Description

TECHNICAL FIELD

[0001] Embodiments of the present disclosure relate to the technical field of computer, and specifically to a link state detection method, device, equipment and computer readable medium. BACKGROUND

[0002] The link state is detected to find whether the link exists fault. At present, when the link state is detected, the commonly used way is to detect the link by hardware, slow Hello mechanism in routing protocol or bidirectional forwarding detection function, so as to determine whether the link fails.

[0003] However, the inventor finds that when the link state is detected by using the above way, the following technical problems often exist: when the hardware is used to detect the link and the device does not support the hardware detection, the adaptability of using the hardware to detect the link is poor, which leads to poor practicability of detecting the link by using the hardware, and when the hardware is used to detect the link, the hardware needs to be additionally configured to detect the link; when the slow Hello mechanism in the routing protocol is used to detect, the time consumption of detection is long, which leads to long time consumption of finding the link fault, and causes a large amount of transmission data to be lost due to the link fault not being found; when the bidirectional forwarding detection function is used to detect the link, the development steps of the developer are more complicated, which leads to long time consumption of development, and causes long time consumption and more computing resources to be consumed to detect the link.

[0004] The above information disclosed in the background section is only intended to enhance the understanding of the background of the present inventive concept, and therefore, it can include information that does not form the prior art known by those skilled in the art in the country. SUMMARY

[0006] Some embodiments of the present disclosure propose a link state detection method, device, electronic equipment and computer readable medium to solve one or more of the technical problems mentioned in the background section.

[0007] In a first aspect, some embodiments of the present disclosure provide a link state detection method, which comprises: in response to detecting start information of a target link terminal, the start information containing target identification information of the target link terminal, the target link terminal supporting a network control packet protocol, performing the following steps: sending a link state detection packet to the target link terminal according to the target identification information, receiving feedback information of the target link terminal according to the link state detection packet, and determining a current link state between the configuration terminal and the target link terminal according to the feedback information.

[0008] In a second aspect, some embodiments of the present disclosure provide a link state detection device, which supports a private link detection protocol, and comprises: a link detection unit configured to, in response to detecting start information of a target link terminal, send a link state detection packet to the target link terminal according to target identification information in the start information, receive feedback information of the target link terminal according to the link state detection packet, and determine a current link state between the configuration terminal and the target link terminal according to the feedback information; wherein the target link terminal supports a network control packet protocol, and the start information contains target identification information of the target link terminal.

[0009] In a third aspect, some embodiments of the present disclosure provide a primary / backup switching method of a redundant network, the redundant network comprising a primary switching device and a backup switching device, the backup switching device supporting a private link detection protocol, the backup switching device being configured with a preset timeout period and a preset sending period, the primary switching device supporting a network control packet protocol, the method being applied to the backup switching device, and the method comprising: in response to detecting monitoring start information containing target identification information of the primary switching device, sending a link state detection packet to the primary switching device according to the target identification information within the preset timeout period and with the preset sending period, and switching to the primary switching device if no reply packet fed back by the primary switching device is received within the preset timeout period.

[0010] In a fourth aspect, some embodiments of the present disclosure provide a redundant network, the redundant network comprising a primary switching device and a backup switching device, the backup switching device supporting a private link detection protocol, the backup switching device being configured with a preset timeout period and a preset sending period, the primary switching device supporting an ICMP (network control packet) protocol, and the backup switching device comprising: a detection and switching module configured to, in response to detecting monitoring start information containing target identification information of the primary switching device, send a link state detection packet to the primary switching device according to the target identification information within the preset timeout period and with the preset sending period, and switch to the primary switching device if no reply packet fed back by the primary switching device is received within the preset timeout period.

[0011] In a fifth aspect, some embodiments disclosed herein provide an electronic device, comprising: one or more processors; and a memory device storing one or more programs, wherein the one or more programs, when executed by the one or more processors, cause the one or more processors to perform the method described in any implementation of the first aspect.

[0012] In a sixth aspect, some embodiments disclosed herein provide a computer-readable medium having stored thereon a computer program, wherein the computer program, when executed by a processor, performs the method described in any implementation of the first aspect.

