Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present application more clear, the embodiments of the present application will be further described in detail with reference to the accompanying drawings.
The following explains an application scenario of the present application.
The application is applied to an application scene of resource synchronization of the Internet of things equipment. The Internet of things comprises cloud equipment and Internet of things equipment, connection is established between the cloud equipment and the Internet of things equipment, connection is established between the Internet of things equipment and the Internet of things equipment, and the cloud equipment can provide resources for the Internet of things equipment. The resources referred to herein are data in nature.
Referring to fig. 1, a flowchart of a resource synchronization method provided in an embodiment of the present application is shown, where the resource synchronization method may be applied to a first internet of things device. The resource synchronization method may include:
After the first Internet of Things device is activated, the first Internet of Things device may access the Internet of Things (IoT).
After accessing the internet of things, the first internet of things device may determine a resource that the first internet of things device needs to acquire, where the resource is a resource to be synchronized. The determination method of the resource to be synchronized by the first internet of things device is various, and will be described below with reference to a specific application scenario, which is not described herein again.
In this embodiment, the first equipment of the internet of things may further detect whether a second equipment of the internet of things capable of providing the resource to be synchronized exists, and if the second equipment of the internet of things capable of providing the resource exists, the resource is acquired from the second equipment of the internet of things; and if the second connected device capable of providing the resource does not exist, acquiring the resource from the cloud device.
It should be noted that, in this embodiment, the internet of things device that needs to acquire the resource is referred to as a first internet of things device, and the internet of things device that provides the resource is referred to as a second internet of things device.
In summary, according to the resource synchronization method provided in the embodiment of the present application, after the first internet of things device is started, if the first internet of things device needs to perform resource synchronization, the resource to be synchronized may be determined first, and then the resource may be acquired from the second internet of things device in which the resource is stored, so that the first internet of things device may acquire the resource only from the second internet of things device that has already acquired the resource provided by the cloud device in the internet of things, and does not need to acquire the resource from the cloud device, and the dependency on the cloud device may be reduced, thereby reducing the load of the cloud device, avoiding the problem of cloud device breakdown due to the memory leakage of the cloud device because the load of the cloud device is large, and also avoiding the problem of large time delay or resource failure due to the failure of resource synchronization because the resource cannot be fed back in time because the load of the cloud device is large, therefore, the effects of avoiding the collapse of cloud equipment, reducing the time delay of resource synchronization and improving the accessibility of resources are achieved. In addition, because the first internet of things device can acquire resources from the second internet of things device, the cooperation between nodes in the internet of things can be enhanced, and the purpose of high cohesion of the internet of things is achieved.
In this embodiment, the first internet of things device may actively acquire resources after being started, or the cloud device may actively issue resources to the first internet of things device after acquiring the resources, and the two application scenarios are described below.
Please refer to fig. 2, which shows a flowchart of a resource synchronization method according to another embodiment of the present application, where the resource synchronization method can be applied to a first internet of things device. The resource synchronization method may include:
After the first internet of things device is started, the first internet of things device can read the resource list stored on the disk. The Resource list may at least include a Resource identifier (Resource ID), a Resource Status (Status), and Data (Data), and may also include other information, which is not limited in this embodiment.
The resource identifier is MD5 (Message-Digest Algorithm) value of data, for example, the resource identifier of a resource is 2C7470FBE938689B with a length of 16 bits.
The resource state values are two, wherein one of the resource states is defined as a first resource state, the other one of the resource states is defined as a second resource state, the first resource state is used for indicating the synchronized resource of the first equipment in the internet of things, and the second resource state is used for indicating the unsynchronized resource of the first equipment in the internet of things. For example, if the two values are 0 and 1, respectively, then 0 may be set to correspond to the first resource state, and 1 may be set to correspond to the second resource state, so that when the value of the resource state in the resource list is 1, it indicates that the first internet of things device has synchronized the resource; when the value of the resource state in the resource list is 0, it indicates that the first internet of things device does not synchronize the resource.
Data may be represented in formats such as { "faceSetToken": "asdsasd" }.
After the first internet of things device obtains the resource list, the resource list can be loaded into the cache of the first internet of things device.
Still taking the example in step 202 as an example, the first internet of things device may select a resource list with a resource status value of 1.
And step 204, determining the resource indicated by each selected resource list as the resource to be synchronized.
