[0002] As the Internet Protocol (IP) bearer network evolves towards the goal of cloud-network converged infrastructure, the logic of the IP bearer network is becoming more and more complex. Any random failure may have a chain reaction on the IP bearer network. Therefore, chaos engineering can be used to inject various types of failures into the IP bearer network to discover hidden risks and conduct reliability assessments. However, before using chaos engineering to inject failures, it is necessary to predefine the size of the explosion radius corresponding to the failure so that the impact range of the failure can be controlled manually. The explosion radius is used to characterize the impact range of the failure on the bearer network.

[0084] 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.

[0085] Figure 1 A schematic diagram of an application scenario for information acquisition provided in an embodiment of the present application. Figure 1 As shown, the scenario includes an offset state information collection server 100, a fault injection server 200, and a device 300 in the bearer network. The offset state information collection server 100 transmits data with the fault injection server 200 and the device 300 in the bearer network respectively through the network, and the fault injection server 200 and the device 300 in the bearer network transmit data through the network. The fault injection server 200 is used to inject a fault into the device 300 in the bearer network, and determine trigger information according to the fault generation information sent by the device 300 in the bearer network, and send the trigger information to the offset state information collection server 100. The offset state information collection server 100 is used to generate request information according to the trigger information, and send the request information to the device 300 in the bearer network to receive the offset state information sent by the device 300 in the bearer network.

[0086] Currently, as the IP bearer network evolves towards the ultimate goal of cloud-network converged infrastructure, for example, the interconnection of virtual and real devices and resource sharing, the intercommunication of new and old network architectures and routing solutions, the management of different cloud networks, the expansion and contraction of cloud networks and open source, the IP bearer network has become more and more complex, and any random failure may have a chain reaction on the IP bearer network. Therefore, it is extremely important to pre-discover risks and evaluate the reliability of the evolving IP bearer network. Chaos engineering can be used to randomly inject various types of faults into the IP bearer network to discover and resolve potential risks, which can effectively solve such problems. Before injecting faults in chaos engineering, it is necessary to pre-define the explosion radius that characterizes the impact range of the fault on the bearer network, so that the impact range of the fault can be considered controlled.

[0087] In traditional technology, the size of the explosion radius is usually judged based on theoretical knowledge and historical experience of experts. However, the granularity of the explosion radius determined by this method is large and the accuracy is low. Alternatively, by injecting faults into devices in the IP bearer network, such as routers, and manually logging into each device and typing in fault generation commands, after the fault is generated, the artificially controlled information collection server obtains the operating status of each device, thereby determining the impact range of the injected fault on the bearer network based on the operating status of each device. However, for large-scale networks, this method requires artificial injection of fault generation commands and manually controls the collection of device operating status, which has the problem of low efficiency in collecting device operating status, resulting in low efficiency in determining the explosion radius. Based on this, there is a problem of low timeliness in determining the explosion radius of the fault on the bearer network in traditional technology.

[0088] Based on the above-mentioned traditional technology, an embodiment of the present application provides an information acquisition method, which receives trigger information sent by a fault injection server. Since the trigger information is determined based on the fault generation information sent by the device in the bearer network, the offset status information collection server can obtain the offset status information generated by the device based on the status indicator information of adjacent time nodes according to the trigger information. Compared with the traditional technology, there is no need to manually control the offset status information collection server to obtain the offset status information when the fault generation is determined. It can trigger the operation of obtaining the offset status information generated by the device according to the trigger information, thereby saving the time for obtaining the offset status information and improving the efficiency of obtaining the offset status information, thereby improving the timeliness of determining the explosion radius of the fault on the bearer network according to the obtained offset status information.

[0089] It should be noted that the beneficial effects brought about by the embodiments of the present application or the technical problems solved are not limited to this one, but may also include other implicit or related problems. For details, please refer to the description of the following embodiments.

