Abstract
Embodiments of the present disclosure provide a method, apparatus, device, and computer readable storage medium for processing a message. The method comprises the following steps: receiving a message to be processed; selecting a message processor corresponding to the message to be processed from a plurality of processors according to the received packet steering table; determining a receiving application corresponding to the message to be processed from a plurality of applications according to the message attribute of the message to be processed; if the processor where the receiving application is located is inconsistent with the message processor, confirming the priority of the receiving application; comparing the priority with a preset priority; if the priority is greater than the preset priority, updating the receiving packet steering table, otherwise, not updating the receiving packet steering table. In this way, if it is confirmed that some receiving applications have low priorities, the receiving packet steering table is not updated by the receiving applications having low priorities, which reduces the frequency of modification of the receiving packet steering table, and naturally reduces the number of entries in the receiving packet steering table that need to be modified, which improves the message processing performance.
Description
Technical Field
The present disclosure relates to the field of information processing, and in particular, to the field of message processing technology.
Background
Currently, in order to increase the processing power of devices, many devices are configured with multiple processors (CPUs, central processing unit), and different applications on such devices may run on different processors to achieve load balancing. At this time, after receiving the message sent by other devices, in order to implement efficient processing of the message, a sending processor corresponding to the message is selected first, and the sending processor is used as a message processor, so as to buffer the message by using the message processor, and further determine a receiving application corresponding to the message, so that the receiving application can acquire the message by means of the message processor, and the device with multiple processors can quickly transmit and process the message.
However, in practice, for various reasons, the selected message processor and the processor where the receiving Application is located may not be the same processor, and at this time, the processor where the receiving Application is located needs to buffer the message once again, so that the receiving Application can obtain the message, and the buffer times of the message are increased, which greatly affects the cache of the device, and affects the packet receiving performance, so that in order to improve the packet receiving performance, it is required to update the receiving packet steering table (such as the SOCK_RPS table item shown in FIG. 1, where RPS is RECEIVE PACKET STEERING, SOCK, i.e. Socket, socket), and update the message processor corresponding to the message in the receiving packet steering table to the processor where the receiving Application (APP, application) is located, as shown in FIG. 1, so as to ensure that the selected processor and the processor where the Application are located are the same as possible after receiving the similar message again, thereby fully utilizing the cache of the device to achieve the best optimization effect.
Thus, there are the following problems:
1. If the same message is concerned by different applications and the different applications run on different processors, frequent modification of the received packet steering table is required, as shown in fig. 2, and if APP1 (application 1) and APP2 (application 2) are both concerned with the message and APP1 and APP2 find that the processor where they are located is inconsistent with the message processor selected by the table entry, then the received packet steering table needs to be modified for 2 times, and at this time, the message processing performance will not be improved or even deteriorated.
2. When the application is particularly numerous, the entries in the received packet steering table that need to be modified will be numerous and will also affect the message processing performance.

Fig. 3 illustrates a flow chart of a message processing method 300 according to an embodiment of the disclosure. The method 300 is applicable to an operating system of various terminals such as vehicles having a plurality of processors, and may include:
step 310, receiving a message to be processed, wherein the message comprises a message attribute;
the message to be processed may come from other devices.
Step 320, selecting a message processor corresponding to the message to be processed from a plurality of processors according to a received packet steering table;
The receiving packet steering table is a table, and specific forms include, but are not limited to, EXCEL and the like, and the corresponding relation between the packet and the processor recorded in the receiving packet steering table is used for selecting a packet processor, specifically, the corresponding relation between the type of the packet and the identifier of the processor can be recorded in the receiving packet steering table, so that the corresponding packet processor can be determined after the receiving packet steering table is queried according to the type of the to-be-processed packet, wherein the type of the packet includes, but is not limited to, a packet attribute or a hash value calculated based on the packet attribute.
For example: the received packet forwarding table may store a correspondence between a hash value (hash) of the packet and an identifier (such as a number, a model, a name, or a combination thereof) of the processor, where the calculation of the hash value may be calculated by a quadruple (source IP, source port number, destination IP, destination port number), where IP is Internet Protocol Address is an internet protocol address.
