Abstract

According to one exemplary embodiment, a method for orchestrating a flow of a packet through a software-defined network (SDN) switch is provided. The method may include determining at least one available service associated with the SDN switch. The method may also include receiving the packet at an input port associated with the SDN switch, wherein the packet has a destination value and a packet type. The method may then include generating a flow entry based on the at least one available service and the packet type, wherein the flow entry has a plurality of entry characteristics and an action. The method may further include selecting the flow entry based on matching the plurality of entry characteristics to the destination value and the packet type. The method may also include performing the action associated with the selected flow entry.

Claims

1. A method for orchestrating a flow of a packet through a software-defined network (SDN) switch, the method comprising:

determining at least one available service associated with the SDN switch;

receiving the packet at an input port associated with the SDN switch, wherein the packet has a destination value and a packet type;

generating a flow entry based on the at least one available service and the packet type, wherein the flow entry has a plurality of entry characteristics and an action;

selecting the flow entry based on matching the plurality of entry characteristics to the destination value and the packet type; and

performing the action associated with the selected flow entry.

2. The method of claim 1, wherein the plurality of entry characteristics comprises a destination field and an input field.

3. The method of claim 2, wherein matching the plurality of entry characteristics to the destination value and the packet type comprises matching the input field of the flow entry to the input port, and matching the destination field of the flow entry to the destination value associated with the packet.

4. The method of claim 1, wherein the action comprises sending the packet out an output port associated with the SDN switch.

5. The method of claim 4, wherein the sending the packet out an output port associated with the SDN switch comprises sending the packet to a service within the at least one available service.

6. The method of claim 5, wherein the service sends a result code based on the packet.

7. The method of claim 6, further comprising:

receiving the result code from the service; and

generating a new flow entry based on the received result code.

8. A computer system for orchestrating a flow of a packet through a software-defined network (SDN) switch, comprising:

one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage medium, and program instructions stored on at least one of the one or more tangible storage medium for execution by at least one of the one or more processors via at least one of the one or more memories, wherein the computer system is capable of performing a method comprising;

determining at least one available service associated with the SDN switch;

receiving the packet at an input port associated with the SDN switch, wherein the packet has a destination value and a packet type;

generating a flow entry based on the at least one available service and the packet type, wherein the flow entry has a plurality of entry characteristics and an action;

selecting the flow entry based on matching the plurality of entry characteristics to the destination value and the packet type; and

performing the action associated with the selected flow entry.

9. The computer system of claim 8, wherein the plurality of entry characteristics comprises a destination field and an input field.

10. The computer system of claim 9, wherein matching the plurality of entry characteristics to the destination value and the packet type comprises matching the input field of the flow entry to the input port, and matching the destination field of the flow entry to the destination value associated with the packet.

11. The computer system of claim 8, wherein the action comprises sending the packet out an output port associated with the SDN switch.

12. The computer system of claim 11, wherein the sending the packet out an output port associated with the SDN switch comprises sending the packet to a service within the at least one available service.

13. The computer system of claim 12, wherein the service sends a result code based on the packet.

14. The computer system of claim 13, further comprising:

receiving the result code from the service; and

generating a new flow entry based on the received result code.

15. A computer program product for orchestrating a flow of a packet through a software-defined network (SDN) switch, comprising:

one or more computer-readable storage medium and program instructions stored on at least one of the one or more tangible storage medium, the program instructions executable by a processor, the program instructions comprising;

program instructions to determine at least one available service associated with the SDN switch;

program instructions to receive the packet at an input port associated with the SDN switch, wherein the packet has a destination value and a packet type;

program instructions to generate a flow entry based on the at least one available service and the packet type, wherein the flow entry has a plurality of entry characteristics and an action;

program instructions to select the flow entry based on matching the plurality of entry characteristics to the destination value and the packet type; and

program instructions to perform the action associated with the selected flow entry.

16. The computer program product of claim 15, wherein the plurality of entry characteristics comprises a destination field and an input field.

17. The computer program product of claim 16, wherein matching the plurality of entry characteristics to the destination value and the packet type comprises matching the input field of the flow entry to the input port, and matching the destination field of the flow entry to the destination value associated with the packet.

18. The computer program product of claim 15, wherein the action comprises sending the packet out an output port associated with the SDN switch.

19. The computer program product of claim 18, wherein the sending the packet out an output port associated with the SDN switch comprises sending the packet to a service within the at least one available service.

20. The computer program product of claim 19, wherein the service sends a result code based on the packet.
