However, the integrated device cannot identify whether the received message is a transport layer protocol message or a data link layer protocol message, resulting in the inability to accurately transmit the message.

In view of this, embodiments of the present application provide a message processing method to solve problems existing in the prior art. First, the system architecture of the application of a message processing method provided by the embodiment of the present disclosure is introduced.

The technical solutions provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings of the description, taking the network card as an example of the network device, and using the network card as the execution subject.

Referring to Figure 4, an embodiment of the present application provides a schematic diagram of a network architecture, which includes the data link layer to which the embodiment of the present application is applied. It also includes the physical layer, network layer, transport layer, session layer, presentation layer and application layer. Of course, Figure 4 only shows a schematic diagram of a seven-layer network architecture. Other network architectures may include only the physical layer, data link layer, network layer, transport layer and application layer. Therefore, the embodiments of this application do not limit the network architecture involved.

The technical principle of the embodiment of this application is: when the network card driver receives a message from the communication device, the communication device will remind the network card driver to receive the message by triggering a hard interrupt of the network card. When the network card driver detects that the hard interrupt of the network card is triggered, After that, execute the corresponding interrupt response. In the embodiment of the present application, a hook function is added to the network card driver program. When the network card driver detects that the hard interrupt of the network card is triggered and receives a message from the communication device, the hook function is immediately scheduled for execution. The network card driver calls this hook function to analyze and shunt the message type based on the linked list rules. If it is a packet of the transport layer protocol, the network card driver will push the packet to the protocol stack to complete subsequent network layer processing; if it is a packet of the data link layer protocol, the network card driver will push the packet to the protocol stack and transmit it directly to user layer. Therefore, the embodiments of the present application can realize packet identification and offloading at the data link layer through hook functions.

In addition, the method provided by the embodiment of this application also provides a principle of debugging and printing of messages. In fact, during the packet processing based on the above technical principles, the network card driver captures the packets before the hook function is called and after the offload processing according to the instructions corresponding to the debugging parameters determined in advance, so as to compare the two packets. , to facilitate product debugging and application.

Illustratively, referring to Figure 5, combined with the above principles, an embodiment of the present application provides a message receiving processing flow. Message reception and processing are mainly at the mac layer and protocol stack layer. The reception processing of messages in the mac layer includes: when the terminal device has a message that needs to be received by the network card, the hardware interrupt of the network card will be triggered to notify the network card to receive the message. After that, the network card driver responds to the hard interrupt of the network card to receive the message, and at the same time calls the hook function to identify the type of the message (here, the purpose of identifying the message type is to shunt the message based on the type of the message) . At this time, the messages before the hook function is called and after the offload processing can be captured based on the debugging parameters. Then, the offloaded message is reported to the kernel protocol stack (i.e., protocol stack) at the protocol stack layer for corresponding processing. Finally, notify the user layer to receive the message. It should be noted that Figure 5 only briefly summarizes the contents of the message receiving process, and the specific description shall prevail.

Referring to FIG. 6 , the message processing method provided by the embodiment of the present application is applied to the network device 02 shown in FIG. 1 . The method of the embodiment of the present application is described in detail below using a network card as an exemplary execution subject instead of the network device. The method specifically includes the following steps.

S11. The network card obtains the first message.

Wherein, the first message is obtained based on the initial message from the communication device.

Optionally, before the network card obtains the packet, the network card driver needs to be initialized in the network platform of the operating system. The specific process is shown in Figure 7. First, the device registration of the network platform of the network card is performed. After that, perform driver registration for the network platform. Then, initialize the rule list header of the network card driver and configure the label function. After the configuration is completed, the network card driver initialization is completed. Specifically, the rule list header initialization adds a single-link list management function to the network card driver, which is used to take over the linked list rules configured by the user layer. The linked list rules are mainly used for rule matching processing of data link layer packets. This processing user layer Another driver interface will be called to deliver to the network card driver the linked list rules of the packets that the user expects to receive. The linked list rules include the correspondence between the feature information and types of the packets; the feature information includes the source address and packet type used to characterize the packets. At least one of the destination address and network type of the document; such as mac address, IP address, or protocol and other field information. The network card driver will compare the field information contained in the linked list rule with the field information in the currently received message. If the field information in the currently received message contains the field information contained in the linked list rule, then The match is successful; otherwise, the match fails. Secondly, the label function configuration of the network card driver is used to enable the network card to add label information to the packet. The specific content of the label information can refer to various types of switches from current mainstream manufacturers. It is not limited to specific switches. Please refer to its data manual for configuration. These label information are added to the packet by the switch chip in the network card. It should be noted that Figure 7 only briefly summarizes the initialization process of the network card driver, and the specific description shall prevail.

