Description

Technical Field

[0001] The present application relates to the field of server technology, and in particular to a network detection method, apparatus, computer equipment, computer-readable storage medium, and computer program product. Background Art

[0002] In a distributed storage system, there are multiple storage nodes, and each storage node will establish a network connection with other storage nodes in the distributed storage system for data transmission. Before and after the network connection is established, a network detection method is needed to detect whether the physical link between the two storage nodes is normal.

[0003] In the current network detection method, the first storage node continuously sends a detection request message to the second storage node according to a preset time period, and receives a detection response message from the second storage node, until the first storage node receives the detection response message, and the first storage node determines that the physical link from the first storage node to the second storage node is normal.

[0004] However, the current network detection method, because there are multiple storage nodes in the distributed storage system, and each storage node will continuously send detection request messages, resulting in a large number of detection request messages in the distributed storage system. Therefore, the current network detection method will cause a large pressure on the distributed storage system. Summary of the invention

[0005] Based on this, it is necessary to provide a network detection method, apparatus, computer equipment, computer-readable storage medium and computer program product to address the above technical issues.

[0006] In a first aspect, the present application provides a network detection method, which is applied to a first storage node and includes:

[0007] If the network connection is abnormal or does not exist, send a detection request message to the second storage node and determine the detection result;

[0008] If the network connection is normal and meets the network interaction condition, the first time period is increased according to a preset increasing rule, and the detection request message is sent to the second storage node according to the increased first time period to obtain a detection result.

[0009] In the above network detection method, when the network connection is abnormal or does not exist, a detection request message is sent to the second storage node once to determine the detection result, thereby avoiding continuous sending of detection request messages and reducing the number of detection request messages. Furthermore, when the network connection is normal, by increasing the first time period and sending the detection request message based on the increased first time period, the number of detection request messages is reduced, thereby reducing the pressure on the distributed storage system.

[0010] In one embodiment, sending a detection request message to the second storage node once and determining the detection result includes:

[0011] Sending a detection request message to the second storage node once, and receiving a detection response message sent by the second storage node according to a second time period;

[0012] Determining whether the detection response message is received within the second time period;

[0013] If the detection response message is received within the second time period, it is determined that the detection result corresponding to the detection request message is detection success.

[0014] In this embodiment, by sending a detection request message to the second storage node once, and receiving a detection response message sent by the second storage node according to the second time period, the number of detection request messages is reduced, thereby reducing the pressure on the distributed storage system. In addition, when the physical link is normal, the detection result can be quickly determined by sending a detection request message once, thereby quickly establishing a network connection between storage nodes, and improving the efficiency of establishing a network connection.

[0015] In one of the embodiments, after determining whether the detection response message is received within the second time period, the method further includes:

[0016] If the detection response message is not received within the second time period, updating the number of fast detection times;

[0017] Determining whether the number of rapid detections exceeds a preset rapid detection number threshold;

[0018] If the number of fast detection times does not exceed the fast detection times threshold, execute the step of receiving the detection response message sent by the second storage node according to the second time period until the detection response message is received within the second time period or the number of fast detection times exceeds the fast detection times threshold.

[0019] In this embodiment, if no detection response message is received within the second time period and the updated rapid detection times do not exceed the rapid detection times threshold, the detection response message continues to be received, thereby improving the success rate of the network detection method.

[0020] In one embodiment, after determining whether the number of rapid detections exceeds a preset rapid detection number threshold, the method further includes:

[0021] If the number of rapid detections exceeds the rapid detection number threshold, determining that the initial detection result is a failure;

[0022] The detection request message is sent to the second storage node according to a first time period, and the initial detection result is updated to obtain a detection result.

[0023] In this embodiment, when the number of rapid detection times exceeds the rapid detection times threshold, a detection request message is sent to the second storage node according to the first time period, the normal detection mode is started, and the success rate of the network detection method is improved.

[0024] In one of the embodiments, if the network connection is normal and satisfies the network interaction condition, before increasing the first time period according to a preset incremental rule, the method further includes:

[0025] If the network connection is normal, sending a detection request message to the second storage node based on a first time period, and receiving a detection response message sent by the second storage node according to a third time period;

[0026] Determine whether a detection response message sent by the second storage node is received within a fourth time period, and obtain a first determination result;

[0027] If the first judgment result is that the detection response message is received within the fourth time period, it is determined that the network interaction condition is not met, and the detection result is determined to be a detection success;

[0028] If the judgment result is that the detection response message is not received within the fourth time period, it is determined that the network interaction condition is met.

[0029] In this embodiment, if the network connection is normal, a detection request message is sent according to the first time period, and it is determined whether a detection response message sent by the second storage node is received within the fourth time period to obtain a first judgment result. Then, it is determined whether the network interaction condition is met according to the first judgment result, so as to facilitate the subsequent execution of the network detection method.