[0090] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0091] In one embodiment, Figure 2 As shown, a method for obtaining information is provided, which is applied to Figure 1 The offset status information collection server in the example is used as an example to illustrate, including the following steps:

[0092] S201, receiving trigger information sent by a fault injection server; the trigger information is determined according to fault generation information sent by a device in the bearer network.

[0093] Among them, the fault injection server randomly injects various preset faults into the devices in the bearer network in a human-controlled manner, thereby causing damage to the devices in the bearer network to test the operating status of the devices under the preset fault conditions. Optionally, the fault injection server can be a server, or the fault injection server can also be a terminal, etc. In this embodiment, after the preset fault is injected into the device in the bearer network by the fault injection server, the device in the bearer network will send fault generation information after the fault is generated. The above trigger information can be generated according to the fault generation information after the fault injection server receives the fault generation information sent by the device in the bearer network. Optionally, the devices in the bearer network can include routers, storage devices, switches, servers, etc. As an optional implementation method, the bearer network can include one device or multiple devices. This embodiment does not limit this. Therefore, the fault injection server can inject different faults into different devices according to actual needs, so that the fault injection server can generate trigger information for different devices according to the different fault generation information received.

[0094] As an optional implementation, the trigger information may include the fault group identifier of the injected device and the time information when the device generates the fault based on the fault group identifier. The fault group identifier is identification information used to distinguish the fault type. It can be understood that different numbers can be used as identifiers of different faults, and the faults can be divided into different fault groups in advance according to the types of each fault. Faults corresponding to different fault group identifiers can be injected into different devices according to actual needs. Optionally, one fault group can include one fault, or one fault group can also include multiple faults. Optionally, the fault injection server can inject a group of fault groups into a device, or the fault injection server can also inject multiple groups of fault groups into a device.

[0095] It can be understood that when a device generates a certain fault, the device can record the identifier of the generated fault and the generation time of the fault, and determine the identifier of the generated fault, the fault group identifier corresponding to the fault, and the generation time of the fault as the fault generation information, and send the fault generation information to the fault injection server, so that the offset status information collection server can receive the trigger information generated by the fault injection server based on the fault generation information.

[0096] In this embodiment, when the fault injection server receives the fault generation information sent by the device, it can compare the corresponding fault in the received fault generation information with the fault of the injected device, and determine whether the faults of all injected devices are generated based on the comparison result; if the faults of all injected devices are generated, the trigger information is determined based on the fault generation information, and the determined trigger information may include the fault group identifier of the injected device and the time information when the device generates the fault based on the fault group identifier.

[0097] S202, acquiring the offset state information of the device according to the trigger information; the offset state information is generated by the device based on the state indicator information of adjacent time nodes.

[0098] Among them, the offset state information refers to the difference information of the state indicator information corresponding to the device at different time nodes. According to the offset state information, the change of the operating state of the device injected with the fault can be determined. In this embodiment, the offset state information can be obtained according to the preset state indicator The corresponding state indicator information of the device at adjacent time nodes is compared, and the two sets of state indicator information are determined according to the comparison result. It can be understood that different faults may correspond to different state indicator information. Injecting different types of faults into the device may also affect different state information. Optionally, the state indicator information may include the throughput, storage capacity, utilization rate of the device, and the delay, jitter, packet loss and other information of the device's data transmission.

[0099] In this embodiment, when the offset status information collection server receives the trigger information, it can respond to the trigger information, thereby triggering the operation of obtaining the offset status information. Optionally, the offset status information collection server can send an acquisition message of the offset status information to the device in the bearer network through the network. When the device in the bearer network receives the acquisition message sent by the offset status information collection server, it can obtain the status indicator information corresponding to the device at adjacent time nodes according to the operating status of the device, obtain the offset status information according to the status indicator information of the adjacent time nodes, and send it to the offset status information collection server through the network, so that the offset status information collection server can obtain the offset status information of the device.

