However, the integrated device cannot identify whether the received message is a message of a transport layer protocol or a data link layer protocol, which results in that the message cannot be accurately transmitted.

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

In an implementation manner, an embodiment of the present application provides a schematic diagram of a hardware structure of a network device (taking the network card 02 shown in fig. 2 as an example). Wherein, network card 02 includes: processor cpu, mac controller and switch chip.

In addition, the sending process and the receiving process of the message are reverse, the sending processing process of the message is mainly packet of the message, the network card 02 passively receives the message transmitted by the protocol layer, so special processing is not needed, and the message can be directly sent to the corresponding terminal device through the physical port xn of the switch chip, which will not be described in detail in the technology.

The transceiver 33 may be any device, such as a transceiver, for communicating with other devices or communication networks, such as an ethernet, a Radio Access Network (RAN), a Wireless Local Area Network (WLAN), etc.

Optionally, the communication device may also include a memory 32.

The technical solution provided by the embodiments of the present application is specifically described below with reference to the drawings of the specification, in which a network card is taken as an example of a network device, and the network card is taken as an execution subject.

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

The technical principle of the embodiment of the application is as follows: when the network card driver receives the message from the communication equipment, the communication equipment can remind the network card driver to receive the message by triggering the hard interrupt of the network card, and after the network card driver detects that the hard interrupt of the network card is triggered, corresponding interrupt response is executed. In the embodiment of the application, a hook function is added in a program driven by a network card. When the network card driver detects that the hard interrupt of the network card is triggered, the hook function is immediately scheduled and executed after the message from the communication equipment is received, and the network card driver analyzes and shunts the type of the message based on the linked list rule by calling the hook function. If the message is a message of a transport layer protocol, the network card driver pushes the message to a protocol stack to complete the processing of a subsequent network layer; if the message is the message of the data link layer protocol, the network card driver pushes the message to the protocol stack to be directly transmitted to the user layer. Therefore, the embodiment of the application can realize message identification and distribution at a data link layer through the hook function.

In addition, the method provided by the embodiment of the application also provides a message debugging and printing principle. In fact, in the process of message processing according to the technical principle, the network card driver captures messages before hook function call and after shunt processing according to the indication corresponding to the debugging parameters determined in advance, so that the two messages are compared, and debugging and application of the product are facilitated.

For example, referring to fig. 5, in combination with the above principle, an embodiment of the present application provides a message receiving processing flow. The message receiving processing is mainly at the mac layer and the protocol stack layer. The receiving and processing of the message in the mac layer comprises the following steps: when the terminal equipment needs the network card to receive the message, the hardware of the network card is triggered to interrupt to inform the network card to receive the message. Then, the network card driver receives the message in response to the hard interrupt of the network card, and calls a hook function to perform type identification on the message (here, the purpose of identifying the message type is to perform shunting processing on the message based on the type of the message). At this time, messages before hook function call and after shunt processing can be captured according to the debugging parameters. And then, reporting the shunted message to a kernel protocol stack (namely a protocol stack) of a protocol stack layer for corresponding processing. And finally, informing the user layer of receiving the message. It should be noted that fig. 5 only briefly summarizes the content of the message receiving process, and the above description is taken as the standard.

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

S11, the network card acquires the first message.

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

Optionally, before the network card acquires the message, the network card driver needs to be initialized in the network platform of the operating system. Referring to fig. 7, a device registration of the network platform of the network card is performed first. And then, performing drive registration of the network platform. And then, initializing a rule chain table head driven by the network card and configuring a label function. And after the configuration is completed, the network card driver is initialized. Specifically, the rule chain table header initialization is to add a single chain table management function in the network card drive, and is used for taking over the chain table rule configured by the user layer, the chain table rule mainly performs rule matching processing on the message of the data link layer, the processing user layer calls another drive interface to issue the chain table rule of the message expected to be received by the user to the network card drive, and the chain table rule comprises the corresponding relation between the characteristic information and the type of the message; the characteristic information comprises at least one of a source address for representing the message, a target address of the message and a network type; such as mac address, IP address, or protocol. The network card driver compares the field information contained in the linked list rule with the field information in the currently received message, and if the field information in the currently received message contains the field information contained in the linked list rule, the matching is successful; otherwise, the matching fails. And secondly, the label function configuration driven by the network card is used for realizing the addition of label information in the message by the network card. The specific content of the label information can refer to various types of switches of the current mainstream manufacturers, is not limited to a specific switch, and is configured by referring to a data manual. The label information is added in the message by a switch chip in the network card. It should be noted that fig. 7 only briefly summarizes the initialization processing flow of the network card driver, and the details are based on the above description.

