Background
After the network device receives the message, the session corresponding to the message needs to be acquired, and the message is operated according to the session content, so that the message is processed. The current method for processing the message mainly comprises the following steps: and storing the session through a DRAM in the CPU, and acquiring the session corresponding to the message through the CPU after receiving the message, thereby obtaining the session content corresponding to the message and processing the message.

Moreover, because each message is processed by the CPU, the CPU needs to search for a matching session in the DRAM, and when the number of messages is large, the speed of processing the messages by the CPU is limited by the speed of the DRAM of the read/write system, so that the CPU is in an idle state, thereby affecting the working efficiency of the CPU and the processing efficiency of the messages.

For convenience of description, some terms or expressions referred to in the embodiments of the present application are explained below:
an Ethernet port: a port for a network data connection.
PCIe bridge: i.e., PCIe lanes, can be used for data transmission, and the main advantage is high data transmission rate.
According to an embodiment of the present application, a data transmission method is provided.
Fig. 1 is a flowchart of a data transmission method according to an embodiment of the present application. As shown in fig. 1, the method comprises the steps of:
step S102, obtaining the message received by the network receiving port, and extracting the message characteristic of the message.
It should be noted that the acceleration chip may be used to obtain the message, where the acceleration chip may be an FPGA (Field Programmable Gate Array) chip or an ASIC (Application Specific Integrated Circuit) chip. Fig. 2 is a system architecture diagram corresponding to an optional data transmission method provided in an embodiment of the present application, and as shown in fig. 2, an acceleration chip is connected to a network receiving port, a network sending port, a CPU, and a session library, respectively, and the acceleration chip may acquire a message received by the network receiving port, send the message to the network sending port, and also acquire session information in the session library.
Specifically, after obtaining the packet received by the network receiving port, the acceleration chip may obtain feature information in the packet information, for example, obtain quintuple information in the packet information, so as to obtain session information corresponding to the packet from the session library according to the quintuple information.
In order to avoid frequently obtaining session information from the CPU, optionally, in the data transmission method provided in the embodiment of the present application, before determining whether the session information corresponding to the message feature exists in the target session library, the method further includes: acquiring a plurality of pieces of preset session information, and acquiring a preset hash value generated by quintuple information of each piece of preset session information to obtain a plurality of preset hash values; packing a plurality of pieces of preset session information into a preset session information set, wherein each piece of preset session information is associated with a corresponding preset hash value; and storing each piece of preset session information in the preset session information set into a session space corresponding to the associated preset hash value through the CPU to obtain a target session library.
It should be noted that, since the session information corresponding to each acquired packet needs to be acquired from the CPU cache, in order to reduce the CPU occupancy, part of the commonly used session information may be stored in the session library, and the session information corresponding to the packet is directly acquired in the session library according to the quintuple information after the acceleration chip receives the packet and acquires the quintuple information, thereby avoiding acquiring the session information through the CPU, and improving the acquisition efficiency of the session information.
Specifically, the preset session information may be session information with a higher called frequency, five-tuple information of each piece of session information is acquired, and then a hash value may be generated according to a preset calculation rule according to data in the five-tuple information, so as to obtain a hash value corresponding to each piece of preset session information. And then, packaging all the preset session information, and sending the preset session information set to a session library through the acceleration chip.
Further, a session library may store session information by using a data structure of a fixed hash table, each hash value corresponds to the same amount of session information, and fig. 3 is a schematic diagram of an optional fixed hash table provided according to an embodiment of the present application, where as shown in fig. 3, a chain table head of each hash chain is a hash value, session spaces included in each hash chain are the same, and each session space stores one piece of session information. After the preset session set is sent to the session library, the session library generates a corresponding hash chain and a fixed number of session spaces according to the hash value of each preset session information in the preset session set, at this time, each preset session information can be determined according to the hash value and stored in the corresponding session space, and the storage position is returned to the CPU, so that the CPU can obtain the position where each session information is stored, thereby obtaining the target session library.
