5. The operation method according to claim 2 , wherein the second indicator is included in the reserved field, and when the type of the data included in the payload is text, the second indicator indicates the encoding scheme applied to the data which are text data.
6. The operation method according to claim 2 , wherein the second indicator is included in the reserved field, and when the type of the data included in the payload is image, the second indicator indicates the encoding scheme applied to the data which are image data.
7. The operation method according to claim 2 , wherein the third indicator is included in the reserved field.
8. An operation method of a first communication node in an Ethernet-based vehicle network, comprising:
receiving a data message including data from a second communication node belonging to the Ethernet-based vehicle network;
identifying a purpose of the data message based on a first indicator included in the data message;
identifying a type of data which is included in a payload of the data message based on the first indicator;
identifying an encoding scheme applied to the data based on the type of the data and a second indicator included in the data message;
decoding the data included in the data message using a decoding scheme corresponding to the encoding scheme; and
when a decoding operation of the data is completed, transmitting an acknowledge message based on a requirement of the acknowledge message,
wherein the data message further comprises a third indicator indicating a resolution of the data which are image data, and a fourth indicator requesting transmission of the acknowledge message.
9. The operation method according to claim 8 , wherein the data message includes an Ethernet header, an internet protocol (IP) header, a user datagram protocol (UDP) header, a message identifier (ID) field, a length field, a flag field, a reserved field, a sequence number field, and a payload including the data.
10. The operation method according to claim 9 , wherein the first indicator is included in the message ID field, and indicates that the type of the data included in the payload is text or image.
11. The operation method according to claim 9 , wherein the first indicator is included in the flag field, and indicates that the type of the data included in the payload is text or image.
12. The operation method according to claim 9 , wherein the second indicator is included in the reserved field, and when the type of the data included in the payload is text, the second indicator indicates the encoding scheme applied to the data which are text data.
13. The operation method according to claim 9 , wherein the second indicator is included in the reserved field, and when the type of the data included in the payload is image, the second indicator indicates the encoding scheme applied to the data which are image data.
14. The operation method according to claim 9 , wherein the third indicator is included in the reserved field.
15. A first communication node in an Ethernet-based vehicle network comprising a processor and a memory storing at least one instruction executed by the processor, wherein the at least one instruction is configured to:
generate a data message including data when there is data to be transmitted to a second communication node belonging to the Ethernet-based vehicle network;
transmit the data message to the second communication node; and
receive an acknowledge message indicating a result of a reception of the data message;
wherein the data message further comprises a first indicator indicating a purpose of the data message and a type of data which is included in a payload of the data message, a second indicator indicating an encoding scheme applied to the data, a third indicator indicating a resolution of the data which are image data, and a fourth indicator requesting transmission of the acknowledge message.
16. The first communication node according to claim 15 , wherein the data message includes an Ethernet header, an internet protocol (IP) header, a user datagram protocol (UDP) header, a message identifier (ID) field, a length field, a flag field, a reserved field, a sequence number field, and a payload including the data.
