Description

Technical Field

[0001] Embodiments of the present disclosure relate to the field of computer technologies, and more particularly, to a method, apparatus, device, readable medium, and computer program product for packet forwarding. Background Art

[0002] When performing three-layer forwarding on a packet, it is usually necessary to determine whether the destination forwarding address in the packet is the same as the forwarding address of a three-layer interface (a three-layer physical port). How to store the forwarding address of the three-layer interface has become an important research topic. Currently, when storing the forwarding address of the three-layer interface, the commonly used method is to use a ternary content addressable memory (TCAM) to store the forwarding address of the three-layer interface.

[0003] However, when storing the forwarding address of the three-layer interface in the above manner, the following technical problems often exist:

[0004] First, when using a ternary content addressable memory to store a large number of addresses, it may cause insufficient storage space in the memory. When storing the same address, different editing tables may be used for storage, wasting the storage resources of the memory and reducing the utilization rate of the storage space.

[0005] Second, when forwarding a packet, it is necessary to replace the source forwarding address in the packet with the forwarding address of the corresponding three-layer interface in the outgoing address table. When there are a large number of forwarding addresses stored in the outgoing address table, it may cause insufficient storage space, and when adding a new three-layer interface, it is impossible to store the forwarding address corresponding to the new three-layer interface. Summary of the Invention

[0006] This section of the present disclosure is used to briefly introduce concepts, which will be described in detail in the following detailed implementation section. This section of the present disclosure is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0007] Some embodiments of the present disclosure provide a method, apparatus, electronic device, computer-readable medium, and computer program product for packet forwarding to solve the technical problems mentioned in the above background art section.

[0008] In a first aspect, some embodiments of the present disclosure provide a method for packet forwarding, the method including: receiving a packet to be forwarded; performing parsing processing on the packet to be forwarded to generate parsing information; in response to the parsing information satisfying a first preset condition, determining a routing forwarding address according to a first configuration value; and performing forwarding processing on the packet to be forwarded according to the parsing information and the routing forwarding address.

[0009] In a second aspect, some embodiments of the present disclosure provide a message forwarding device, the device including: a receiving unit configured to receive a message to be forwarded; a parsing and processing unit configured to parse and process the message to be forwarded to generate parsing information; a determining unit configured to, in response to the parsing information satisfying a first preset condition, determine a routing and forwarding address according to a first configuration value; and a forwarding unit configured to perform a forwarding process on the message to be forwarded according to the parsing information and the routing and forwarding address.

[0010] In a third aspect, some embodiments of the present disclosure provide an electronic device, including: one or more processors; a storage device having stored thereon one or more programs, which when executed by the one or more processors cause the one or more processors to implement the method described in any implementation manner of the first aspect above.

[0011] In a fourth aspect, some embodiments of the present disclosure provide a computer-readable medium having stored thereon a computer program, wherein the program, when executed by a processor, implements the method described in any implementation manner of the first aspect above.

[0012] In a fifth aspect, some embodiments of the present disclosure provide a computer program product, including a computer program, which when executed by a processor, implements the method described in any implementation manner of the first aspect above.

[0013] The above-mentioned various embodiments of the present disclosure have the following beneficial effects: Through the packet forwarding method of some embodiments of the present disclosure, the waste of storage resources of the memory is avoided, and the utilization rate of the storage space is improved. Specifically, the reasons for wasting the storage resources of the memory and reducing the utilization rate of the storage space are as follows: When using a ternary content addressable memory to store a large number of addresses, it may lead to insufficient storage space of the memory. When storing the same address, different editing tables are used for storage, wasting the storage resources of the memory and reducing the utilization rate of the storage space. Based on this, in the packet forwarding method of some embodiments of the present disclosure, first, a packet to be forwarded is received; the packet to be forwarded is parsed to generate parsing information. Thus, it can be determined whether the three-layer forwarding interface is valid, and when the three-layer forwarding interface is valid, the routing forwarding address is determined. Then, in response to the parsing information satisfying a first preset condition, according to a first configuration value, the routing forwarding address is determined. Thus, the routing forwarding address can be determined by a pre-configured value, without storing all existing routing forwarding addresses, avoiding the waste of storage resources of the memory and improving the utilization rate of the storage space. Finally, according to the parsing information and the routing forwarding address, the packet to be forwarded is forwarded. Thus, the source forwarding address of the report can be replaced by another pre-configured value, without storing all existing source forwarding addresses. Avoiding the waste of storage resources of the memory and improving the utilization rate of the storage space. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present disclosure will be described in detail below with reference to the drawings and in combination with embodiments.