[0100] In the above information acquisition method, the offset status information collection server receives the trigger information sent by the fault injection server. Since the trigger information is determined based on the fault generation information sent by the device in the bearer network, the offset status information collection server can obtain the offset status information generated by the device based on the status indicator information of adjacent time nodes according to the trigger information. Compared with the traditional technology, there is no need to manually control the offset status information collection server to obtain the offset status information when the fault generation is determined. It can trigger the operation of obtaining the offset status information generated by the device according to the trigger information, thereby saving the time for obtaining the offset status information and improving the efficiency of obtaining the offset status information, thereby improving the timeliness of determining the explosion radius of the fault on the bearer network according to the obtained offset status information.

[0101] In the above scenario of obtaining the offset state information of the device according to the trigger information, the offset state information collection server can send a request message to the device upon receiving the trigger information, so as to obtain the offset state information sent by the device. Figure 3 As shown, the above S202 includes:

[0102] S301, when trigger information is received, a request message is sent to the device; the request message is used to instruct the device to collect and send offset status information.

[0103] Among them, the request information refers to the request information that the offset status information collection server sends to the device to obtain the offset status information, so that the device can collect the operating status of the corresponding device according to the request message after receiving the request information, obtain the offset status information according to the operating status of the device and send it to the offset status information collection server.

[0104] As an optional implementation, the request information may include at least one of the following: a status indicator set identifier of the device, a status indicator set corresponding to the status indicator set identifier, a preset time interval corresponding to the status indicator set, and a preset time interval corresponding to the status indicator set.

[0105] It should be noted that the operating status of the equipment affected by different faults may be different. Therefore, for different faults, it is necessary to collect status indicator information corresponding to different faults. In this embodiment, the corresponding indicator set identifier can be determined in advance according to the fault type of the injected device, so that the corresponding status indicator set identifier and the status indicator set corresponding to the device are sent to the device through the request message sent. Exemplarily, if the bearer network includes multiple devices, the status indicator set identifier corresponding to each device can be determined in advance according to the fault group injected into each device, so that the determined status indicator set identifier and the status indicator set corresponding to the status indicator set identifier are sent to the corresponding device through the request message.

[0106] It should be noted that in order to ensure the timeliness and effectiveness of the obtained offset status information, the time for the device to collect the offset status information can be limited. Therefore, the time interval for obtaining the offset status information and the time interval for obtaining it can be included in the request message. It can be understood that different status indicator sets may correspond to different time intervals and time intervals. Therefore, the corresponding preset time interval and preset time interval can be determined according to the status indicator set corresponding to each device. For example, if it is necessary to collect the offset status information of the injected fault device at night, the preset time interval can be set to 20:00-21:00, and the preset time interval can be set to 5s, so that the preset time interval and time interval can be sent to the corresponding device through the request message.

[0107] In this embodiment, the offset status information collection server can respond to the trigger information when it receives the trigger information, thereby generating a request message based on the device's status indicator set identifier, the status indicator set corresponding to the status indicator set identifier, the preset time interval corresponding to the status indicator set, and the preset time interval corresponding to the status indicator set under the triggering of the trigger information, and sending the request message to the device through the network, thereby receiving the offset status information collected and sent by the device based on the request message. It should be noted that when the offset status information collection server receives the trigger information, it can generate a request message in real time based on the trigger information.

[0108] S302: receiving offset status information sent by the device based on the request information.

[0109] In this embodiment, the offset state information collection server can receive the offset state information sent by the device in the bearer network under the instruction of the request information, and collect the offset state information generated during the operation of the device. Exemplarily, if the state indicator set included in the request message includes the throughput of the device and the delay of data transmission, the preset time interval is 20:00-21:00, and the preset time interval is 5s, then the device can obtain the throughput and data transmission delay information of the device every 5s from 20:00 to 21:00 based on the request message, and calculate the difference between the throughput and data transmission delay information corresponding to two adjacent time nodes, and use the difference as the initial offset state information, so as to send all the initial offset state information from 20:00 to 21:00 as offset state information to the offset state information collection server.

