It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
At present, network devices usually discard packets reaching a network port randomly when network congestion occurs, so as to alleviate the network congestion. However, this will cause random packet loss of the network service carried by the network device, which will affect the normal use of the network service. In some embodiments of the present application: whether network congestion occurs in the network equipment can be determined by detecting the amount of available cache resources in a cache queue of the network equipment; when network congestion occurs, a suspended message processing flow line and a normal message processing flow line can be determined from each message processing flow line according to the importance degree of the service carried by each message processing flow line; and can suspend receiving the message of the current bearing service of the suspended message processing pipeline. Therefore, the message of part of the service can be selectively received into the buffer queue according to the service importance degree, the packet loss rate of the important service is favorably reduced, and the service quality of the important service is effectively improved.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic flow chart of a flow control method according to an embodiment of the present application. As shown in fig. 1, the method includes:
100. detecting the amount of available cache resources in a cache queue of the network equipment;
101. when detecting that the amount of available cache resources is smaller than a preset lower limit value, determining a suspended message processing pipeline and a normal message processing pipeline from all message processing pipelines according to the importance degree of the current bearing service of all message processing pipelines sharing a cache queue;
102. and suspending receiving of the message of the current bearing service of the suspended message processing pipeline so as to ensure that the message of the current bearing service of the normal message processing pipeline is successfully received into the cache queue when arriving.
In this embodiment, the network device may be a data switching node device such as a switch, a router, or a gateway, and certainly may also be other devices capable of bearing network services, which is not limited in this embodiment. Accordingly, the flow control method provided by this embodiment can be applied to various types of network devices to improve the quality of service of important services carried by the network devices.
In this embodiment, the network device may use a message processing pipeline to carry various services. In the process of initializing the network equipment, the number of message processing pipelines supported by the network equipment can be set according to parameters such as the number of processor cores of the network equipment, the total bandwidth of a communication interface and the like. One message processing pipeline can bear one service and can continue to process other services after one service is processed, that is, the service borne by the same message processing pipeline is dynamically changed. Therefore, in this embodiment, the network device can simultaneously carry multiple services based on multiple packet processing pipelines.
The message processing pipelines can share a buffer queue, and the buffer queue is used for storing messages to be processed. In this embodiment, whether the network device enters the network congestion state may be determined by detecting the amount of available cache resources in the cache queue of the network device. For example, it may be determined that the network device enters a network congestion state when it is detected that the amount of available cache resources is less than a preset lower limit. In some practical applications, a cache resource query request may be sent to a hardware monitoring component of a network device; and receiving a query result returned by the hardware monitoring component according to the cache resource query request, wherein the query result comprises the available cache resource amount of the cache queue. Of course, the amount of the cache resource available in the cache queue of the network device may also be obtained in other manners or from other ways, and the embodiment is not limited thereto.
In this embodiment, the amount of available buffer resources in the buffer queue of the network device may be detected at intervals, and the interval time may be set according to an actual situation. For example, the interval time may be set according to the total bandwidth of the communication interface of the network device, the core count of the processor, and the total number of buffers in the buffer queue. Of course, the interval time may also be determined according to other performance indicators of the network device, which is not limited in this embodiment.
In addition, the preset lower limit value adopted when judging whether the network equipment enters the network congestion state can be set according to the actual situation. For example, the appropriate lower limit value may be set according to the total bandwidth of the communication interface of the network device and the total amount of buffers in the buffer queue. Of course, the lower limit value may also be determined according to other performance indicators of the network device, which is not limited in this embodiment.
When the network equipment is determined to enter the network congestion state, a suspended message processing flow line and a normal message processing flow line can be determined from all the message processing flow lines according to the importance degree of the current bearing service of all the message processing flow lines sharing the cache queue. Based on the foregoing description of the packet processing pipeline in the network device, in this embodiment, different packet processing pipelines in the network device carry different services, and the importance degrees of the different services may not be completely the same. In order to preferentially ensure the service quality of important services, in some practical applications, a message processing pipeline carrying a service with a lower importance degree in each message processing pipeline can be determined as a suspended message processing pipeline, and a message processing pipeline carrying a service with a higher importance degree can be determined as a normal message processing pipeline. For example, when there are 5 message processing pipelines in the network device, the message processing pipelines may be sorted according to the importance of the service carried by each message processing pipeline, 2 message processing pipelines with lower importance are determined as suspended message processing pipelines, and the other 3 message processing pipelines are determined as normal message processing pipelines.
