Description

Technical Field

[0001] Embodiments of the present application relate to the technical field of local area networks, and in particular, to a multi-gateway dynamic hot standby method, device, equipment, and storage medium. Background Art

[0002] In the application scenario of smart home, there are more and more sub-devices in the home environment, resulting in a single gateway often being unable to manage all devices. Therefore, a multi-gateway architecture is adopted for management. Under the conventional multi-gateway architecture, different gateway devices under the same network cannot communicate directly. Even with a master-slave gateway architecture, the solution in the related art is to designate a certain device as the master gateway, and the rest are slave gateways.

[0003] In the case where the master gateway is abnormal and needs to be replaced with a new master gateway, the related solutions often involve manually modifying the configuration of the slave gateway to achieve the replacement of the master gateway, or presetting a replacement gateway device in the current gateway architecture to replace the master gateway when the master gateway is abnormal.

[0004] However, in the above methods, such as the manual modification method, it cannot achieve timely replacement, resulting in a poor user experience; while the method of presetting a replacement device cannot form a multi-gateway dynamic hot standby in the case of multiple gateway abnormalities (such as both the master gateway and the replacement gateway device are abnormal), and it is difficult to effectively provide a new master gateway for the network architecture. Summary of the Invention

[0005] Embodiments of the present application provide a multi-gateway dynamic hot standby method, device, equipment, and storage medium, which can achieve multi-gateway dynamic hot standby, timely select a slave gateway for replacement when the master gateway is abnormal, and reduce the impact caused by the abnormality of the master gateway.

[0006] In a first aspect, an embodiment of the present application provides a multi-gateway dynamic hot standby method, which is applied to a first gateway device in a multi-gateway architecture, and the first gateway device stores a first gateway list therein. The first gateway list stores at least the local identification information associated with the first gateway device, and the first gateway device broadcasts the first gateway list to other gateway devices in the multi-gateway architecture. The method includes:

[0007] Updating the first gateway list according to the received second gateway list broadcast by other gateway devices to obtain a third gateway list;

[0008] Determining whether there is first identification information associated with the first master gateway device in the third gateway list;

[0009] If there is first identification information in the third gateway list, establish a communication connection between the master and slave gateways with the first master gateway device;

[0010] When the first master gateway device is abnormal, select a target gateway device that meets the preset conditions from the third gateway list as the second master gateway device, and establish a communication connection between the master and slave gateways with the second master gateway device.

[0021] In this solution, multiple gateway devices in the same local area network back up each other. If the master gateway device is abnormal, multiple slave gateway devices will immediately elect the next master gateway device and resynchronize the data.

It can be understood that the specific embodiments described herein are only used to explain the embodiments of the present application, rather than limiting the embodiments of the present application. Additionally, it should be noted that for the sake of description, only parts related to the embodiments of the present application are shown in the accompanying drawings, rather than all structures.

It should be understood that such data can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and do not limit the number of objects. For example, the first object can be one or multiple. In the description of the specification and claims, "multiple" is expressed as the first. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally represents an "or" relationship between the associated objects before and after.

[0030] In a multi-gateway architecture constructed by multiple gateway devices, in this architecture, there is a gateway device serving as the main gateway and at least one network device serving as a slave gateway, such as Figure 1 shown Figure 1 It is a schematic diagram of a multi-gateway architecture in the related art. Among them, gateway device 101 is the main gateway in the architecture, and gateway devices 201-204 are all slave gateways in the architecture. In addition, in the figure, GW1 is used to identify the main gateway device, and GW2 is used to identify the slave gateway device.

[0031] The multi-gateway dynamic hot standby method provided by the embodiments of the present application can be applied to the above-mentioned gateway devices. In a multi-gateway architecture, each gateway device stores a gateway list, which is used to store the identification information of all gateway devices in the architecture, such as role type, IP address, system startup duration, etc. When initially accessing the network, the gateway device can join the local area network including the multi-gateway architecture as a slave gateway, and at least store the local identification information related to itself. After the gateway device accesses the network, it can broadcast the local identification information to other gateway devices in the local area network at regular intervals. Of course, the gateway device can also receive the identification information broadcast by other gateway devices.

[0032] In some embodiments, gateway devices of different role types in the architecture can broadcast messages at different broadcast intervals. For example, the broadcast interval of the master gateway device is 5s; for the slave gateway device that has joined the master gateway (i.e., a communication connection between the master gateway and the slave gateway is established), the corresponding broadcast interval is 5s, while for the slave gateway device that has not joined the master gateway, the corresponding broadcast interval is 1s.