[0013] The above various embodiments of the present disclosure have the following beneficial effects: through the link state detection method of some embodiments of the present disclosure, the adaptability of device detection is improved, the situation that a large amount of transmission data is lost due to undetected link failure is reduced, the time-consuming of link detection is shortened, the waste of computing resources is reduced, and additional hardware configuration is not required for link detection. Specifically, the reasons for causing the need for additional hardware configuration for detection, the situation that a large amount of transmission data is lost due to undetected link failure, the long time-consuming of link state detection, and the waste of computing resources are as follows: when using hardware for link detection and the device does not support hardware detection, the adaptability of using hardware for link detection is poor, which leads to poor practicability of link detection by hardware, and additional hardware configuration is required for link detection when using hardware; when detection is performed through the slow Hello mechanism in the routing protocol, the time-consuming of detection is long, which leads to a long time-consuming of discovering link failure and a large amount of transmission data lost due to undetected link failure; when the link is detected through the bidirectional forwarding detection function, the development steps of the developer are complicated, which leads to a long development time-consuming, a long time-consuming of implementing link detection, and a large amount of computing resources consumed. Based on this, in response to detecting the start information of the target link terminal, the target identification information of the target link terminal is contained in the start information, the target link terminal supports the network control message protocol, and the following steps are performed: sending a link state detection message to the target link terminal according to the target identification information, receiving feedback information of the target link terminal according to the link state detection message, and determining the link state between the configuration terminal and the target link terminal according to the feedback information. Thus, when the start information of the target link terminal is detected, the link state detection message can be sent, and the feedback information can be determined according to the feedback information, so that the link state can be determined according to the feedback information. Because the link state is generated according to the private link detection protocol supported by the configuration terminal, rather than generated according to hardware detection, additional hardware configuration is not required for link detection. Because the interval time of sending the link state detection message corresponding to the private link detection protocol can be configured as 20 ms, and the timeout time configuration can be configured as 60 ms. The time interval of sending the link state detection message of the existing protocol standard for link detection is 1 second. The timeout time configuration is 3 seconds, and because the existing link detection protocol cannot be cross-network detection, the time for link detection in multiple networks is long, and the private link detection protocol can cross-network detection, so the time-consuming of link state detection can be shortened, and the situation that a large amount of transmission data is lost due to undetected link failure can be reduced.In addition, the private link state detection protocol is based on the network control message protocol, and the target link terminal supports the network control message protocol, so that the link state is detected by the private link state detection protocol based on the network control message protocol supported by most devices. Instead of being based on the bidirectional forwarding detection function, thereby simplifying the development steps of the developer, shortening the development time, and reducing the waste of computing resources. Therefore, the time-consuming of the link state detection is shortened, the adaptability of the device detection is improved, the speed of the link state detection is improved, the situation that a large amount of transmission data is lost due to link failure is reduced, the link state does not need to be detected by additional hardware configuration, and the waste of computing resources is reduced.

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

[0026] Figure 1 Flow 100 of some embodiments of the link state detection method according to the present disclosure is shown. The link state detection method comprises the following steps:

[0027] Step 101, in response to detecting the start information of the target link terminal, the start information contains the target identification information of the target link terminal, the target link terminal supports network control message protocol, the following steps are executed: sending a link state detection message to the target link terminal according to the target identification information, receiving feedback information of the target link terminal according to the link state detection message, and determining the current link state between the configuration terminal and the target link terminal according to the feedback information.