Optionally, the network card obtaining the first message specifically includes: the network card receives the initial message from the communication device; and determines whether the initial message contains label information.

If it is included and the label information is accurate, the initial message is determined to be the first message.

and/or, if included and the label information is wrong, determine the new label information based on the transmission information of the initial message, use the new label information to update the label information in the initial message, and determine that the updated initial message is the One message. Among them, the transmission information includes new label information.

And/or, if it is not included, determine the label information based on the transmission information of the initial message, add the label information to the initial message, and determine that the initial message after adding the label information is the first message.

In fact, there are two ways to obtain the first message:

The first method: the communication device adds label information by itself during the process of generating the initial message. Therefore, when the network card receives the initial message, it first determines whether the label information in the initial message is accurate, that is, by determining whether the content of the label information is consistent with the transmission information of the initial message; for example, by comparing the labels Check whether the port number in the information is consistent with the port number when the initial message was transmitted. If it is accurate, then the initial message is the first message; if it is inaccurate, then at least determine a new label information based on the port through which the communication device transmits the initial message and the network to which the port belongs (ie, the transmission information), and use the new label information Update the label information in the initial message. and determine the updated initial message as the first message. It should be noted that the above is not limited to determining whether the label information in the initial message is accurate by comparing whether the port number in the label information is consistent with the port number when the initial message is transmitted. For example, you can also determine whether the label information in the initial message is accurate by comparing whether the network to which the port in the label information belongs is consistent with the network to which the port belongs when the initial message is transmitted. Therefore, the embodiment of the present application does not place any limitation on the method of determining whether the label information in the initial message is accurate.

The second method: the communication device does not add label information in the process of generating the first message. The network card at least determines a label information based on the port through which the communication device transmits the first message and the network to which the port belongs, adds the label information to the initial message, and determines the added initial message as the first message.

It should be noted that, combined with Figure 2, for the above two methods, the process of obtaining the first message in the network card includes: the Switch chip receives the initial message sent by the communication device through the physical port Xn, and the Switch chip converts the initial message according to the above There are two ways to determine the first message.

S12. The network card determines the type of the first message based on the linked list rules.

Among them, the type includes the packets of the transport layer protocol or the packets of the data link layer protocol; the linked list rules include the correspondence between the characteristic information of the message and the type; the characteristic information includes the source address used to characterize the message, the At least one of destination address and network type.

Optionally, based on the linked list rule, determining the type of the first message specifically includes: matching the linked list rule with the first message, and the matching results include: if the match is successful, determining the type of the first message is data link. A packet of a transport layer protocol; if the match fails, the type of the first packet is determined to be a packet of a transport layer protocol. It should be noted that the linked list rules in the embodiment of this application are configured for packets of the data link layer protocol.

Specifically, the network card determines the type of the first message based on the linked list rules, mainly by querying and matching the linked list rules issued by the user layer (that is, the attribute fields of the messages that the user expects to receive). If the configured linked list rules are queried, It means the match is successful. For example, if the linked list rule issued by the dest_mac user is the same as the dest_mac address field extracted from the received message, then the match is successful. The successfully matched packets are packaged according to the packets of the data link layer protocol, and the configuration information is added based on the mac layer. Otherwise, directly report the mac layer message in TCP/IP format to the kernel protocol stack, which is the standard TCP/IP mac layer packet format.

Furthermore, the linked list rules are generated through another driver. The linked list rule configuration driver framework shown in Figure 8 is a character device driver that has nothing to do with the physical layer. From top to bottom, it includes the user layer and the driver layer. The user layer is used to provide users with an interface for adding and deleting linked list rules. The driver layer registers character devices and encapsulates operation sets to provide and process the added linked list rules and deleted linked list rules for the user layer. Among them, the linked list rules include but are not limited to one or more items as shown in Table 1 below.

