Meanwhile, each device shadow component specifically manages the shadow of which device, which can depend on the ID of the device and the number of device shadow components in the cluster. According to the consistent hashing algorithm, when the device is determined and the number of device shadow components in the cluster is determined, a uniquely determined device shadow component can be obtained. When the number of device shadow components in the cluster changes, the maintained relationship can be recalculated, and there is no single-point risk.

[0033] The embodiments of the present specification provide a communication method, device, equipment and medium of a distributed device registration center.

[0034] Generally, the Internet of Things device connects the Internet of Things platform using TCP, MQTT, CoAP and other protocols. Using these protocols requires the device to establish a long connection with the platform. When the platform accesses the device quantity increases, the Internet of Things platform supporting only a single node will inevitably cause performance bottlenecks. If the server of the deployed platform is down or the platform service fails, the entire platform will be unavailable.

[0035] In the face of the problem of increasing the number of device connections, the general solution of the current industry is to deploy multiple network connection instances. The device is artificially divided into connection platform instances. This solution can solve the concurrent pressure of increasing the number of connections, but the path of connecting the device to the platform is fixed and cannot reduce the risk of local downtime because the device connection cannot be automatically migrated after a certain node failure.

[0036] In order for those skilled in the art to better understand the technical solutions in the specification, the technical solutions in the specification will be clearly and completely described below in conjunction with the drawings in the specification. Obviously, the described embodiments are only part of the embodiments of the specification, not all embodiments. Based on the embodiments of the specification, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the specification.

[0037] Figure 1 A flowchart of a communication method of a distributed device registration center provided for one or more embodiments of the specification, which can be executed by a communication system of the distributed device registration center. Some input parameters or intermediate results in the flow allow manual intervention to adjust to help improve accuracy.

[0038] The distributed device registration center of the embodiments of the specification can include four-layer load balancing software, network components, device shadow components, and seven-layer load balancing software. The method flow steps of the embodiments of the specification are as follows:

[0039] S102, when receiving a network connection request of a specified Internet of Things device, randomly forwarding the network connection request to any specified network component through a round-robin strategy of the four-layer load balancing software.

[0040] In the embodiments of the specification, the specified Internet of Things device can include smart home devices, industrial sensors, smart cars, smart cameras, and manufacturing robots. When the specified Internet of Things device is an industrial sensor, users can use the connected sensor device to collect data of their factory equipment and monitor potential problems of the assembly line. Internet of Things sensors can help improve operational visibility, maintenance planning, and logistics by monitoring equipment and specific resource consumption rates.

[0041] In the embodiments of the present application, the network connection request can be a request for a specified IoT device to connect to an IoT platform. The network component can be used for the connection between the platform and the specified IoT device, and the maintained state information is persisted in the database, which is updated when the specified IoT device is disconnected or reconnected.

[0042] In the embodiments of the present application, the network connection request is forwarded to the specified network component through the round-robin strategy of the four-layer load balancing software. Since the four-layer load balancing software uses the round-robin strategy to distribute requests, each network component is equally replaceable, and there is no single point risk.

[0043] It should be noted that the four-layer load balancing software can be IP+port-based load balancing: on the basis of three-layer load balancing, the IP address of the three-layer is published, and then the port number of the four-layer is added. The target address and port in the message, and the network component selection method set by the load balancing device, determine the final selection of the specified network component.

[0044] S104, processing the network connection request through the specified network component, and establishing a connection between the specified IoT device and the registration center to generate networking information of the specified IoT device.

[0045] In the embodiments of the present application, when the network component processes the network connection request, the association between the specified IoT device and the specified network component can be recorded in the database, and the networking information can include the association between the specified IoT device and the specified network component, and the metadata of the specified IoT device.

[0046] S106, sending the networking information of the specified IoT device and the real-time device data of the specified IoT device to the specified device shadow component, so that the networking information and the real-time device data are managed by the specified device shadow component, and when a user issues a control request for the specified IoT device, the control request is randomly forwarded to any device shadow component through the round-robin strategy of the seven-layer load balancing software. If it is determined that the any device shadow component is the specified device shadow component, the control request is sent to the specified network component through the networking information and the real-time device data of the specified device shadow component, and the control request is sent to the specified IoT device through the specified network component.