After the first internet of things device is started, the first internet of things device may read the node list stored on the disk, and the reading sequence of the node list and the resource list is not limited in this embodiment. The Node list may at least include a Node ID (Node ID) and an IP (Internet Protocol) address.
The node identifier is a node code value used for indicating a node (namely, an internet of things device) which has uniqueness in the internet of things. For example, one node is identified as PAD-SCC 2.
The IP address is the IP address of the node in the Internet of things. For example, one IP address is 192.168.1.10.
After the first internet of things device obtains the node list, the node list may be loaded into a cache of the first internet of things device.
And step 206, establishing connection with the second connected device indicated by each node list.
The first internet-of-things device may establish a long connection with each second internet-of-things device, which may pass the heartbeat, so establishing a long connection with the second internet-of-things device may also be referred to as initiating a node heartbeat task.
Besides establishing connection with the second internet-of-things device, the first internet-of-things device also needs to establish connection with the cloud device, and then the first internet-of-things device can be considered to be connected to the internet of things. After the first internet of things device accesses the internet of things, the first internet of things device can also obtain a resource list and a node list from the cloud device so as to update the resource list and the node list stored in the first internet of things device.
After determining the resource to be synchronized, the first internet-of-things device may poll each connected second internet-of-things device for the resource. For example, the first internet-of-things device may send a polling request carrying the resource identifier of the resource to be synchronized to each second internet-of-things device.
Since the number of second internet-of-things devices connected to the first internet-of-things device is large, the polling order of the second internet-of-things devices can be set. For example, the polled second associated device may be randomly determined, or the second associated device may be sorted, and the polled second associated device may be determined according to the sorting order.
In one implementation, before polling each second connected device for resources in a predetermined order, the method further comprises: acquiring a feedback score of each connected second equipment, wherein the feedback score and the times of the second equipment providing resources to the first equipment are in positive correlation; and sequencing the corresponding second-link equipment according to the sequence of the feedback scores from large to small, wherein the sequencing sequence of the second-link equipment is the polling sequence of the second-link equipment.
A connection pool is maintained in the memory of the first internet of things device, and a long connection node which survives, namely, a second internet of things device which is in long connection with the first internet of things device, is maintained in the connection pool. The connection pool scores the condition that each second networking device returns the resource to the first networking device. For example, each time a second networking device successfully returns resources to a first networking device, the score of the second networking device is increased by 1 point, and the connection pool is sorted in a reverse order according to the score of each second networking device, that is, the higher the score is, the position in the connection pool is closer to the front.
And step 208, stopping polling after a second associated device storing the resource is determined, and acquiring the resource from the determined second associated device.
The second internet-of-things device may return a determination message to the first internet-of-things device when determining that the resource exists according to the polling request, the first internet-of-things device may determine the second internet-of-things device as the second internet-of-things device in which the resource is stored, and then send a resource acquisition request to the second internet-of-things device, and the second internet-of-things device may send the resource to the first internet-of-things device according to the resource acquisition request.
If the first equipment of the Internet of things does not receive the confirmation message sent by any second equipment of the Internet of things, it is determined that the second equipment of the Internet of things capable of providing the resource does not exist, and the resource is obtained from the cloud equipment.
After the first internet of things device successfully acquires the resources, the resource list stored in the disk and the cache can be updated, that is, the resource state in the resource list is modified from the second resource state to the first resource state.
In summary, according to the resource synchronization method provided in the embodiment of the present application, after the first internet of things device is started, if the first internet of things device needs to perform resource synchronization, the resource to be synchronized may be determined first, and then the resource may be acquired from the second internet of things device in which the resource is stored, so that the first internet of things device may acquire the resource only from the second internet of things device that has already acquired the resource provided by the cloud device in the internet of things, and does not need to acquire the resource from the cloud device, and the dependency on the cloud device may be reduced, thereby reducing the load of the cloud device, avoiding the problem of cloud device breakdown due to the memory leakage of the cloud device because the load of the cloud device is large, and also avoiding the problem of large time delay or resource failure due to the failure of resource synchronization because the resource cannot be fed back in time because the load of the cloud device is large, therefore, the effects of avoiding the collapse of cloud equipment, reducing the time delay of resource synchronization and improving the accessibility of resources are achieved. In addition, because the first internet of things device can acquire resources from the second internet of things device, the cooperation between nodes in the internet of things can be enhanced, and the purpose of high cohesion of the internet of things is achieved.
