Technical Field

[0001] This application relates to the field of network communication technology, and more specifically, to a message processing method, apparatus, electronic device, and non-volatile storage medium. Background Technology

[0002] With the widespread application of Segment Routing IPv6 Traffic Engineering (SRv6 TE) technology based on Internet Protocol version 6, higher demands are placed on the packet editing capabilities of Application Specific Integrated Circuit (ASIC) chips. In SRv6 TE tunnel scenarios, when it is necessary to edit certain special packets in the inner layer of the tunnel, such as Operations, Administration, and Maintenance (OAM) packets, the relevant technology involves the downlink pipeline of the ASIC chip to perform OMA packet editing and tunnel header addition operations. Due to the excessive length of the header and the insufficient downlink editing capability of the chip, there is a possibility that the chip may not be able to provide editing capabilities or that additional pipeline detours may be required for editing, which may lead to the problem of OAM packet errors and packet loss.

[0010] Optionally, in the downlink pipeline stage, the processing flow for the modified target message of type operation management and maintenance message is the same as the processing flow for the target message of type non-operation management and maintenance message.

[0011] Optionally, adding a tunnel encapsulation header to the modified target message includes: generating a tunnel encapsulation header corresponding to the tunnel encapsulation information based on the tunnel encapsulation information; encapsulating the tunnel encapsulation header into the modified target message; and sending the encapsulated target message to the corresponding address.

[0012] According to another aspect of the embodiments of this application, a message processing apparatus is also provided, comprising: an encapsulation information determination module, configured to determine tunnel encapsulation information corresponding to a target message during the uplink pipeline stage of a target chip, wherein the tunnel encapsulation information is used to indicate the path of the virtual private network tunnel required to send the target message to the destination address, and the uplink pipeline is the process of the target chip receiving messages; and a message modification module, configured to parse the target message to obtain message modification information corresponding to the target message when the type of the target message is an operation, management and maintenance message, and modify the target message according to the message modification information; and an encapsulation sending module, configured to send the modified target message to the downlink pipeline of the target chip, and add a tunnel encapsulation header to the modified target message during the downlink pipeline stage according to the tunnel encapsulation information, wherein the downlink pipeline is the process of the target chip sending messages.

Figure 2 As shown, in related technologies, the characteristics of ASIC pipelines are manifested as upward table lookup and downward editing.

[0026] However, the editing capabilities of ASIC chips are often limited. In SRv6 TE VPN scenarios, there may be situations where the excessive length of the encapsulation header causes the chip's editing capabilities to approach their limit when editing packets. In such cases, for OAM packets carried in the inner layer of the VPN tunnel, the downlink editing module of the ASIC chip, after modifying the OAM packets, cannot continue to add tunnel encapsulation to the OAM packets because it has reached its editing capability limit, thus preventing the OAM packets from being forwarded correctly.

[0027] To address the aforementioned issues, this application provides relevant solutions, which are detailed below.

[0028] According to an embodiment of this application, a method embodiment for message processing is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

Figure 1 As shown, the computer terminal 10 (or electronic device) may include one or more processors 102 (shown as 102a, 102b, ..., 102n in the figure) 102 (processor 102 may include, but is not limited to, a microprocessor MCU or a programmable logic device FPGA, etc.), a memory 104 for storing data, and a transmission device 106 for communication functions. In addition, it may also include: a display, an input / output interface (I / O interface), a universal serial bus (USB) port (which may be included as one of the ports of a BUS bus), a network interface, a power supply, and / or a camera.

For example, computer terminal 10 may also include... Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown.

[0030] It should be noted that the aforementioned one or more processors 102 and / or other data processing circuits are generally referred to herein as "data processing circuits". These data processing circuits may be embodied, in whole or in part, in software, hardware, firmware, or any other combination thereof. Furthermore, the data processing circuits may be a single, independent processing module, or may be integrated, in whole or in part, into any other element within the computer terminal 10 (or electronic device). As involved in the embodiments of this application, the data processing circuits serve as a processor control mechanism (e.g., selection of a variable resistor termination path connected to an interface).

[0031] The memory 104 can be used to store software programs and modules of application software, such as the program instructions / data storage device corresponding to the message processing method in the embodiments of this application.

[0033] The display may be, for example, a touchscreen liquid crystal display (LCD) that allows the user to interact with the user interface of the computer terminal 10 (or electronic device).

[0034] Under the aforementioned operating environment, this application provides a message processing method to address the shortcomings of ASIC chips in SRv6 TE VPN scenarios, which lead to excessively deep inner message editing and consequently, outbound OAM message editing defects. Figure 3 This is a schematic diagram of a message processing method according to an embodiment of this application, such as... Figure 3 As shown, the method includes the following steps:

[0035] Step S302: In the uplink pipeline stage of the target chip, the tunnel encapsulation information corresponding to the target message is determined. The tunnel encapsulation information is used to indicate the path of the virtual private network tunnel that needs to be traversed to send the target message to the destination address. The uplink pipeline is the process of the target chip receiving the message.