[0033] The following is an illustration of applying the multi-gateway dynamic hot standby method in the first gateway device. The first gateway device can be a slave gateway device or a gateway device that has switched from a master gateway to a slave gateway. Corresponding to the first gateway device, a first gateway list is stored thereon, and the local identification information associated with the first gateway device is stored in the first gateway list.

[0034] Figure 2 It is a flowchart of the steps of the multi-gateway dynamic hot standby method provided by the embodiments of the present application. As shown in the figure, the multi-gateway dynamic hot standby method includes the following steps:

[0035] Step S210: Update the first gateway list according to the second gateway list broadcast by other gateway devices to obtain a third gateway list.

[0036] In the local area network, gateway devices broadcast messages to other gateway devices in the network at the predefined broadcast intervals in the devices, such as broadcasting the gateway list of the device in the local area network. Therefore, when the first gateway device receives the gateway list (i.e., the second gateway list) broadcast by other gateway devices, the first gateway device updates the first gateway list according to the second gateway list, thereby obtaining a third gateway list, that is, the updated gateway list.

[0037] For example, after the first gateway device obtains the second gateway list, it compares the first gateway list with the second gateway list and removes duplicates from the second gateway list, that is, deletes the overlapping parts between the first gateway list and the second gateway list, and then adds the remaining part of the second gateway list to the first gateway list to obtain the third gateway list. Therefore, the identification information of all gateway devices in the entire local area network, such as role type, IP address, system startup duration, etc., can be stored in the third gateway list.

[0038] Step S220: Determine whether there is first identification information associated with the first master gateway device in the third gateway list.

[0039] The first identification information can be used to indicate that the corresponding gateway device is the master gateway device. For example, it carries a first parameter item indicating the role type as the master gateway, so that the gateway device that parses the first identification information from the gateway list can learn that there is a master gateway device in the network.

[0040] After the first gateway device obtains the third gateway list, the first gateway device searches in the list to determine whether there is first identification information associated with the first master gateway device in the third gateway list, so as to determine whether there is a first master gateway device in the local area network. It should be noted that the first master gateway device can be a gateway device preset as the master gateway in the local area network.

[0041] It should be noted that the process of searching the third gateway list can be executed during the update process of the first gateway list. For example, while continuously updating the gateway list, the gateway device also continuously searches in the gateway list to determine whether there is a master gateway device in the local area network.

[0042] Step S230: If there is first identification information in the third gateway list, establish a communication connection between the master and slave gateways with the first master gateway device.

[0043] It can be understood that when there is first identification information in the third gateway list, it means that there is a first master gateway device in the local area network. Therefore, the first gateway device can obtain the IP address of the first master gateway device from the third gateway list to establish a communication connection between the master and slave gateways with the first master gateway device.

[0044] In an embodiment, the first gateway device sends a gateway join request to the first master gateway device according to the obtained IP address of the first master gateway device, such as sending it at a preset request interval, and of course, this request interval is less than the broadcast interval, such as set to 500 ms.

[0045] Moreover, the first gateway device is also set with a waiting period for determining whether to establish a connection. For example, within the waiting period, if the first gateway device receives a request response message from the first master gateway device corresponding to the join gateway request, the first gateway device will correspondingly record the connection status with the first master gateway device in the third gateway list, with the first master gateway device as the connected master gateway. For example, corresponding information can be recorded in the third gateway list to indicate the master-slave relationship between the current first master gateway device and the first gateway device. For example, a master gateway mark can be added to the third gateway list of the first gateway device to indicate the master gateway connected to the first gateway device.

[0046] It should be noted that the waiting period is longer than the request interval. Exemplarily, the waiting period can be set to 6 request intervals to facilitate waiting for the response (i.e., the request response message) from the first master gateway device. Moreover, within the waiting period, the first gateway device can continuously send join gateway requests at the request interval until it receives a response from the first master gateway device. Of course, for the request response message received after the waiting period expires, the first gateway device determines that the gateway joining fails.

[0047] The slave gateway device and the master gateway device communicate and connect with each other through information interaction, such as join gateway requests and request response messages, so as to ensure that the slave gateway device can be connected to the master gateway device.

[0048] Step S240: When the first master gateway device is abnormal, select a target gateway device that meets the preset conditions from the third gateway list as the second master gateway device, and establish a master-slave gateway communication connection with the second master gateway device.

[0049] There are various situations where the first master gateway device is abnormal, such as power failure, damage, and network connection interruption of the first master gateway device, resulting in the inability to interact with the slave gateway device. For example, if the slave gateway does not receive the broadcast or unicast message from the master gateway after multiple broadcast cycles, the slave gateway can determine that the master gateway is abnormal.

