In the prior art, in order to improve the processing capability of the operating system on network data, the performance of the operating system may be improved in the Linux operating system through solutions such as net map, DPDK (Data Plane Development Kit ) and the like. In the net map, more kernel patches are injected into a network card driver and kernels in an operating system, so that a buffer area of the network card is mapped to an application state, and the application state processes message data in a network. In DPDK, the whole network card driver is directly implemented in an application state, and then a CPU (Central Processing Unit, abbreviated as CPU) is adopted to poll the network card, so as to implement processing of message data.
Because the net map and the DPDK change the kernel of the Linux operating system greatly, a large number of patches need to be added to realize the data forwarding of the message in the application state. When forwarding the message data in the application state, the existing protocol stack in the operating system cannot be utilized to directly forward, and the protocol stack needs to be reconstructed in the application state to forward, so that in the forwarding flow of the message data, the time for constructing the protocol stack is also needed, the message forwarding time is longer, and although the service performance of the application state in the operating system can be improved, the forwarding performance of the message data in the operating system is poorer.

Referring to fig. 2, fig. 2 is a flow chart of a message processing method according to an embodiment of the present application, where the method may include the following steps:
step S200, setting identification information in a cache structure body of the target message.
The identification information comprises a first identification and a second identification, wherein the first identification is used for marking whether the target message is sent completely or not, and the second identification is used for marking whether the target message is forwarded quickly or not. The target message is any message data which needs to be forwarded in the network environment of the operating system. The buffer structure is a structure in a receiving buffer area of the kernel mode of the operating system when receiving the message, namely a SKB (structure sk_buff, socket buffer) structure, and the buffer structure weight comprises all relevant data required by processing the network message data.
Step S210, adjusting the identification information in the target message based on the processing rule of the protocol stack to obtain adjustment identification information.
The method comprises the steps of setting an existing protocol stack in a kernel mode of an operating system, detecting the forwarding state of a target message according to processing rules in the existing protocol stack, and adjusting the numerical value marked in the set identification information in a cache structure according to the forwarding state of the target message when the target message is forwarded currently, so as to obtain adjustment identification information, and correspondingly changing according to the forwarding state of the target message.
Step S220, determining a target cache structure when the target message is sent and target identification information in the target cache structure according to the cache structure and the adjustment identification information.
After the target message is received, the forwarding state of the target message when the target message is transmitted after being received can be acquired through the buffer structure body and the adjustment identification information therein, and the target buffer structure body used when the target message is transmitted and the corresponding target identification information therein are determined on the basis of the forwarding state.
Step S230, determining whether the target cache structure is multiplexed based on the target identification information.
The method comprises the steps of judging a forwarding state of a target message when the target message is transmitted according to target identification information when the target message is transmitted, acquiring whether the target message is forwarded in a fast forwarding mode or not and whether the target message is transmitted completely or not, judging whether a target cache structure body can be reused according to the acquired situation, rapidly multiplexing the target cache structure body capable of being reused, recovering the target cache structure body incapable of being reused, and distributing the target cache structure body again by an operating system.
Optionally, a plurality of target messages to be forwarded can be processed at the same time, so as to judge whether the corresponding target cache structure can be reused, and efficiency in message processing is effectively improved.
In the embodiment shown in fig. 2, by setting the identification information indicating the forwarding state of the message data in the buffer structure body of the message data, the buffer area of the message data can be reused, so that the memory pressure of the buffer area during forwarding is reduced, and the forwarding performance of the system during forwarding the message data is improved.
Optionally, referring to fig. 3, fig. 3 is a detailed flowchart of step S200 provided in the embodiment of the present application, and step S200 may further include steps S201-S202.
Step S201, adding the first identifier and the second identifier in the cache structure body of the target packet.
The first identifier and the second identifier may be variable values capable of being changed, the first identifier may be denoted as tx_done, the second identifier may be denoted as tx_fast, and whether the target message is sent completely or not and whether the target message is forwarded in a fast forwarding manner are indicated by the change of the variable values.
For example, when the first identifier tx_done=0, it indicates that the target message is not sent, and when tx_done=1, it indicates that the target message is sent; when tx_fast=0, it indicates that the target packet is not forwarded in a fast forwarding manner, and when tx_fast=1, it indicates that the target packet is forwarded in a fast forwarding manner, where default values of the first and second identifiers may be set to 0, and non-default values are set to 1.
Optionally, when adding, the first identifier and the second identifier may be added to the buffer structure body first, and then the buffer structure body is allocated to the corresponding target message, or after the target message is obtained, the first identifier and the second identifier may be added to the buffer structure body corresponding to the target message.
Step S202, setting the values of the first identifier and the second identifier in the cache structure body to default values.
