It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

Those skilled in the art will appreciate that the invention may be practiced without some specific details. In some instances, methods, means, and components that are well known to those skilled in the art are not described in detail in order to facilitate the invention.

The inventors of the present invention have found that when the network traffic is huge, the related technology frequently performs interrupt processing and switching, and once the interrupt load exceeds the maximum lossless forwarding rate, the CPU cannot Respond to other tasks, causing an interrupted livelock. At the same time, if the previous packet is currently being processed, the interrupt that is sent when the next packet arrives may interrupt the previous process. This frequent interruption makes the previous data packets unable to be processed effectively. As the data packets continue to flow in, the buffer queues are filled and the packets are lost.

For the above problem, in the embodiments of the present invention, the identifier of the network device in the polling queue is obtained, and the number of data packets corresponding to the network device is obtained according to the identifier of the network device; and the number of data packets corresponding to the network device is determined. Whether the number of data packets corresponding to the network device is greater than the preset number, and processing the preset number of data packets in the data packet corresponding to the corresponding network device.

The following description will be made in conjunction with specific embodiments.

Example 1

FIG. 1 is a flowchart of a method for processing network data reception according to an embodiment of the present invention. As shown in FIG. 1, the method includes:

In step S1, the identifier of the network device in the polling queue is obtained, and the number of data packets corresponding to the network device is obtained according to the identifier of the network device.

Specifically, the network device is a peripheral device connected to the CPU, and may be a network card or the like. When the first packet arrives at the network device, the network device sends an interrupt request to the CPU. The ID of the network device that receives multiple packets is stored in the polling queue.

The network device stores the received data packet in a register corresponding to the network device. When the CPU acquires the identifier of the network device in the polling queue, the network device obtains the number of data packets corresponding to the network device from the corresponding register.

In step S2, it is determined whether the number of data packets corresponding to the network device is greater than a preset value P.

The preset value P may be preset according to an empirical value, or may be calculated according to a current network state.

Step S3, if the number of data packets corresponding to the network device is greater than a preset value P, The P packets in the data packet corresponding to the network device (that is, the network device whose corresponding number of packets is larger than the preset value P) are processed.

The embodiment of the present invention obtains the identifier of the network device in the polling queue, and when the number of data packets corresponding to the network device is greater than the preset value P, processes P data packets in the data packet corresponding to the network device, and adopts The processing method of the polling mode greatly reduces the interrupt overhead, and avoids packet loss by setting the number of processing packets once.

Optionally, before step S1, the method includes:

Step S01, receiving a data packet sent by the network device and an interrupt request;

Step S02: Register the identifier of the network device into the polling queue according to the interrupt request.

Specifically, the polling queue stores an identifier of a plurality of network devices that receive the data packet.

After registering the identity of the network device into the polling queue, the network device turns off the reception interrupt.

Therefore, by receiving the data packet sent by the network device and the interrupt request, registering the identifier of the network device in the polling queue according to the interrupt request, and adopting a polling manner to reduce the interruption. The overhead guarantees the integrity of the data and avoids packet loss.

Optionally, after step S2, the method further includes:

Step S4: If the number of data packets corresponding to the network device is less than a preset value P, process all data packets corresponding to the network device;

In step S5, the identifier of the network device whose number of data packets is less than a preset value P is deleted in the polling queue.

Specifically, when the number of data packets corresponding to the network device is less than the preset value P, the CPU may process the data packet at one time during processing. After all the data packets corresponding to the network device in the polling queue are processed, the identifier of the network device is deleted in the polling queue.

More specifically, after step S3 or S5, the next network device in the polling queue is acquired. The identification of the above steps is repeated until there is no identifier for the network device in the polling queue.

Therefore, when the number of data packets corresponding to the network device is less than the preset value P, all the data packets are processed, and the network device whose number of data packets is less than the preset value P is deleted in the polling queue. The identification, using the polling method, greatly reduces the interrupt overhead, and avoids packet loss by setting the number of processing packets once.

2 is a flowchart of a method for processing network data reception according to another embodiment of the present invention. The steps of the same reference numerals in FIG. 2 and FIG. 1 are applied to the same text description, and Let me repeat. This embodiment further defines Embodiment 1.

As shown in FIG. 2, before the step S1, the embodiment may include:

Step S03: Obtain the number of identifiers of the network device in the polling queue.

Step S04: Determine the preset value P according to the number of identifiers of the network device in the polling queue.

Specifically, if the number of the identifiers of the network devices in the polling queue is larger, the preset value P is smaller to ensure that all network devices in the polling queue are accessed once in a certain time interval.

More specifically, step S03 and step S04 may be set to be executed after the preset number of times is updated in the polling queue, or may be set to be executed after a preset time. When the calculation of the preset value P is performed for the first time, the preset value P is determined according to the number of identifiers of the network devices in the polling queue. When the preset value P already exists, the value of the preset value P may be corrected according to the number of the identifiers of the updated network device.