Optionally, the acquiring, by the network card, the first message specifically includes: the network card receives an initial message from the communication equipment; and determining whether the initial message contains label information.

And if the initial message is contained and the label information is accurate, determining that the initial message is the first message.

And/or if the first message contains the new label information and the label information is wrong, determining the new label information according to the transmission information of the initial message, updating the label information in the initial message by using the new label information, and determining the updated initial message as the first message. Wherein the transmission information includes new tag information.

And/or if the first message does not contain the first message, determining label information according to the transmission information of the initial message, adding the label information into the initial message, and determining that the initial message added with the label information is the first message.

Actually, the first packet obtaining method includes the following two ways:

the first mode is as follows: the communication equipment adds the label information in the process of generating the initial message. Therefore, when the network card receives the initial message, whether the label information in the initial message is accurate or not is determined firstly, namely, whether the content of the label information is consistent with the transmission information of the initial message or not is determined; for example, by comparing whether the port number in the tag information is consistent with the port number in the initial message transmission. If the initial message is accurate, the initial message is the first message; if not, determining a new label information according to at least the port of the communication equipment for transmitting the initial message and the network (i.e. transmission information) to which the port belongs, and updating the label information in the initial message by using the new label information. And determining the updated initial message as the first message. It should be noted that the above is not limited to determining whether the tag information in the initial message is accurate by comparing whether the port number in the tag information is consistent with the port number in the initial message during transmission. For example, whether the label information in the initial message is accurate or not may be determined by comparing whether the network to which the port in the label information belongs is consistent with the network to which the port belongs during the initial message transmission. Therefore, the embodiment of the present application does not limit any way of determining whether the tag information in the initial message is accurate or not.

The second mode is as follows: the communication equipment does not add label information in the process of generating the first message. The network card determines label information at least according to the port of the communication equipment for transmitting the first message and the network to which the port belongs, adds the label information into the initial message, and determines the added initial message as the first message.

It should be noted that, with reference to fig. 2, for the above two ways, the process of acquiring the first message in the network card includes: the Switch chip receives an initial message sent by the communication equipment through the physical port Xn, and the Switch chip determines a first message according to the initial message and the two modes.

S12, the network card determines the type of the first message based on the linked list rule.

Wherein, the type comprises a message of a transmission layer protocol or a message of a data link layer protocol; the linked list rule comprises the corresponding relation between the characteristic information and the type of the message; the characteristic information comprises at least one of a source address for characterizing the message, a destination address for the message, and a network type.

Optionally, determining the type of the first packet based on the linked list rule specifically includes: matching the linked list rule with the first message, wherein the matching result comprises the following steps: if the matching is successful, determining the type of the first message as a message of a data link layer protocol; and if the matching fails, determining that the type of the first message is a message of a transport layer protocol. It should be noted that the linked list rule in the embodiment of the present application is configured for a packet of a data link layer protocol.

Specifically, the network card determines the type of the first message based on the linked list rule, and mainly performs query and matching on a user layer issued linked list rule (i.e. an attribute field of a message which the user expects to receive), and if the configured linked list rule is queried, the matching 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, the matching is successful. And packaging the successfully matched messages according to the message packet of the data link layer protocol, and adding configuration information based on the mac layer. Otherwise, directly reporting the mac layer message in TCP/IP format to the kernel protocol stack, namely the mac layer packet format of standard TCP/IP,

further, the linked list rule is generated by another driver, such as the linked list rule configuration driver framework shown in fig. 8, which is a character device driver independent of the physical layer, from top to bottom, including a user layer and a driver layer. The user layer is used for providing an interface for adding and deleting the linked list rules for the user, and the drive layer provides and processes the added linked list rules and the deleted linked list rules and the like for the user layer through registering character equipment and packaging an operation set.