[0110] In this embodiment, when the offset status information collection server receives trigger information, it can trigger the offset status information collection server to send request information to the device, so that the device can collect and send the offset status information according to the instructions of the request information. Since the offset status information collection server can trigger the sending of a request message for the offset status information to the device according to the trigger information, it avoids artificial control of the offset status information collection server sending a request message to increase the time for obtaining information, thereby saving the time for the receiving device to send the offset status information based on the request information, and improving the efficiency of obtaining the offset status information of the device.

[0111] Based on the above acquisition of the device offset status information, in order to further ensure the impact of the device failure in the bearer network, the blast radius of the failure on the bearer network can also be determined based on the offset status information. In one embodiment, the above method also includes: determining the blast radius of the bearer network based on the offset status information.

[0112] Among them, the explosion radius of the bearer network refers to the range of the impact on the bearer network caused by the equipment in the bearer network when a fault occurs. In this embodiment, the offset state information collection server can send the offset state information to the offset state information analysis module for analysis after receiving the offset state information, so as to obtain the range of the impact of the fault injected into the device on the bearer network according to the offset state information, that is, determine the explosion radius of the bearer network. It can be understood that if the offset state information indicates that the deviation of the operating state of the device after the fault is generated is larger, it means that the explosion radius is larger; if the offset state information indicates that the deviation of the operating state of the device after the fault is generated is smaller, it means that the explosion radius is smaller.

[0113] In this embodiment, the explosion radius of the bearer network is determined based on the offset status information. Since the offset status information is obtained after the offset status information collection server sends request information to the device according to the trigger information, compared with the traditional technology, the offset status information can be obtained more quickly, and the efficiency of obtaining the offset status information is improved, thereby improving the timeliness of determining the explosion radius of the bearer network based on the offset status information.

[0114] In one embodiment, a method for obtaining information is also provided. Figure 1 Taking the fault injection server in as an example, the method includes: sending trigger information to the offset status information collection server; the trigger information is determined according to the fault generation information sent by the device in the bearer network, and the trigger information is used to instruct the offset status information collection server to obtain the offset status information of the device, and the offset status information is generated by the device based on the status indicator information of adjacent time nodes.

[0115] Among them, the offset status information collection server is a device for collecting offset status information corresponding to the equipment of the bearer network. Optionally, the offset status information collection server can be a server, or the offset status information collection server can also be a terminal. In this embodiment, the trigger information can be that the fault injection server injects a preset fault into the equipment in the bearer network, thereby receiving the fault generation information sent by the equipment in the bearer network after the fault is generated, and is generated according to the fault generation information. Optionally, the equipment of the bearer network may include routers, storage devices, switches, servers, etc. The bearer network may include one device or multiple devices. This embodiment does not limit this. Therefore, the fault injection server can inject different faults into different devices according to actual needs, thereby determining the trigger information according to different fault generation information.

[0116] As an optional implementation, the trigger information may include the fault group identifier of the injected device and the time information when the device generates the fault based on the fault group identifier. The fault group identifier is identification information used to distinguish the fault type. It can be understood that different numbers can be used as identifiers of different faults, and the faults can be divided into different fault groups in advance according to the type of each fault. Faults corresponding to different fault group identifiers can be injected into different devices according to actual needs. Optionally, a fault group can include one fault, or a group leader group can also include multiple faults. Optionally, the fault injection server can inject a group of fault groups into a device, or the fault injection server can also inject multiple groups of fault groups into a device.

[0117] It can be understood that when a fault is generated in the device, the device can record the identification of the generated fault and the generation time of the fault, and determine the identification of the generated fault, the fault group identification corresponding to the fault and the generation time of the fault as the fault generation information, and send the fault generation information to the fault injection server. The fault injection server can determine the trigger information based on the received fault generation information, and send the trigger information to the offset status information collection server.

