The configuration method provided by the embodiment of the invention can be executed by a configuration device. Fig. 1 is a block diagram illustrating a configuration apparatus according to various embodiments of the present invention.
As shown in fig. 1, the configuration means may include: a processor 11 and a memory 12.
The following describes the components of the configuration device in detail with reference to fig. 1:
the processor 11 may be a CPU, an Application Specific Integrated Circuit (ASIC), or one or more Integrated circuits configured to implement embodiments of the present invention, such as: one or more microprocessors (digital signal processors, DSP for short), or one or more Field Programmable Gate arrays (FPGA for short).
The memory 12 may be a volatile memory (RAM), such as a random-access memory (RAM); or a non-volatile memory (non-volatile memory), such as a read-only memory (ROM), a flash memory (flash memory), a Hard Disk Drive (HDD), or a solid-state drive (SSD); or a combination of the above types of memories for storing the relevant applications and configuration files that implement the configuration method of the present invention.
Specifically, the processor 11 may be configured to obtain a performance index parameter, and configure an attribute of a cache (english: cache) to not perform an allocation operation through the packet parsing module when the obtained performance index parameter is greater than or equal to a preset threshold.
Wherein, the performance index parameter is used for indicating the load condition of the CPU, and the performance index parameter may include any one or a combination of more than one of the following: CPU occupancy rate, cache hit rate, DDR access delay, Instruction number Per Cycle (IPC for short) index.
The processor 11 may be further configured to configure the message parsing module to start the selective message discarding function when the obtained performance index parameter is greater than or equal to the preset threshold, so that the message parsing module discards a message with a low priority in the to-be-processed message.
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Fig. 2 is a flowchart of a configuration method according to an embodiment of the present invention, where the method is applied to a configuration device, and as shown in fig. 2, the configuration method may include the following steps:
201. and acquiring a performance index parameter.
Wherein the performance index parameter is used for indicating the load condition of the CPU. For example, the performance indicator parameter may be a CPU occupancy.
202. And when the performance index parameter is greater than or equal to the preset threshold value, configuring the attribute of the cache not to be subjected to allocation operation through the message analysis module.
Specifically, after the performance index parameter is obtained, whether the performance index parameter is greater than or equal to a preset threshold value or not can be judged, and when the performance index parameter is determined to be greater than or equal to the preset threshold value, the attribute of the cache is configured not to be allocated through the message parsing module, so that the allocation of the cache is stopped, and further, the cache data in the cache is prevented from being frequently swapped in and out.
According to the configuration method provided by the embodiment of the invention, when the acquired performance index parameter is determined to be greater than or equal to the preset threshold value, the attribute of the cache is configured to be not allocated through the message analysis module, so that frequent swapping-in and swapping-out of the cached data in the cache are avoided, the problem that the processor cannot be recovered after the performance of the processor is reduced is solved, the problem of service interruption caused by the fact that the processor is in a low-performance state for a long time can be avoided, and the stability and the robustness of the system are improved.
Fig. 3 is another configuration method provided in the embodiment of the present invention, and as shown in fig. 3, the method may include:
301. the processor obtains a performance index parameter.
302. When the performance index parameter is larger than or equal to the preset threshold value, the processor configures the attribute of the cache not to be distributed through the message analysis module, and configures the message analysis module to start a selective message discarding function, so that the message analysis module discards a message with low priority in the messages to be processed.
After the performance index parameter is obtained, if the processor determines that the obtained performance index parameter is greater than or equal to the preset threshold, it indicates that the processing load of the processor exceeds the maximum processing capacity of the processor, at this time, the processor may configure the attribute of the cache to not perform the allocation operation through the message parsing module, and at the same time, configure the message parsing module to start the selective message discarding function, so that the message parsing module discards a message with a low priority in the messages to be processed, thereby enabling the processor to preferentially process a message with a higher priority, and avoiding that a service with a higher priority is greatly influenced.
It should be noted that, in the embodiment of the present invention, the preset threshold may be set according to requirements of an actual application scenario, and the embodiment of the present invention is not specifically limited herein.
303. And the processor performs service processing on the message corresponding to the message descriptor in the message to be processed according to the message descriptor stored in the cache.
Under the condition that the processor configures the attribute of the cache not to perform allocation operation through the message analysis module and configures the message analysis module to start the selective message discarding function, the processor can preferentially perform service processing on the message corresponding to the message descriptor in the message to be processed according to the message descriptor stored in the cache, and gradually, the performance of the processor can be recovered.
It should be noted that, in the embodiment of the present invention, the execution of steps 301 to 302 and step 303 has no precedence relationship, and the execution order of steps 301 to 302 and step 303 is not specifically limited herein.
In order to process the message normally after the performance of the processor is recovered, the following step 304 may be executed:
304. the processor retrieves the performance indicator parameter.