[0028] In some embodiments, in response to detecting start information of a target link terminal, the start information containing target identification information of the target link terminal, the target link terminal supporting a network control packet protocol, the performing subject can perform the following steps: sending a link state detection packet to the target link terminal according to the target identification information, receiving feedback information of the target link terminal according to the link state detection packet, and determining a current link state between the configuration terminal and the target link terminal according to the feedback information. The start information can be information for starting to detect the link state. The start information can contain target identification information of multiple target link terminals, and the multiple target link terminals can all support the network control packet protocol. The network control packet protocol can be an ICMP protocol. The target identification information can be an IP (Internet Protocol) address of the target link terminal. The target link terminal can be, but is not limited to, one or more of the following: a three-layer switch, a server, a PC, a router, and a firewall. The feedback information can be a reply of the target link terminal device to the link state detection packet. The current link state can be a normal link or a link failure. The link state detection packet can be an ICMP request. The network control packet protocol can be an ICMP function. The feedback information can be an ICMP reply. In practice, in response to detecting start information of a target link terminal, the start information containing target identification information of the target link terminal, the target link terminal supporting a network control packet protocol, the performing subject can perform the following steps: sending a link state detection packet to the target link terminal according to the target identification information, receiving feedback information of the target link terminal according to the link state detection packet, and determining a current link state between the configuration terminal and the target link terminal according to the feedback information.

[0029] In some optional implementations of some embodiments, the execution subject can send the link state detection packet to the target link terminal in the preset sending period within the preset timeout period. If a reply packet fed back by the target link terminal is received within the preset timeout period, it is determined that the current link between the configuration terminal and the target link terminal is normal, otherwise, it is determined that the current link between the configuration terminal and the target link terminal is abnormal. The preset timeout period and the preset sending period of the link state detection packet can be contained in the start information. The preset timeout period can be greater than the preset sending period. The preset timeout period can be a preset number of times of the preset sending period. For example, the preset number of times can be 3 times. The preset sending period can be an interval time at which the execution subject sends the link state detection packet. The preset timeout period can be a maximum interval time during which the reply packet fed back by the target link terminal is not received. The preset sending period and the preset timeout period can be time periods configured by default. For example, the preset sending period can be 20 ms, and the preset timeout period can be 60 ms.

[0030] In some optional implementations of some embodiments, in response to detecting the start information of the target link terminal, the execution subject can adjust the preset sending period and the preset timeout period according to the configuration information to obtain a configuration sending period and a configuration timeout period, and send the link state detection packet to the target link terminal in the configuration sending period within the configuration timeout period. If a reply packet fed back by the target link terminal is received within the configuration timeout period, it is determined that the current link between the configuration terminal and the target link terminal is normal, otherwise, it is determined that the current link between the configuration terminal and the target link terminal is abnormal. The configuration information can be a new configuration of link detection. The configuration information can represent change information of the default configuration of link detection. The configuration sending period can be a period of sending the link state detection packet after the change. The configuration timeout period can be a maximum time period during which the feedback information of the link state detection packet is not received after the change.

[0031] The timeout period and the sending period can be configured before link state detection, which improves the flexibility of link state detection and meets the link detection requirements in different scenarios.

[0032] It can be understood that in the above two embodiments, the purpose of setting the timeout period to be greater than the sending period is to send the link state detection packet multiple times within the timeout period to avoid the situation that the current link state detection is wrong due to the fact that the reply packet of the target link terminal is not received because the link state detection packet has a problem.

[0033] Optionally, after step 101, first, the above execution subject can acquire the target link state of the private link detection protocol in the last timeout period in response to determining that the above configuration information includes protocol linkage configuration information representing configuring the private link detection protocol and the target link detection protocol for link state detection linkage. The target link detection protocol can be, but is not limited to, one of the following: static routing, network address translation protocol, virtual routing redundancy protocol, and link state routing protocol. The target link state can be the previous link state of the current link state detected. Thus, the target link state detected by the private link detection protocol can be obtained.