[0118] In this embodiment, the fault injection server can, when receiving the fault generation information sent by the device, compare the corresponding fault in the received fault generation information with the fault of the injected device, and determine whether the faults of all injected devices are generated based on the comparison result; if the faults of all injected devices are generated, determine the trigger information based on the fault generation information, and send the trigger information to the offset status information collection server, which can instruct the offset status information collection server to obtain the offset status information generated by the device based on the status indicator information of adjacent time nodes.

[0119] In the above-mentioned information acquisition method, the fault injection server can instruct the offset status information collection server to obtain the offset status information generated by the device based on the status indicator information of adjacent time nodes by sending trigger information determined according to the fault generation information sent by the device in the bearer network to the offset status information collection server. Since the offset status information collection server can be triggered to obtain the offset status information according to the trigger information, compared with traditional technologies, there is no need for manual control of the offset status information collection server to obtain the offset status information, which can save time for obtaining the offset status information, thereby improving the timeliness of the explosion radius determined according to the offset status information.

[0120] In the scenario where the fault injection server determines the trigger information based on the fault generation information sent by the device in the bearer network, the fault injection server can inject the fault into the device by sending a fault mapping table to the device. In one embodiment, the method further includes: sending a fault mapping table to the device; the fault mapping table includes at least one of the following: a fault group identifier, fault description information, a fault generation configuration command, and current time information.

[0121] Among them, the fault mapping table can be used to represent the corresponding relationship between the fault group and the device. Optionally, the fault group and the device can be a one-to-one relationship, or a many-to-one relationship. The corresponding relationship between the fault group and the device can be set according to actual needs. In this embodiment, the fault mapping table may include a fault group identifier, fault description information, a fault generation configuration command, and current time information. Among them, the fault group identifier can be used to distinguish different types of faults. The fault description information may include the specific phenomenon, severity, and affected business scope corresponding to each fault. The fault generation configuration command refers to the generation program corresponding to each fault. The corresponding fault can be generated by running the generation program. The current time information refers to the time when the fault injection server injects the fault into the device.

[0122] As an optional implementation, the fault injection server may send the fault mapping table to the device based on the identification number of the device.

[0123] In this embodiment, the corresponding relationship between the device identification and the fault mapping table corresponding to the device may be pre-stored in the fault injection server, so that the corresponding fault mapping table may be sent to the device according to the device identification number.

[0124] In this embodiment, by sending a fault mapping table to the device, the fault group identifier, fault description information, fault generation configuration command and previous time information can be sent to the device, so that the device can generate a corresponding fault according to the fault generation configuration command, and then collect the corresponding fault generation information after the fault is generated and send it to the fault injection server.

[0125] In the above scenario of sending trigger information to the offset state information collection server, the fault injection server can determine the trigger information by receiving the fault generation information sent by the device, and then send the trigger information to the offset state information collection server. Figure 4 As shown, the above method also includes:

[0126] S401, receiving fault generation information sent by a device.

[0127] The fault generation information is determined based on the faults that have been generated and the generation time of the generated faults after the device generates the fault information according to the fault generation configuration command. According to the fault generation information, it can be determined whether all the faults injected into the device are generated and the generation time.

[0128] In this embodiment, the fault injection server may receive the fault generation information sent by the device when the device determines the fault generation information as the fault generation information according to the generation time corresponding to a certain generation fault, the identifier of the generation fault, and the fault group identifier corresponding to the generation fault.

[0129] S402: Determine trigger information according to the fault generation information.

[0130] In this embodiment, the fault injection server may determine trigger information according to the received fault generation information. Optionally, the determined trigger information may include the fault group identifier of the device injected by the fault injection server and the time information when the device generates the fault based on the fault group identifier.