[0026] Figure 1 It is a schematic diagram of an application scenario of a data transmission method according to some embodiments of the present disclosure.

[0027] In Figure 1 the application scenario, first, the computing device 101 can receive the packet to be forwarded 102.

Finally, the computing device 101 can perform forwarding processing on the above-mentioned packet to be forwarded 102 according to the above-mentioned parsing information 103 and the above-mentioned routing forwarding address 106.

[0028] It should be noted that the above computing device 101 can be hardware or software. When the computing device is hardware, it can be implemented as a distributed cluster composed of multiple servers or terminal devices, or as a single server or a single terminal device. When the computing device is embodied as software, it can be installed in the above-listed hardware devices. It can be implemented as, for example, multiple software or software modules for providing distributed services, or as a single software or software module. No specific limitation is made here.

[0029] It should be understood that Figure 1 the number of computing devices in [] is merely illustrative. According to the implementation requirements, there can be any number of computing devices.

[0030] Figure 2 The flowchart 200 of some embodiments of the message forwarding method according to the present disclosure is shown. The message forwarding method includes the following steps:

[0031] Step 201, receiving the message to be forwarded.

[0032] In some embodiments, the execution subject (such as a server) of the message forwarding method can receive the message to be forwarded sent by the associated terminal device through a wired connection or a wireless connection. Among them, the above message to be forwarded can be a message that needs to be forwarded.

[0033] Step 202, parsing and processing the message to be forwarded to generate parsing information.

[0034] In some embodiments, the above execution subject can parse and process the above message to be forwarded to generate parsing information. Among them, the above parsing process can be to determine each field included in the message to be forwarded as parsing information.

[0035] Optionally, after step 202, in response to the parsing information not meeting the first preset condition, perform layer 2 forwarding processing on the above message to be forwarded.

[0036] In some embodiments, the execution entity may perform layer-2 forwarding processing on the to-be-forwarded packet in response to the parsing information not satisfying the first preset condition. In practice, in response to the parsing information not satisfying the first preset condition, the execution entity may perform layer-2 forwarding processing on the to-be-forwarded packet according to the layer-2 forwarding table stored in the switching chip. Among them, the above layer-2 forwarding processing may be to forward the to-be-forwarded packet out of the switching chip in a layer-2 forwarding manner. The above first preset condition may be that the layer-3 forwarding interface included in the execution entity is valid. The above layer-3 forwarding interface may be a layer-3 Ethernet interface. Here, the execution entity may determine whether the layer-3 forwarding interface is valid according to the field representing the virtual local area network in the parsing information. As an example, in response to the field value of the field representing the virtual local area network being 0xffff, it may indicate that the layer-3 interface is invalid. In response to the field value of the field representing the virtual local area network being 0 to 0xfffe, it may indicate that the layer-3 interface is valid.

[0037] Step 203, in response to the parsing information satisfying the first preset condition, determine the routing forwarding address according to the first configuration value.

[0038] In some embodiments, the execution entity may determine the routing forwarding address according to the first configuration value in response to the parsing information satisfying the first preset condition. Among them, the above first configuration value may be a preset value. For example, the above first configuration value may be 0.

[0039] In practice, the execution entity may determine the routing forwarding address through the following steps:

[0040] The first step, in response to the first configuration value being the same as the first preset value, obtain the global routing forwarding address and determine the global routing forwarding address as the routing forwarding address. Among them, the above first preset value may be a preset value representing that the routing forwarding address is the global routing forwarding address. The above global routing forwarding address may be a pre-set basic MAC (Media Access Control Address) address.

[0041] The second step, in response to the first configuration value being the same as the second preset value, obtain the global routing forwarding address and the forwarding interface code. Among them, the above second preset value may be another preset value. The above forwarding interface code may be the code of the layer-3 physical port of the switching chip. The above code may uniquely represent a certain layer-3 physical port.

[0042] Step 3: Combine the above global routing forwarding address and the above forwarding interface code for processing to generate a first combined address as the routing forwarding address. In practice, first, the above execution entity can perform a base conversion process on the forwarding interface code to generate a converted forwarding interface code. Second, the above execution entity can perform a conversion process on the converted forwarding interface code and the above global routing forwarding address to generate a first combined address as the routing forwarding address. Among them, the above combination process can be a merging process. The above base conversion process can be converting a decimal number to a hexadecimal number.