[0047] In the embodiments of the present application, the device shadow component is a virtual mapping (which can be understood as a json document) of the specified Internet of Things device in the cloud, which is used to record the recent state and expected state of the specified Internet of Things device, and the cloud can control the state of the specified Internet of Things device through the device shadow component. The seven-layer load balancing software can be a virtual URL or host IP-based load balancing: on the basis of four-layer load balancing, the characteristics of the application layer are also considered, that is, the meaningful application layer content in the control request is controlled, and the device shadow component selection mode set by the load balancing device is used to determine the final selected specified device shadow component.

[0048] Before the networking information of the specified Internet of Things device and the device real-time data of the specified Internet of Things device are sent to the specified device shadow component, the ID of the specified device shadow component can be subjected to hash calculation to obtain a first hash value; the first hash value is subjected to modulo operation on 2^32 of the hash ring to obtain a first modulo result, and the first modulo result is mapped to the hash ring; the ID of the specified Internet of Things device is subjected to hash calculation to obtain a second hash value; the second hash value is subjected to modulo operation on 2^32 of the hash ring to obtain a second modulo result; finally, the second modulo result is clockwise searched to obtain the adjacent first modulo result, and the specified Internet of Things device is associated with the specified device shadow component. The algorithm is a consistent hash algorithm, which organizes the entire hash value space into a hash ring in a clockwise direction, and the hash ring is composed of 2^32 points.

[0049] It should be noted that through the above process, only a small part of data in the ring space needs to be relocated when the device shadow component is added or deleted, and only part of the cache will be invalidated, so that all pressure is not concentrated on the backend server at the same time, and good fault tolerance and scalability are achieved.

[0050] In the embodiments of the present application, when it is determined that the arbitrary device shadow component is the specified device shadow component, the second modulo result can be clockwise searched to obtain a third modulo result of the adjacent arbitrary device shadow component; if it is determined that the arbitrary device shadow component stores the networking information of the specified Internet of Things device and the device real-time data of the specified Internet of Things device, it is determined that the arbitrary device shadow component is the specified device shadow component.

[0051] Further, in the embodiments of the present application, if it is determined that the arbitrary device shadow component is not the specified device shadow component, the remaining device shadow components can be determined whether there is the networking information of the specified Internet of Things device and the device real-time data of the specified Internet of Things device, so as to determine the specified device shadow component in the remaining device shadow components, and the control request is forwarded to the specified device shadow component.

[0052] In the embodiments of the present specification, the data continuously reported by the specified Internet of Things device often has a causal relationship. Once the data of the specified Internet of Things device is allocated to different instances, the device event cannot be closed. Therefore, after the networking information of the specified Internet of Things device and the device real-time data of the specified Internet of Things device are sent to the specified device shadow component, the specified device shadow component can be partitioned according to the networking information and the device real-time data to determine a first partition of the specified Internet of Things device in the specified device shadow component, and the networking information and the device real-time data are stored in the first partition. Finally, after generating other networking information and device data of the specified Internet of Things device, the other networking information and real-time data of the specified Internet of Things device are stored in the first partition.

[0053] In the embodiments of the present specification, if the specified device shadow component is disconnected, since the networking information of the specified Internet of Things device is processed by a consistent hashing algorithm, the platform has good fault tolerance and scalability. In the implementation process, other normally working device shadow components can be determined first, and then the networking information is sent to the other normally working device shadow components, and the other normally working device shadow components are partitioned according to the networking information to determine a second partition of the specified Internet of Things device in the other normally working device shadow components, and the networking information is stored in the second partition. After generating other networking information of the specified Internet of Things device, the other networking information of the specified Internet of Things device is stored in the second partition.

[0054] It should be noted that the connection between the Internet of Things device and the Internet of Things platform in the embodiments of the present specification is stateful, and cannot directly use simple load balancing to share server pressure. In the face of a large number of Internet of Things device connection scenarios, the distributed device registry center can arbitrarily scale the number of application instances. After a single node fails, it can automatically adjust and reallocate instance tasks, thereby avoiding the risk of the entire system being unavailable and reducing system failure time.

[0055] It should be noted that in combination with the above technical features, the embodiments of the present specification propose a distributed device registry center of an Internet of Things platform. When the number of device connections increases, the device registry center can be freely expanded and has no single point of failure risk.

[0056] The distributed device registry center is composed of four-layer load balancing software, network components, device shadow components, and seven-layer load balancing software.

[0057] The functions of each component are introduced as follows.

[0058] The four-layer load balancing software is used to forward network connection requests from the Internet of Things device.

