In the following, with reference to the drawings in the specification, the network device uses a network card as an example, and the network card is taken as an execution body to specifically describe the technical scheme provided by the embodiment of the application.

Referring to fig. 4, a schematic diagram of a network architecture is provided in an embodiment of the present application, where the network architecture 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 one seven-layer network architecture schematic. Other network architectures may include only the physical layer, the data link layer, the network layer, the transport layer, and the application layer. Accordingly, embodiments of the present application are not limited to 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 when the network card driver detects that the hard interrupt of the network card is triggered, the corresponding interrupt response is executed. In the embodiment of the application, a hook function is added in the program of the network card driver. When the network card driver detects that the hard interrupt of the network card is triggered, the hook function is immediately scheduled to execute after receiving the message from the communication equipment, and the network card driver analyzes and shunts the type of the message based on a linked list rule by calling the hook function. If the message is the message of the transmission layer protocol, the network card drive pushes the message to the protocol stack to finish the processing of the 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 the data link layer through the hook function.

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

Referring to fig. 5, in an exemplary manner, in combination with the above principle, a packet receiving process flow is provided in an embodiment of the present application. The message receiving process is mainly carried out at the mac layer and the protocol stack layer. The receiving process of the message in the mac layer comprises the following steps: when the terminal equipment has a message and needs to be received by the network card, triggering the hardware interrupt of the network card to inform the network card to receive the message. Then, the network card driver responds to the hard interrupt of the network card to receive the message, and calls the hook function to identify the type of the message (the purpose of identifying the type of the message is to perform shunting processing on the message based on the type of the message). At this time, messages before the hook function call and after the shunt processing can be grabbed according to the debugging parameters. And then, reporting the shunted message to a kernel protocol stack (namely a protocol stack) of the protocol stack layer for corresponding processing. And finally, informing the user layer to receive the message. It should be noted that fig. 5 only briefly outlines the content of the message receiving flow, and the above description is in particular taken into consideration.

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

S11, the network card acquires the first message.

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

Optionally, before the network card acquires the message, an initialization process of the network card driver needs to be performed in a network platform of the operating system. Referring to fig. 7, the device registration of the network platform of the network card is first performed. And then, carrying out drive registration of the network platform. And initializing a rule chain header of the network card drive and configuring a tag function. After the configuration is completed, the initialization of the network card driver is completed. Specifically, the rule list head initialization is to add a single list management function in the network card driver for taking over the list rule configured by the user layer, wherein the list rule is mainly used for carrying out rule matching processing on the message of the data link layer, the processing user layer can call another driving interface to send the list rule of the message expected to be received by the user to the network card driver, and the 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 used 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 current received message, and if the field information in the current received message contains the field information contained in the linked list rule, the matching is successful; otherwise, the matching fails. Secondly, the label function of the network card driver is configured to realize that the network card adds label information in the message. The specific content of the tag information can refer to various types of switches of the current mainstream manufacturer, is not limited to a specific switch, and is configured by referring to a data manual thereof. The tag information is added in the message by a switch chip in the network card. It should be noted that, fig. 7 only briefly outlines the initialization process flow of the network card driver, and the above description is in particular followed.

Optionally, the network card obtaining the first report specifically includes: the network card receives an initial message from the communication equipment; it is determined whether the initial message contains tag information.

If the initial message is included and the label information is accurate, determining that the initial message is the first message.

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

In practice, the first message acquisition manner includes the following two methods:

the first way is: the communication device adds tag information itself in the process of generating the initial message. Therefore, when the network card receives the initial message, firstly determining whether the label information in the initial message is accurate or not, namely determining whether the content of the label information is consistent with the transmission information of the initial message or not; for example, by comparing whether the port number in the tag information is consistent with the port number at the time of the initial message transmission. If the initial message is accurate, the initial message is a first message; if the information is inaccurate, determining new label information at least according to the port of the communication equipment for transmitting the initial message and the network (namely 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 a first message. It should be noted that, the above is not limited to determining whether the label information in the initial message is accurate or not by comparing whether the port number in the label information is consistent with the port number in the initial message transmission. For example, whether the label information in the initial message is accurate or not can 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 in the initial message transmission belongs. Therefore, the embodiment of the present application does not limit any way to determine whether the tag information in the initial packet is accurate or not.