It should be noted that, when the hash table is used to store session information, the session storage space corresponding to each hash value in the hash table is usually not limited in number, that is, when the number of session information with the same hash value is very large, the number of session storage space corresponding to each hash value is also very large, so that when the session information is read, since the number of session information is unknown, after the hash value is obtained, it is necessary to sequentially perform traversal comparison on each session information in the hash chain table corresponding to the hash value, and after the comparison is successful, obtain the session information. However, this method needs to consume a lot of time in the process of traversing the narrative session information, which affects the efficiency of message processing. In the technical scheme, the fixed hash table is used for storing the session information, at the moment, when the session information is acquired, the session information can be directly acquired according to the storage position of each session, and the session information is acquired from the CPU when the corresponding session information is not stored in the session library, so that the pipeline operation for processing the message can not be influenced by time delay generated by traversal, and the message processing efficiency is improved.
And step S104, judging whether the session information corresponding to the message characteristics exists in the target session library.
Specifically, after the target session library is generated, after the message is received and the quintuple information corresponding to the message is obtained, traversal may be performed in the session library according to the quintuple information, so as to obtain the session information corresponding to the message.
In order to determine whether the session library has session information corresponding to a packet quickly and accurately, optionally, in the data transmission method provided in the embodiment of the present application, the packet characteristics include quintuple information, and determining whether the session information exists in the target session library includes: generating a hash value according to the quintuple information; judging whether session information corresponding to the hash value is stored in the target session library; under the condition that the session information corresponding to the hash value is not stored in the target session library, determining that the session information corresponding to the message characteristics does not exist in the target session library; respectively acquiring quintuple information of each session information under the condition that at least one session information corresponding to the hash value is stored in the session library to obtain at least one target quintuple information; judging whether quintuple information identical to the quintuple information exists in at least one target quintuple information or not; determining that session information corresponding to message characteristics does not exist in a target session library under the condition that five-tuple information identical to the five-tuple information does not exist in at least one target five-tuple information; and determining that the session information corresponding to the message characteristics exists in the target session library under the condition that five-tuple information identical to the five-tuple information exists in at least one target five-tuple information.
Specifically, after the quintuple information of the packet is obtained, a hash value corresponding to the packet may be generated according to the quintuple information by a preset calculation rule, and the hash value is traversed in the target session library, so as to determine whether a hash chain having the same hash value as the packet exists in the target session library, and in the absence of a hash chain having the same hash value as the packet, it is determined that the session information corresponding to the packet is not stored in the target session library, and in the presence of a hash chain having the same hash value as the packet, the quintuple information of each session information in the hash chain is obtained, and the quintuple information of each session information is compared with the quintuple information of the packet, and in the presence of the same quintuple information of the session information as the quintuple information of the packet, the session information corresponding to the packet may be obtained, and in the absence of the same quintuple information as the packet, then the session information corresponding to the message is judged not to be stored in the target session library. The embodiment achieves the purpose of rapidly and accurately determining whether the session information corresponding to the message exists in the target session library, thereby improving the acquisition efficiency of the session information.
And step S106, acquiring the session information under the condition that the session information exists in the target session library, and sending the message to a network sending port indicated by the session information.
Specifically, when the session information corresponding to the message exists in the target session library, the session information may be directly obtained through the acceleration chip, and the content in the session information is read, so as to perform a corresponding operation on the message, for example, perform an operation such as correspondingly modifying the message content, designating a destination port for sending the message, and so on, so as to send the message information to the network sending port indicated in the session information, thereby performing a corresponding operation on the message, so that the network sending port may receive the message after the corresponding operation is performed.
And S108, under the condition that the session information does not exist in the target session library, sending the message to the CPU, receiving the target session information and the message returned by the CPU, and sending the message to a network sending port indicated by the target session information according to the target session information, wherein the target session information is the session information generated by the CPU according to the message.
Specifically, under the condition that the session information corresponding to the message does not exist in the target session library, the acceleration chip needs to send the message to the CPU, and obtains the session information corresponding to the message in the CPU cache, after the acceleration chip sends the message to the CPU, the acceleration chip does not hold the message but forwards the message to the CPU, under the condition that the CPU cache also has no session information corresponding to the message, the CPU can generate target session information corresponding to the message according to a corresponding program, and sends the message and the target session information to the acceleration chip, the acceleration chip can execute corresponding operation to the message according to the target session information, and sending the message to a corresponding network sending port, wherein the network sending port may be carried in the target session information, or the network sending port may be sent to the acceleration chip together when the CPU sends the message and the target session information to the acceleration chip.