[0059] The network component is the actual receiver of the service from the IoT device connection. The four-layer load balancing software uses a round-robin strategy for the request distribution of the network component, so all network components are equal, and the addition and deletion of nodes will not affect the entire service.

[0060] The device shadow component maintains the metadata and real-time data of the device. The "shadow" of the specified IoT device in the information system is constructed through the calculation of these data. The platform must ensure that the data reported by the same specified IoT device is always distributed to a certain device shadow component, because the data continuously reported by the specified IoT device often has a causal relationship, and once the specified IoT device data is allocated to different instances, it will cause the specified IoT device event to be unable to close. In addition, the metadata of the specified IoT device can be cached in the application according to the partition, to speed up the data access speed in the calculation process. In order to ensure that the data reported by the same specified IoT device is always distributed to the same device shadow component, the platform uses a consistent hashing algorithm to partition the device shadow instance managed by the device shadow component. When the device shadow component is added or deleted, the re-partitioning of the device shadow will be automatically triggered. Finally, the continuous availability of the device shadow component is ensured.

[0061] The seven-layer load balancing software is used to distribute the request data from the user.

[0062] The relationship between the components in the distributed device registration center can be seen in Figure 2 The distributed device registration center architecture diagram is shown.

[0063] The process of IoT device data uplink and downlink is introduced as follows:

[0064] The IoT device data uplink flowchart is shown in Figure 3 , and the details are as follows:

[0065] 1. The device is connected to the four-layer load balancing software;

[0066] 2. The four-layer load balancing software uses a round-robin strategy to forward the connection service to a network component;

[0067] 3. The network component records the association relationship between the IoT device and the current network component in the database;

[0068] 4. The network component processes the network connection from the IoT device, and uses a consistent hashing algorithm to send the device data to a device shadow node;

[0069] 5. The device shadow node processes and stores the IoT device data.

[0070] The IoT device data downlink flowchart is shown in Figure 4 , and the details are as follows:

[0071] 1. The user initiates a control device request to the platform;

[0072] 2. The seven-layer load balancing software uses a round-robin strategy to forward the request to a device shadow node;

[0073] 3. The device shadow node determines whether the device to be controlled is managed by the node, and if not, forwards to the actual management shadow node. The basis for the determination is a consistent hashing algorithm;

[0074] 4. The shadow node obtains the Internet of Things device information for verification, obtains the actual network components connected by the Internet of Things device, and notifies the request to the network component;

[0075] 5. The network component issues a device control instruction.

[0076] The following describes how each component solves the single point of failure to achieve automatic expansion:

[0077] 1. Network component: This component is used for the connection between the platform and the device, and the state information maintained is persisted to the database. The device disconnection or reconnection updates the information. Since the four-layer load balancing software uses a round-robin strategy to distribute requests, each network component is equally replaceable and there is no single point of risk.

[0078] 2. Device shadow component: Each device shadow component specifically manages the shadow of which device, depending on the unique ID of the device and the number of device shadow components in the cluster. As known from the consistent hashing algorithm, when the device is determined and the number of device shadow components in the cluster is determined, a unique device shadow component can be obtained. When the number of device shadow components in the cluster changes, the relationship can be recalculated and there is no single point of risk.

[0080] The request forwarding unit 502, upon receiving a network connection request for a specified Internet of Things device, randomly forwards the network connection request to any specified network component through the round-robin strategy of the four-layer load balancing software;

[0081] The networking information generation unit 504 processes the network connection request through the specified network component and establishes a connection between the specified Internet of Things device and the registration center to generate the networking information of the specified Internet of Things device;

[0082] The device deployment unit 506 sends the networking information of the specified Internet of Things device and the device real-time data of the specified Internet of Things device to the specified device shadow component, so that the networking information and the device real-time data are managed by the specified device shadow component, and when a user issues a control request for the specified Internet of Things device, the control request is randomly forwarded to any device shadow component through the polling strategy of the seven-layer load balancing software, if it is determined that the any device shadow component is the specified device shadow component, the control request is sent to the specified network component through the networking information and the device real-time data of the specified device shadow component, and the control request is sent to the specified Internet of Things device through the specified network component.

[0083] Further, before the device deployment unit 506 performs the sending of the networking information of the specified Internet of Things device and the device real-time data of the specified Internet of Things device to the specified device shadow component, the apparatus further comprises a device association unit.