[0034] Then, the current link state detected by the private link detection protocol can be notified to the linkage device supporting the target link detection protocol in response to determining that the current link state detected by the private link detection protocol is inconsistent with the target link state, so that the linkage device adjusts the state according to the current link state. The state adjustment can be understood as that when the private link detection protocol is not linked with the target link detection protocol, the linkage device supporting the target link detection protocol only receives the link state detected by the target link detection protocol. When the private link detection protocol is linked with the target link detection protocol, the linkage device supporting the target link detection protocol receives the link state detected by the target link detection protocol and the link state detected by the private link detection protocol. Because the preset sending period and the preset timeout period of the private link detection protocol can be flexibly configured, a shorter period can be configured, and the private link detection protocol will definitely detect the current link state earlier than the target link detection protocol, so that the linkage device can know the current link state earlier by sending the link state detected by the private link detection protocol in time, especially when the link state changes, so as to make state adjustment processing in time. For example, the target link detection protocol can be a VRRP protocol, when the linkage device receives the link state sent by the private link detection protocol as link failure, the linkage device quickly performs master-slave switching and adjusts to the standby link to replace the failed link to perform forwarding work. Because the private link detection protocol detects the link state in a shorter time, the interruption time of the data flow can be shortened. The linkage device will adjust to receive only the link state detected by the private link detection protocol which detects the link state faster.

[0035] It is worth mentioning that in the protocol linkage configuration scheme, one linkage device can simultaneously receive the current link state detected by the private link detection protocol and the current link state detected by the target link detection protocol. When the link state does not change, the current link state detected by the target link detection protocol is used as the state of the current link, which does not have too much influence on the reception and forwarding of data. When the link state changes, the current link state detected by the private link detection protocol is sent to the linkage device, so that the linkage device can obtain the changed state of the link in time, make adjustment, and improve the reliability of data forwarding.

[0036] The various embodiments disclosed in the present application have the following beneficial effects: the link state detection method of some embodiments of the present application improves the adaptability of device detection, reduces the loss of a large amount of transmission data due to undetected link faults, shortens the time-consuming of link detection, reduces the waste of computing resources, and does not require additional hardware configuration for link detection. Specifically, the reasons for the need for additional hardware configuration for detection, the frequent loss of a large amount of transmission data due to undetected link faults, the long time-consuming of link state detection, and the waste of computing resources are as follows: when using hardware for link detection and the device does not support hardware detection, the adaptability of using hardware for link detection is poor, resulting in poor practicability of link detection by hardware, and additional hardware configuration is required for link detection when using hardware; when detecting by the slow Hello mechanism in the routing protocol, the time-consuming of detection is long, resulting in a long time-consuming of discovering link faults and a large amount of transmission data lost due to undetected link faults; when detecting the link by the bidirectional forwarding detection function, the development steps of the developer are complicated, resulting in a long development time-consuming, a long time-consuming of implementing link detection, and a large amount of computing resources consumed. Based on this, the link state detection method of some embodiments of the present application, in response to detecting the start information of the target link terminal, the start information containing the target identification information of the target link terminal, and the target link terminal supporting the network control message protocol, performs the following steps: sending a link state detection message to the target link terminal according to the target identification information, receiving feedback information of the target link terminal according to the link state detection message, and determining the link state between the configuration terminal and the target link terminal according to the feedback information. Thus, when the start information of the target link terminal is detected, the link state detection message can be sent, and the feedback information can be received to determine whether the link state has failed according to the feedback information. Because the link state is generated according to the private link detection protocol supported by the configuration terminal, rather than generated according to hardware detection, additional hardware configuration is not required for link detection. Because the interval time of sending the link state detection message corresponding to the private link detection protocol can be configured as 20 ms, and the timeout time configuration can be configured as 60 ms. The time interval of sending the link state detection message of the existing link detection protocol standard is 1 second. The timeout time configuration is 3 seconds, and because the existing link detection protocol cannot perform cross-network detection, the time for detecting the link in multiple networks is long, and the private link detection protocol can perform cross-network detection of the link. Therefore, the time-consuming of detecting the link state can be shortened, and the loss of a large amount of transmission data due to undetected link faults can be reduced.Further, the private link state detection protocol is based on the network control message protocol, and the target link terminal supports the network control message protocol, so that the link state is detected by the private link state detection protocol based on the network control message protocol supported by most devices. Instead of being based on the bidirectional forwarding detection function, thereby simplifying the development steps of the developer, shortening the development time, and reducing the waste of computing resources. Therefore, the time-consuming of the link state detection is shortened, the adaptability of the device detection is improved, the speed of the link state detection is improved, a large amount of transmission data loss due to link failure is reduced, the link state detection does not need to be detected by additional hardware, and the waste of computing resources is reduced.