[0036] Step S304: If the target message is an operation management and maintenance message, parse the target message to obtain the message modification information corresponding to the target message, and modify the target message according to the message modification information;

[0037] Step S306: The modified target message is sent to the downlink pipeline of the target chip. In the downlink pipeline stage, a tunnel encapsulation header is added to the modified target message according to the tunnel encapsulation information. The downlink pipeline is the process of the target chip sending messages.

[0038] Through the above steps, by modifying the existing ASIC chip pipeline uplink architecture and increasing the uplink editing and processing capabilities of messages, the correct forwarding of OAM messages is achieved. This solves the problem of packet loss due to insufficient downlink editing capabilities caused by excessively long headers when editing operation, management, and maintenance messages in related technologies. It provides a basis for Ethernet link status in SRv6 TE VPN scenarios and offers complete reference indicators for improving the quality of network services for operators.

[0039] The following describes the message processing method in steps S302 to S306 of this application embodiment, taking an ASIC chip as the target chip.

[0040] Figure 4 This is a schematic diagram of a method flow for OAM message processing of an ASIC chip according to an embodiment of this application, as shown below. Figure 4 As shown, in this application, an uplink editing module is added to the uplink pipeline of the ASIC chip (target chip) for uplink editing of special messages (e.g., target messages of type Operation Management and Maintenance (OAM) messages). Compared with the uplink lookup and downlink editing mode of the ASIC pipeline in related technologies, this application solves the problem of insufficient downlink editing capability of ASIC chips in the SRv6 TEVPN scenario by modifying the fields of the OAM message according to the uplink lookup result after the uplink lookup behavior through the added uplink editing module.

[0041] The following section details the process steps for handling Operation Management and Maintenance (OAM) messages and ordinary messages (i.e., the aforementioned non-Operation Management and Maintenance messages) in the improved ASIC chip pipeline.

[0042] First, when the target packet passes through the uplink pipeline stage of the ASIC chip, the tunnel encapsulation information corresponding to the target packet is determined. The tunnel encapsulation information is used to indicate the path of the virtual private network tunnel that needs to be traversed to send the target packet to the destination address. The uplink pipeline is the process of the target chip receiving the packet.

[0043] In this embodiment, the tunnel encapsulation information of the target packet's outgoing SRv6TEVPN tunnel can be obtained through the uplink lookup table module in the chip. The specific steps are as follows.

[0044] In some embodiments of this application, determining the tunnel encapsulation information corresponding to the target packet includes the following steps: determining the source address and destination address corresponding to the target packet; performing a table lookup based on the source address and destination address to determine the virtual private network tunnel that matches the source address and destination address; and generating tunnel encapsulation information based on the parameter information of the virtual private network tunnel.

[0045] In the above steps, regardless of whether the target message is a special operation management and maintenance message or a normal non-operation management and maintenance message, the process steps for determining the tunnel encapsulation information are the same. After determining the tunnel encapsulation information, it is necessary to perform uplink editing processing on the target message of type operation management and maintenance message. That is, the target message of type operation management and maintenance message is parsed to obtain the message modification information corresponding to the target message, and the target message is modified according to the message modification information. The uplink editing process will be further explained below.

[0046] Specifically, after determining the tunnel encapsulation information corresponding to the target packet, the type of the target packet is first determined based on the Ethernet type field of the target packet to determine whether the target packet is an Operation, Administration and Maintenance (OAM) packet. The specific steps are as follows.

[0047] In some embodiments of this application, before parsing the target message, the method further includes the following steps: obtaining the Ethernet type field in the target message, wherein the Ethernet type field is used to characterize the upper-layer protocol type corresponding to the target message; if the Ethernet type field is consistent with a preset field, the target message is determined to be an operation, management and maintenance message.

[0048] If the target message is not an operation management and maintenance message type, then no editing operation is required on the message during the uplink editing process. If the target message is an operation management and maintenance message type, then the editing information of the OAM message is obtained by parsing the inner fields of the target message (OAM message). The specific steps are as follows.

[0049] In some embodiments of this application, parsing the target message to obtain the message modification information corresponding to the target message includes the following steps: determining the position and length of each field in the target message according to the protocol specification corresponding to the operation management and maintenance message; extracting the value of each field in the target message according to the position and length of the field; parsing according to the meaning of the field and the extracted value of the field to obtain the message modification information corresponding to the target message, wherein the message modification information includes: the type of modification operation, the modification position, and the modification value.

[0050] After obtaining the message modification information corresponding to the target message, before the target message (OAM message) leaves the uplink pipeline, the uplink editing module of the target chip (ASIC chip) will also edit the target message (OAM message) as needed based on the message modification information. The specific steps are as follows.