When the network card of the operating system is initialized, the first identifier and the second identifier in the buffer structure body received by each queue in the receiving interface of the network card can be initialized, the variable values of the first identifier and the second identifier are set to be default values, and the default values are 0, namely, the default values respectively indicate that the target message is not sent completely, and the target message is not forwarded in a fast forwarding mode.
In the embodiment shown in fig. 3, the target packet cache structure to be forwarded can be initialized to perform subsequent processing operations based on the initialized tag information.
Optionally, referring to fig. 4, fig. 4 is a detailed flowchart of step S210 provided in the embodiment of the present application, and step S210 may further include steps S211-S214.
Step S211, when the receiving interface receives the target packet, the target packet is sent to the protocol stack.
The method comprises the steps of setting an existing protocol stack in a kernel mode of an operating system, setting a plurality of protocol communication modules and corresponding processing rules in the protocol stack, and directly uploading a target message to the existing protocol stack in the operating system when a receiving interface of a network card in the operating system receives the target message so as to directly process the target message without constructing a new protocol stack in an application state for processing.
Step S212, searching in the target message based on the processing rule of the protocol stack, and determining a forwarding table corresponding to the target message.
If the processing rule detects that the target message is an established connection, for example, a TCP (Transmission Control Protocol, a connection-oriented, reliable and byte-stream-based transport layer communication protocol) connection or a UDP (User Datagram Protocol, user data packet protocol) connection is established, and a method for sending an encapsulated IP data packet without establishing a connection is provided for an application program, the message data flow is searched in the message data flow, and a forwarding table corresponding to the target message can be searched and determined, where the forwarding table may be a session (session control) table, and attributes and configuration information required by a specific user session are stored.
Step S213, determining a transmitting interface corresponding to the target message based on the forwarding table, so as to transmit the target message according to a transmitting function of the transmitting interface.
The forwarding table finds a sending interface when the target message is sent, and can also call a sending function of the sending interface to send the target message.
Step S214, setting the value of the second identifier from the default value to a non-default value, to obtain a first set identifier, where the first set identifier and the first identifier are used as the adjustment identifier information.
When a sending function of a sending interface is called to send a target message, the target message can be sent in a fast forwarding mode, and the forwarding state of the target message is changed, so that a value of a second identifier representing whether the target message is fast forwarded needs to be set from a default value 0 representing non-fast forwarding to a non-default value 1 representing fast forwarding to obtain a first set identifier, the first set identifier is used for representing that the target message is sent in the fast forwarding mode, the identifier information can be correspondingly adjusted in real time according to the forwarding state of the target message, and the first identifier and the first set identifier are used as adjustment identifier information.
Optionally, when the sending interface is not used to send the target message, the first set identifier is set to the default value of the second identifier.
When the sending interface and the sending function are not called to send the target message, the target message is not forwarded quickly, and can be forwarded in a common forwarding mode, and a second identifier of whether the target message is forwarded quickly in the identifier information is unchanged compared with a default value, so that the forwarding state of the target message is unchanged, the second identifier does not need to be adjusted, and the first setting identifier is directly set to the default value of the second identifier, so that the forwarding state of the target message which is not forwarded quickly is marked.
In the embodiment shown in fig. 4, the time for constructing the protocol stack can be reduced, so that the forwarding time of the message data is reduced, and the identification information can be adjusted in real time according to the change of the forwarding state of the message data, so as to improve the forwarding performance of the message data.
Optionally, referring to fig. 5, fig. 5 is a detailed flowchart of step S220 provided in the embodiment of the present application, and step S220 may further include steps S221-S223.
Step S221, after the receiving interface receives the preset number of the target packets, generating an allocation instruction.
After the receiving interface receives the target messages with the preset number, the buffer structure body is required to be in larger quantity when the receiving interface sends the target messages with larger number. It is therefore necessary to generate corresponding allocation instructions to allocate the cache structure for the target message that needs to be replenished, as the cache structure has already been used.
Step S222, in response to the allocation instruction, determines whether to allocate a supplemental cache structure according to the values of the first flag and the first set flag in the adjustment flag information.
Wherein after responding to the allocation instruction, the allocation flow is opened. And acquiring the forwarding state of the received target message according to the values of the first identifier and the first set identifier in the adjustment identifier information, so as to determine whether a new supplementary cache structure body needs to be allocated for supplementation according to the current forwarding state of the target message.
Step S223, determining the target cache structure and the target identification information when the target message is sent based on the allocation result of the supplemental cache structure.
The method comprises the steps of determining a target cache structure body and target identification information corresponding to a target message when the target message is sent according to different results, wherein two distribution results exist during distribution and non-distribution, and accordingly obtaining a forwarding state of the target message when the target message is sent.