Preferably, if there is a received packet forwarding table and the type of the message to be processed can be queried from the received packet forwarding table, it is determined which processor should be used as a message processor to process (buffer, forward) the message to be processed according to the received packet forwarding table and the type of the message to be processed.
If there is no received packet steering table or there is a received packet steering table but the type of the message to be processed cannot be queried from the received packet steering table, a certain processor is randomly selected from a plurality of processors as a message processor to process (buffer and forward) the message to be processed, and then the received packet steering table is created or updated according to the identification of the randomly selected processor and the type of the message to be processed.
Step 330, reading the message attribute from the message to be processed;
Step 340, determining a receiving application corresponding to the message to be processed from a plurality of applications according to the message attribute of the message to be processed;
Step 350, if the processor where the receiving application is located is inconsistent with the message processor, confirming the priority of the receiving application;
A receiving application refers to an application that is ultimately to receive and respond to a message,
On which processor the receiving application is running, the processor being the processor on which the receiving application is located.
The processor where the receiving application is located is inconsistent with the message processor means that the processor where the receiving application is located is not the same processor as the message processor.
Step 360, comparing the priority with a preset priority;
The priority of each application is preset, and can be determined by the receiving application according to the importance degree of the service processed by each application and fed back to the operating system; in addition, the priority of each application may be stored in any file in the priority table. For example: the priority levels of (1) can be classified into 5 priorities of L1, L2, L3, L4, and L5, wherein the priorities of L1, L2, L3, L4, and L5 are sequentially increased.
The preset priority includes: an application priority threshold or the priority of the application which receives the message with the same type as the message to be processed last time;
The application priority threshold is a global priority, and does not change due to a change in the priority of an application, and if used, the application priority must be greater than the application priority threshold in order to update the received packet steering table according to the priority of an application.
The application priority threshold may be based on the priority of each application, and may be averaged, e.g., the application priority threshold may be L3.
The priority of the application that receives the message with the same type as the message to be processed, that is, the priority of the application that receives the message with the same type last time, where the type of the message to be processed may depend on the message attribute (the message attribute includes but is not limited to IP address port number, protocol type, service type of the message, etc.), or since the message attribute can determine that the application is received, it is already very detailed, and thus, may depend on some attributes in the message attribute (such as four elements of source IP, source port number, destination IP, destination port number, or three elements of source IP, source port number, destination IP).
And 370, if the priority is greater than the preset priority, updating a received packet steering table, otherwise, not updating the received packet steering table, wherein the received packet steering table stores a correspondence between messages and processors and is used for selecting the message processor.
After receiving a message to be processed, a message processor can be selected from a plurality of processors according to a received packet steering table, then the message attribute is read from the message to be processed, further, according to the message attribute of the message to be processed, a receiving application corresponding to the message to be processed is determined from a plurality of applications, further, whether the processor where the receiving application is located is consistent with the message processor is confirmed, if not, the priority of the receiving application is confirmed, then the priority of the application is compared with the preset priority, if the priority of the receiving application is greater than the preset priority, the received packet steering table is updated, otherwise, the received packet steering table is not updated, if the priority of some receiving applications is confirmed to be low, the received packet steering table is not updated due to the receiving application with low priority, and only the received packet steering table is updated due to the receiving application with high priority, so that the modifying frequency of the received packet steering table is reduced, and the number of the tables needing to be modified in the received packet steering table is naturally reduced, so that the message processing performance is improved.
The received packet steering table stores exactly the correspondence between the hash value (hash) of the packet and the identity of the processor, and the calculation of this hash value can be calculated by a quadruple (source IP, source port number, destination IP, destination port number), where IP is Internet Protocol Address, which is an internet protocol address.
After updating the receiving packet steering table, as long as the received new message is the same as the quadruple of the to-be-processed message, the new message is considered to be a similar (same type) message of the to-be-processed message, and the receiving packet steering table can be utilized to correctly confirm the message processor corresponding to the message, so that the message processor is ensured to be identical with the processor of the receiving application corresponding to the new message as far as possible, secondary buffering of the message is avoided, high-speed buffering of equipment is fully utilized, and the message processing efficiency is improved. .
