DETAILED DESCRIPTION

[0013] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.
[0014] Currently, for network communication devices, the number of MAC addresses integrated into commonly used CPUs or the number of additional MAC addresses supported is often limited. When faced with scenarios where a large amount of data needs to be processed simultaneously, some network communication devices need to be equipped with multiple network card interfaces to ensure smooth data communication. However, from the perspective of hardware cost, adding multiple network card interfaces for receiving and sending messages increases communication costs.
[0015] In view of this, an embodiment of the present application provides a method for expanding a network card device based on a switch chip, in which a first message is obtained, a first port of the first message is determined, and a label corresponding to the first port is found, a first target label is added to the first message, and a second message is obtained, and then the second message is transmitted to a switching device through a physical interface, the switching device identifies the first target label in the second message, and determines the first target port corresponding to the first target label in the second message according to a first correspondence between a pre-configured reference label and a reference port, and then strips off the first target label in the second message to obtain the first message, and forwards the first message through the first target port. It can be seen that the present application increases the number of MACs by expanding the network card interface in a software-coordinated manner, realizes parallel processing of multiple data, and thus reduces costs. In order to make the technical solution of the present application clearer and easier to understand, the application scenarios of the technical solution of the present application are introduced below in conjunction with the accompanying drawings. Figure 1 As shown, the figure is a schematic diagram of an application scenario provided by an embodiment of the present application.
[0016] In this application scenario, the CPU transmits messages to the switch through MAC0. The CPU includes 8 ports, namely G1, G2, G3, G4, G5, G6, G7 and G8. The messages in the CPU are transmitted through different ports, and the target VID tag is added to the message according to the port through which the message passes, and then transmitted to the switch.
[0017] The switch transmits messages with the CPU through a physical interface EXT0. The switch includes 8 output ports, namely UTP0, UTP1, UTP2, UTP3, UTP4, UTP5, UTP6 and UTP7. The switch will receive the message with the target VID label, identify the message, determine the output port corresponding to the message with the target VID label, then strip the target VID label on the message, and then forward it from the corresponding output port.
[0018] To this end, the CPU can transmit multiple messages from different ports to the switch, and then forward the multiple messages through the output port in the switch to achieve multiple data parallel processing. It can be seen that this application increases the number of MACs by expanding the network card interface in a software-coordinated manner, achieves multiple data parallel processing, and thus reduces costs.
[0019] In order to make the technical solution of the present application clearer and easier to understand, the following describes a method for expanding a network card device based on a switch chip provided by an embodiment of the present application in combination with the above application scenario. Figure 2 As shown in FIG. 1 , the figure is a flow chart of a method for expanding a network card device based on a switch chip provided in an embodiment of the present application. The method for expanding a network card device based on a switch chip includes: S201. Obtain a first message.
[0020] The central processing unit (CPU) is the computing and control core of the computer system and the final execution unit for information processing and program running. The CPU obtains the first message from the memory and transmits the first message to the switch through one of the CPU ports.
[0021] Among them, the CPU contains 8 ports, including G1, G2, G3, G4, G5, G6, G7 and G8, and the corresponding labels are 2, 3, 4, 5, 6, 7, 8 and 9 respectively.
[0022] In the embodiment of the present application, the tag refers to the VLAN ID, which is the abbreviation of Virtual Local Area Network Identifier, and is a digital identifier used to uniquely identify a VLAN (virtual local area network). The VLAN ID is an integer between 1 and 4094, used to distinguish different virtual local area networks. The tag protocol identifier of the tag is 0x8100.
[0023] In the embodiment of the present application, it is assumed that the first message is transmitted from the port G1.
[0024] S202: Determine a first port of the first message, and find a label corresponding to the first port, and name it as a first target label.
[0025] In the present application, it is determined that the port of the first message is G1, G1 is named as the first port, and it is found that the VID label corresponding to the first port G1 is 2.
[0026] S203: Add the first target label to the first message to obtain a second message.
[0027] In the present application, the first target label is 2, so the first message is marked with the first target label 2 to obtain the second message.
[0028] S204: Transmit the second message to the switching device through the physical interface.
[0029] There is MAC0 in the CPU, and data communication is performed with the switch through MAC0. The CPU transmits the second message with the target VID tag to the switching device switch.
[0030] MAC address is a unique identifier used by network devices (such as network cards, routers, etc.) below the network layer to locate devices in the network and transmit data. MAC address plays a vital role in network communication. When data is transmitted in the network, the MAC addresses of the source device and the destination device are included in the header of the data frame to ensure that the data can be accurately sent to the destination device.
