Embodiment 1
[0026] An embodiment of the present invention provides a method for processing packets in a power SDN controller, which is used for a flow table matching module configured in the power SDN controller, such as figure 1 As shown, the method for processing messages in the power SDN controller includes:
[0027] Step S1: The flow table matching module judges whether the packet to be matched is a target packet that needs to be processed first, and the target packet is a control packet and / or a protection packet specified in the IEC61850 protocol. In the embodiment of the present invention, the control-type and protection-type message formation and processing methods specified in the IEC61850 protocol that require priority processing are made into a flow table matching module and integrated into the SDN controller software. The switch will packet-in the packet that needs to be matched to the SDN controller, and the flow table matching module judges whether the packet to be matched i...
Embodiment 2
[0039] An embodiment of the present invention provides a flow table matching module configured by a power SDN controller, such as Figure 4 As shown, it includes: judging sub-module 1, which is used to judge whether the message to be matched is a target message that needs to be processed first, and the target message is a control message and / or a protection message specified in the IEC61850 protocol; the determination sub-module 2. It is used to determine the transmission strategy for transmitting the target message when it is determined that the message to be matched is the target message that needs to be processed first; the control sub-module 3 is used to control the switch to transmit the target message according to the transmission policy .
[0040] The flow table matching module configured by the electric power SDN controller provided by the present invention makes the flow table matching module into a flow table matching module by forming and processing the control clas...
Embodiment 3
[0042] The embodiment of the present invention also provides a computer device, such as Figure 5 As shown, the device terminal may include a processor 51 and a memory 52, wherein the processor 51 and the memory 52 may be connected via a bus or in other ways, Figure 5 Take connection via bus as an example.
[0043] The processor 51 may be a central processing unit (Central Processing Unit, CPU). Processor 51 can also be other general processors, digital signal processor (Digital Signal Processor, DSP), application specific integrated circuit (Application Specific Integrated Circuit, ASIC), field programmable gate array (Field-Programmable Gate Array, FPGA) or Other chips such as programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, or combinations of the above-mentioned types of chips.
[0044] As a non-transitory computer-readable storage medium, the memory 52 can be used to store non-transitory software programs, non-transito...