[0030] In one embodiment, increasing the first time period according to a preset increasing rule, and sending the detection request message to the second storage node according to the increased first time period to obtain the detection result includes:

[0031] Increase the first time period to twice the current first time period to obtain an increased first time period, and increase the third time period to twice the current third time period to obtain an increased third time period;

[0032] Update the normal detection times, and determine whether the normal detection times exceed a preset normal detection times threshold;

[0033] If the number of normal detection times does not exceed the detection times threshold, sending the detection request message to the second storage node according to the increased first time period, and receiving the detection response message sent by the second storage node according to the increased third time period;

[0034] Determine whether a detection response message sent by the second storage node is received within a fourth time period, obtain a second determination result, and determine a detection result based on the second determination result.

[0035] In this embodiment, if the network connection is normal, the first time period is increased to obtain an increased first time period, and a detection request message is sent based on the increased first time period, thereby reducing the number of detection request messages and reducing the pressure on the distributed storage system.

[0036] In one embodiment, determining the detection result based on the second judgment result includes:

[0037] If the second judgment result is that the detection response message is received within a fourth time period, determining that the detection result is a detection success;

[0038] If the second judgment result is that the detection response message is not received within the fourth time period, execute the step of increasing the first time period to twice the current first time period to obtain the increased first time period, until the detection response message is received within the fourth time period or the normal detection number exceeds the normal detection number threshold, and determine the detection result.

[0039] In this embodiment, the detection result is determined by the second judgment result, and it is clarified whether the physical link between the storage nodes is normal, which facilitates the subsequent network connection between the storage nodes.

[0040] In a second aspect, the present application also provides a network detection device, including:

[0041] A first sending module, configured to send a detection request message to the second storage node once if the network connection is abnormal or does not exist, and determine the detection result;

[0042] The second sending module is used to increase the first time period according to a preset increasing rule if the network connection is normal and meets the network interaction conditions, and send the detection request message to the second storage node according to the increased first time period to obtain the detection result.

[0043] In a third aspect, the present application further provides a computer device, including a memory and a processor, wherein the memory stores a computer program, and when the processor executes the computer program, the following steps are implemented:

[0044] If the network connection is abnormal or does not exist, send a detection request message to the second storage node and determine the detection result;

[0045] If the network connection is normal and meets the network interaction condition, the first time period is increased according to a preset increasing rule, and the detection request message is sent to the second storage node according to the increased first time period to obtain a detection result.

[0046] In a fourth aspect, the present application further provides a computer-readable storage medium having a computer program stored thereon, wherein when the computer program is executed by a processor, the following steps are implemented:

[0048] If the network connection is normal and meets the network interaction condition, the first time period is increased according to a preset increasing rule, and the detection request message is sent to the second storage node according to the increased first time period to obtain a detection result.

[0049] In a fifth aspect, the present application further provides a computer program product, including a computer program, which implements the following steps when executed by a processor:

[0050] If the network connection is abnormal or does not exist, send a detection request message to the second storage node and determine the detection result;

[0051] If the network connection is normal and meets the network interaction condition, the first time period is increased according to a preset increasing rule, and the detection request message is sent to the second storage node according to the increased first time period to obtain a detection result.

Using this method, when the network connection is abnormal or does not exist, a detection request message is sent to the second storage node once to determine the detection result, avoiding the continuous sending of detection request messages and reducing the number of detection request messages. In addition, when the network connection is normal, by increasing the first time period and sending the detection request message based on the increased first time period, the number of detection request messages is reduced, thereby reducing the pressure on the distributed storage system.

[0067] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0068] The network detection method provided in the embodiment of the present application can be applied to Figure 1 In the distributed storage system 100 shown. The distributed storage system 100 includes multiple storage nodes. The first storage node 110 is any one of the multiple storage nodes. The second storage node 120 is a storage node among the multiple storage nodes that needs to establish a network connection with the first storage node 110 or has established a network connection. The storage node can be a server or a computer device, and can also be a cloud server that provides cloud computing services.

[0069] In an exemplary embodiment, Figure 2 As shown, a network detection method is provided, which is applied to Figure 1 The first storage node 110 (hereinafter referred to as the first storage node) in the example is used for description, and the following steps 202 to 204 are included. Among them:

[0070] Step 202: If the network connection is abnormal or does not exist, a detection request message is sent to the second storage node, and a detection result is determined.

[0071] The network connection is a network connection between the first storage node and the second storage node.

[0072] In implementation, if the network connection with the second storage node is abnormal or does not exist, the first storage node sends a detection request message to the second storage node and receives a detection response message sent by the second storage node. The first storage node determines the detection result based on the reception time of the detection response message.