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

Specifically, when the type of the first packet is a packet of a transport layer protocol, the tag information of the first packet is determined, and the tag information is deleted from the first packet, so as to generate a target packet. And/or determining the first message as a target message under the condition that the type of the first message is a message of a data link layer protocol.

In application, when the target message is a message of a data link layer protocol, the target message is transmitted and received at the data link layer, and the generated target message is transmitted to a user layer through a protocol stack without being processed again. For the case that the target message is a message of a transport layer protocol, the target message needs to be transmitted to a network layer through a data link layer for processing.

It should be noted that the format of the first packet referred to in the embodiment of the present application is the same as the format of the packet of the data link layer protocol. The format of the second message is the same as that of the message of the transmission layer protocol; however, after the second packet is matched based on the linked list rule, the type of the second packet may be a packet of a data link layer protocol or a packet of a transport layer protocol. When the type of the second message is a message of a data link layer protocol, the label information deleted in the first message is required to be added into the second message again to generate a target message, and the format of the target message is the message format of the data link layer protocol; and when the type of the second message is the message of the transmission layer protocol, the second message is the target message, and the format of the target message is the message format of the transmission layer protocol.

In the method, the message which is required to be uploaded by the user can be accurately identified to be the message of a data link layer protocol or the message of a network layer standard transmission layer protocol in a link rule matching mode. Therefore, the problem that the existing integrated equipment can not identify whether the received message is the message of a transmission layer protocol or the message of a data link layer protocol is solved. Therefore, the accurate shunting processing of the message under the corresponding type can be realized through the type of the message.

In one implementation, referring to fig. 9 in combination with fig. 6, S12 specifically includes the following implementation manners:

s121, the network card determines the label information of the first message; the label information is at least used for identifying the port of the communication equipment for transmitting 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 for identifying a port of the communication equipment for transmitting the first message and a network to which the port belongs.

Optionally, the network card calls a hook function to analyze the first message, and determines the tag information.

Wherein the tag 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.

Illustratively, the length of the tag information in the message is typically 6 bytes. Which may contain 2 bytes of tag _ id (e.g., 0x9126) and 4 bytes of tag data information. the tag data information includes a source device number of 1byte, a source device port number of 1byte, a priority of 1byte, and an upper 4-bit of a VLAN Identification (VID), and a lower 8-bit of the VID of 1 byte. Wherein the source device number indicates from which device the message was received; the port number of the source equipment indicates that the message is received from the fourth port of the equipment; the priority represents the priority setting of a Virtual Local Area Network (VLAN) of the port; the upper 4 and lower 8 bits of the VID indicate which VLAN the port receiving the packet belongs to.

And S122, deleting the label information by the network card to generate a second message.

Further, after the network card determines the tag information in the first message, the network card firstly performs storage management on the tag information, and then deletes the tag information in the first message.

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

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

Optionally, determining the type of the second packet based on the linked list rule specifically includes: and matching the linked list rule with the second message, wherein the matching result comprises the following steps: if the matching is successful, determining the type of the second message as a message of a data link layer protocol; and if the matching fails, determining that the type of the second message is the message of the transport layer protocol. It should be noted that the linked list rule in the embodiment of the present application is configured for a packet of a data link layer protocol.

Specifically, the network card determines the type of the second message based on the linked list rule, and mainly performs query and matching on the linked list rule (i.e. the attribute field of the message that the user expects to receive) issued by the user layer, and if the configured linked list rule is queried, the matching is successful. For example, if the address field included 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 matching is successful. And packaging the successfully matched messages according to the message packet of the data link layer protocol, and adding configuration information based on the mac layer. Otherwise, directly reporting the mac layer message in TCP/IP format to the kernel protocol stack, namely the mac layer packet format of standard TCP/IP,

on the basis of S121-S123, determining a target message according to the type of the first message, including: and under the condition that the type of the first message is the message of the transport layer protocol, adding label information into the second message to generate a target message. And/or determining the second message as the target message under the condition that the type of the first message is the message of the data link layer protocol.

And further, calling a hook function to analyze the second message and determining the label information.