[0050] When the first master gateway device is abnormal, the first gateway device selects a target gateway device from the third gateway list as the second master gateway device. The target gateway device meets the preset conditions, such as taking the minimum system startup duration as the preset condition. Thus, the gateway device with the minimum system startup duration is found in the third gateway list as the target gateway device. Of course, in the case where the target gateway device is used as the second master gateway device, the first gateway device and other gateway devices within the local area network are all connected to the target gateway device.

[0051] It can be conceived that for other gateway devices in the local area network that do not meet the preset conditions, they wait for a new master gateway device (i.e., the second master gateway device) to broadcast the gateway list to update the locally stored gateway list, and send a gateway joining request to the second master gateway device to establish a connection.

[0052] Exemplarily, as Figure 3 shown, Figure 3 is a schematic diagram of a multi-gateway architecture after the master gateway is abnormal provided by an embodiment of the present application. In the figure, the gateway device 101 drops offline, that is, the communication connection between the master gateway and each slave gateway is interrupted (as indicated by the connection line and × in the figure to represent the communication connection interruption), and the remaining gateway devices 201-204 compete to select a latest master gateway (GW1 represents the master gateway device and GW2 represents the slave gateway device in the figure).

[0053] It can be understood that the gateway devices 201-204 respectively search the gateway lists stored locally in their own devices, and search for the device with the smallest system startup duration from them. For example, the gateway devices 201-204 all determine that the gateway device 202 is the device with the smallest startup time among all gateway devices except the offline gateway device 101. Therefore, the gateway device 202 is used as the latest master gateway, and the gateway devices 201 and 203 respectively establish a communication connection between the master and slave gateways with the gateway device 202 as the master gateway (the connection relationship indicated by the dotted line in the figure).

[0054] From the above solution, for multiple gateway devices in the same local area network, the above multi-gateway dynamic hot standby method is applied to form a dynamic backup of the multi-gateway devices. Thus, in the case of an abnormal master gateway device, a device can be re-selected from the remaining slave gateway devices as the master gateway for replacement, and the multi-gateway architecture can be quickly restored to normal operation, reducing the impact caused by the abnormal master gateway. In addition, this process does not require manual intervention for replacement, which can reduce labor costs, and there is no need to customize different firmware for the master gateway device and the slave gateway device, further saving R & D and maintenance costs.

[0055] In some embodiments, similarly, the local identification information also carries a first parameter item for identifying the role type, and the local identification information also carries a second parameter item for identifying the system startup duration.

[0056] The first gateway device acts as a slave gateway device and is connected to the first master gateway device. When the master gateway device is abnormal, if among all the slave gateway devices, the first gateway device has the minimum system startup duration as the gateway device, that is, when the first gateway device is the target gateway device, the first gateway device updates the local identification information recorded in the third gateway list, that is, changes the role type in the first parameter item from slave gateway to master gateway. After the first gateway device completes the update of the list, it broadcasts the updated third gateway list to other gateway devices within the multi-gateway architecture to inform other gateway devices within the architecture.

[0057] Similarly, for the case where other slave gateway devices act as target gateway devices, they also update the local gateway list and broadcast it. It should be noted that when a slave gateway device changes to a master gateway device, it can broadcast the updated gateway list at a faster frequency. For example, the timing broadcast interval is updated to 500 ms and lasts for 60 broadcast cycles, so that other gateway devices can receive the updated gateway list.

[0058] In the case of the master gateway device being abnormal, the first gateway device selects a gateway device as the new master gateway device by comparing the system durations corresponding to each gateway device stored in the gateway list, realizing the backup of the master gateway. Without human intervention, the multi-gateway architecture can resume working, reducing the impact caused by the abnormality of the master gateway.

[0059] In an embodiment, when the first master gateway device recovers from an abnormality, if a slave gateway device has been selected as the new master before its recovery, the two master gateways need to compete to select one as the master gateway device in the entire multi-gateway architecture. Here, taking the first gateway device as the new master gateway device (i.e., the second master gateway device) as an example for illustration.

[0060] As Figure 4 shown, the multi-gateway hot standby method applied to the first gateway device further includes the following steps:

[0061] Step S410: Obtain the number of first sub-gateway devices corresponding to the first master gateway device.

[0062] Step S420: Determine whether the number of second sub-gateway devices corresponding to the second master gateway device is less than the number of first sub-gateway devices.

[0063] Step S430: If the number of second sub-gateway devices is less than the number of first sub-gateway devices, update the role type to slave gateway and broadcast the updated third gateway list to other gateway devices within the multi-gateway architecture.