[0073] Specifically, the first storage node stores the network configuration information of the first storage node. Based on the network configuration information, the first storage node determines the network connection status between the first storage node and the second storage node. If the network connection status is that the network connection is abnormal or does not exist, the first storage node performs a network detection in a fast detection mode. Specifically, the first storage node sends a detection request message to the second storage node through the physical link between the first storage node and the second storage node, and receives a detection response message sent by the second storage node. Then, the first storage node determines the detection result based on the reception time of the detection response message.

[0074] In an exemplary embodiment, the network configuration information includes network connection information of each storage node. The first storage node queries whether there is network connection information of the second storage node in the network connection information. If there is no network connection information of the second storage node, the first storage node determines that the network connection does not exist. If there is network connection information of the second storage node, the first storage node determines whether the network connection status in the network connection information is normal. If the network connection status is normal, the first storage node determines that the network connection is normal. If the network connection status is abnormal, the first storage node determines that the network connection is abnormal. If the network connection status is abnormal or does not exist, the first storage node sends a detection request message to the second storage node through the physical link between the first storage node and the second storage node. If the physical link is normal, the second storage node will receive the detection request message and send a detection response message to the first storage node. The first storage node receives the detection response message and determines the detection result based on the reception time of the detection response message.

[0075] Optionally, the probe request message may be, but is not limited to, a ping (Packet Internet Groper, Chinese name Internet Packet Explorer) message, and the embodiment of the present application does not limit the probe request message.

[0076] Step 204: if the network connection is normal and meets the network interaction condition, increase the first time period according to a preset increasing rule, and send a detection request message to the second storage node according to the increased first time period to obtain a detection result.

[0077] In implementation, the first storage node is pre-set with network interaction conditions and incrementing rules. If the network connection with the second storage node is normal and meets the preset network interaction conditions, the first storage node increases the first time period according to the preset incrementing rules to obtain the increased first time period. Then, the first storage node sends a detection request message to the second storage node based on the increased first time period, and determines the detection result.

[0078] Specifically, the network interaction condition set in the first storage node is that no detection response message is received within a fourth time period. If the network connection with the second storage node is normal, the first storage node performs network detection in normal detection mode. Specifically, the first storage node sends a detection request message to the second storage node according to the first time period, and determines whether the detection response message sent by the second storage node is received within the fourth time period. If the detection response message is not received within the fourth time period, the first storage node determines that the network interaction condition is met, and increases the first time period according to a preset incremental rule to obtain the increased first time period. Then, the first storage node sends a detection request message to the second storage node based on the increased first time period, and determines the detection result.

[0079] In an optional embodiment, the incrementing rule is to increment the first time period according to the first time period increment value and to increment the third time period by a preset third time period increment value. If the network connection is normal and the network interaction condition is met, the first storage node adds the first time period and the first time period increment value to obtain the increased first time period. At the same time, the third storage node adds the third time period and the third time period increment value to obtain the increased third time period. Then, the first storage node sends a detection request message to the second storage node based on the increased first time period and determines the detection result.

[0080] In the above network detection method, when the network connection is abnormal or does not exist, a detection request message is sent to the second storage node once to determine the detection result, thereby avoiding continuous sending of detection request messages and reducing the number of detection request messages. Furthermore, when the network connection is normal, by increasing the first time period and sending the detection request message based on the increased first time period, the number of detection request messages is reduced, thereby reducing the pressure on the distributed storage system.

[0081] In an exemplary embodiment, Figure 3 As shown, the specific processing process of step 202 includes steps 302 to 306. Among them:

[0082] Step 302: Send a detection request message to the second storage node once, and receive a detection response message sent by the second storage node according to a second time period.

[0083] In implementation, a second time period is preset in the first storage node. The first storage node sends a detection request message to the second storage node only once. Then, the first storage node attempts to receive a detection response message sent by the second storage node at a time interval corresponding to the preset second time period.

[0084] Specifically, the second time period is 1 ms (milliseconds). The first storage node sends a detection request message to the second storage node based on the physical link between the first storage node and the second storage node. If the physical link is normal, the second storage node receives the detection request message and sends a detection response message to the first storage node based on the physical link. The first storage node attempts to receive the detection response message sent by the second storage node every 1 ms.

[0085] In an exemplary embodiment, if the network connection is abnormal, the first storage node needs to detect whether the physical link between the first storage node and the second storage node is normal to determine the cause of the abnormal network connection. If the network connection does not exist, the first storage node needs to establish a network connection with the second storage node. Before establishing the network connection between the first storage node and the second storage node, it is necessary to first detect whether the physical link between the first storage node and the second storage node is normal. Therefore, if the network connection is abnormal or does not exist, the first storage node sends a detection request message to the second storage node based on the physical link between the first storage node and the second storage node. If the physical link is normal, the second storage node will receive the detection request message and send a detection response message to the first storage node based on the physical link. The first storage node attempts to receive the detection response message sent by the second storage node at a time interval corresponding to the second time period.

[0086] Optionally, the second time period can be set to, but is not limited to, 1 ms according to rapid detection requirements. The embodiment of the present application does not limit the second time period.