The second way is: the communication device does not add tag information in the process of generating the first message. The network card determines a piece of label information at least according to the port of the communication equipment 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, referring to fig. 2, for the above two manners, the process of obtaining the first packet in the network card includes: the Switch chip receives an initial message sent by the communication equipment through the physical port Xn, and determines the first message according to the two modes from the initial message.

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 transport 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 used for representing the message, a target address of the message and a network type.

Optionally, determining the type of the first message based on the linked list rule specifically includes: matching the linked list rule with the first message, wherein the matching result comprises: if the matching is successful, determining that the type of the first message is a message of a data link layer protocol; 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, in the embodiment of the present application, the linked list rule is configured for a packet of the data link layer protocol.

Specifically, the network card determines the type of the first message based on the linked list rule, mainly by inquiring and matching the linked list rule issued by the user layer (namely, the attribute field of the message expected to be received by the user), and if the configured linked list rule is inquired, the successful matching is indicated. 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 grouping the successfully matched messages according to the message group of the data link layer protocol, and adding configuration information based on a 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 the standard TCP/IP,

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

Specifically, under the condition that the type of the first message is a message of a transport layer protocol, determining the label information of the first message, deleting the label information in the first message, and generating a target message. And/or determining the first message as the target message under the condition that the type of the first message is a message of a data link layer protocol.

In the application, under the condition that the target message is a message of a data link layer protocol, the data link layer is subjected to receiving and transmitting treatment, the generated target message is not required to be processed again, and the generated target message is transmitted to the user layer through a protocol stack. In 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 for processing through a data link layer.

It should be noted that, in the embodiment of the present application, the format of the first packet 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 message is matched based on the rule of the linked list, the type of the second message may be a message of the data link layer protocol or a message of the transport layer protocol. When the type of the second message is a message of the data link layer protocol, the label information deleted from 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; when the type of the second message is a message of the transport layer protocol, the second message is the target message, and the format of the target message is the message format of the transport layer protocol.

In the method, the message required to be uploaded by the user can be accurately identified as the message of the data link layer protocol or the message of the transmission layer protocol of the network layer standard by the link rule matching mode. The method solves the problem that the existing integrated equipment cannot identify whether the received message is a message of a transmission layer protocol or a message of a data link layer protocol. So as to realize the accurate shunting processing of the message under the corresponding type through the type of the message.

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

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

The network card determines the label information of the first message; the tag information is at least used for identifying a port of the communication device 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 determine 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.

The tag information is typically 6 bytes in length in the message, for example. Which may contain 2 bytes of tag id (e.g., 0x 9126) 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 high 4 bits of a VLAN Identification (VID), low 8 bits of a VID of 1 byte. Wherein the source device number indicates from which device the message was received; the source device port number indicates which port of the message was received from the device; priority indicates the priority setting of the virtual local area network (Virtual Local Area Network, VLAN) of the port; the upper 4 bits and the lower 8 bits of the VID indicate to which VLAN the port receiving the message belongs.

S122, deleting the tag information by the network card, and generating a second message.

Further, after determining the tag information in the first message, the network card firstly stores and manages 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 to generate 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 message based on the linked list rule specifically includes: matching the linked list rule with the second message, wherein the matching result comprises: if the matching is successful, determining that the type of the second message is a message of a data link layer protocol; 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, in the embodiment of the present application, the linked list rule is configured for a packet of the data link layer protocol.