[0064] It can be understood that as the main gateway device, it will record the slave gateway devices connected to it and the corresponding quantity (i.e., the number of sub - gateways). For example, it stores them in the local gateway list. Therefore, when the first main gateway device recovers from an anomaly, such as power - off recovery, network re - connection recovery and other anomaly recovery situations, after the second main gateway device receives the gateway list broadcast by the first main gateway device, it can obtain the first sub - gateway quantity corresponding to the first main gateway device from it, and by comparing the first sub - gateway quantity and the second sub - gateway quantity, it can judge the gateway device acting as the main gateway.

[0065] In the case where the second sub - gateway quantity is less than the first sub - gateway quantity, the second main gateway device updates the role type in the first parameter item recorded in the third gateway list to a slave gateway, and broadcasts the updated gateway list to other gateway devices. It should be noted that after the first gateway device is restored to a slave gateway device, it still establishes a master - slave gateway communication connection with the first main gateway device that has recovered from the anomaly. And the slave gateway devices connected to the second main network device also establish a master - slave gateway communication connection with the first main gateway device.

[0066] It can be imagined that if the second sub - gateway quantity is greater than the first sub - gateway quantity, the first main gateway device updates the gateway list stored locally, updates the role type to a slave gateway, and broadcasts the updated gateway list to other gateway devices.

[0067] For the anomaly recovery of the main gateway device, the two main gateways also need to compete to determine the final gateway device acting as the main gateway, so as to maintain the one - master - multiple - slaves layout in the multi - gateway architecture, which is convenient for the management of multi - gateway devices.

[0068] It should be noted that for the situation of the first main gateway device recovering from an anomaly, by comparing the sub - gateway quantities of the first main gateway device and the second main gateway device, as well as the system startup durations of the two devices, to determine the gateway device acting as the main gateway finally. For example, for the case where the first sub - gateway quantity is equal to the second sub - gateway quantity, it is determined whether the second system startup duration corresponding to the second main gateway device is greater than the first system startup duration corresponding to the first main gateway device.

[0069] If the second system startup duration is greater than the first system startup duration, the second main gateway device updates the role type to a slave gateway, and broadcasts the updated gateway list to other gateway devices. It should be noted that when the second main gateway device is restored to a slave gateway, it establishes a connection with the current main gateway, that is, the first main gateway device. For example, taking the first main gateway device as the main gateway and sending a join - gateway request to it.

[0070] It is conceivable that if the startup duration of the second system is less than that of the first system, the first main gateway device updates its role type to a slave gateway, broadcasts the updated gateway list to other gateway devices, and establishes a connection with the second main gateway device. For example, it uses the second main gateway device as the main gateway and sends a gateway join request to it.

[0071] In some embodiments, the role type of the gateway device serves as the first parameter item in the identification information, while the system startup duration of the gateway device serves as the second parameter item in the identification information. Therefore, the first gateway device searches for the identification information corresponding to each gateway device in its third gateway list to determine whether there is a gateway device with the role type of main gateway.

[0072] The first identification information is the identification information corresponding to the main gateway with the role type. When the first gateway device detects that there are multiple first identification information in the third gateway list, it obtains the number of sub - gateways of the first main gateway device corresponding to each first identification information. The first gateway device determines the target main gateway device based on the number of sub - gateways of multiple first main gateway devices. For example, it uses the first main gateway device with the largest number of sub - gateways as the target main gateway device. It should be noted that after determining the target main gateway device, the other first main gateway devices update their role types to slave gateways, thus establishing a connection with the target main gateway device.

[0073] Of course, for the case where the number of sub - gateways of multiple first main gateway devices is the same, the first gateway device obtains the second parameter item corresponding to each first main gateway device to determine the target main gateway device from the system startup duration recorded in the second parameter item. For example, it uses the first main gateway device with the shortest system startup duration as the target main gateway device.

[0074] Therefore, for the situation where multiple main gateway devices appear in the local area network, not only do the main gateway devices compete with each other, but other slave gateway devices also determine the connected main gateway device according to the identification information of the main gateway device, thereby increasing the number of sub - gateways connected to the main gateway device, so as to better select the gateway device as the main gateway.

[0075] It should be noted that the gateway device can dynamically adjust its own role type, that is, the gateway device can act as either a slave gateway or a main gateway to meet the competition among multiple gateways. When the gateway device switches from a slave gateway to a main gateway, the gateway device will regularly broadcast its own gateway list, and also receive the gateway lists of the connected slave gateway devices to regularly update the locally stored gateway list. In addition, the gateway device acting as the main gateway also sends a request response message to the sender (i.e., the slave gateway device) according to the received gateway join request, so that the main gateway device and the slave gateway device establish a connection.

[0076] Figure 5 This is a schematic diagram of the multi-gateway dynamic hot standby device provided by the embodiments of the present application. This device is used to execute the multi-gateway dynamic hot standby method provided by the above embodiments, and has the corresponding functional modules and beneficial effects for executing the method.
