Accordingly, the regions illustrated in the figures are of a schematic nature and the shapes of the regions shown in the figures are illustrative of the specific shapes of regions of the element and are not intended to be limiting.

In a first aspect, the present disclosure provides a network service method for a master node of a mesh network.

Mesh network is also called a fully meshed network and a fully interconnected network, which is composed of multiple nodes. And all nodes are connected to each other, so all connections form a "mesh". Among the nodes of the Mesh network, there is a master node, which is a node that functions like a server and is connected to the external client (Web). The other nodes in the Mesh network are called child nodes.

The disclosed method is executed by the master node in the mesh network to provide network services (Web Server) to the client, such as providing network resources required by the client.

Referring to FIG. 1 , the method of the embodiment of the present disclosure may include S101 to S104.

In S101, obtain performance information of each sub-node in the mesh network.

The master node obtains performance-related information (or its own available resource information) of each sub-node in the mesh network through some methods, such as the CPU computing power, memory amount, hard disk amount, load, etc. of each sub-node.

It should be understood that the master node must of course "record" performance information. For example, a performance table (or child node performance table) can be set up and the performance information of each child node is stored in the performance table.

Among them, since the situation of sub-nodes in the mesh network is constantly changing (such as new sub-nodes, sub-nodes going offline, sub-node performance changes, etc.), the performance information here can be obtained multiple times, such as every Performance information is updated after a period of time.

In S102, allocate network resources to at least one child node based on at least the performance information.

After obtaining the performance information of each sub-node, the network resources that each sub-node can process can be determined based on the performance information, and the network resources originally stored in the main node are allocated to the corresponding sub-nodes for storage and processing by the sub-nodes.

There are various specific ways to determine how to allocate network resources to child nodes. For example, a self-learning model can be set up, performance information can be input into the self-learning model, and the self-learning model calculates the network resources that should be allocated to each child node.

It should be understood that the master node must of course "record" the allocation of network resources. For example, an allocation table (or resource allocation table) can be set up, and which network resources each child node is allocated are stored in the allocation table.

Among them, since the conditions of network resources and sub-nodes are constantly changing, the allocation of network resources can also be constantly changing; accordingly, the contents in the above allocation table must also be constantly updated.

Among them, in addition to being allocated to a child node, the same network resource can also be allocated to Another backup child node, so the allocation table can also be sent to the child node, so that the child node can obtain network resources from the corresponding backup child node when the network resources cannot be provided in time.

In S103, obtain the client's resource request and determine the target sub-node where the target network resource is located.

Among them, resource request is used to request target network resources.

When the client (Web) needs to use network resources, it will send a resource request to the master node. The resource request includes the network resources that the client needs to use, that is, the target network resources. After the master node receives the resource request, it can determine the target network resource required by the client based on the resource request, and query in the allocation table which sub-node (or sub-nodes) the target network resource is located, that is, the target sub-node.

In S104, obtain the target network resource from the target sub-node and send the target network resource to the client.

After the master node determines the target sub-node where the target network resource is located, it can send a request to the target sub-node, and the target sub-node will provide the target network resource (the target sub-node can also process the provided target network resource accordingly), that is, The target sub-node actually implements the network service (Web Server) function; then, the master node can send the obtained target network resources to the client, so that the client can obtain the required target network resources.

In the disclosed embodiment, the main node of the mesh network allocates network resources to each sub-node at least based on the performance of each sub-node. Therefore, when the client (Web) requires network resources, the actual network resources are processed and processed by each sub-node. Provided, that is, each sub-node can share part of the network service (Web Server) function, thereby making full use of the capabilities of all cluster devices in the mesh network, avoiding long-term idleness of sub-nodes, achieving load balancing, and enabling multiple sub-nodes to be concurrent ( concurrent) work to speed up the response speed of the mesh network and improve the performance of the mesh network.

In some embodiments, referring to Figure 2, allocating network resources to at least one child node (S102) based at least on performance information may include: S1021, allocating network resources to at least one child node based on network resource usage and performance information.

As a way to implement the present disclosure, when allocating resources, in addition to considering the performance information of sub-nodes, the actual usage of different network resources (such as the frequency of use within a period of time) can also be considered to achieve more accurate and effective allocation. .

It should be understood that the master node must of course "record" the usage of network resources. For example, a resource table (or resource usage frequency table) can be set up to record the number (frequency) of network resources being used (such as requested by a client) within a certain period of time. .

Among them, as network resources are continuously used, the resource table should also be continuously updated.

In some embodiments, referring to Figure 2, before obtaining the performance information of each sub-node in the mesh network (S101), it also includes: S1001, performing a first authentication on each connected sub-node, and determining the sub-node that passes the first authentication. Nodes are child nodes in the mesh network.

As a way to implement the present disclosure, after the mesh network is physically networked, the master node can also first authenticate (verify) each connected sub-node to determine whether it is indeed added to the mesh network for subsequent work. Ensure that all child nodes actually joining the mesh network are safe and legal.