Table 1

Source code address 6 bytes Source code address masking length Object code address 6 bytes Destination address mask length Network Type Network type mask length Source IP address Source IP address mask length Destination IP address Destination IP address mask length Custom tag type tag type

S13. The network card determines the target message according to the type of the first message and transmits the target message.

Specifically, when the type of the first message is a transport layer protocol message, the label information of the first message is determined, the label information is deleted from the first message, and the target message is generated. And/or, when the type of the first message is a data link layer protocol message, determine the first message as the target message.

In the application, when the target message is a data link layer protocol message, the sending and receiving processing is performed at the data link layer. The generated target message does not need to be processed anymore and can be transmitted to the user layer through the protocol stack. If the target message is a transport layer protocol message, it needs to be transmitted to the network layer through the data link layer for processing.

It should be noted that the format of the first message involved in the embodiment of this application is the same as the format of the message of the data link layer protocol. The format of the second message is the same as the format of the transport layer protocol message; but after matching the second message based on the linked list rule, the type of the second message can be a data link layer protocol message or a transport layer protocol message. arts. When the type of the second message is a data link layer protocol message, the previously deleted label information in the first message needs to be re-added to the second message to generate the target message. At this time, the target message The format of the message is the message format of the data link layer protocol; when the type of the second message is the message of the transport layer protocol, the second message is the target message, and the format of the target message is the transport layer protocol. The message format of the protocol.

In the above method, through link rule matching, it can be accurately identified that the message that the user needs to upload is a data link layer protocol message or a network layer standard transport layer protocol message. This solves the problem that the existing integrated equipment cannot identify whether the received message is a transport layer protocol message or a data link layer protocol message. In order to achieve accurate offload processing of messages under the corresponding type through the type of the message.

In one implementation, with reference to Figure 6 and Figure 9, S12 specifically includes the following implementation:

S121. The network card determines the label information of the first message; the label information is at least used to identify the port through which the communication device transmits the initial message and the network to which the port belongs.

The network card determines the label information of the first message; the label information is at least used to identify the port through which the communication device transmits the first message and the network to which the port belongs.

Optionally, the network card calls a hook function to parse the first message and determine the label information.

The label information includes: the number of the communication device, the port number of the communication device, the network to which the port of the communication device belongs, and the priority setting of the network.

For example, the length of the tag information in the message is generally 6 bytes. It can contain 2-byte tag_id (such as 0x9126) and 4-byte tag data information. The tag data information includes 1 byte of source device number, 1 byte of source device port number, 1 byte of priority and the high 4 bits of VLAN identification (VID), and the low 8 bits of 1 byte of VID. Among them, the source device number indicates which device the packet was received from; the source device port number indicates which port of the device the packet was received from; and the priority indicates the priority of the virtual local area network (VLAN) of the port. Setting; the high 4 bits and low 8 bits of VID indicate which VLAN the port receiving the packet belongs to.

S122. The network card deletes the label information and generates a second message.

Further, after determining the label information in the first message, the network card first stores and manages the label information, and then deletes the label information in the first message.

Specifically, the network card deletes the label information in the first message by calling a hook function and generates the second message.

S123. The network card determines the type of the second message based on the linked list rule, and uses the type of the second message as the type of the first message.

Optionally, based on the linked list rule, determining the type of the second message specifically includes: matching the linked list rule with the second message, and the matching results include: if the match is successful, determining the type of the second message is data link. If the match fails, the type of the second packet is determined to be a packet of the transport layer protocol. It should be noted that the linked list rules in the embodiment of this application are configured for packets of the data link layer protocol.

Specifically, the network card determines the type of the second message based on the linked list rules, mainly by querying and matching the linked list rules issued by the user layer (that is, the attribute fields of the messages that the user expects to receive). If the configured linked list rules are queried, It means the match is successful. For example, if the address field contained in the linked list rule issued by the dest_mac user is the same as the dest_mac address field extracted from the received message, the match is successful. The successfully matched packets are packaged according to the packets of the data link layer protocol, and the configuration information is added based on the mac layer. Otherwise, directly report the mac layer message in TCP/IP format to the kernel protocol stack, which is the standard TCP/IP mac layer packet format.

