Description

Device detection method, device and communication device

This application claims the priority of the Chinese patent application filed on October 13, 2020 with the application number 202011093314.2 and the title of the invention is "A device detection method, device and communication device", the entire contents of which are incorporated by reference in in this application.

technical field

The present application relates to the field of communications, and in particular, to a device detection method, apparatus, and communication device.

Background technique

In a distributed network, in order to obtain the status of each network device in the network in time, the heartbeat detection method is usually used to detect whether each device in the network fails. Specifically, the heartbeat detection method means that a device periodically sends a heartbeat data packet to another device, and then determines whether the receiving end device is in a normal state according to the response data packet situation fed back by the other device. For example, as shown in Figure 1, device 1 periodically sends a heartbeat data packet to device 2, and then waits for device 2 to feed back a response data packet. If device 1 does not receive a response data packet sent by device 2 within a preset time period, the device 1 will determine that the device 2 is faulty, and an alarm message needs to be reported at this time.

In practice, technicians found that when the heartbeat detection method is used to detect the status of the device, the system may misjudge due to network fluctuations. For example, when the network fluctuates, the network line may be on and off, which will cause the sending end device or router, such as the heartbeat data packet sent by device 1 periodically, to lose packets, or "probabilistic packet loss", which leads to the receiving end. Device 2 will not send a response data packet. At this time, device 1 can only determine that device 2 is faulty, but in fact, it may be that the transmission line between device 1 and device 2 is faulty, but device 2 itself is not faulty. Therefore, the actual state of the device cannot be accurately detected by using the heartbeat detection method, and the accuracy rate is low.

Detailed ways

In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present application, and to make the above-mentioned purposes, features and advantages of the embodiments of the present application more clearly understood, the following describes the technical solutions in the embodiments of the present application with reference to the accompanying drawings. The program is described in further detail.

Before describing the technical solutions of the embodiments of the present application, the application scenarios of the embodiments of the present application are first described with reference to the accompanying drawings.

The technical solution of the present application can be applied to a distributed network, and the network can be a centralized network or a decentralized network, such as applied to a smart home environment. Among them, the so-called decentralization is a concept relative to centralization. Every device in the decentralized network is equal, and there is no master device and slave device. For a centralized network, the master device generally sends heartbeat packets to other slave devices and waits for other slave devices to feed back response packets, while in a decentralized network, devices send heartbeat packets and responses to each other. data pack.

For example, as shown in FIG. 2 , a schematic structural diagram of a decentralized network provided in this embodiment. The network includes at least three electronic devices, such as device 1 , device 2 and device 3 . In addition, other electronic devices, such as switches, routers, and servers, may also be included, and this embodiment does not limit the type and number of electronic devices included in the network.

Optionally, any one of the devices 1 to 3 may be a terminal device, and the terminal device may be a portable device, such as a smart terminal, a mobile phone, a notebook computer, a tablet computer, a personal computer , PC), personal digital assistant (PDA), foldable terminal, vehicle terminal, wearable device with wireless communication function (such as smart watch or bracelet), user device (user device) or user device (user device) equipment, UE), and augmented reality (AR) or virtual reality (virtual reality, VR) equipment, etc. In addition, the terminal device may also be a smart home device, such as audio, air conditioners, refrigerators, TVs, washing machines, and water heaters deployed in indoor homes. The embodiments of this application do not limit the specific device form of the terminal device. . In addition, the above-mentioned various terminal devices include, but are not limited to, those equipped with Apple (IOS), Android (Android), Microsoft (Microsoft) or other operating systems.

In addition, any one of the devices 1 to 3 may also be a network device, such as a switch, a gateway, a server, etc., which is not limited in this embodiment.

It should be noted that, if the above-mentioned device is a terminal device, the communication between the device and the device can be transmitted through a wireless network, such as WiFi; if the above-mentioned device is a network device, the communication between the device and the device can be through the Internet, such as fiber optic transmission. This application does not limit the specific transmission medium between devices.

This embodiment provides a device detection method, which can be applied to the above-mentioned distributed network, and can detect the abnormal response response caused by probabilistic packet loss when the network fluctuates.

Wherein, a possible situation of the probabilistic packet loss is that due to the instability of the line when the network fluctuates, the phenomenon of the network link being on and off occurs, resulting in the loss of heartbeat packets during the link transmission process. In this case, the receiving end device may be in a normal state, can receive heartbeat data packets, and feed back a response message.

