Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a soft failure protection method, device, equipment and storage medium for a switching chip. Background Art

[0002] With the widespread adoption and application of the internet, various network devices (such as routers, switches, firewalls, and video security access devices) have played a significant role in people's lives and work. However, due to various reasons, network devices often fail, especially network security devices such as firewalls and access devices. Network devices have multiple service functions and complex modules, and configuration errors and other reasons often lead to network device failures, impacting user services. For example, soft failures such as cosmic rays, Boron fission, alpha radiation, system noise, and electromagnetic interference can cause network device failures.

[0003] When network equipment is located between a large number of devices or in a complex electromagnetic environment, its working status cannot be guaranteed to be 100% stable. Hardware forwarding modules such as switching chips that receive messages are prone to soft failures such as register momentary abnormalities and loss of register hardware entries, resulting in abnormal network equipment services and causing significant losses.

[0004] To address soft failures in current network equipment, the industry's typical approach is to improve electromagnetic noise tolerance by resetting boards and improving processes. However, there are no effective measures to proactively and quickly repair detected soft failures, which results in damage to the service functions of network equipment. Summary of the Invention

[0027] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0028] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0029] In related technology, when high-energy subatomic particles travel through the silicon in ultra-large-scale circuit memory cells (flip-flops, registers, or RAM cells), they generate free charges. These charges accumulate in circuit nodes within a very short time interval (approximately 15 ps). When the charge accumulation exceeds a certain level, the stored data changes, causing system errors. Because the damage to the circuit is not permanent, this phenomenon is called a soft failure.

[0030] Example 1

[0031] Figure 1 A flowchart of a soft failure protection method for a switching chip is provided for the first embodiment of the present invention. This embodiment is applicable to the case of protecting the soft failure of a switching chip. The method can be executed by a soft failure protection device of the switching chip. The soft failure protection device of the switching chip can be implemented in the form of hardware and / or software. The soft failure protection device of the switching chip can be configured in a network device, wherein the network device includes a switching chip. Figure 1 As shown, the method includes:

[0032] S110 : In response to a soft failure monitoring event being triggered, obtain first register resource information stored in the network device according to a preset period.

[0033] Network equipment is specialized hardware used to interconnect various servers, PCs, application terminals, and other nodes to form information and communication networks. Network equipment can include switches, routers, firewalls, bridges, hubs, gateways, VPN servers, network interface cards, wireless access points, modems, 5G base stations, optical terminals, fiber optic transceivers, and optical cables.

[0034] In an embodiment of the present invention, a network device includes a processor and a switching chip, and the switching chip includes one or more registers. For example, the processor may be a CN9130 processor, and the switching chip may be a 98DX336S switching chip. It should be noted that the embodiment of the present invention does not limit the models of the processor and switching chip in the network device.

[0035] Exemplarily, when a soft failure monitoring instruction input by a user is received, a soft failure monitoring event is triggered; or, when it is determined that the network device meets a preset condition, a soft failure monitoring event is triggered. It should be noted that the embodiment of the present invention does not limit the triggering conditions of the soft failure monitoring event. When the soft failure monitoring event is triggered, the first register resource information stored in the network device is obtained according to a preset period. For example, the first register resource information stored in the network device can be obtained by setting a timer task. Optionally, the first register resource information can be status information of a register in a switching chip pre-stored in the network device, or it can be service table item data dynamically stored in the network device.

[0036] S120: Read the second register resource information of the switch chip in the network device.

[0037] In an embodiment of the present invention, second register resource information of a switching chip is read from a switching chip of a network device, where the second register resource information and the first register resource information are of the same type. For example, if the first register resource information is status information of a register in the switching chip pre-stored in the network device, then the second register resource information is status information of the register in the switching chip read in real time from the switching chip. For another example, if the first register resource information is service table entry data dynamically stored in the network device, then the second register resource information is service table entry data in the switching chip read in real time from the switching chip.

[0038] S130: When the second register resource information is inconsistent with the first register resource information, send the first register resource information to the switching chip to repair the second register resource information based on the first register resource information.

[0039] In an embodiment of the present invention, the second register resource information is compared with the first register resource information to determine whether the two are consistent. If so, it indicates that the switching chip of the network device has not experienced a soft failure due to external reasons, and the network device can perform corresponding service processing based on the second register resource information. If the second register resource information is inconsistent with the first register resource information, it indicates that the switching chip in the network device has experienced a soft failure. In this case, the first register resource information is sent to the switching chip to repair the second register resource information in the switching chip based on the first register resource information, thereby ensuring that the network device performs corresponding service processing based on the correct register resource information.