[0087] Step 304: Determine whether a detection response message is received within a second time period.

[0088] In implementation, the first storage node determines whether a detection response message sent by the second storage node is received within a second time period.

[0089] Specifically, if the physical link between the first storage node and the second storage node is normal, the first storage node will receive the detection response message sent by the second storage node within the second time period. The second time period here is a second time period within the fast detection number threshold.

[0090] Step 306: If a probe response message is received within the second time period, it is determined that the probe result corresponding to the probe request message is a successful probe.

[0091] In implementation, if the first storage node receives a detection response message within the second time period, the first storage node determines that the detection result corresponding to the detection request message is a detection success, and determines that the physical link between the first storage node and the second storage node is in a normal state.

[0092] Specifically, the second time period is 1ms. If the first storage node receives the detection response message sent by the second storage node within 1ms, the first storage node determines that the detection result corresponding to the detection request message is a successful detection, and determines that the physical link between the first storage node and the second storage node is in a normal state. If the network connection between the first storage node and the second storage node does not exist and the detection result is a successful detection, the first storage node establishes a network connection with the second storage node. If the network connection between the first storage node and the second storage node is abnormal and the detection result is a successful detection, the first storage node determines that the cause of the abnormality is not the disconnection of the physical link between the first storage node and the second storage node, and re-establishes the network connection between the first storage node and the second storage node.

[0093] In this embodiment, by sending a detection request message to the second storage node once, and receiving a detection response message sent by the second storage node according to the second time period, the number of detection request messages is reduced, thereby reducing the pressure on the distributed storage system. In addition, when the physical link is normal, the detection result can be quickly determined by sending a detection request message once, thereby quickly establishing a network connection between storage nodes, and improving the efficiency of establishing a network connection.

[0094] In an exemplary embodiment, if no detection response message is received within the second time period, it is necessary to continue to receive detection response messages according to the number of fast detection times. Figure 4 As shown, after step 304 is executed, the specific processing process of the network detection method also includes steps 402 to 406. Among them:

[0095] Step 402: If no detection response message is received within the second time period, the number of rapid detection times is updated.

[0096] In implementation, the first storage node is pre-set with a fast detection number. If the first storage node does not receive a detection response message sent by the second storage node within the second time period, the first storage node updates the fast detection number to obtain an updated fast detection number.

[0097] Specifically, the number of fast detections pre-set in the first storage node is 0. The second time period is 1 ms. If the first storage node does not receive a detection response message returned by the second storage node within 1 ms, the first storage node adds 1 to the current number of fast detections to obtain an updated number of fast detections.

[0098] In an exemplary embodiment, the current number of fast detections is 499. If the first storage node does not receive a detection response message fed back by the second storage node within the second time period, the first storage node adds 1 to the current number of fast detections, and obtains an updated number of fast detections of 500.

[0099] Step 404, determining whether the number of rapid detections exceeds a preset rapid detection number threshold.

[0100] In implementation, a fast detection threshold is preset in the first storage node. The first storage node determines whether the updated fast detection number threshold exceeds the preset fast detection number threshold.

[0101] Specifically, the updated fast detection coefficient is 500 times. The fast detection number threshold is 1000 times. The first storage node determines that the updated fast detection number does not exceed the preset fast detection number threshold.

[0102] In an exemplary embodiment, since there may be a large distance between the first storage node and the second storage node, the data transmission time between the first storage node and the second storage node is long, so that within the second time period, the detection request message may not reach the second storage node or the detection response message may not reach the first storage node, and multiple rapid detections are required. Therefore, a rapid detection number threshold is set in the first storage node to ensure the transmission of the detection request message and the detection response message. If the first storage node does not receive the detection response message in the second time period, it updates the rapid detection request and determines whether the rapid detection number exceeds the rapid detection number threshold.

[0103] Optionally, the threshold of the number of rapid detection times can be set to, but is not limited to, 1000 times, which is determined according to the rapid detection requirements. The embodiment of the present application does not limit the threshold of the number of rapid detection times.

[0104] Step 406, if the number of fast detection times does not exceed the fast detection times threshold, execute the step of receiving the detection response message sent by the second storage node according to the second time period until the detection response message is received within the second time period or the number of fast detection times exceeds the fast detection times threshold.

[0105] In implementation, if the number of rapid detections does not exceed the rapid detection threshold, the first storage node executes the step of receiving the detection response message sent by the second storage node according to the second time period until the detection response message is received within the second time period or the number of rapid detections exceeds the detection threshold. Receiving the detection response message sent by the second storage node according to the second time period is the processing procedure in the above step 302, and the above step 302 has already described this processing procedure in detail, and the embodiment of the present application will not be repeated here.

[0106] Specifically, if the detection response message is received within the second time period, the first storage node determines that the detection result is a successful detection. If the number of rapid detections exceeds the rapid detection number threshold, the first storage node executes the following step 602. The specific processing process of step 602 is detailed in the following embodiment.