Thereby, the number of processing of the data packet can be adaptively increased or decreased, and the fair scheduling of the plurality of network devices is realized, and the real-time performance of the data processing is ensured.

It should be noted that, in this embodiment, the order of execution of step S03 and step S01 is not limited. What is shown in the drawings is only an implementation and is not a limitation of the order of execution.

Step S101: Acquire, according to the identifier of the network device in the polling queue, the communication traffic of each network device in the polling queue.

Step S102: Calculate a preset time according to the communication traffic of each network device in the polling queue;

In step S103, the identifier of the network device in the polling queue is obtained according to the preset time, and the number of data packets corresponding to the network device is obtained according to the identifier of the network device.

The calculation of the preset time can be achieved by setting a timer. The timer starts timing when there is data update in the polling queue. When the preset time is reached, the timer notifies the CPU to process the data packet. The timer is reset when the CPU starts data processing. The timer determines the time interval of the next polling by querying the status of the current network, and adjusts the frequency of the timer to achieve the purpose of adaptive network conditions. If the network is in a large amount of traffic and the data buffer update frequency is high, then the corresponding polling frequency is increased, that is, the timer interval is reduced, and the preset time is shortened. If the amount of data on the network is small, the polling frequency is reduced accordingly, and the time interval of the timer is increased to increase the preset time.

The step S1 may further include: determining whether the network device exists in the polling queue, and when there is an identifier of the network device in the polling queue, performing step S101, when the identifier of the network device does not exist in the polling queue. , receiving interrupts.

Therefore, the preset time is calculated according to the communication traffic of each network device in the polling queue, and the identifier of the network device in the polling queue is obtained according to the preset time, and is obtained according to the identifier of the network device. The number of data packets corresponding to the network device, according to network traffic Time is adjusted to improve the effectiveness of user process and kernel space data interaction.

Example 7

The network device is used as an example for the network card.

In the embodiment of the present invention, the processing method of the network device by the system may be changed when the first data packet arrives. The specific method is:

When the first packet arrives, the NIC generates a hardware interrupt and the system then enters interrupt processing. The system closes the receiving interrupt of the network card, registers the network card device into the polling queue, then wakes up the soft interrupt and enters the polling processing program.

The processor uses the polling mode to perform data reading on the network device in the polling queue. Before each reading, it is determined whether there is fixed quota data in the buffer of the network card, and if so, the data in the network card buffer is obtained. If the packet is not sufficiently fixed, the network device is logged out of the polling queue after all data has been read.

Then it is judged whether the polling queue is empty. If it is not empty, the polling start is returned, otherwise the soft interrupt processing ends, and then the receiving of the network card is interrupted.

Therefore, the present invention approaches the interrupt mode in the case of light load, and the response speed is fast; in the case of heavy load, it approaches the polling mode, efficiently processes the data packet and avoids the interruption in the case of heavy load. Live lock and packet loss issues.

The inventors of the present invention have noticed that the adjustable interrupt polling completes the effective reading of data from the network card to the kernel, and the user process reading data from the kernel is also an important part of improving the data reception of the high speed network. Adapted polling daemon technology, the specific approach is:

The upper application uses polling to monitor the status of the data buffer update. When the data buffer is updated, a timer is turned on and the application is temporarily hibernated. If the polling is not turned on within the time specified by the timer, the timer wakes up the upper application to process the data.

If the upper program has processed the data in the buffer, the timer will start timing again. In the timer interrupt processing function, the time interval of the next polling is determined by querying the current running state, and the frequency of the timer is adjusted to achieve the purpose of adaptive network conditions.

If the network is in a large amount of traffic and the data buffer update frequency is high, increase the polling frequency accordingly and decrease the timer interval. If the amount of data on the network is small, the polling frequency is reduced accordingly, and the time interval of the timer is increased.

During the polling process, if the system is connected to multiple network devices, setting the quota (preset value P) can effectively solve the fair scheduling problem of multiple network devices. However, if the quota is set to be large, when there are many network devices in the polling queue, the data packets of each network device cannot be processed in time, so that the real-time performance of the data cannot be guaranteed. Conversely, if the set quota is small and there are not many devices in the polling queue, it will cause frequent context switching, resulting in unnecessary overhead. The adjustable maximum quota technology can dynamically change the number of readable quotas according to the number of network devices in the polling queue, thus ensuring data real-time and system effectiveness.

In addition, the inventors of the present invention have also noticed that in the case of a multi-core multi-network device, when a continuous flow of data packets comes, if the CPU is not specifically limited, that is, each CPU can be used to process the network. Device data packets, so that multiple CPUs can be used simultaneously to process a large number of data packets sent from multiple network devices. Since the hard interrupt is closed before the NIC soft interrupt is executed, no interruption can interrupt such processing. The process until the soft interrupt ends itself. In extreme cases, because no processor can be used to process other processes, it can cause the system to crash. Accordingly, the present invention proposes to limit the processing of network device data packets by a particular CPU, thereby avoiding the collapse of the system in such extreme cases while ensuring efficient use of the processor.