[0040] The soft failure protection method for a technical switching chip according to an embodiment of the present invention is applied to a network device, wherein the network device includes a switching chip. The method includes: in response to a soft failure monitoring event being triggered, obtaining first register resource information stored in the network device according to a preset period; reading second register resource information of the switching chip; and when the second register resource information is inconsistent with the first register resource information, sending the first register resource information to the switching chip. Through the technical solution provided by the embodiment of the present invention, by comparing the first register resource information stored in the network device with the second register resource information read from the switching chip in real time, when the two are inconsistent, it is determined that a soft failure has occurred in the switching chip. At this time, the first register resource information is quickly sent to the switching chip to repair the second register resource information, thereby ensuring the normal operation of the network device's services and avoiding service damage caused by the soft failure of the switching chip.

[0041] In some embodiments, the first register resource information includes a first register status value; obtaining the first register resource information stored in the network device includes: obtaining a register status configuration file pre-stored in the network device; and reading the first register status value of each register in the switching chip from the register status configuration file.

[0042] In an embodiment of the present invention, a switching chip of a network device may include one or more registers. Before the network device is put into use, register state values ​​of each register in the switching chip of the network device are set according to the application scenario of the network device, and the register state values ​​are stored in the network device in the form of a configuration file. Therefore, in response to a soft failure detection event being triggered, a register state configuration file pre-stored in the network device is obtained and parsed, and the register state values ​​of each register in the switching chip of the network device are read from the register state configuration file. The register state value read from the register state configuration file is referred to as the first register state value.

[0043] In some embodiments, the second register resource information includes the second register status value of each register in the switching chip; when the second register resource information is inconsistent with the first register resource information, the first register resource information is sent to the switching chip, including: polling each register, and when the second register status value corresponding to the current register is inconsistent with the first register status value, sending the first register status value to the switching chip to update the second register status value of the current register in the switching chip based on the first register status value.

[0044] In an embodiment of the present invention, when the first register resource information is the first register status value of each register in the switching chip, the second register resource information is the second register status value of each register in the switching chip read in real time from the switching chip. Each register is polled to determine whether the second register status value corresponding to the current register is consistent with the first register status value. If not, it indicates that a soft failure has occurred in the current register in the switching chip, resulting in an abnormal second register status value corresponding to the current register. At this time, the first register status value is sent to the switching chip to update the second register status value of the current register in the switching chip based on the first register status value. It can be understood that when the second register status value of the register read from the switching chip is inconsistent with the first register status value of the register pre-stored in the network device (which can also be understood as a processor), it indicates that a soft failure has occurred in the register in the switching chip. In order to avoid the impact of the soft failure on the service function of the network device, the first register status value is sent to the switching chip so that the register in the switching chip performs corresponding service processing based on the correct first register status value.

[0045] In some embodiments, the first register resource information includes first business table item data, and the second register resource information includes second business table item data; obtaining the first register resource information stored in the network device includes: reading the corresponding first business table item data dynamically stored in the network device according to the business type; reading the second register resource information of the switching chip includes: reading the second business table item data corresponding to the business type in the switching chip; when the second register resource information is inconsistent with the first register resource information, sending the first register resource information to the switching chip, including: polling each first business table item data, and when there is no second business table item data consistent with the current first business table item data in the second business table item data, sending the current first business table item data to the switching chip.

[0046] In an embodiment of the present invention, different register hardware resources in a switching chip correspond to different service types and service functions, wherein different service types correspond to different service table item data. The same service type corresponds to one or more service table item data. For example, service types may include ACL services, security policy services, blacklist services, and whitelist services. In response to a soft failure monitoring event being triggered, first service table item data corresponding to the service type dynamically stored in the memory of the network device is read according to the service type at a preset period. Second service table item data corresponding to the service type in the switching chip is then read through a query interface of the switching chip. Each first service table item data is polled to determine whether all read second service table item data contain second service table item data that is consistent with the current first service table item data. If not, this indicates that the second service table item data in the switching chip may be corrupted due to a soft failure of a register resource in the switching chip. In this case, the current first service table item data is sent to the switching chip to repair the second service table item data in the switching chip based on the first service table item data dynamically stored in the memory of the network device.