[0107] In an exemplary embodiment, after the network process of the first storage node is started, the first storage node determines the second storage node that needs to establish a network connection or rebuild a network connection based on the network configuration information. The first storage node performs a quick detection to determine whether the physical link between the first storage node and the second storage node is normal. When the physical link is normal, the first storage node establishes a network connection with the second storage node. Otherwise, when the physical link is abnormal, the first storage node fails to establish a network connection with the second storage node, which is an invalid operation. Therefore, in the case where the network connection with the second storage node does not exist or is abnormal, the present application provides a network detection method in a quick detection mode, such as Figure 5 shown. Figure 5 The flowchart of a network detection method in a fast detection mode in one embodiment includes:

[0108] Step 501: Send a detection request message to a second storage node.

[0109] Step 502: Try to receive a detection response message from the second storage node every 1 ms.

[0110] Step 503, determine whether a probe response message is received within 1 ms. If a probe response message is received, execute step 506. If no probe response message is received, execute step 504.

[0111] Step 504, update the fast detection times, and determine whether the updated fast detection times exceed the fast detection times threshold. If the updated fast detection times exceed the fast detection times threshold, execute step 505; if the updated fast detection times do not exceed the fast detection times threshold, execute step 502.

[0112] Step 505: determine that the initial detection result is a detection failure.

[0113] Step 506: Determine whether the detection result is successful.

[0114] When the physical link between the first storage node and the second storage node is normal, a detection response message can usually be received in one attempt. The network process startup usually occurs when the cluster is just being deployed. At this time, the physical link is expected to be normal. By sending a detection request message once and reducing the second time period, the detection can be completed quickly, thereby quickly establishing a network connection.

[0115] In this embodiment, if no detection response message is received within the second time period and the updated rapid detection times do not exceed the rapid detection times threshold, the detection response message continues to be received, thereby improving the success rate of the network detection method.

[0116] In an exemplary embodiment, if the number of rapid detections exceeds the rapid detection threshold, a normal mode network detection method needs to be executed. Figure 6 As shown, after step 404 is executed, the specific processing process of the network detection method further includes steps 602 to 604. Among them:

[0117] Step 602: If the number of rapid detections exceeds the rapid detection threshold, it is determined that the initial detection result is a failure.

[0118] In implementation, if the updated fast detection times exceed the fast detection times threshold, the first storage node determines that the initial detection result is a failure.

[0119] Specifically, when the updated number of fast detection times exceeds the fast detection times threshold, the first storage node ends the fast detection mode and determines that the initial detection result corresponding to the fast detection mode is a failure.

[0120] In an exemplary embodiment, the number of fast detections after the update is 1001 times, and the threshold number of fast detections is 1000 times. The first storage node determines that the number of fast detections after the update exceeds the threshold number of fast detections. If the number of fast detections after the update exceeds the threshold number of fast detections, the first storage node ends the fast detection mode and determines that the initial detection result corresponding to the fast detection mode is a failure.

[0121] Step 604: Send a detection request message to the second storage node according to the first time period, and update the initial detection result to obtain the detection result.

[0122] In implementation, a first time period is pre-set in the first storage node. The first storage node continuously sends a detection request message to the second storage node according to the first time period, and updates the initial detection result to obtain the detection result.

[0123] Specifically, when the initial detection result corresponding to the quick detection mode is a failure, the first storage node performs network detection in a normal detection mode. Specifically, a third time period and a fourth time period are pre-set in the first storage node. The first storage node sends a detection request message to the second storage node according to the first time period, and attempts to receive a detection response message based on the third time period. The first storage node determines whether the detection response message is received within the fourth time period, and obtains a first judgment result. Then, the first storage node updates the initial detection result according to the first judgment result, and obtains a detection result. Among them, the network detection process of the normal detection mode is similar to the processing process of the following steps 702 to 708 and steps 802 to 808, and the embodiments of the present application will not be repeated here.

[0124] In this embodiment, when the number of rapid detection times exceeds the rapid detection times threshold, a detection request message is sent to the second storage node according to the first time period, the normal detection mode is started, and the success rate of the network detection method is improved.

[0125] In an exemplary embodiment, before increasing the first time period, it is necessary to first determine whether the network interaction condition is met. Figure 7 As shown, before step 204 is executed, the specific processing process of the network detection method also includes steps 702 to 708. Among them:

[0126] Step 702: If the network connection is normal, send a detection request message to the second storage node based on the first time period, and receive a detection response message sent by the second storage node according to a third time period.

[0127] In implementation, if the network connection with the second storage node is normal, the first storage node sends a detection request message to the second storage node according to a first time period. Then, the first storage node attempts to receive a detection response message sent by the second storage node according to a third time period.