[0043] As an example, the above forwarding interface code can be 10. The above global routing forwarding address can be MAC[48:12]=0x0200c18a1. At this time, the global routing forwarding address can be the high-order MAC address, and "0x" indicates that the characters after "0x" are hexadecimal numbers. Thus, it can be known that the forwarding interface code is the low-order 12-bit address of the MAC address. First, the above forwarding interface code "10" can be subjected to a base conversion process to generate a converted forwarding interface code "a". Among them, the above base conversion process can be converting a decimal number to a hexadecimal number. Second, the above global routing forwarding address "0x0200c18a1" and the above converted forwarding interface code "a" can be combined for processing to generate a first combined address as the routing forwarding address. Here, since the forwarding interface code is the low-order 12-bit address of the MAC, and the converted forwarding interface code "a" is 4 bits, thus, "00" needs to be added before the converted forwarding interface code "a" to reach 12 bits, thereby generating a first combined address "0x0200c18a100a" as the routing forwarding address.

[0044] Step 4: In response to the above first configuration value being the same as the third preset value, obtain the virtual local area network code and the global routing forwarding address. Among them, the above virtual local area network code can uniquely represent a certain virtual local area network port. The above first preset value, second preset value, and third preset value are different.

[0045] Step 5: Combine the above global routing forwarding address and the above virtual local area network code for processing to generate a second combined address as the routing forwarding address.

[0046] Step 204: Forward the packet to be forwarded according to the parsing information and the routing forwarding address.

[0047] In some embodiments, the above-mentioned execution entity may forward the to-be-forwarded packet according to the above-mentioned parsing information and the above-mentioned routing forwarding address. In practice, first, the above-mentioned execution entity may, in response to the field value of the field representing the destination forwarding address included in the above-mentioned parsing information being the same as the above-mentioned routing forwarding address, replace the field value of the field representing the source forwarding address included in the above-mentioned to-be-forwarded packet with the above-mentioned routing forwarding address. Second, the destination forwarding address corresponding to the above-mentioned to-be-forwarded packet may be determined through the ARP protocol (Address Resolution Protocol). Third, the above-mentioned to-be-forwarded packet is forwarded to the network device corresponding to the above-mentioned destination forwarding address. Among them, the above-mentioned network device may be a terminal device with network functions. For example, the above-mentioned network device may include, but is not limited to, one of the following: mobile phone, computer.

[0048] The above-mentioned various embodiments of the present disclosure have the following beneficial effects: Through the packet forwarding method of some embodiments of the present disclosure, the waste of storage resources of the memory is avoided, and the utilization rate of the storage space is improved. Specifically, the reasons for wasting the storage resources of the memory and reducing the utilization rate of the storage space are as follows: When using a ternary content addressable memory to store a large number of addresses, it may cause the storage space of the memory to be insufficient, and different editing tables will be used to store the same address, wasting the storage resources of the memory and reducing the utilization rate of the storage space. Based on this, in the packet forwarding method of some embodiments of the present disclosure, first, a to-be-forwarded packet is received; the above-mentioned to-be-forwarded packet is parsed to generate parsing information. Thus, it can be determined whether the three-layer forwarding interface is valid, and the routing forwarding address is determined when the three-layer forwarding interface is valid. Then, in response to the above-mentioned parsing information satisfying the first preset condition, the routing forwarding address is determined according to the first configuration value. Thus, the routing forwarding address can be determined through the pre-configured value, without storing all existing routing forwarding addresses, avoiding the waste of storage resources of the memory and improving the utilization rate of the storage space. Finally, the above-mentioned to-be-forwarded packet is forwarded according to the above-mentioned parsing information and the above-mentioned routing forwarding address. Thus, the source forwarding address of the report can be replaced by another pre-configured value, without storing all existing source forwarding addresses. Avoid the waste of storage resources of the memory and improve the utilization rate of the storage space.

[0049] Further referring to Figure 3 , a flowchart 300 showing another embodiment of the packet forwarding method according to the present disclosure is shown. The packet forwarding method includes the following steps:

[0050] Step 301, receive a to-be-forwarded packet.

[0051] Step 302, parse the to-be-forwarded packet to generate parsing information.