In some embodiments, after selecting a message processor corresponding to the message to be processed, the method further includes:
adding an identifier of the message processor in the message to be processed; the identification includes, but is not limited to, a name, a label, etc.
Determining, by the receiving application, an identity of a processor in which it is located;
Because each application will take various data from its processor, each application can determine exactly which processor it is on during the process of reading the data.
If the processor where the receiving application is located is inconsistent with the message processor, confirming the priority of the receiving application, including:
and if the identification of the processor where the receiving application is located is inconsistent with the identification of the message processor added in the message to be processed, confirming the priority of the receiving application.
After confirming the message processor, the identification of the message processor can be added to the message to be processed, the message processor is utilized to buffer the message, meanwhile, the receiving application is informed to read the message from the buffer memory of the processor where the receiving application is located, after receiving the notification, the receiving application can confirm whether the identification of the processor where the receiving application is located is consistent with the identification of the message processor added to the message to be processed or not from the read message, if not, the priority of the receiving application needs to be confirmed, and whether the receiving packet steering table is updated or not is conveniently judged by utilizing priority comparison.
Of course, if they are inconsistent, it means that the processor where the receiving application is located reads the message from the buffer of the message processor once again and buffers the message once again.
In some embodiments, the preset priority comprises: an application priority threshold or the priority of the application which receives the message with the same type as the message to be processed last time;
And if the priority is greater than the preset priority, updating a received packet steering table, including:
if the priority is greater than the application priority threshold, updating the received packet steering table; or alternatively
And if the priority is greater than the priority of the application which receives the message with the same type as the message to be processed last time, updating the received packet steering table.
The application priority threshold is a global priority, and does not change due to a change in the priority of an application, and if used, the application priority must be greater than the application priority threshold in order to update the received packet steering table according to the priority of an application.
The application priority threshold may be based on the priority of each application, and may be averaged, e.g., the application priority threshold may be L3.
And the priority of the application which receives the message with the same type as the message to be processed last time, namely the priority of the application which receives the message with the same type last time, wherein the type of the message to be processed can be determined according to the message attribute or part of the attribute in the message attribute.
Specifically, the priority of the application that receives the message with the same type as the message to be processed last time refers to the priority of the application that processes the message when the message with the same type is received last time. If the priority of the receiving application is greater than the application priority threshold or the priority of the receiving application is greater than the priority of the application which receives the message of the same type as the message to be processed last time, the priority of the receiving application is high, so that the receiving packet steering table can be updated according to the receiving application, the receiving packet steering table is prevented from being modified due to the application with low priority, the modification frequency of the receiving packet steering table is reduced, the number of items to be modified in the receiving packet steering table is naturally reduced, and the message processing performance is improved.
In some embodiments, the preset priority comprises: an application priority threshold and the priority of the application which receives the message with the same type as the message to be processed last time;
And if the priority is greater than the preset priority, updating a received packet steering table, including:
If the priority is greater than the application priority threshold, comparing the priority with the priority of the application which receives the message with the same type as the message to be processed last time;
And if the priority is greater than the priority of the application which receives the message with the same type as the message to be processed last time, updating a receiving packet steering table.
If the priority of the receiving application is greater than the application priority threshold, the priority of the receiving application can be further compared with the priority of the application which receives the message with the same type as the message to be processed last time, if the priority of the receiving application is greater than the priority of the application which receives the message with the same type as the message to be processed last time, the priority of the receiving application can be fully described as being very high, so that the receiving packet steering table can be updated according to the receiving application, the receiving packet steering table is prevented from being modified due to the application with low priority, the modification frequency of the receiving packet steering table is reduced, the number of table items to be modified in the receiving packet steering table is naturally reduced, and the message processing performance is improved.