Based on the determined pause message processing flow line and the normal message processing flow line, when a message reaches a communication interface of the network device, the message processing flow line corresponding to the message can be determined according to the service corresponding to the message, when the message processing flow line corresponding to the message is the pause message processing flow line, the message is discarded, and when the message processing flow line corresponding to the message is the normal message processing flow line, the message can be normally received to the cache queue. Accordingly, in this embodiment, the processing of the service carried by the suspended message processing pipeline can be suspended by suspending receiving the message of the service carried by the suspended message processing pipeline, so as to centralize the available resources of the network device on the processing of the service carried by the normal message processing pipeline. In the above example, when the packet is a packet of a service carried by 2 suspended packet processing pipelines, the packet is discarded, so that no more packet of a service carried by 2 suspended packet processing pipelines is added to the buffer queue, and accordingly, the 2 suspended packet processing pipelines are suspended.
In this embodiment, whether network congestion occurs in the network device may be determined by detecting the amount of available cache resources in the cache queue of the network device; when network congestion occurs, a suspended message processing flow line and a normal message processing flow line can be determined from each message processing flow line according to the importance degree of the service carried by each message processing flow line; and can suspend receiving the message of the current bearing service of the suspended message processing pipeline. Therefore, the message of part of the service can be selectively received into the buffer queue according to the service importance degree, the packet loss rate of the important service is favorably reduced, and the service quality of the important service is effectively improved.
In the above or the following embodiments, after suspending receiving the message of the current bearer service of the suspended message processing pipeline, the amount of available buffer resources in the buffer queue will dynamically change along with the continuous operation of each normal message processing pipeline. Therefore, after the message of the current bearing service of the pause message processing assembly line is paused to be received, the available buffer resource amount in the buffer queue can be continuously detected; and when the available cache resource amount is continuously detected to be still less than the preset lower limit value, determining a message processing pipeline changed into a suspended message processing pipeline from the normal message processing pipeline according to the importance degree of the current bearer service of the normal message processing pipeline, and suspending receiving the message of the current bearer service of the message processing pipeline changed into the suspended message processing pipeline.
If the available buffer resource amount is still smaller than the preset lower limit value, it indicates that the buffer resource amount occupied by the normal message processing pipeline is still large, and the network device is still in a network congestion state. In this case, the message processing pipeline with the lower importance of the service to be carried can be selected from the normal message processing pipelines and changed into the suspended message processing pipeline. The foregoing example is carried over, if the network device is still in a network congestion state after performing service processing according to the configuration of 2 suspended message processing pipelines and 3 normal message processing pipelines in the network device, 1 message processing pipeline can be selected from the 3 normal message processing pipelines to be changed into a suspended message processing pipeline, and accordingly, the network device will include the 3 suspended message processing pipelines and the 2 normal message processing pipelines.
By reducing the number of normal message processing pipelines, the network congestion state of the network device can be further alleviated. Certainly, the operation of detecting the amount of available buffer resources in the buffer queue of the network device is an intermittent and continuous operation, after the proportion configuration of the pause class and the normal class in each message processing pipeline in the network device is adjusted, the adjustment effect can be determined by detecting the amount of available buffer resources in the buffer queue of the network device, and when the network congestion state of the network device still cannot be changed, the number of normal message processing pipelines can be continuously reduced until the network congestion state of the network device is changed. In practical application, the network congestion state of the network device can be effectively changed only by determining a smaller number of message processing pipelines as message processing pipelines to be suspended, so that the service quality of most important services can be ensured.