According to the data transmission method provided by the embodiment of the application, the message received by the network receiving port is obtained, and the message characteristic of the message is extracted; judging whether session information corresponding to the message characteristics exists in a target session library or not; under the condition that the session information exists in the target session library, acquiring the session information and sending the message to a network sending port indicated by the session information; and under the condition that the session information does not exist in the target session library, sending the message to the CPU, receiving the target session information and the message returned by the CPU, and sending the message to a network sending port indicated by the target session information according to the target session information, wherein the target session information is the session information generated by the CPU according to the message. The problem of low efficiency of processing the message through the CPU in the related technology is solved. By setting the session library, part of the session information is stored in the session library, whether the session information corresponding to the message is in the session library is judged when the message is received, and the session information in the session library can be directly called under the condition of the session library, so that the message does not need to be acquired through a CPU (central processing unit), thereby achieving the effects of reducing the operating pressure of the CPU and improving the processing efficiency of the message.
Optionally, in the data transmission method provided in the embodiment of the present application, the obtaining, by the CPU, each piece of preset session information in the preset session information set to a session space corresponding to the associated preset hash value includes: the CPU stores each piece of preset session information into a session space corresponding to the associated preset hash value through the Ethernet port; or, the CPU stores each piece of preset session information into the session space corresponding to the associated preset hash value through the PCIe bridge.
Specifically, because the session library used in the technical scheme stores the session information by using the data structure of the fixed hash table, the address information of the session space corresponding to each piece of session information in the session library is known in the CPU, so that when the CPU sends the session information to the session library, the session information can be directly sent to the session library according to the known address information in the CPU without first obtaining the address information of the session information, and therefore, two data transmission methods, namely an ethernet port with low stability and a PCIe bridge with high stability, can be used for data transmission, thereby avoiding the phenomenon that the session information cannot be sent to the session library under the condition that the PCIe bridge is abnormal, and ensuring the timeliness of data transmission.
Optionally, in the data transmission method provided in the embodiment of the present application, before determining whether session information corresponding to a message feature exists in the target session library, the method further includes: judging whether the message carries a preset identifier or not; under the condition that the session information carries a preset identifier, the steps of sending the message to a CPU and sending the message to a network sending port indicated by the session information in the CPU are executed; and under the condition that the session information does not carry a preset identifier, executing the step of judging whether the session information corresponding to the message characteristics exists in the target session library.
Specifically, since the message stored in the session library corresponding to the session information may need to be specially managed during a certain transmission, after the message is received, it may be determined whether the message carries a preset identifier, and under the condition that the session information carries the preset identifier, it is verified that the message needs to be specially managed, so that the quintuple information is not determined, the message is directly sent to the CPU, and under the condition that the session information does not carry the preset identifier, the quintuple information is continuously obtained and determined. The embodiment achieves the effect of screening the special messages, thereby improving the efficiency of message operation.
Optionally, in the data transmission method provided in the embodiment of the present application, after sending the packet to the CPU and sending the packet to the network sending port indicated by the session information in the CPU, the method further includes: creating a session space corresponding to the hash value in a target session library to obtain a target session space, wherein the session library comprises a plurality of session spaces; and storing the session information into the target session space according to the quintuple information.
Specifically, after the CPU creates the session information corresponding to the packet, the session information may be stored in the target session library, so that when the packet is received again, the session information corresponding to the packet may be directly obtained through the target session library, thereby improving the efficiency of processing the packet.
Optionally, in the data transmission method provided in the embodiment of the present application, before creating a session space corresponding to the hash value in the target session library and obtaining the target session space, the method further includes: judging whether the quantity of the stored session information in the CPU cache is greater than or equal to a preset threshold value or not; under the condition that the number of the session information is larger than or equal to a preset threshold value, a step of creating a session space corresponding to the hash value in a target session library to obtain a target session space is executed; and storing the session information into a CPU cache under the condition that the number of the session information is less than a preset threshold value.
Specifically, since the CPU needs to perform a write operation to store the session information into the session library, the CPU may frequently work by immediately transmitting the session information into the session library every time one session information is generated, thereby affecting the operating efficiency of the CPU. Therefore, after one piece of session information is generated, the session information can be stored in the CPU cache, and after a preset number of pieces of session information are cached in the CPU cache, a plurality of pieces of session information are packaged and sent to the session library, so that the CPU can store a large number of pieces of session information into the session library only by performing one-time writing operation, the operation amount of the CPU is reduced, and the execution efficiency of the CPU is improved.
It should be noted that the steps illustrated in the flowcharts of the figures may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowcharts, in some cases, the steps illustrated or described may be performed in an order different than presented herein.