In some embodiments, the updating the received packet steering table includes:
And updating the message processor corresponding to the message to be processed, which is recorded in the received packet steering table, into a processor where the receiving application is located. The identification of the message processor corresponding to the type of the message to be processed recorded in the received packet steering table is updated to the identification of the processor where the receiving application is located, so that the processor where the receiving application is located can be used as the message processor when the message of the same type is received next time, and the buffer hit rate of the processor is improved.
The process of updating the receiving packet steering table is to update the message processor corresponding to the message to be processed recorded in the receiving packet steering table to the processor where the receiving application is located, so that the message processor corresponding to the message to be processed recorded in the receiving packet steering table can be updated due to the application with high priority, and correct message processor can be selected after receiving the similar (same type) message again, thereby improving the buffer hit rate of the processor, and further improving the message processing efficiency and the message processing performance.
Of course, if the message processor corresponding to the message to be processed is not recorded in the received packet steering table, determining the processor where the receiving application is located as the message processor corresponding to the message to be processed, and recording the determined message processor in the received packet steering table.
In some embodiments, the received packet steering table comprises a first received packet steering table and a second received packet steering table, wherein a query level of the first received packet steering table is higher than a query level of the second received packet steering table;
The query level refers to a query priority order, the query level of the first received packet steering table is higher than the query level of the second received packet steering table, the first received packet steering table is queried preferentially, and after which processor is not used as a message processor in the first received packet steering table, the second received packet steering table is queried again.
The updating the message processor corresponding to the message to be processed recorded in the received packet steering table to the processor where the receiving application is located includes:
Updating the message processor corresponding to the message to be processed recorded in the first receiving packet steering table to be the processor where the receiving application is located, wherein the corresponding relation between the message stored in the second receiving packet steering table and the processor is different from the corresponding relation between the message stored in the first receiving packet steering table and the processor, and the second receiving packet steering table cannot be updated according to the priority.
The first received packet steering table is queried at a higher level than the second received packet steering table, and thus the first received packet steering table is updated when the received packet steering table is updated.
The first receiving packet steering table is a SOCK_RPS table item, wherein SOCK is Socket and Socket;
The second received packet steering table is an RPS table entry;
The corresponding relation between the second receiving packet steering table and the processor is preset, and is automatically generated according to some principles, for example, the corresponding relation between the second receiving packet steering table and the processor is different from the corresponding relation between the first receiving packet steering table and the processor, specifically, when a certain type of message is received for the first time, the processor required by processing the type of message is generated, and after the same type of message is received again, if the processor corresponding to the type of message is updated, the processor corresponding to the first receiving packet steering table is required to be updated, and the second receiving packet steering table is not updated, so that the corresponding relation between the second receiving packet steering table and the message stored in the first receiving packet steering table is different from the corresponding relation between the first receiving packet steering table and the processor, and the corresponding relation between the second receiving packet steering table and the processor is generated when the number of the second receiving packet steering table is different from the first receiving packet steering table is higher than the first receiving packet steering table, the corresponding relation between the number of the second receiving packet steering table and the first receiving packet is higher than the first receiving packet steering table is generated, and the corresponding relation between the second receiving packet steering table and the first receiving packet is deleted.
In addition, the priority of the application that receives the message of the same type as the message to be processed last time may be recorded in the first received packet steering table, or other positions, but is not suitable for recording in the second received packet steering table, because the query level of the second received packet steering table is low, and is not suitable for recording.
The corresponding relation between the message and the processor recorded in the first receiving packet steering table is the corresponding relation which is modified according to the processor where the receiving application is located when the processor where the receiving application is located is inconsistent with the message processor, and the accuracy is high, and the selected processor and the processor where the receiving application is located can be ensured to be identical, so that the query level of the first receiving packet steering table is higher than the query level of the second receiving packet steering table.
In some embodiments, the selecting, from a plurality of processors according to a received packet steering table, a message processor corresponding to the message to be processed includes:
Selecting the message processor from the plurality of processors according to the first received packet steering table and the message to be processed;
When selecting, the message processor corresponding to the type of the message to be processed can be automatically selected from a plurality of processors according to the type of the message to be processed, the type of the message recorded in the first receiving packet steering table and the identification of the processor.