[0128] Specifically, a first time period and a third time period are pre-set in the first storage node. If the network connection is normal, the first storage node sends a detection request message to the second storage node at a time interval corresponding to the first time period. For example, if the first time period is 100ms, the first storage node sends a detection request message every 100ms. When the physical link between the first storage node and the second storage node is normal, the detection request message will reach the second storage node through the physical link. The second storage node receives the detection request message and sends a detection response message to the first storage node. The first storage node attempts to receive the detection response message sent by the second storage node at a time interval corresponding to the preset third time period. For example, the third time period is 50ms. The first storage node attempts to receive the detection response message sent by the second storage node every 50ms.

[0129] In an exemplary embodiment, if the network connection is normal, the first storage node performs a regular detection of the physical link between the first storage node and the second storage node to ensure that the data transmission between the first storage node and the second storage node is normal. If the network connection is normal and there is no data transmission with the second storage node, the first storage node sends a detection request message to the second storage node at a time interval corresponding to the first time period. Then, the first storage node attempts to receive a detection response message sent by the second storage node at a time interval corresponding to a third time period.

[0130] Optionally, the first time period can be but is not limited to being set to 100ms, and the third time period can be but is not limited to being set to 50ms, determined according to normal detection requirements. The embodiment of the present application does not limit the first time period and the third time period.

[0131] Step 704: Determine whether a detection response message sent by the second storage node is received within a fourth time period, and obtain a first determination result.

[0132] In implementation, a fourth time period is preset in the first storage node. The first storage node determines whether a detection response message sent by the second storage node is received within the fourth time period, obtains a first determination result, and determines whether the network interaction condition is met based on the first determination result.

[0133] Specifically, the fourth time period is set to 1 minute. The first storage node determines whether the detection response message sent by the second storage node is received within 1 minute. If the detection response message is received within 1 minute, the first storage node determines that the first judgment result is that the detection response message is received within the fourth time period. If the detection response message is not received within 1 minute, the first storage node determines that the first judgment result is that if the detection response message is received within 1 minute, the first storage node determines that the first judgment result is that the detection response message is not received within the fourth time period.

[0134] Optionally, the fourth time period can be set to, but not limited to, 1 minute or 2 minutes, determined according to normal detection requirements. The embodiment of the present application does not limit the fourth time period.

[0135] Step 706: If the first determination result is that a detection response message is received within the fourth time period, it is determined that the network interaction condition is not met, and the detection result is determined to be a detection success.

[0136] The first storage node is pre-set with a network interaction condition, wherein the first judgment result is that a detection response message is received within a fourth time period.

[0137] In implementation, if the first judgment result is that the detection response message is received within the fourth time period, the first storage node determines that the network interaction condition is not met. Then, the first storage node determines that the detection result is a detection success, and determines that the physical link between the first storage node and the second storage node is normal.

[0138] In an exemplary embodiment, since the first storage node performs a regular detection of the physical link between the first storage node and the second storage node, when the detection result is successful, the first storage node determines that the network connection with the second storage node is normal, and performs data transmission with the second storage node normally.

[0139] Step 708: If the judgment result is that no detection response message is received within the fourth time period, it is determined that the network interaction condition is met.

[0140] In implementation, if the judgment result is that the detection response message is not received within the fourth time period, the first storage node determines that the network interaction condition is met. Then, the first storage node executes step 204. The specific processing process of step 204 has been specifically described in the above embodiment, and the embodiment of the present application will not be repeated here.

[0141] In this embodiment, if the network connection is normal, a detection request message is sent according to the first time period, and it is determined whether a detection response message sent by the second storage node is received within the fourth time period to obtain a first judgment result. Then, it is determined whether the network interaction condition is met according to the first judgment result, so as to facilitate the subsequent execution of the network detection method.

[0142] In an exemplary embodiment, Figure 8 As shown, the specific processing process of step 204 includes steps 802 to 808. Among them:

[0143] Step 802, increase the first time period to twice the current first time period to obtain an increased first time period, and increase the third time period to twice the current third time period to obtain an increased third time period.

[0144] The increasing rule is to increase the first time period to twice the current first time period, and to increase the third time period to twice the current third time period.

[0145] In implementation, the first storage node increases the first time period to twice the current first time period to obtain an increased first time period. At the same time, the first storage node increases the third time period to twice the current third time period to obtain an increased third time period.

[0146] Specifically, a first time period threshold and a third time period threshold are set in the first storage node. The first storage node determines whether the first time period after being increased by two times exceeds the first time period threshold. If the first time period after being increased by two times does not exceed the first time period threshold, the first storage node increases the first time period to two times the current first time period to obtain the increased first time period. If the first time period after being increased by two times exceeds the first time period threshold, the first storage node updates the first time period to the first time period threshold. The first storage node determines whether the third time period after being increased by two times exceeds the third time period threshold. If the third time period after being increased by two times does not exceed the third time period threshold, the first storage node increases the third time period to two times the current third time period to obtain the increased third time period. If the third time period after being increased by two times exceeds the third time period threshold, the first storage node updates the third time period to the third time period threshold.