On the basis of S121-S123, determine the target message according to the type of the first message, including: when the type of the first message is a transport layer protocol message, add label information to the second message , generate the target message. And/or, when the type of the first message is a data link layer protocol message, determine the second message as the target message.

Further, the hook function is called to parse the second message and determine the label information.

In this implementation, considering that the packet types of transport layer protocols account for the majority, by deleting the label information from the first packet and then matching the link rules, the packets that the user needs to upload can be accurately identified. It is a packet of a data link layer protocol or a packet of a standard transport layer protocol of the network layer. This solves the problem that the existing integrated equipment cannot identify whether the received message is a transport layer protocol message or a data link layer protocol message. In order to achieve accurate offload processing of messages under the corresponding type through the type of the message.

In one implementation, referring to Figure 9, if the type of the second message is a data link layer protocol message. Specifically include:

S101. The network card transmits the target message to the user layer through the protocol stack; the target message is the first message.

Specifically, the required linked list rules are first added through the user layer provided by the character device driver. The character device driver transmits the linked list rules to the network card driver through a preset interface with the network card driver. After that, when the network card driver executes recv to receive the message through the socket, it obtains the first message, determines the label information of the first message, and stores it. Afterwards, the label information in the first message is deleted to generate a second message. Match the linked list rule with the second message, and determine that the second message contains data corresponding to the linked list element in the linked list rule, then the match is successful. At this time, the deleted label information needs to be re-added to the second message in order to generate a target message that is a data link layer protocol message that needs to be transmitted. The target message is then transmitted to the user layer through the protocol stack.

For example, the format of the label information contained in the first message is as shown in Figure 10 below. The first message includes label information with a length of 6 bytes, a preamble with a length of 7 bytes, and a revelation definition with a length of 1 byte. Delimiter, source mac address with length of 6 bytes, destination mac address with length of 6 bytes, length/type with length of 2 bytes, user data with length, padding field PAD with length of 4 bytes and length of 4-byte frame check sequence FSC. It should be noted that the specific data contained in the 6-byte tag information can be referred to the above, and will not be described again here.

In this implementation, label information is added to the second message, a target message is generated as a message type of the data link layer protocol, and is directly transmitted to the user layer through the protocol stack. In order to achieve accurate transmission of target messages.

In another implementation, referring to Figure 9, if the type of the first message is a transport layer protocol message; specifically:

S102. The network card transmits the second message to the network layer; the second message is the target message.

As an example, take the control message protocol (internet control message protocol, ICMP) Internet link ping packet that needs to be received. The communication device sends an Internet Group Management Protocol (IGMP) request message (i.e., the first message). According to the hardware connection relationship shown in Figure 2, it is received by the switch chip and forwarded to the network card. At this time, the hook function is called up by the network card, and the physical layer tag is stripped (that is, the tag information is deleted. The tag information is different for each manufacturer and can be determined through the respective data manual, so no details are given), and the message is integrated as shown in Figure 11. The second message of the standard network mac message format (that is, the message format of the transport layer protocol). Afterwards, match the linked list rules with the second message. Assuming that the match fails, it is determined that the type of the second packet is a transport layer protocol packet. Then the second message is uploaded to the network layer of the protocol stack, and the network layer of the protocol stack receives the second message and replies with a response message to realize the process of link pinging.

Among them, matching failure may be caused by the user not generating linked list rules through the character device driver. It is also possible that a linked list rule is generated, but the data in the linked list rule cannot correspond to the data in the second message. If the filled message type type=0x8899 is inconsistent with the actual type of the received message 0x0800, it will be reported to the protocol stack according to the standard format.

In this implementation, the second message that fails to match is uploaded to the network layer without any processing, thereby achieving accurate transmission of the target message.

In one implementation, before receiving the first message from the communication device, the process includes: receiving debugging parameters input by the user; the debugging parameters are used to instruct the capture of the received and transmitted messages of the MAC layer; receiving the third message from the communication device. After one message, it includes: capturing the first message and the target message based on the debugging parameters. Determine the difference between the first message and the target message.

It should be noted that for the description of this implementation, refer to the description corresponding to Figure 7 above, and will not be described again here.

In this implementation, the packets received by the mac layer and the packets transmitted are captured by adjusting parameters set in advance, so as to determine the information changes of the previous and later packets by comparing the previous and later packets.