[0047] In some embodiments, the first register resource information further includes a total number of first service items, and the second register resource information further includes a total number of second service items. When polling each first service item data, if no second service item data consistent with the current first service item data exists in each second service item data, before delivering the current first service item data to the switch chip, the method further includes: determining whether the total number of the second service items is the same as the total number of the first service items. Polling each first service item data, if no second service item data consistent with the current first service item data exists in each second service item data, delivering the current first service item data to the switch chip, including: when the total number of the second service items is different from the total number of the first service items, polling each first service item data, if no second service item data consistent with the current first service item data exists in each second service item data, delivering the current first service item data to the switch chip.

[0048] Optionally, when the total number of the second business table items is the same as the total number of the first business table items, N target business table item data are extracted from all the first business table item data; the N target business table item data are polled, and when there is no second business table item data consistent with the current target business table item data among the second business table item data, the current target business table item data is sent to the switching chip.

[0049] In an embodiment of the present invention, the corresponding first service table item data and the total number of first service table items dynamically stored in the network device memory are read based on the service type. Furthermore, the corresponding second service table item data and the total number of second service table items in the switching chip are read. A determination is made as to whether the total number of first service table items and the total number of second service table items are the same. If not, this indicates that a soft failure of register resources in the switching chip may have caused a corruption in the second service table item data in the switching chip. Therefore, all first service table item data and second service table item data are directly verified. Specifically, each first service table item data is polled to determine whether any second service table item data matches the current first service table item data. If not, the current first service table item data is delivered to the switching chip. If the total number of first service table items and the total number of second service table items are the same, to further determine whether a soft failure has occurred in the switching chip and improve the efficiency of soft failure detection, N pieces of first service table item data are extracted from all first service table item data and used as the target service table item data. Optionally, N pieces of target service table item data may be randomly extracted from all first service table item data, or N pieces of target service table item data may be extracted from all first service table item data according to a preset rule. N is an integer greater than or equal to 1. The N pieces of target service table item data are polled to determine whether any second service table item data consistent with the current target service table item data exists among all second service table item data. If not, it indicates that a soft failure may have occurred in the switching chip. In this case, the current target service table item data is sent to the switching chip, so that the second service table item data in the switching chip can be repaired based on the target service table item data.

[0050] In some embodiments, after sending the first register resource information to the switching chip, it also includes: recording the number of times the first register resource information is sent, and judging whether the first register resource information is successfully sent to the switching chip. If not, returning to execute sending the first register resource information to the switching chip after the target time interval, and increasing the number of sends by 1, until the number of sends is less than the preset number threshold, the first register resource information is successfully sent to the switching chip; wherein, the target time increases with the increase of the number of sends.

[0051] For example, when sending the first register resource information to the switching chip, the target interface for receiving the first register resource information may experience a soft failure, resulting in a failure to send the first register resource information. That is, the switching chip cannot receive the first register resource information. Therefore, after sending the first register resource information to the switching chip, the number of times the first register resource information was sent is recorded, and a determination is made as to whether the first register resource information was successfully sent to the switching chip. If not, the process returns to sending the first register resource information to the switching chip after a target interval, i.e., the first register resource information is sent to the switching chip again, and the number of times the first register resource information was sent is increased by 1. A determination is made as to whether the first register resource information was successfully sent to the switching chip within a preset number threshold. If not, it indicates that the failure to send the first register resource information was not caused by a soft failure of the target interface, but rather by damage to the switching chip. In this case, a switching chip damage alarm is issued. When the first register resource information is successfully sent to the switching chip within the preset number threshold, the number of times the information was sent is reset to 0.

[0052] Because soft failures are temporary, in order to reduce the number of times the first register resource information is sent, the target duration increases as the number of times the first register resource information is sent increases. For example, after the first register resource information fails to be sent for the first time, the first register resource information is sent to the switching chip again after a first duration. If the first register resource information fails to be sent for the second time, the first register resource information is sent to the switching chip again after a second duration, where the second duration is greater than the first duration, such as the second duration is twice the first duration, and so on, until the first register resource information is successfully sent to the switching chip within the predicted number threshold. For example, the preset number threshold can be 3.

[0053] Example 2

[0065] S2110 , determining whether all registers have been polled; if so, returning to executing S210 ; otherwise, returning to executing S240 .

[0066] The soft failure protection method for a switching chip provided in an embodiment of the present invention compares a first register status value pre-stored in a network device with a second register status value read in real time from the switching chip. When the two are inconsistent, it is determined that a soft failure has occurred in the switching chip. At this time, the first register status value is quickly sent to the switching chip to update the second register status value of the register in the switching chip based on the first register status value, thereby ensuring the normal operation of the network device's business and avoiding business damage caused by the soft failure of the switching chip.