Specifically, the network card determines the type of the second message based on the linked list rule, mainly by inquiring and matching the linked list rule issued by the user layer (namely, the attribute field of the message expected to be received by the user), and if the configured linked list rule is inquired, the successful matching is indicated. For example, if the address field contained in the linked list rule issued by the dest_mac user is identical to the dest_mac address field extracted from the received message, the matching is successful. And grouping the successfully matched messages according to the message group of the data link layer protocol, and adding configuration information based on a 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 the standard TCP/IP,

on the basis of S121-S123, confirm the goal message according to the type of the first message, including: and adding tag information into the second message to generate a target message under the condition that the type of the first message is a message of a transport layer protocol. 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.

Further, a hook function is called to analyze the second message, and tag information is determined.

In this implementation manner, considering that the message types of the transport layer protocol occupy a majority, by deleting the tag information from the first message and then performing the link rule matching, the message that the user needs to upload can be accurately identified as the message of the transport layer protocol or the message of the transport layer protocol of the network layer standard. The method solves the problem that the existing integrated equipment cannot identify whether the received message is a message of a transmission layer protocol or a message of a data link layer protocol. So as to realize the accurate shunting processing of the message under the corresponding type through the type of the message.

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

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

Specifically, a user layer provided by a character device driver adds a required linked list rule, 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 driver executes recv receiving messages through the socket, acquiring the first message, determining the label information of the first message and storing the label information. And then deleting the label information in the first message to generate a second message. Matching the linked list rule with the second message, and determining that the second message contains data corresponding to linked list elements in the linked list rule, and then successful matching. 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 type of the message of the data link layer protocol, which needs to be transmitted. And then transmitting the target message to the user layer through the protocol stack.

The format of the first packet including the tag information is shown in fig. 10, and the first packet includes tag information with a length of 6 bytes, a preamble with a length of 7 bytes, a revealing delimiter with a length of 1 byte, a source mac address with a length of 6 bytes, a destination mac address with a length of 6 bytes, a length/type with a length of 2 bytes, user data with a length of 4 bytes, a PAD with a length of 4 bytes, and a frame check sequence FSC with a length of 4 bytes. It should be noted that the data specifically included in the tag information of 6 bytes may refer to the above, and will not be described herein.

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

Illustratively, the control message protocol (Internet control message protocol, ICMP) Internet link ping packet needs to be received. The communication device sends a request message (i.e., a first message) of the internet group management protocol (Internet Group Management Protocol, IGMP), and the request message is received by the switch chip and forwarded to the network card according to the hardware connection relationship shown in fig. 2. At this time, the hook function is called by the network card, and the physical layer tag is stripped (i.e. tag information is deleted, and the tag information is different from manufacturer to manufacturer and can be determined by the respective data manual, which is not described in detail), so that the message is integrated into a 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 if the matching fails, determining the type of the second message as the message of the transport layer protocol. And uploading the second message to a network layer of the protocol stack, and receiving the second message by the network layer of the protocol stack, replying a response message, thereby realizing the process of link ping.

The matching failure condition may be that the user does not generate a 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 cannot correspond to the data in the second message. If the filled message type=0x8899 is inconsistent with the actual type 0x0800 of the received message, the protocol stack is reported 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, so that accurate transmission of the target message is realized.

In one implementation, before receiving a first message from a communication device, the method includes: receiving debugging parameters input by a user; the debugging parameters are used for indicating the message which is received and transmitted by the grabbing MAC layer; after receiving the first message from the communication device, the method includes: and grabbing the first message and the target message based on the debugging parameters. And determining the difference between the first message and the target message.

It should be noted that, the description of the present implementation refers to the description corresponding to fig. 7, and is not repeated here.

According to the implementation mode, the message received by the mac layer and the transmitted message are grabbed through the preset adjustment parameters, so that the information change condition of the front message and the rear message is determined through comparison of the front message and the rear message.

The method may divide the function modules of the resource allocation device according to the embodiment of the method, for example, each function module may be divided corresponding to each function, or two or more functions may be integrated into one processing module. The integrated modules may be implemented in hardware or in software functional modules.