As shown in Figure 3, the method includes the following steps:

101: When the first device detects that the response response fed back by the second device times out, acquire historical heartbeat data synchronized by the first device within a first time period.

The historical heartbeat data includes responses to the heartbeat data packets from the other two devices detected by each of the first device, the second device, and the third device. Specifically, the historical heartbeat data includes at least the following three parts:

1. The historical heartbeat data of the first device, including: the second device detected by the first device in the first time period, and/or the response of the third device to the heartbeat data packet sent by itself (the first device) ;

2. The historical heartbeat data of the second device, including: the first device detected by the second device in the first time period, and/or the response of the third device to the heartbeat data packet sent by itself (the second device) ;

3. The historical heartbeat data of the third device, including: the first device detected by the third device in the first time period, and/or the response of the second device to the heartbeat data packet sent by itself (the third device) .

The above-mentioned historical heartbeat data of the first device is obtained from statistics by the first device, and the historical heartbeat data of the second device and the historical heartbeat data of the third device are actively reported to the first device through their respective devices, and the first device obtains after receiving them respectively. .

Specifically, taking the historical heartbeat data of the first device as an example, an implementation manner of acquiring the historical heartbeat data of the first device is: the first device periodically sends the heartbeat to the second device and the third device in the network For data packets, the sending cycle and sending range can be customized. For example, if the sending cycle is set to 1s (seconds), the first device sends a heartbeat data packet or heartbeat message to each other device every 1s. When the second device and the third device receive the heartbeat data packet sent from the first device, they will send a response to the first device, such as feeding back a response response data packet or response message, etc.; the first device will send Start timing after a heartbeat data packet, and determine whether a response response feedback from the second device and the third device is received within a preset time. The preset time can be customized.

If the first device receives a response sent by the second device or the third device (receiving end) within the preset time, it means that the response feedback of the receiving end has not timed out; if the response is received outside the preset time, Or if no response response is received, it means that the response feedback from the receiving end times out. Optionally, the response feedback timeout may also be referred to as abnormal heartbeat.

For example, device 1 sends a heartbeat message 1 to device 2 and device 3 respectively at time t1, then device 1 receives response message 1 fed back by device 2 at time t2, and receives the response message fed back by device 3 at time t3 2. If the time interval between t1 and t2 is within the preset time interval, device 1 records that the response response corresponding to the heartbeat message sent to device 2 at time t1 has not timed out; if the time interval between t1 and t3 is within the preset time interval Otherwise, or the response message 2 sent by the device 3 is not received within the preset time interval, the response time-out corresponding to the heartbeat message sent to the device 3 at time t1 is recorded.

Optionally, for the non-timed-out response response, the first device marks it as "0", and for the time-out response response, the first device marks it as "1". For the above device 2, the device 1 will mark the response to the heartbeat message 1 sent at time t1 as "0", and for the above device 3, device 1 will respond to the heartbeat message 1 sent at time t2. Marked as "1". It should be understood that the device 1 may also use other methods to mark the situation that the response response it receives has timed out or not, and the marking method adopted by the device 1 is not limited in this embodiment. In this embodiment, when it is detected that the response response of the second device times out, that is, when the heartbeat response is abnormal, a two-dimensional array of all "1"s is recorded.

Similarly, the second device also periodically sends heartbeat data packets to the first device and the third device, respectively, and records the response timeouts of the first device and the third device to form historical heartbeat data of the second device. The third device also periodically sends heartbeat data packets to the second device and the first device, respectively, and records the response timeout of the second device and the first device to form historical heartbeat data of the first device.

In addition, the historical heartbeat data can be refreshed regularly, such as storing historical heartbeat data at 1min (minute) intervals on each device side, or refreshing the local storage record every 1min, and updating the historical heartbeat data to the latest 1-2min Historical heartbeat data.

This embodiment takes the first device as an example. In the above step 101, when the first device detects that the response response fed back by the second device has timed out, it means that the first device and the second device are in normal communication, and the devices at both ends send and receive each other. Heartbeat data packet and response response, when the first device sends a heartbeat data packet to the second device at a certain time, but does not receive the response packet fed back by the second device within a preset time (for example, 1s), the first device will The device confirms that the current response response fed back by the second device times out, and starts the method of step 101 .

102: Determine the reason for the timeout of the response response of the second device according to the response response situation detected by each device in the historical heartbeat data, the reasons include: the second device is faulty, or the second device is faulty. The transmission link between the device and the first device fails.

Specifically, the first condition and the second condition can be used to determine whether the cause of the timeout is a failure of the device itself or a failure of a transmission link between devices.