[0147] For example, the first time period is 100ms, and the first time period threshold is 1000ms. The third time period is 50ms, and the third time period threshold is 500ms. The first storage node determines that the first time period 200ms after being doubled does not exceed the first time period threshold 1000ms, and the first storage node increases the first time period 100ms to twice the current first time period, and obtains the increased first time period 200ms. The first storage node determines that the third time period 100ms after being doubled does not exceed the third time period threshold 500ms, and the first storage node increases the third time period 50ms to twice the current third time period, and obtains the increased third time period 100ms.

[0148] For example, the first time period is 800ms, and the first time period threshold is 1000ms. The third time period is 400ms, and the third time period threshold is 500ms. The first storage node determines that the first time period 1600ms after being doubled exceeds the first time period threshold of 1000ms, and the first storage node updates the first time period to 1000ms. The first storage node determines that the third time period 800ms after being doubled exceeds the third time period threshold of 500ms, and the first storage node updates the third time period to 500ms.

[0149] Optionally, the first time period threshold may be, but is not limited to, set to 1000 ms, and the third time period may be, but is not limited to, set to 500 ms. The embodiment of the present application does not limit the first time period threshold and the third time period threshold.

[0150] Step 804, updating the normal detection times, and determining whether the normal detection times exceed a preset normal detection times threshold.

[0151] In implementation, the first storage node is pre-set with a normal detection number, which is pre-set to 0. The first storage node updates the normal detection number, and then determines whether the updated normal detection number exceeds a normal detection number threshold.

[0152] Specifically, the first storage node adds the normal detection times and 1 to obtain the updated normal detection times. Then, the first storage node determines whether the updated normal detection times exceed the preset normal detection times threshold. If the updated normal detection times exceed the preset normal detection times threshold, the first storage node determines that the detection result is a detection failure, and determines that the physical link between the first storage node and the second storage node is abnormal. If the updated normal detection times do not exceed the normal detection times threshold, step 804 is executed.

[0153] For example, the threshold value of the number of normal detections is 5 times, and the number of normal detections is also 5 times. The first storage node adds the number of normal detections of 5 times and 1 to obtain an updated number of normal detections of 6 times. Then, the first storage node determines that the updated number of normal detections of 6 times exceeds the threshold value of the number of normal detections of 5 times, and the first storage node determines that the detection result is a detection failure, and determines that the physical link between the first storage node and the second storage node is abnormal. The first storage node closes the connection with the second storage node. Then, the first storage node determines that there is no network connection with the second storage node, and executes the above step 202 to re-establish the connection with the second storage node.

[0154] Optionally, the normal detection times threshold may be set to 5 times or 6 times, according to normal detection requirements. The embodiment of the present application does not limit the normal detection times threshold.

[0155] Step 806: If the normal detection times do not exceed the detection times threshold, send a detection request message to the second storage node according to the increased first time period, and receive a detection response message sent by the second storage node according to the increased third time period.

[0156] In implementation, if the number of normal detections does not exceed the detection number threshold, the first storage node sends a detection request message to the second storage node according to the increased first time period to detect again whether the physical link between the first storage node and the second storage node is normal. Then, the first storage node attempts to receive a detection response message sent by the second storage node according to the increased third time period.

[0157] Specifically, the first storage node sends a detection request message to the second storage node at a time interval corresponding to the increased first time period. For example, if the increased first time period is 200ms, the first storage node sends a detection request message to the second storage node every 200ms. When the physical link between the first storage node and the second storage node is normal, the detection request message will reach the second storage node through the physical link. The second storage node receives the detection request message and sends a detection response message to the first storage node. The first storage node attempts to receive the detection response message sent by the second storage node at a time interval corresponding to the increased third time period. For example, the increased third time period is 100ms. The first storage node attempts to receive the detection response message sent by the second storage node every 100ms.

[0158] Step 808, determining whether a detection response message sent by the second storage node is received within a fourth time period, obtaining a second determination result, and determining a detection result based on the second determination result.

[0159] In implementation, the first storage node determines whether a detection response message sent by the second storage node is received within the fourth time period to obtain a second determination result. Then, the first storage node determines the detection result according to the second determination result.

[0160] Specifically, the fourth time period is set to 1 minute. The first storage node determines whether the detection response message sent by the second storage node is received within 1 minute. If the detection response message is received within 1 minute, the first storage node determines that the second judgment result is that the detection response message is received within the fourth time period. If the detection response message is not received within 1 minute, the first storage node determines that the second judgment result is that the detection response message is not received within the fourth time period. Then, the first storage node determines the detection result according to the second judgment result.

