP) address of the frame is set to an IP address of the first end node, a destination IP address of the frame is set to an IP address of a second end node belonging to a second domain in the vehicle network, a source medium access control (MAC) address of the frame is set to a MAC address of the first end node, and a destination MAC address of the frame is set to a MAC address of a gateway supporting inter-domain communications.
Claims20
An operation method of a first end node belonging to a first domain in a vehicle network, the method comprising:
- generating a frame;
- and
- transmitting the frame to a switch connected to the first end node,
- wherein a source internet protocol (IP) address of the frame is set to an IP address of the first end node, a destination IP address of the frame is set to an IP address of a second end node belonging to a second domain in the vehicle network, a source medium access control (MAC) address of the frame is set to a MAC address of the first end node, and a destination MAC address of the frame is set to a MAC address of a gateway supporting inter-domain communications.
An operation method of a switch in a vehicle network, the method comprising:
- receiving a frame from a first end node belonging to a first domain in the vehicle network;
- identifying a communication node indicated by a destination medium access control (MAC) address of the frame;
- and
- transmitting the frame to a gateway supporting inter-domain communications when the identified communication node is the gateway.
An operation method of a gateway in a vehicle network, the method comprising:
- receiving a frame from a switch;
- changing a destination medium access control (MAC) address of the frame to a MAC address of an end node indicated by a destination internet protocol (IP) address of the frame when the frame is used for communication between end nodes belonging to different domains;
- and
- transmitting the frame having the changed destination MAC address to the switch.