Optionally, when the values of the first identifier and the first set identifier are both non-default values, no supplemental cache structure is allocated; and the target cache structure body is used for adjusting the identification information to serve as target identification information when the cache structure body is used as the target message for sending.
When the values of the first identifier and the first set identifier are both non-default values, namely are both 1, the target message is rapidly forwarded and is sent completely, and a new supplementary cache structure body is not required to be allocated to the target message. And when the target message is transmitted, the buffer structure body is directly used as the target buffer structure body in the transmission, and compared with the state before transmission, the forwarding state of the target message is not changed, and the adjustment identification information can be directly used as the target identification information in the transmission.
Optionally, when the values of the first identifier and the first set identifier are not both non-default values, allocating a supplementary cache structure body; setting the numerical value of the first identifier to be a non-default value to obtain a second set identifier; and the target cache structure body when the cache structure body and the supplementary cache structure body are used as target messages is used as target identification information, and the second set identification and the first set identification are used as target identification information.
When the values of the first identifier and the first set identifier are not both non-default values, three cases can be classified as follows: 1. the first mark is 0, and the first set mark is 0, so that the target message is not transmitted in a fast forwarding mode and is not transmitted completely, and a new supplementary cache structure body is required to be allocated to the target message for transmission; 2. the first identifier is 0, and the first set identifier is 1, so that the target message is sent in a fast forwarding mode when being sent, but the target message is not sent completely, and therefore a new supplementary cache structure body is required to be allocated to the target message for sending; 3. the first flag is 1, and the first set flag is 0, which indicates that the target message is not sent in a fast forwarding manner when being sent, and a new supplementary buffer structure body needs to be allocated to the target message although the sending is completed.
Optionally, when a new supplementary buffer structure body needs to be allocated to the target message, the supplementary buffer structure body and the original buffer structure body are converted into structure bodies as targets when the mechanical energy of the target message is transmitted. Setting the value of the first identifier, setting the first identifiers with the value of a default value or a non-default value as the non-default value, obtaining a second set identifier with the value of the non-default value, and using the first set identifier and the second set identifier as target identifier information when the target message is sent, so as to represent the forwarding state of the target message which can be sent completely when the target message is sent on the basis of the target cache structure obtained by supplementing.
It should be noted that, by adjusting the value of the variable in the identification information to determine whether to supplement the new buffer structure in the buffer, it is not necessary to supplement all the message data, and targeted supplement can be achieved, so that the allocation pressure of the buffer structure and the memory pressure of the buffer can be reduced.
In the embodiment shown in fig. 5, the target cache structure body and the target identification information carried in the target cache structure body are determined when the target message is sent in the sending interface. The buffer area after the target message is received can be adjusted, and data transmission is performed on the basis of the adjusted target message.
Optionally, referring to fig. 6, fig. 6 is a detailed flowchart of step S230 provided in the embodiment of the present application, and step S230 may further include steps S231-S233.
Step S231, after the transmission interface finishes transmitting the target packet, extracting the target identification information from the target cache structure body.
After the sending interface finishes sending the target message on the basis of the target cache structure body and the target identification information, the forwarding state of the target message during sending can be obtained on the basis of the numerical value of the identification variable in the target identification information by extracting the target identification information.
And step S232, when the target identification information is the first identification and the first set identification, the target identification information is not set, and multiplexing is performed on the target cache structure body.
If the target identification information is the first identification and the first set identification, that is, if the target identification information is 1, the first identification is not set, the target identification information is not set, which means that the target message is sent in a fast forwarding manner and the sent target cache structure corresponding to the target message can be reused, and the target cache structure is directly and fast multiplexed.
Optionally, after the target cache structure is quickly multiplexed, the first identifier in the target cache structure can be reset to a default value, and the first identifier is matched to a receiving buffer of a new target message for continuous use.
And step S233, setting the target identification information when the target identification information is the second set identification and the first set identification, and recovering the target cache structure.
When the target identification information is the second set identification and the first set identification, the first identification is set to be the second set identification, and the target identification information is set, which means that the target message is not forwarded quickly or is not sent completely in the fast forwarding process, and the sent target cache structure body cannot be reused in the case and needs to be recovered to the operating system to be distributed again by the operating system.
When forwarding the target message in a fast forwarding manner, for example, 60% of the target buffer structure bodies can be rapidly multiplexed, so that 30% of message data forwarding performance in an operating system is improved, the number of message buffers in a kernel state is effectively reduced, the memory pressure in the kernel state is reduced, and the method can be applied to network card drives of various versions, is not limited by hardware forms, is suitable for various devices, and meets various requirements of users.
In the embodiment shown in fig. 6, by the forwarding state of the target packet during forwarding, whether the buffer area can be multiplexed can be rapidly and accurately determined, so that the target buffer structure body can be multiplexed and recycled correspondingly.