[0131] As an optional implementation, the fault injection server can, when receiving the fault generation information sent by the device, compare the corresponding fault in the received fault generation information with the fault of the injected device, and determine whether the faults of all injected devices are generated based on the comparison result; if the faults of all injected devices are generated, determine the trigger information based on the fault generation information.

[0132] In this embodiment, the fault injection server can determine the trigger information based on the fault generation information by receiving the fault generation information sent by the device. Since the fault generation information includes the generated fault and the shopping time, the fault injection server can accurately determine the trigger information based on the fault generation information, thereby improving the accuracy of the determined trigger information, and further improving the accuracy of the offset status information collection server triggered by the trigger information to collect the offset status information.

[0133] In one embodiment, Figure 5 As shown, a method for obtaining information is also provided, which is applied to Figure 1 The following steps are used as an example to illustrate the device in the bearer network:

[0134] S501, receiving request information sent by a deviation status information collection server; the request information is determined by the deviation status information collection server according to trigger information sent by a received fault injection server, and the trigger information is determined according to fault generation information sent by a device.

[0135] The request information refers to the request information that the offset status information collection server sends to the device to obtain the offset status information. It should be noted that the operating status of the device affected by different faults may be different. Therefore, for different faults, it is necessary to collect the status indicator information corresponding to different faults. The offset status information collection server can generate different request information based on different status indicator information and send the corresponding request information to the device. For example, if the bearer network includes multiple devices, the offset status information collection server needs to determine different status indicator information based on the fault group identifier in each device, generate different request information, and then send the corresponding request information to each device.

[0136] Among them, the trigger information can be determined by the fault injection server according to the fault generation information sent by the device. Optionally, the trigger information may include the fault group identifier pre-injected into the device and the time information when the device generates the fault based on the fault group identifier. The fault group identifier is identification information used to distinguish the fault type, and the time information of generating the fault refers to the time when the fault in the device is generated.

[0137] It can be understood that when the device receives a fault injected by a fault injection server, it can determine the generated fault identifier, the fault group identifier corresponding to the generated fault, and the generation time of the fault as fault generation information and send it to the fault injection server when the fault is generated. When the fault injection server determines that all injected faults are generated, it can determine the trigger information based on the fault generation information and send the trigger information to the offset status information collection server, so that the offset status information collection server can be triggered and generate request information, so that the device can receive the request information sent by the offset status information collection server.

[0138] In this embodiment, the device may receive the request information sent by the deviation status information collection server when the deviation status information collection server receives the trigger information and responds to the trigger information and generates the request information according to the trigger information.

[0139] S502: Generate offset status information of the device based on the status indicator information of adjacent time nodes according to the request information.

[0140] Optionally, the request information may include at least one of the following items: a status indicator set identifier of the device, a status indicator set corresponding to the status indicator set identifier, a preset time interval corresponding to the status indicator set, and a preset time interval corresponding to the status indicator set. It can be understood that if any information in the request information is different, the offset status information generated by the device will also be different.

[0141] In this embodiment, the device can collect the status indicator information corresponding to adjacent time nodes after a time interval based on the status indicator set identifier and the status indicator set in the request information, and calculate the difference between the status indicator information corresponding to the adjacent time nodes, and use the difference as the offset status information.

[0142] As an optional implementation, the difference between the status indicator information corresponding to any two adjacent time nodes within the time interval can be used as the initial offset status information, thereby generating the offset status information of the device from multiple initial offset status information within the preset time interval. Exemplarily, if the status indicator set included in the request message includes the throughput of the device and the delay of data transmission, the preset time interval is 20:00-21:00, and the preset time interval is 5s, then the device can obtain the throughput and data transmission delay information of the device every 5s from 20:00 to 21:00 based on the request message, and calculate the difference between the throughput and data transmission delay information corresponding to two adjacent time nodes, and use the difference as the initial offset status information, thereby using all the initial offset status information from 20:00 to 21:00 as the offset status information.