Please refer to fig. 3, which shows a flowchart of a resource synchronization method according to another embodiment of the present application, where the resource synchronization method can be applied to a first internet of things device. The resource synchronization method may include:
After the first internet of things device is started, the first internet of things device can access the internet of things.
The leader node is a node selected from nodes belonging to the same group, and there are many grouping rules, for example, nodes in the same network segment are grouped into one group, and the grouping rule is not limited in this embodiment.
In this embodiment, after a new node is accessed, the cloud device may divide nodes in the same network segment into a group, and each group will elect a leader node, and the cloud device may elect a leader node when a predetermined condition is satisfied, where the predetermined condition may be at least one of ① that the number of nodes in a group within a certain time period interrupt the connection reaches a set number, ② that the leader node is disconnected, ③ that the leader election in a group is performed at regular time, ④ that the response time of the leader within a certain time period is too long, and the following describes a flow of electing the leader node.
Before receiving the resource identifier sent by the leader node of the first internet of things device, the method further includes: receiving an election notification sent by cloud equipment, wherein the election notification is used for electing a leader node; and sending the equipment information of the first internet of things equipment to the cloud equipment, wherein the equipment information is used for the cloud equipment to elect the leader node.
The cloud equipment sends election notification to nodes in the same network segment, then collects node responses, calculates by using a Raft algorithm to obtain a leader node, and records the corresponding relation between the network segment and the leader node. Then, the cloud device can detect the connection state of each leader through heartbeat, and reselect the leader node if an offline leader node exists; and if the offline nodes do not exist, continuously detecting the connection state of each leader through heartbeat.
After the leader node information is stored in the cloud device, the cloud device can actively issue the resource after acquiring the resource. At this time, the cloud device may newly create a task to be issued, set the task state to be issued, and then determine whether each first internet of things device that needs to synchronize resources corresponds to the same leader node (i.e., belongs to the same network segment); if each first internet of things device needing resource synchronization corresponds to the same leader node, the resource is issued to the leader node, the task state is set to be issued, and after a receiving confirmation message sent by the leader node is received, the task state is set to be received; and if each first internet of things device needing resource synchronization corresponds to different leader nodes, the resource is issued to each corresponding leader node, the task state is set to be issued, and after receiving the receiving confirmation message sent by each leader node, the task state is set to be received. When the cloud device issues the resource, the cloud device may send a resource identifier, data, and a node identifier set to the leader node, where the node identifier set includes identifiers of nodes that need to synchronize the resource.
It should be noted that, if the leader node fails to receive the resource, the cloud device may reselect the leader node, and the election process is described in detail in the foregoing description, which is not described herein again.
After obtaining the resource issued by the cloud device, the leader node can obtain each node (including the first internet of things device) needing the resource synchronization in the network segment from the node identifier set, and then send the resource identifier to the nodes in parallel through long connection between the leader node and each node to inform the nodes of synchronizing the resource.
And step 306, receiving the resource sent by the leader node to the first internet of things device according to the resource obtaining request.
After the first internet of things device successfully acquires the resources, a receiving confirmation message can be sent to the leader node through the long connection, and the leader node can delete the node identifier from the acquired node identifier. In addition, the first internet of things device can also update the resource list in the disk and the cache, that is, the resource state in the resource list is modified from the second resource state to the first resource state.
In summary, according to the resource synchronization method provided in the embodiment of the present application, after the first internet of things device is started, if the first internet of things device needs to perform resource synchronization, the resource to be synchronized may be determined first, and then the resource may be acquired from the second internet of things device in which the resource is stored, so that the first internet of things device may acquire the resource only from the second internet of things device that has already acquired the resource provided by the cloud device in the internet of things, and does not need to acquire the resource from the cloud device, and the dependency on the cloud device may be reduced, thereby reducing the load of the cloud device, avoiding the problem of cloud device breakdown due to the memory leakage of the cloud device because the load of the cloud device is large, and also avoiding the problem of large time delay or resource failure due to the failure of resource synchronization because the resource cannot be fed back in time because the load of the cloud device is large, therefore, the effects of avoiding the collapse of cloud equipment, reducing the time delay of resource synchronization and improving the accessibility of resources are achieved. In addition, because the first internet of things device can acquire resources from the second internet of things device, the cooperation between nodes in the internet of things can be enhanced, and the purpose of high cohesion of the internet of things is achieved.