[0161] In this embodiment, if the network connection is normal, the first time period is increased to obtain an increased first time period, and a detection request message is sent based on the increased first time period, thereby reducing the number of detection request messages and reducing the pressure on the distributed storage system.

[0162] In an exemplary embodiment, Fig. 9 As shown, the specific processing process of determining the detection result based on the second judgment result in step 808 includes steps 902 to 904. Among them:

[0163] Step 902: If the second determination result is that a detection response message is received within a fourth time period, the detection result is determined to be a detection success.

[0164] In implementation, if the second judgment result is that a detection response message fed back by the second storage node is received within the fourth time period, the first storage node determines that the detection result is a detection success. Then, the first storage node determines that the physical link between the first storage node and the second storage node is normal, and performs data transmission with the second storage node normally.

[0165] Step 904, if the second judgment result is that no detection response message is received within the fourth time period, execute the step of increasing the first time period to twice the current first time period to obtain the increased first time period, until a detection response message is received within the fourth time period or the number of normal detections exceeds the normal detection number threshold, and determine the detection result.

[0166] In implementation, if the second judgment result is that no detection response message is received within the fourth time period, the first storage node continues to execute the above step 802 until a detection response message is received within the fourth time period or the number of normal detections exceeds the normal detection number threshold. Among them, the specific processing process of step 802 has been described in detail in the above steps, and the embodiments of the present application will not be repeated here. If a detection response message is received within the fourth time period, the first storage node determines that the detection result is a successful detection. If the number of normal detections exceeds the normal detection number threshold, the first storage node determines that the detection result is a detection failure.

[0167] In an exemplary embodiment, Fig.10 FIG. 1 is a flow chart of a network detection method in a normal detection mode in an embodiment. Fig.10 As shown, the normal network detection method includes:

[0168] Step 1001, obtaining a first time period threshold and a first time period.

[0169] Step 1002: Send a detection request message to a second storage node according to a first time period.

[0170] Step 1003: Try to receive a detection response message according to a third time period, where the third time period is half of the first time period.

[0171] Step 1004, determining whether a probe response message is received within the fourth time period. If a probe response message is received within the fourth time period, executing step 1009. If no probe response message is received, executing step 1005.

[0172] Step 1005, update the normal detection times, and determine whether the updated normal detection times exceed the normal detection times threshold. If the updated normal detection times exceed the normal detection times threshold, execute step 1010. If the updated normal detection times do not exceed the normal detection times threshold, execute step 1006.

[0173] Step 1006: the first time period is increased to twice the current first time period to obtain an increased first time period, and the third time period is increased to twice the current third time period to obtain an increased third time period.

[0174] Step 1007, determine whether the increased first time period exceeds the first time period threshold. If the first time period exceeds the first time period threshold, execute step 1008. If the first time period does not exceed the first time period threshold, execute step 1002 according to the increased first time period.

[0175] Step 1008, updating the first time period to the first time period threshold, and updating the third time period to the third time period threshold, and executing step 1002 according to the updated first time period.

[0176] Step 1009: Determine whether the detection result is successful.

[0177] Step 1010: determine that the detection result is a detection failure, and determine that the physical link is faulty.

[0178] In this embodiment, the detection result is determined by the second judgment result, and it is clarified whether the physical link between the storage nodes is normal, which facilitates the subsequent establishment of the network connection between the storage nodes.

[0179] In an exemplary embodiment, Fig.11 FIG. 1 is a flow chart of a network detection method in another embodiment. Fig.11 As shown, the network detection method includes:

[0180] Step 1101, start the network process.

[0181] Step 1102, execute the rapid detection mode to obtain the initial detection result of the rapid detection mode.

[0182] Step 1103, determine whether the initial detection result is a successful detection. If the initial detection result is a successful detection, execute step 1106. If the initial detection result is a failed detection, execute step 1104.

[0183] Step 1104, executing the normal detection mode to obtain the detection result of the normal detection mode.

[0184] Step 1105, determine whether the detection result is a detection success. If the detection result is a detection success, execute step 1106. If the detection result is a detection failure, execute step 1104.

[0185] Step 1106: Establish a network connection with the second storage node.

[0186] Step 1107, monitor whether the network connection is running normally. If it is running normally, then end the execution of the network detection method. If it is running abnormally, then execute step 1108.

[0187] Step 1108, determine whether there is a successful message transmission. If there is a successful message transmission, execute step 1107. If there is no successful message transmission, execute step 1109.

[0188] Step 1109, executing the normal detection mode to obtain the detection result of the normal detection mode.

[0189] Step 1110, determine whether the detection result is a detection success. If the detection result is a detection success, execute step 1107. If the detection result is a detection failure, execute step 1111.

[0190] Step 1111, determine whether the physical link is faulty. If the physical link is faulty, execute step 1112. If the physical link is not faulty, execute step 1107.

[0191] Step 1112 , close the network connection with the second storage node, and execute step 1102 .

[0192] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows.