[0031] The main function of a switch is to forward and filter packets, and to quickly transfer packets from one port to another through the internal switching matrix. At the same time, a switch also has functions such as address learning, forwarding / filtering, and loop avoidance.
[0032] The switch receives and analyzes data packets, learns and records the mapping relationship between the source MAC address and the corresponding port, and establishes a MAC address table. When the switch receives a data packet, it searches the MAC address table based on the destination MAC address and determines which port the data packet is forwarded from. If the destination MAC address is not in the MAC address table, it is forwarded to all ports. This process is called flooding.
[0033] Switching devices are widely used in various network environments, such as enterprise networks, campus networks, data centers, etc. In enterprise networks, switching devices are used to connect computers, printers and other devices in various departments to achieve information sharing and communication. In campus networks, switching devices are used to connect network devices in teaching buildings, libraries and other areas to provide network services. In data centers, switching devices are used to connect servers, storage devices, etc. to build a high-performance network architecture.
[0034] S205: Identify the first target tag in the second message.
[0035] The switching device switch receives the second message, identifies and parses the data information in the second message, and obtains the target VID tag.
[0036] S206: Determine a first destination port corresponding to the first destination label in the second message according to a pre-configured first correspondence between the reference label and the reference port, and strip the first destination label in the second message to obtain a first message.
[0037] The switching device switch has a first correspondence relationship between preconfigured reference labels and reference ports, wherein the reference ports include UTP0, UTP1, UTP2, UTP3, UTP4, UTP5, UTP6 and UTP7, and the corresponding VID labels are 2, 3, 4, 5, 6, 7, 8 and 9 respectively.
[0038] In the above steps, it can be known that the first target label is 2. According to the first correspondence between the reference label and the reference port, the port corresponding to the first target label 2 is UTP0. Therefore, it is determined that the first target port corresponding to the first target label in the second message is UTP0. The switching device switch strips the first target label in the second message to obtain the first message.
[0039] S207: Forward the first message through the first target port.
[0040] In S206, it is determined that the first target port is UTP0, and the first message is forwarded through the first target port UTP0.
[0041] Based on the above content, in the present application, by obtaining the first message, determining the first port of the first message, and finding the label corresponding to the first port, the first message is marked with the first target label to obtain the second message, and then the second message is transmitted to the switching device through the physical interface, the switching device identifies the first target label in the second message, and determines the first target port corresponding to the first target label in the second message according to the first correspondence between the pre-configured reference label and the reference port, and then strips the first target label in the second message to obtain the first message, and forwards the first message through the first target port. It can be seen that the present application increases the number of MACs by expanding the network card interface in software cooperation, realizes parallel processing of multiple data, and thus reduces costs.
[0042] The embodiment of the present application also provides a method for expanding a network card device based on a switch chip, such as Figure 3 As shown, the figure is a flowchart of another method for extending a network card device based on a switch chip provided by an embodiment of the present application. The method includes: S301. Receive a third message through a second port, find a label corresponding to the second port, name it as a second target label, and add the second target label to the third message to obtain a fourth message.
[0043] In the embodiment of the present application, the second port is set to G8, and the third message is transmitted from the G8 port. According to the label 9 corresponding to the G8 output port, it can be determined that the second target label is 9.
[0044] S302: Transmit the fourth message to the CPU through the physical interface.
[0045] S303: Identify the second target tag in the fourth message.
[0046] The CPU receives the fourth message, identifies and parses the data information in the fourth message, and obtains the second target tag.
[0047] S304: Determine the target port corresponding to the second target label in the fourth message according to the pre-configured second corresponding relationship between the reference label and the reference port, and then strip the second target label in the fourth message to obtain a third message.
[0048] The CPU determines the second target port corresponding to the second target label in the fourth message based on the second correspondence between the pre-configured reference label and the reference port. In the above text, the second target label is determined to be 9, so it can be determined that the second target port is UTP7. The second target label 9 in the fourth message is stripped to obtain the third message.
[0049] S305. Forward the third message through the second target port.
[0050] The CPU forwards the third message through the second target port UTP7.
[0051] In the present application, the switching device switch obtains the third message, determines the second port of the third message, finds the label corresponding to the second port, adds the second target label to the third message, obtains the fourth message, and then transmits the fourth message to the switching device through the physical interface. The CPU identifies the second target label in the fourth message, determines the second target port corresponding to the second target label in the fourth message according to the second correspondence between the pre-configured reference label and the reference port, and then strips the second target label in the fourth message to obtain the third message, and forwards the third message through the second target port. It can be seen that the present application increases the number of MACs by expanding the network card interface in software cooperation, realizes parallel processing of multiple data, and thus reduces costs.