If the message processor is not queried from the first receiving packet steering table, selecting the message processor from the plurality of processors according to the second receiving packet steering table and the message to be processed;
The principle of selecting the message processor in the second received packet steering table is the same as that described above, and will not be repeated here.
And if the message processor is not queried from the second received packet steering table, randomly selecting the message processor from the plurality of processors.
Because the priority of the first receiving packet steering table is higher than that of the second receiving packet steering table, that is, the processor corresponding to the message recorded in the first receiving packet steering table is more accurate than the processor corresponding to the message recorded in the second receiving packet steering table, the message processor can be selected from the plurality of processors preferentially according to the first receiving packet steering table and the message to be processed, then if the message processor is not queried from the first receiving packet steering table, the message processor is selected from the plurality of processors according to the second receiving packet steering table and the message to be processed, and if the message processor is not queried in the second receiving packet steering table, the message processor can be selected from the plurality of processors randomly.
Of course, if the first receiving packet steering table and the second receiving packet steering table exist, only the processor corresponding to the message to be processed is not found from the first receiving packet steering table and the second receiving packet steering table, and when a certain processor is randomly selected as the message processor, the first receiving packet steering table needs to be updated according to the randomly selected message processor and the message to be processed;
It should be noted that, there is a very special case, if there is no first receiving packet steering table and no second receiving packet steering table, after receiving the message to be processed, it is also necessary to randomly select a message processor from a plurality of processors, and then create the second receiving packet steering table according to the randomly selected message processor and the message to be processed, which is not the focus of the present disclosure.
In some embodiments, the determining, according to the message attribute of the to-be-processed message, the receiving application of the to-be-processed message from multiple applications includes:
acquiring message attributes corresponding to a plurality of pre-recorded applications respectively;
Message attributes of the message to be received include, but are not limited to, IP address, port number, protocol type, service type, etc. of the message to be processed.
The message attributes corresponding to the applications respectively, namely the attributes of the messages concerned by the applications respectively, wherein the message attributes include but are not limited to: IP address, port number, protocol type, traffic type of the message, etc.
And selecting the receiving application from the plurality of applications according to the message attribute and the message attribute corresponding to each of the plurality of applications.
By automatically matching the message attribute with the message attribute corresponding to each of the plurality of pre-recorded applications, the receiving application can be automatically selected from the plurality of applications, so that the accuracy of selecting the receiving application is improved.
The technical solution of the present disclosure will be described in further detail below with reference to fig. 4 and 5:
As shown in fig. 4, the network card selects the CPU by querying the sock_rps table entry, if no sock_rps table entry continues to query the RPS table entry, no RPS table entry is selected from the multiple CPUs at random for uploading, the uploading CPU caches the message, then puts the message into the APP message queue, and at the same time, the operating system confirms the received APP corresponding to the message (assuming that the received APP includes APP1 and APP 2), and notifies the received APP, and of course, no table entry exists in the initialized state.
Receiving an APP notification, receiving a message, confirming whether the CPU is consistent with the CPU where the APP is located according to the identification of the uploading CPU carried in the message, if the CPU is inconsistent with the CPU, comparing the priority of the APP with an application priority threshold (shown in figure 5) by the APP1 and the APP2 in the received APP, and if the priority of the APP1 is higher than the application priority threshold and the priority of the APP2 is lower than the application priority threshold, feeding back to an operating system by the APP1 to update the selected CPU corresponding to the message in the SOCK_RPS table item to the priority where the APP1 is located, and if the priority of the APP2 is low, not feeding back by the APP2, so that the SOCK_RPS table item is not updated by the APP 2.
The flow of fig. 6 and 7 is similar to that of fig. 4 and 5, except that the priority comparison process compares the application priority with the application priority threshold, and also compares the application priority with the priority of the application that received the same message as the message to be processed last time, so as to ensure that only the application with a sufficiently high priority affects the dock_rps table entry and avoid too frequent modification of the dock_rps table entry to affect the message processing performance.