As described above, by reducing the number of normal message processing pipelines in the network device, the network congestion state of the network device can be improved, which is mainly because the number of messages received in the cache queue is reduced as the number of normal message processing pipelines is reduced, and the amount of available cache resources in the cache queue is increased as the messages to be processed in the cache queue are continuously processed. Therefore, in this embodiment, when it is detected that the amount of the available cache resources is greater than or equal to the preset upper limit, according to the importance degree of the current bearer service of the suspended message processing pipeline, a message processing pipeline which is restored to the normal message processing pipeline is determined from the suspended message processing pipeline, and the message of the current bearer service of the message processing pipeline which is restored to the normal message processing pipeline is normally received into the cache queue when the message arrives. Wherein the preset upper limit value may be greater than or equal to the preset lower limit value mentioned above.
When the amount of the available cache resources is detected to be larger than or equal to the preset upper limit value, it is indicated that the network equipment has entered a network unobstructed state, and at this time, the network equipment can carry more services. Therefore, one or more message processing pipelines can be selected from the suspended message processing pipelines to be recovered to be the normal message processing pipelines, namely, the proportion of the normal message processing pipelines in the network equipment is increased so as to process more services. Certainly, after the proportion of the normal message processing pipeline in the network device is increased, the available amount of the cache resources in the cache queue of the network device may be continuously detected, when it is detected that the available amount of the cache resources is still greater than or equal to the preset upper limit value, the proportion of the normal message processing pipeline may be continuously increased, and when it is detected that the available amount of the cache resources is less than the preset lower limit value, the proportion of the normal message processing pipeline needs to be decreased.
Accordingly, in this embodiment, the proportion of the normal packet processing pipeline in the network device can be adaptively adjusted according to the dynamic change of the amount of the available buffer resources in the buffer queue of the network device, so that the network device can operate in a relatively stable network state, and the service quality of services as much as possible can be improved.
In the foregoing or following embodiments, the priority of each packet processing pipeline may be determined according to the type of the current service carried by each packet processing pipeline, where the type of the service may represent the importance of the service; and selecting at least one message processing pipeline with the lowest priority as a suspended message processing pipeline according to the priority of each message processing pipeline.
In this embodiment, when the message processing pipeline is determined to be suspended, the priority of each message processing pipeline may be defined according to the type of the service carried by each message processing pipeline. As described above, the bearer service of the message processing pipeline is dynamically changed, so that the current bearer service type of each message processing pipeline can be monitored in real time, and the priority of each message processing pipeline can be dynamically adjusted when the current bearer service type of each message processing pipeline changes. In this way, the priority of each message processing pipeline in the network device may change dynamically with the change of the bearer service. Furthermore, as the priority of the message processing pipeline dynamically changes, the processing state of the message processing pipeline may also dynamically change. For example, when the priority of a message processing pipeline is low, it is determined to be a suspended-type message processing pipeline, and when the priority of the message processing pipeline is raised due to a change in traffic carried by the message processing pipeline, the message processing pipeline is adjusted to be a normal message processing pipeline. The method can ensure the conformity between the configuration of the processing state of each message processing pipeline in the network equipment and the bearing service of each message processing pipeline, and avoid neglecting to process important services.
The types of the services include, but are not limited to, Enterprise Resource Planning (ERP), database, Office Automation (OA), website video, online games, and the like. The type of business may characterize the importance of the business, e.g., ERP is typically more important than online gaming. In some practical applications, the corresponding relationship between the type of the service and the priority can be established in advance, and accordingly, the priority of each message processing pipeline can be determined according to the type of the service carried by each message processing pipeline. For example, if the priority is determined to be in the range of 0 to 2, the types of the services can be sorted according to the importance degree and associated with an appropriate priority value.
Therefore, when the processing state of each message processing pipeline in the network equipment is configured, each message processing pipeline in the network equipment can be sequenced according to the priority, at least one message processing pipeline with the lowest priority is used as a pause message processing pipeline, and other message processing pipelines are used as normal message processing pipelines. In this way, traffic of relatively low importance can be suspended, with priority to ensure that important traffic is processed normally.