The first condition is: the total number N2 of response timeouts corresponding to the second device is the largest, and the total number N3 of response timeouts corresponding to the third device is greater than 0. Expressed as: N2>N1, N2>N3, and N3>0.

The second condition is: the total number N1 of response timeouts corresponding to the first device is greater than 0, the total number N2 of response timeouts corresponding to the second device is greater than 0, and the total number N3 of response timeouts corresponding to the third device equal to 0. Expressed in expressions: N1>0, N2>0, and N3=0.

Wherein, N1 represents the total number of response timeouts of the first device within the first time period, N2 represents the total number of response timeouts of the second device within the first time period, and N3 represents the third The total number of response timeouts of the device within the first time period. The first time period can be set freely, for example, set to 30s, 60s, 90s, 120s, etc., which is not limited in this embodiment.

In the present embodiment, several possible implementations in which the first device determines the cause of the failure of the second device according to the historical heartbeat data are described below.

first embodiment

In this embodiment, it is assumed that the frequency of each device sending heartbeat data packets is 1 per second, the period is 1 second, the first time period is 60s, and the preset time is 1s, that is, device 1 sends a heartbeat data packet After detecting that the time interval for the response of the receiving end to not time out is 1s, within a detection period of 60s, if device 1 continuously receives 60 response packets sent by device 2, it is assumed that device 2 feeds back the response packet time to device 1. Very short, such as the feedback response at the millisecond level, in the 61s, within the detection period (the first time period) from the 1s to the 60s, the device 1 detects the response of the device 2 to the heartbeat data packet sent by the device 1. The number of response timeouts is 0, that is, the number of abnormal heartbeats is 0. Similarly, if device 1 only receives 4 response packets from device 3 that meet the preset time interval of 1 s within 60s, it marks 4 "0"s, and the feedback responses of the remaining 56 heartbeat packets are If the timeout is exceeded, that is, 56 "1"s are marked, then device 1 counts the response response of device 3 in the past 60s, and the number of response response timeouts is 56, that is, the number of abnormal heartbeats is 56.

Optionally, the number of abnormal heartbeats can be represented by the letter "a", then _a12 represents the abnormal number of heartbeats (or response response situation) of device 2 counted by device 1 in the first time period, and _a13 represents that device 1 is in The number of abnormal heartbeats of the device 3 counted in the first time period, and the historical heartbeat data of the device 2 and the device 3 counted by the device 1 in the first time period is {a ₁₂ , a ₁₃ }. In the above example, a ₁₂ =0, a ₁₃ =56, then the historical heartbeat data of device 1 counted by device 1 in 60s is {0, 56}.

Similarly, the historical heartbeat data of the second device may be represented as {a ₂₁ , a ₂₃ }, and the historical heartbeat data of the third device may be represented as {a ₃₁ , a ₃₂ }. Wherein, a ₂₁ represents the number of times the abnormal heartbeat occurred in the device 1 counted by the device 2 in the first time period, a ₂₃ represents the number of times the abnormal heartbeat occurred in the device 3 counted by the device 2 in the first time period, a ₃₁ Represents the number of times the abnormal heartbeat occurs to the device 1 as counted by the device 3 in the first time period, and a ₃₂ represents the number of times the abnormal heartbeat of the device 2 occurs as counted by the device 3 in the first time period.

At this time, all the historical heartbeat data obtained by device 1 in the first time period from device 1 to device 3 are as follows:

And, the device 1 stores these historical heartbeat data in the local storage medium of the device 1 .

In addition, the above method further includes: the first device sends the historical heartbeat data collected by the first device in the first time period to the second device and the third device, respectively. The second device sends its historical heartbeat data collected in the first time period to the first device and the third device respectively. The third device sends its historical heartbeat data collected in the first time period to the first device and the second device respectively. Thus, the first device, the second device, and the third device all obtain the historical heartbeat data counted by the other two devices, respectively.

When it is detected that the state of the second device in the network is abnormal, the data synchronization module of the first device obtains the historical heartbeat data of the first device, and simultaneously obtains the historical heartbeat data from other devices in the network. The heartbeat data of a ₁₂ is set as the default data.

The above-mentioned reason for analyzing the feedback timeout of the second device according to the historical heartbeat data of the first device, the second device and the third device in the first time period obtained by the first device is specifically:

First, determine the total number N1 of response timeouts of the first device, the second device, and the third device within the first time period according to the response status detected by each device. The total number of response timeouts is the cumulative abnormal heartbeat number N1, and the cumulative abnormal heartbeat number N1 is the sum of the abnormal heartbeat times detected by all devices.