[0037] Figure 2 A flowchart of a method for switching a master and a backup of a redundant network according to the present disclosure is shown.

[0038] The redundant network in the method for switching a master and a backup of a redundant network includes a master switching device and a backup switching device. The backup switching device supports a private link state detection protocol. The backup switching device is configured with a preset timeout period and a preset sending period. The master switching device supports a network control message protocol. The method is applied to the backup switching device. The method includes the following steps:

[0039] In step 201, in response to detecting monitoring start information containing target identification information of the master switching device, link state detection messages are sent to the master switching device at a preset sending period within a preset timeout period according to the target identification information. If no reply message fed back by the master switching device is received within the preset timeout period, the master switching device is switched.

[0040] In some embodiments, the execution subject can send the link state detection message to the master switching device at the preset sending period within the preset timeout period according to the target identification information in response to detecting monitoring start information containing target identification information of the master switching device. If no reply message fed back by the master switching device is received within the preset timeout period, the master switching device is switched. The redundant network includes a master switching device and a backup switching device. The backup switching device supports a private link state detection protocol. The backup switching device is configured with a preset timeout period and a preset sending period. The master switching device supports a network control message protocol. The method is applied to the backup switching device. The monitoring start information can be start information of the master switching device.

[0041] It can be understood that the monitoring start information containing the target identification information of the master switching device can be configured when the redundant network starts to work, that is, the backup switching device starts to monitor the state of the master switching device.

[0042] Further referring to Figure 3 , as the implementation of the method shown in the above figures, the present disclosure provides some embodiments of a link state detection device, which device embodiments correspond to those method embodiments, and the device can be specifically applied in various electronic devices. Figure 1

[0043] As shown in Figure 3 , the link state detection device 300 of some embodiments includes: the device supports a private link probe protocol, and the device includes: a link detection unit 301 configured to, in response to detecting startup information of a target link terminal, send a link state detection packet to the target link terminal according to target identification information in the startup information, receive feedback information of the target link terminal according to the link state detection packet, and determine the current link state between the configuration terminal and the target link terminal according to the feedback information; wherein the target link terminal supports a network control packet protocol, and the startup information contains target identification information of the target link terminal.

[0044] It can be understood that the units recorded in the device 300 correspond to the steps in the method described with reference to Figure 1 . Therefore, the operations, features and beneficial effects described above for the method also apply to the device 300 and the units contained therein, and will not be repeated here.

[0045] Figure 4 An example structure diagram of some embodiments of the redundant network disclosed by the present disclosure is shown. A redundant network, the redundant network includes a primary switching device 403 and a backup switching device 401, the backup switching device supports a private link probe protocol, the backup switching device is configured with a preset timeout period and a preset sending period, the primary switching device supports a network control packet protocol, and the backup switching device includes: a detection switching module 402 configured to, in response to detecting monitoring startup information containing target identification information of the primary switching device, send the link state detection packet to the primary switching device according to the target identification information within the preset timeout period with the preset sending period, and if no reply packet feedback by the primary switching device is received within the preset timeout period, switch to the primary switching device.

[0046] ​In some embodiments, the execution entity may configure the detection switching module to, in response to detecting monitoring start information containing target identification information of the primary switching device, send the link status detection message to the primary switching device within the preset timeout period and at the preset transmission period according to the target identification information. If no reply message is received from the primary switching device within the preset timeout period, the primary switching device is switched over. The redundant network includes a primary switching device and a backup switching device. The backup switching device supports a private link detection protocol. The backup switching device is configured with a preset timeout period and a preset transmission period. The primary switching device supports the Network Control Message Protocol. It should be noted that... Figure 4 The switch 404 shown is a general-purpose switch that forwards data to various computer terminals 405 and expands ports to enable the main and backup switching devices to connect to more computer terminals.

[0047] The redundant network in this embodiment enables rapid switching from backup switching equipment to primary switching equipment, with a switching time of milliseconds, greatly reducing the problem of data not being forwarded in time or data loss caused by long switching times between primary and backup switching equipment.