The processor may be configured to obtain the performance index parameter repeatedly according to a preset time parameter for the processor to periodically obtain the performance index parameter.
If the performance index parameter obtained again in step 304 is smaller than the preset threshold, step 305 is executed, and if the performance index parameter obtained again is still greater than or equal to the preset threshold, which indicates that the processing performance of the processor is still in the low level, step 304 may be repeatedly executed until the performance index parameter obtained again is smaller than the preset threshold.
305. The processor configures the attributes of the cache to perform allocation operations through the message analysis module, and configures the message analysis module to close the selective message discarding function.
When the performance index parameter obtained again is smaller than the preset threshold value, it indicates that the processing load of the processor is lower than the maximum processing capacity of the processor, at this time, the processor may configure the attribute of the cache to perform allocation operation through the message parsing module, configure the message parsing module to close the selective message discarding function, so as to perform normal message processing.
Certainly, when the performance index parameter obtained again is smaller than the preset threshold, and the attribute of the cache is configured to be allocated for performing an allocation operation by the packet parsing module, and after the selective packet discarding function is closed by the configuration packet parsing module, step 301 may be performed again, so that when the processing load of the processor exceeds the maximum processing capacity of the processor again, the performance of the processor may be recovered by performing steps 302 to 305, and normal packet processing is performed.
According to the configuration method provided by the embodiment of the invention, when the acquired performance index parameter is determined to be greater than or equal to the preset threshold value, the attribute of the cache is configured to be not allocated through the message analysis module, so that frequent swapping-in and swapping-out of the cached data in the cache are avoided, the problem that the processor cannot be recovered after the performance of the processor is reduced is solved, the problem of service interruption caused by the fact that the processor is in a low-performance state for a long time can be avoided, and the stability and the robustness of the system are improved.
And when the acquired performance index parameter is determined to be greater than or equal to the preset threshold value, the configuration message analysis module starts the selective message discarding function, so that the problem that the service with higher priority is greatly influenced under the condition that the performance of the processor is low is avoided.
The configuration method provided by the embodiment of the present invention may be applied to most application scenarios in which a CPU forwards a packet, and the embodiment of the present invention takes a typical processing scenario as an example to exemplify the configuration method provided by the present invention. In this scenario, the message parsing module may specifically be a Packet parsing Engine module (Packet part Engine, abbreviated as PPE), and a specific system architecture of this scenario may be as shown in fig. 4, where the system architecture shown in fig. 4 includes: gigabit Ethernet (GE), PPE, a Buffer Management Unit (BMU), a Traffic Management module (TM), DDR, a service edition and a processor. Further, a performance index parameter indicating a load condition of the CPU is taken as an example of the CPU occupancy. Under the system architecture, referring to fig. 4, the specific processing flow of message forwarding is as follows:
step 1: PPE applies for memory Buffer (English: Buffer) to BMU and allocates cache.
Step 2: and the GE interface receives the message sent by the service version and sends the received message to the PPE, and the PPE analyzes the received message to generate a message descriptor.
And step 3: the PPE caches the received message in the buffer applied in the step 1, and stores part of the descriptor related to service processing in the message descriptor in the cache distributed in the step 1.
And 4, step 4: and the processor acquires the message descriptor in the cache and performs service processing according to the acquired message descriptor.
And 5: and the processor sends the message descriptor to the TM after the service processing is finished.
Step 6: and the TM dispatches the message stored in the buffer according to the message descriptor and sends the message to the PPE.
And 7: PPE sends the message to the service board through GE interface.
And 8: the PPE releases the Buffer applied in step 1 to the BMU.
In the process of executing the flow, the processor may obtain the CPU occupancy rate, and determine whether the CPU occupancy rate is greater than or equal to a preset threshold, and when it is determined that the CPU occupancy rate is greater than or equal to the preset threshold, it indicates that the processing load of the processor exceeds the maximum processing capacity of the processor, at this time, the processor may configure the attribute of the cache to not perform allocate operation through the PPE, and preferentially perform service processing on the packet corresponding to the packet descriptor stored in the cache, and further, when it is determined that the CPU occupancy rate is greater than or equal to the preset threshold, the processor configures the PPE to start a selective packet discarding function, so that the PPE discards a packet with a low priority in the packets to be processed, so that the processor may preferentially process a packet with a higher priority, and gradually, the performance of the processor may be gradually restored.
Further, in order to process the message normally after the performance of the processor is recovered, the processor may obtain the CPU occupancy rate again, and configure the attribute of the cache to perform allocate operation through the PPE when the CPU occupancy rate is smaller than the preset threshold value, and configure the PPE to close the selective message discarding function.
The processor may repeat the above process to be able to recover when the performance of the processor degrades.
