Method, device and computer program product for data processing

1. A method of data processing, comprising:

receiving a data packet related to a service;

determining whether predefined configuration information indicates a priority of the service; and

in response to the configuration information indicating the priority of the service, adding an indication of the priority into the data packet;

wherein adding an indication of the priority into the data packet comprises:

comparing the priority with a threshold priority;

in response to the priority being higher than the threshold priority, determining a first predetermined field in the data packet as an insertion position in the data packet to which the indication is added; and

in response to the priority being lower than or equaling to the threshold priority, determining a second predetermined field in the data packet as the insertion position, the second predetermined field being different from the first predetermined field.

2. The method of claim 1 , wherein

the first predetermined field is a type-of-service field in an Internet Protocol (IP) header of the data packet.

3. The method of claim 1 , further comprising:

in response to receiving the data packet, verifying an IP header of the received data packet to determine a validity of the received data packet.

4. The method of claim 1 , further comprising:

initiating a given transmission strategy based on the indication of the priority.

5. The method of claim 1 , wherein one or more of the receiving, determining and adding steps are performed by a proxy component.

6. The method of claim 5 , wherein the proxy component is configured as part of an inter-service communication protocol.

7. An electronic device for data processing, comprising:

a processor; and

a memory comprising computer program instructions stored thereon, the processor executing the computer program instructions in the memory to control the electronic device to perform acts comprising:

receiving a data packet related to a service;

determining whether predefined configuration information indicates a priority of the service; and

in response to the configuration information indicating the priority of the service, adding an indication of the priority into the data packet;

wherein adding an indication of the priority into the data packet comprises:

comparing the priority with a threshold priority;

in response to the priority being higher than the threshold priority, determining a first predetermined field in the data packet as an insertion position in the data packet to which the indication is added; and

in response to the priority being lower than or equaling to the threshold priority, determining a second predetermined field in the data packet as the insertion position, the second predetermined field being different from the first predetermined field.

8. The electronic device of claim 7 , wherein

the first predetermined field is a type-of-service field in an IP header of the data packet.

9. The electronic device of claim 7 , wherein the acts further comprise:

in response to receiving the data packet, verifying an IP header of the received data packet to determine a validity of the received data packet.

10. The electronic device of claim 7 , wherein the acts further comprise:

initiating a given transmission strategy based on the indication of the priority.

11. The electronic device of claim 7 , wherein a proxy component performs one or more of the acts.

12. The electronic device of claim 11 , wherein the proxy component is configured as part of an inter-service communication protocol.

13. The electronic device of claim 7 , wherein the second predetermined field is another type-of-service field in the IP header of the data packet.

14. A computer program product comprising a non-transitory computer storage medium having stored therein machine-executable instructions which, when executed by a machine, cause the machine to perform acts comprising:

receiving a data packet related to a service;

determining whether predefined configuration information indicates a priority of the service; and

in response to the configuration information indicating the priority of the service, adding an indication of the priority into the data packet;

wherein adding an indication of the priority into the data packet comprises:

comparing the priority with a threshold priority;

in response to the priority being higher than the threshold priority, determining a first predetermined field in the data packet as an insertion position in the data packet to which the indication is added; and

in response to the priority being lower than or equaling to the threshold priority, determining a second predetermined field in the data packet as the insertion position, the second predetermined field being different from the first predetermined field.

15. The computer program product of claim 14 , wherein

the first predetermined field is a type-of-service field in an IP header of the data packet.

16. The computer program product of claim 14 , wherein the acts further comprise:

in response to receiving the data packet, verifying an IP header of the received data packet to determine a validity of the received data packet.

17. The computer program product of claim 14 , further comprising:

initiating a given transmission strategy based on the indication of the priority.

18. The computer program product of claim 14 , wherein a proxy component performs one or more of the acts.

19. The computer program product of claim 18 , wherein the proxy component is configured as part of an inter-service communication protocol.

20. The computer program product of claim 14 , wherein the second predetermined field is another type-of-service field in the IP header of the data packet.