In this embodiment, the force for adjusting the ratio of the normal message processing pipeline to the suspended message processing pipeline in the network device may be set as a message processing pipeline in combination with the operation of detecting the amount of available buffer resources in the buffer queue of the network device. When the network equipment is in a network congestion state, one message processing assembly line with the lowest priority level can be selected from the normal message processing assembly lines each time and changed into a pause message processing assembly line, the available buffer resource amount in the buffer queue of the network equipment is continuously detected, and if the network equipment is still in the network congestion state, the rest message processing assembly line with the lowest priority level is selected from the normal message processing assembly lines and changed into the pause message processing assembly line until the network equipment is separated from the network congestion state. And when the network equipment enters a network unobstructed state, selecting one message processing assembly line with the highest priority from the pause message processing assembly lines each time to recover to be a normal message processing assembly line, and continuously detecting the available buffer resource amount in the buffer queue of the network equipment, if the network equipment is still in the network unobstructed state, continuously selecting one message processing assembly line with the highest priority from the pause message processing assembly lines to recover to be the normal message processing assembly line until the network equipment is found to leave the network unobstructed state.
In practical applications, a network stable state between a network congestion state and a network smooth state is defined for the network device by setting the preset upper limit value mentioned in the foregoing embodiments to be greater than the preset lower limit value, and the network stable state is used as an adjustment target, and the network device is maintained in the network stable state by adjusting the ratio of a normal message processing pipeline to a pause message processing pipeline in the network device, so as to ensure the quality of service of an important service.
Fig. 2 is a schematic diagram of a working architecture in which a multi-core network device bears multiple services according to an embodiment of the present application. As shown in fig. 2, the network device includes three message processing pipelines, which can respectively carry different services, and each message processing pipeline can be divided into three modules, taking a message forwarding task for processing various services as an example: the system comprises a drive receiving module, a processing and forwarding module and a drive sending module, wherein the three modules respectively correspond to three stages of a message forwarding task, namely: a message receiving stage, a message processing stage and a message sending stage. In fig. 2, the network device includes a plurality of core processors, and processing jobs corresponding to respective modules on three message processing pipelines can be scheduled to appropriate core processors by the scheduling module for execution, where the scheduling module can be deployed in other core processors besides the core processors for executing processing jobs on the respective message processing pipelines. In this way, each module in a message processing pipeline may be executed by a different core processor. It should be noted that the number of packet processing pipelines, the number of modules included in the packet processing pipeline, contents, and the like in fig. 2 are all exemplary and should not limit the scope of the present application.
Accordingly, in the above or following embodiments, the message to be processed may also be read from the buffer queue, and the message to be processed is sequentially sent to the driving receiving module, the processing forwarding module, and the driving sending module on the message processing pipeline where the service corresponding to the message to be processed is located to perform message processing pipeline processing; and after the message processing pipeline processing of the message to be processed is finished, deleting the message to be processed from the cache queue to release cache resources.
In this embodiment, for the messages to be processed in the cache queue, the messages to be processed may be sequentially sent to the subsequent processing stages according to the processing stages included in the message processing pipeline. For example, for the message forwarding requirements of various services, the message processing pipeline may include a driving receiving module, a processing forwarding module, and a driving sending module. For a network device with a multi-core processor, the processing tasks of the modules can be scheduled to different core processors for processing, so that a plurality of message processing pipelines can run in parallel, and the network device can process a plurality of services in parallel.
After the message processing pipeline processing of the message to be processed is completed, the message to be processed can be deleted from the cache queue, the cache resource occupied by the message to be processed is released into an available cache resource, and accordingly, the amount of the available cache resource in the cache queue of the network device changes.
In this embodiment, the processing progress of the to-be-processed packet in the cache queue will bring dynamic changes of the amount of available cache resources in the cache queue, and based on the dynamic changes of the amount of available cache resources in the cache queue, the ratio between a normal packet processing pipeline and a suspended packet processing pipeline in the network device can be dynamically adjusted, and the network device is already maintained in a network stable state, so that the packet loss rate of the important service is reduced, and the service quality of the important service is improved.