In the implementation mode, considering that the message types of the transport layer protocol occupy most, the first message deletes the label information, and then the link rule matching is performed, so that the message which needs to be uploaded by the user can be accurately identified to be the message of the data link layer protocol or the message of the transport layer protocol of the network layer standard. Therefore, the problem that the existing integrated equipment can not identify whether the received message is the message of a transmission layer protocol or the message of a data link layer protocol is solved. Therefore, the accurate shunting processing of the message under the corresponding type can be realized through the type of the message.

In one implementation, referring to fig. 9, if the type of the second packet is a packet of a data link layer protocol. The method specifically comprises the following steps:

s101, the network card transmits a target message to a user layer through a protocol stack; the target message is the first message.

Specifically, a required linked list rule is added through a user layer provided by a character device driver, and the character device driver transmits the linked list rule to a network card driver through a preset interface between the character device driver and the network card driver. And then, when the network card drive executes recv receiving message through the socket, acquiring the first message, determining and storing the label information of the first message. And then deleting the label information in the first message to generate a second message. And matching the linked list rule with the second message, and determining that the second message has data corresponding to the linked list elements in the linked list rule, wherein the matching is successful. At this time, the deleted tag information needs to be added again in the second message, so as to generate a target message of the message which needs to be transmitted and is of the type of the data link layer protocol. And then transmitting the target message to a user layer through a protocol stack.

Illustratively, the format of the first message including the tag information is as shown in fig. 10, where the first message includes a tag information having a length of 6 bytes, a preamble having a length of 7 bytes, a start delimiter having a length of 1byte, a source mac address having a length of 6 bytes, a destination mac address having a length of 6 bytes, a length/type having a length of 2 bytes, user data having a length, a PAD field PAD having a length of 4 bytes, and a frame check sequence FSC having a length of 4 bytes. It should be noted that the data specifically included in the 6-byte tag information may refer to the above description, and is not described herein again.

In the implementation mode, the label information is added in the second message to generate a target message which is the message type of the data link layer protocol, and the target message is directly transmitted to the user layer through the protocol stack. So as to realize accurate transmission of the target message.

In another implementation, referring to fig. 9, if the type of the first packet is a packet of a transport layer protocol; the method specifically comprises the following steps:

s102, the network card transmits the second message to a network layer; the second message is a target message.

For example, an Internet Control Message Protocol (ICMP) Internet link ping packet needs to be received. The communication device sends a request packet (i.e., a first packet) of an Internet Group Management Protocol (IGMP), and the request packet is received by the switch chip according to the hardware connection relationship shown in fig. 2 and forwarded to the network card. At this time, the hook function is called by the network card, stripping of the tag of the physical layer is executed (i.e., the tag information is deleted, and the tag information is different from each manufacturer and can be determined by respective data manuals, which are not described in detail), and the message is integrated into the second message in the standard network mac message format (i.e., the message format of the transport layer protocol) as shown in fig. 11. And then matching the linked list rule with the second message. And assuming that the matching fails, determining the type of the second message as a message of a transport layer protocol. And uploading the second message to a network layer of the protocol stack, receiving the second message by the network layer of the protocol stack, replying a response message, and realizing the link ping communication process.

Wherein, the matching failure condition may be that the user does not generate the linked list rule through the character device driver. It is also possible that a linked list rule is generated, but the data of the linked list rule and the data in the second message cannot correspond to each other. If the type of the filled message is not consistent with the actual type 0x0800 of the received message, reporting the protocol stack according to the standard format.

According to the implementation mode, the second message which fails to be matched is uploaded to the network layer without any processing, and accurate transmission of the target message is achieved.

In one implementation, before receiving the first message from the communication device, the method includes: receiving debugging parameters input by a user; the debugging parameters are used for indicating to capture the received and transmitted messages of the MAC layer; after receiving the first message from the communication device, the method includes: and capturing the first message and the target message based on the debugging parameters. Determining a difference between the first message and the target message.

It should be noted that, for the description of the present implementation, reference is made to the description corresponding to fig. 7, and details are not repeated here.

In the implementation mode, the messages received by the mac layer and the transmitted messages are captured through the preset adjustment parameters, so that the information change conditions of the front messages and the rear messages are determined through the comparison of the front messages and the rear messages.