[0143] S503: Send the offset status information to the offset status information collection server.

[0144] In this embodiment, when the device generates the offset status information, it may send the generated offset status information to the offset status information collection server through the network.

[0145] In the above-mentioned information acquisition method, the device in the bearer network receives the request information sent by the offset status information collection server. Since the request information is determined by the offset status information collection server based on the trigger information sent by the received fault injection server, and the trigger information can quickly trigger the offset status information collection server to generate the request information, the time for the device to receive the request information is saved, so that the device can quickly generate the offset status information of the device based on the status indicator information of the adjacent time nodes, and send the offset status information to the offset status information collection server, thereby improving the efficiency of the offset status information collection server in obtaining the offset status information; in addition, since the trigger information is determined based on the fault generation information sent by the device, the determined trigger information can fully characterize the generation of faults in the device.

[0146] In the above scenario of receiving the request information sent by the offset status information collection server, the device needs to send the fault generation information to the fault injection server. The detailed process of the device sending the fault generation information to the fault injection server is described below. Figure 6 As shown, before the above S501, the above method further includes:

[0147] S601: Receive a fault mapping table sent by a fault injection server.

[0148] Among them, the fault mapping table can be used to represent the correspondence between fault groups and devices. Optionally, the fault groups and devices can be a one-to-one relationship, or a many-to-one relationship. The correspondence between fault groups and devices can be set according to actual needs.

[0149] Optionally, the fault mapping table includes at least one of the following items: a fault group identifier corresponding to the device, a fault generation configuration command, fault description information, and current time information. Among them, the fault group identifier can be used to distinguish different types of faults, the fault description information can include the specific phenomenon, severity, and affected business scope corresponding to each fault, the fault generation configuration command refers to the generation program corresponding to each fault, and the corresponding fault can be generated by running the generation program, and the current time information refers to the time when the fault injection server injects the fault into the device.

[0150] In this embodiment, the device can receive a fault mapping table sent by a fault injection server according to the identification number of the device. Optionally, the fault mapping table received by the device may include a fault group identifier and a fault generation configuration command, fault description information, and current time information corresponding to the fault group identifier, indicating that the fault injection server injects a group of faults into the device; or, the fault mapping table received by the device may also include multiple fault group identifiers and a fault generation configuration command, fault description information, and current time information corresponding to each fault group identifier, indicating that the fault injection server injects multiple groups of faults into the device.

[0151] S602: Determine fault generation information according to the fault mapping table.

[0152] In this embodiment, the device can determine the injected fault according to the corresponding fault group identifier in the received fault mapping table, and generate the corresponding fault by running the fault generation configuration command, so that when a fault is generated, the fault generation information is determined according to the generation time of the generated fault, the identifier of the generated fault, and the identifier of the fault group to which the generated fault belongs.

[0153] S603: Send the fault generation information to the fault injection server.

[0154] In this embodiment, the device can send the determined fault generation information to the fault injection server through the network. Optionally, the device can send the fault generation information corresponding to each generated fault to the fault injection server when the fault is generated. Alternatively, the device can also send the fault generation information corresponding to all generated faults to the fault injection server when each fault in the corresponding fault group identifier is generated.

[0155] In this embodiment, the device in the bearer network can determine the fault generation information according to the fault mapping table by receiving the fault mapping table sent by the fault injection server, and thus can send the fault generation information to the fault injection server. Since the fault generation information is generated according to the injected fault mapping table, there is no need to manually log in to the device to write a program to generate the fault, thereby improving the efficiency of generating faults.

[0156] The specific process of the device determining the offset state information according to the request information is described in detail below. Figure 7 As shown, the above S502 includes:

[0157] S701, determining a state indicator set, a time interval, and a time interval according to request information.