For example, the cumulative number of abnormal heartbeats of device 1 is N1, and N1=a ₁₂ +a ₁₃ +a ₂₁ +a ₃₁ ,

The cumulative number of abnormal heartbeats of device 2 is N2, and N2=a ₁₂ +a ₂₁ +a ₂₃ +a ₃₂ ,

The cumulative number of abnormal heartbeats of the device 3 is N3, and N3=a ₁₃ +a ₂₃ +a ₃₁ +a ₃₂ .

If N1, N2, and N3 are different, and N2>N1>N3, N3>0, or, N2>N1, N2>N3, and N3>0, then the first condition above is satisfied, then it is determined that the reason for the timeout is the The second device (ie Device 2) has failed. In this embodiment, the device with the most accumulated heartbeat timeouts (or abnormal times) is determined as the failed device.

Similarly, if N1>N2>N3, and N3>0, or, N1>N2, N1>N3, and N3>0, it is determined that the first device (ie, device 1) is faulty. If N3>N2>N1, and N3>0, or, N3>N2, N3>N1, and N3>0, it is determined that the third device (ie, device 3) is faulty.

For example, when device 1 detects that device 2 is abnormal, the historical heartbeat data obtained from device 1 to device 3 in the first time period is:

Then N1=6+3+3+5=17, N2=6+3+0+0=9, N3=3+0+0+5=8, ie N1>N2>N3, then it is determined that the equipment 1 is faulty.

If N1=N2>0, and N3=0, the above-mentioned second condition is satisfied, and it can be determined that the reason for the timeout is the transmission chain between the second device (ie device 2) and the first device (ie device 1) Road failure.

The method provided in this embodiment uses the historical heartbeat data detected by two peripheral devices and the historical heartbeat data obtained by the device itself to detect a device in an abnormal state, and determines the number of timeouts by comparing the number of timeouts of each device in the past period of time. The reason for the failure is the failure of the device itself, or the link failure caused by probabilistic packet loss. Since the obtained historical heartbeat data is the heartbeat timeout condition detected and reported by multiple devices, the global information is used to make decisions. For the detection of historical heartbeat data of a single device, the method improves the accuracy of device fault detection in a distributed network, thereby avoiding misjudgment caused by probabilistic packet loss in the case of network fluctuations.

In addition, in this method, each device in the distributed network periodically obtains the heartbeat timeout of other devices in the past period of time, and synchronizes the historical heartbeat data of these devices, thereby preparing for accurate detection in the event of a failure.

If a ₁₂ > 0, a ₂₁ > 0, and a ₃₂ > 0, the above first condition is satisfied, and it is determined that the device 2 is faulty; if a ₁₂ > 0, a ₂₁ > 0, and a ₃₂ =0, the above is satisfied The second condition is to determine that the link between device 1 and device 2 is faulty.

When a failure of device 2 is detected in this embodiment, the historical heartbeat data of device 3 is used to determine whether the failure belongs to device 2 itself or the transmission link between device 1 and device 2, thereby improving the performance of distributed networks in the network. The accuracy of fault detection in fluctuating scenarios.

third embodiment

This embodiment is similar to the aforementioned second possible embodiment, the difference is that in the historical heartbeat data acquired by the device 1, in addition to a ₁₂ , a ₂₁ , a ₃₂ of the second possible embodiment, it also includes a _23. The a ₃₁ represents the cumulative timeout times of the feedback response of the device 1 counted by the device 3 in the first time period. At this time, N1=a ₁₂ , N2=a ₂₁ , and N3=a ₃₂ +a ₂₃ , then the above steps 102. Determine whether the cause of the failure is the failure of the device 2 or the transmission link between the device 1 and the device 2 through the historical heartbeat data, and the determination method is as follows:

If a ₁₂ > 0, a ₂₁ > 0, and a ₃₂ + a ₂₃ > 0, the above first condition is satisfied, and it is determined that the equipment 2 is faulty; if a ₁₂ > 0, a ₂₁ > 0, and a ₃₂ +a ₂₃ =0, the above second condition is satisfied, and it is determined that the cause of the failure is that the link between the device 1 and the device 2 is faulty.

It should be noted that, according to the difference of the above-mentioned historical heartbeat data, other more or less judging methods may also be included, and this embodiment will not describe the above-mentioned specific judging methods one by one.