[0052] Step 303: In response to the parsing information satisfying the first preset condition, determine the routing forwarding address according to the first configuration value.

[0053] In some embodiments, the specific implementation manners and the technical effects brought by steps 301-303 may refer to steps 201-203 in the corresponding embodiments, which will not be elaborated herein. Figure 2 The corresponding steps 201-203 in those embodiments will not be elaborated herein.

[0054] Step 304: In response to the above parsing information and the above routing forwarding address satisfying the second preset condition, modify the above packet to be forwarded according to the second configuration value to generate a modified packet.

[0055] In some embodiments, the above execution entity may, in response to the above parsing information and the above routing forwarding address satisfying the second preset condition, modify the above packet to be forwarded according to the second configuration value to generate a modified packet. Among them, the above second preset condition may be that the field value of the field representing the routing forwarding address in the above parsing information is the same as the above routing forwarding address. The above second configuration value may be another preset value.

[0056] In practice, the above execution entity may modify the above packet to be forwarded through the following steps to generate a modified packet:

[0057] First step: In response to the above second configuration value being the same as the above first preset value, replace the field value of the field representing the source forwarding address (source MAC address) in the above packet to be forwarded with the above global routing forwarding address to modify the above packet to be forwarded and obtain a modified packet.

[0058] Second step: In response to the above second configuration value being the same as the above second preset value, replace the field value of the field representing the source forwarding address in the above packet to be forwarded with the above first combined address to modify the above packet to be forwarded and obtain a modified packet.

[0059] Third step: In response to the above second configuration value being the same as the above third preset value, replace the field value of the field representing the source forwarding address in the above packet to be forwarded with the above second combined address to modify the above packet to be forwarded and obtain a modified packet.

[0060] Step 305: Forward the above modified packet.

[0061] In some embodiments, the above execution entity may forward the above modified packet. Among them, the above forwarding process may be a three-layer forwarding process.

[0062] Optionally, after step 305, in response to the above parsing information and the above routing forwarding address not satisfying the above second preset condition, perform layer-2 forwarding processing on the above to-be-forwarded message.

[0063] In some embodiments, the above execution subject may, in response to the above parsing information and the above routing forwarding address not satisfying the above second preset condition, perform layer-2 forwarding processing on the above to-be-forwarded message.

[0064] The relevant content in the above steps 304-305 is an inventive point of the present disclosure, which solves the second technical problem mentioned in the background art: "When forwarding a message, it is necessary to replace the source forwarding address in the message with the forwarding-out address of the corresponding layer-3 interface in the forwarding-out address table. When there are many forwarding-out addresses stored in the forwarding-out address table, it may cause insufficient storage space, and when adding a new layer-3 interface, it is impossible to store the forwarding-out address corresponding to the new layer-3 interface." The factors causing insufficient storage space and being unable to store the forwarding-out address corresponding to the new layer-3 interface are usually as follows: When forwarding a message, it is necessary to replace the source forwarding address in the message with the forwarding-out address of the corresponding layer-3 interface in the forwarding-out address table. When there are many forwarding-out addresses stored in the forwarding-out address table, it may cause insufficient storage space, and when adding a new layer-3 interface, it is impossible to store the forwarding-out address corresponding to the new layer-3 interface. If the above factors are solved, the effect of avoiding insufficient storage space and being able to store the forwarding-out address corresponding to the new layer-3 interface can be achieved. To achieve this effect, first, in response to the above parsing information and the above routing forwarding address satisfying the second preset condition, modify the above to-be-forwarded message according to the second configuration value to generate a modified message. Thus, each forwarding-out address in the forwarding-out address table can be generated through the encoding of the layer-3 interface and the global routing address, which can reduce the number of bytes stored, thereby avoiding insufficient storage space and being able to store the forwarding-out address corresponding to the new layer-3 interface. Second, perform forwarding processing on the above modified message. Thus, the storage of each forwarding-out address in the forwarding-out address table is completed, avoiding insufficient storage space and being able to store the forwarding-out address corresponding to the new layer-3 interface.

[0065] From Figure 3 it can be seen that compared with Figure 2 the description of some corresponding embodiments, Figure 3 the process 300 of the message forwarding method in some corresponding embodiments avoids insufficient storage space and can store the forwarding-out address corresponding to the new layer-3 interface.

[0066] Further referring to Figure 4 , as an implementation of the methods shown in the above figures, the present disclosure provides some embodiments of a message forwarding device.