[0158] Among them, the status indicator set in the request information refers to the set of indicators corresponding to the fault group injected by each device. For example, when a fault is generated in the device, the throughput, utilization, storage capacity of the device during operation when the fault is generated, and the delay, jitter, packet loss and other status information of the device transmitting data can be collected, and the collected status information is used as the information corresponding to the status indicator. The time interval and time interval in the request information can be set according to actual needs. For example, the time interval can be 0:00-06:00, and the time interval can be 5s.

[0159] In this embodiment, the device can parse the received request information to obtain the status indicator set, time interval and time interval carried in the request information. It can be understood that if the bearer network includes multiple devices and the fault type injected into each device is different, the status indicator set included in the request information sent by the offset status information collection server to each device is also different.

[0160] S702: Determine first status indicator information of an indicator in a status indicator set at a first time node.

[0161] Among them, the first time node refers to the moment when the device obtains the operating status of the device for the first time, and the first status indicator information refers to the operating status of the device obtained according to the status indicator set at the first time node. Optionally, if the status indicator set includes 1 indicator, the first status indicator information includes status indicator information corresponding to the indicator; if the status indicator set includes 3 indicators, the first status indicator information includes status indicator information corresponding to each of the 3 indicators.

[0162] In this embodiment, the device can determine the operating state that meets the indicators in the status indicator set from the operating state of the device corresponding to the first time node based on the indicators in the status indicator set, thereby determining the operating state that meets the indicators in the status indicator set as the first status indicator information.

[0163] S703: Determine a second time node adjacent to the first time node according to the time interval and the time interval, and obtain second state indicator information of the indicator at the second time node.

[0164] Among them, the second time node refers to the moment when the device re-acquires the new operating status of the device after a time interval after acquiring the first status indicator information. The second status indicator information refers to the operating status of the device obtained according to the status indicator set at the second time node. It can be understood that the quantity and type of the second status indicator information are the same as those of the first status indicator information.

[0165] In this embodiment, after obtaining the first status indicator information, the device can, after a time interval, re-obtain the operating status of the device corresponding to the second time node, and determine therefrom the operating status that meets the indicators in the status indicator set, thereby determining the operating status that meets the indicators in the status indicator set as the second status indicator information.

[0166] It is understandable that, within a time interval, multiple time nodes can be determined according to the time interval, and the device can also use the above second time node as a new first time node, and determine a new second time node according to the time interval, and obtain the new second state indicator information of the indicator at the new second time node, thereby determining all indicator information within the time interval. For example, if the time interval is 08:00-09:00 and the time interval is 10s, it can be determined that the time interval includes 10 time nodes, so that 10 indicator information can be obtained.

[0167] S704: Determine offset state information according to the first state indicator information and the second state indicator information.

[0168] In this embodiment, the first state indicator information and the second state indicator information can be compared, and the comparison result can be determined as the offset state information. For example, if the indicator in the state indicator set is the utilization rate of the device, the first state indicator information obtained is 60%, and the second state indicator information is 55%, then the offset state information can be determined to be the utilization rate of the device is 5%.

[0169] Optionally, initial offset state information may be determined based on indicator information corresponding to every two adjacent time nodes, thereby determining the mean of each initial offset state information as the offset state information; or, the sum of each initial offset state information may be determined as the offset state information.

[0170] In this embodiment, the device determines the status indicator set, time interval and time interval according to the request information, and can determine the first status indicator information of the indicator in the status indicator set at the first time node, and determine the second time node adjacent to the first time node according to the time interval and time interval, and obtain the second status indicator information of the indicator at the second time node. Since the device can accurately determine the status indicator information corresponding to each time node according to the time interval, it can accurately determine the offset status information according to the first status indicator information and the second status indicator information, and further can accurately determine the explosion radius of the fault on the bearer network according to the offset status information, thereby improving the precision and accuracy of the determined explosion radius.

[0171] In order to facilitate the understanding of those skilled in the art, the following Figure 8 The information acquisition method provided by this application is described in detail.