[0051] In some embodiments of this application, modifying a target message based on message modification information includes the following steps: In the uplink pipeline stage, the uplink editing module in the target chip controls the corresponding modification operation of the fields at the modification position in the target message based on the message modification information to obtain the modified target message. The structure of the modified target message of type operation management and maintenance message is the same as that of the target message of type non-operation management and maintenance message, both of which only include: message content and tunnel encapsulation information.

[0052] After the uplink editing process described above, for the same SRv6 TE VPN tunnel, the modified target packet (the OAM packet modified by the uplink editing module) and the target packet of type non-operation management and maintenance (ordinary packet) have the same tunnel encapsulation information in the downlink editing module of the downlink pipeline. That is, in the downlink pipeline stage, the processing flow for the modified target packet of type operation management and maintenance is the same as that for the target packet of type non-operation management and maintenance, and the two have completely unified editing behavior in the downlink editing module. Through uplink packet editing, the downlink encapsulation of OAM packets in the SRv6 TE VPN scenario remains consistent with that of ordinary packets, avoiding OAM packet error dropping or additional roundabout editing caused by insufficient downlink editing capabilities.

[0053] Specifically, both the modified target message (the OAM message modified by the uplink editing module) and the target message of type non-operation management and maintenance message (ordinary message) need to be encapsulated with an SRv6 TEVPN tunnel header in the downlink pipeline stage of the target chip. That is, for the same SRv6 TE VPN tunnel, both the modified target message of type operation management and maintenance message and the target message of type non-operation management and maintenance message are uniformly encapsulated in the downlink editing module according to the SRv6 TE VPN tunnel encapsulation information obtained from the uplink lookup table. The specific steps are as follows.

[0054] In some embodiments of this application, adding a tunnel encapsulation header to the modified target message includes the following steps: generating a tunnel encapsulation header corresponding to the tunnel encapsulation information based on the tunnel encapsulation information; encapsulating the tunnel encapsulation header into the modified target message; and sending the encapsulated target message to the corresponding address.

[0055] This application adds an uplink editing module to the ASIC chip pipeline. By editing special service messages such as OAM uplink, the editing capability of the ASIC chip is improved, making the downlink outgoing chip packaging in the SRv6 TE VPN scenario consistent with the ordinary message packaging. This solves the problem that the existing solution cannot properly edit the inner OAM and other special messages in the SRv6 TE VPN tunnel encapsulation scenario.

[0056] According to an embodiment of this application, an embodiment of a message processing apparatus is also provided. Figure 5 This is a schematic diagram of a message processing apparatus according to an embodiment of this application. Figure 5 As shown, the device includes:

The uplink pipeline is the process of the target chip receiving the message.

[0058] In some embodiments of this application, determining the tunnel encapsulation information corresponding to the target packet includes: determining the source address and destination address corresponding to the target packet; performing a table lookup based on the source address and destination address to determine the virtual private network tunnel that matches the source address and destination address; and generating tunnel encapsulation information based on the parameter information of the virtual private network tunnel.

[0059] The message modification module 52 is used to parse the target message when the target message type is an operation management and maintenance message, obtain the message modification information corresponding to the target message, and modify the target message according to the message modification information;

[0060] In some embodiments of this application, before parsing the target message, the message modification module 52 is further configured to: obtain the Ethernet type field in the target message, wherein the Ethernet type field is used to characterize the upper-layer protocol type corresponding to the target message; and determine that the target message is an operation management and maintenance message if the Ethernet type field is consistent with the preset field.

[0062] In some embodiments of this application, the message modification information includes: the type of modification operation, the modification location, and the modification value; modifying the target message according to the message modification information includes: in the uplink pipeline stage, controlling the uplink editing module in the target chip to perform corresponding modification operations on the fields at the modification location in the target message according to the message modification information to obtain the modified target message. The structure of the modified target message of type operation management and maintenance message is the same as that of the target message of type non-operation management and maintenance message, both including only: message content and tunnel encapsulation information.

[0063] In some embodiments of this application, during the downlink pipeline stage, the processing flow for the modified target message of type operation management and maintenance message is the same as the processing flow for the target message of type non-operation management and maintenance message.

[0064] The encapsulation and transmission module 54 is used to send the modified target message to the downlink pipeline of the target chip. In the downlink pipeline stage, a tunnel encapsulation header is added to the modified target message according to the tunnel encapsulation information. The downlink pipeline is the process of the target chip sending messages.

[0065] In some embodiments of this application, adding a tunnel encapsulation header to the modified target message includes: generating a tunnel encapsulation header corresponding to the tunnel encapsulation information based on the tunnel encapsulation information; encapsulating the tunnel encapsulation header into the modified target message; and sending the encapsulated target message to the corresponding address.