In some implementations, the first authentication is based on a preset public key and a private key; the private key is prestored in the master node, and the public key is disclosed to each child node.

For example, public keys and private keys can be used for authentication between the master node and the child nodes.

For example, the public key and private key can be preset, and the master node broadcasts the first authentication message to each child node. After receiving it, the child node encrypts a random number with the public key and returns it to the master node together with its own address and other information. The node tries to decrypt with the private key. If it can be decrypted successfully, the topology relationship will be determined based on the address of the child node and stored in the topology table. If it cannot be decrypted, it will end. The corresponding child node will not be actually added to the mesh network (it will not be added to the topology table). ).

At the same time, the master node can also store random numbers as tokens in the authentication table for subsequent authentication of child nodes.

It should be understood that the specific authentication methods based on public keys and private keys are not limited to the above examples and will not be described in detail here.

In some embodiments, referring to Figure 2, obtaining the target network resource from the target sub-node, and sending the target network resource to the client (S104) includes: S1041, performing a second authentication on the target sub-node. If the second authentication is passed, Next, obtain the target network resource from the target child node and send the target network resource to the client.

As a way to implement the present disclosure, when the target network resources are to be obtained from the target sub-node, authentication can also be performed first, and only after the authentication is passed, the target network resources are actually obtained. source and sent to ensure the correctness of the obtained target network resources.

Among them, the specific methods of second certification are diverse.

For example, the above random number obtained from the child node can be sent to the target child node as a token; the target child node authenticates the random number (token), and if correct, provides the target network resources and sends a new random number at the same time. to the master node, if it fails, it ends; the master node authenticates the new random number received. If it succeeds, the second authentication succeeds, obtains the target network resource and sends it to the client, and stores the new random number (equivalent to the update token). If Failure ends.

In some embodiments, referring to Figure 2, obtaining the client's resource request and determining the target sub-node where the target network resource is located (S103) includes: S1031. Perform a third authentication on the client that issued the resource request. After the third authentication is passed, In this case, determine the target sub-node where the target network resource is located.

As a way to implement the present disclosure, when receiving a resource request from a client, the client can also be authenticated first, and only the target network resource is provided to the client after passing the authentication, so as to ensure that the target network resource is provided to the security of the client.

In some implementations, the third authentication is token authentication.

For example, the authentication between the client and the master node may use token authentication.

For example, the client may first send a third authentication request to the master node to obtain the random value provided by the master node, encrypt it using a predetermined encryption algorithm (such as the encryption algorithm of the network service), and use the encrypted random value as The token is carried in the resource request and sent to the master node. The master node decrypts it using the same algorithm. If the correct random value can be obtained, the third authentication is passed and the authentication request continues to be processed. If it fails, it ends.

It should be understood that the specific method of token authentication is not limited to the above examples and will not be described in detail here.

In a second aspect, the present disclosure provides a network service method for sub-nodes of a mesh network.

The disclosed method is executed by the sub-nodes in the mesh network (the mesh network with the above master node) to provide network services (Web Server) to the client, for example, to provide network resources required by the client.

Referring to Figure 3, the method of the embodiment of the present disclosure includes S201 to S203.

In S201, send its own performance information to the master node of the mesh network.

In S202, network resources allocated by the master node are received and stored locally.

In S203, the target network resource is sent to the master node according to the master node's request for the target network resource.

Among them, the target network resource is the network resource stored locally on the child node.

As before, the sub-nodes in the mesh network need to send their own performance information to the master node, so that the master node can determine the network resources that should be allocated based on the performance information of each sub-node (and of course the usage of network resources); After that, each sub-node receives the corresponding network resources and stores them locally respectively; thus, when the client requests the target network resource from the main node, the sub-node (target sub-node) where the target network resource is located will receive the request from the main node. And process the target network resources stored by itself and provide them to the master node.

In some embodiments, referring to Figure 4, sending one's own performance information to the master node of the mesh network (S201) includes: S2011, periodically actively sending one's own performance information to the master node of the mesh network.

As an implementation method of the present disclosure, each child node can actively send performance information to the master node periodically, thereby reducing the load of the master node.

It should be understood that it is also feasible if the child node sends performance information according to the request of the master node or other methods.

In some embodiments, referring to Figure 4, before sending its own performance information to the master node of the mesh network (S201), the method further includes: S2001, performing a first authentication with the master node.

As an implementation method of the present disclosure, before completing the actual networking, the sub-node may also perform authentication with the master node.

The specific authentication method may correspond to the first authentication of the master node, and will not be described in detail here.

In some embodiments, referring to Figure 4, according to the master node's request for the target network resource, sending the target network resource to the master node (S203) includes: S2031, performing a second authentication with the master node. When the second authentication is passed, Next, send the target network resources to the master node.

As an implementation method of the present disclosure, when providing target network resources to the master node, the sub-node may also perform authentication with the master node.

The specific authentication method may correspond to the second authentication of the master node, and will not be described in detail here.

In the third aspect, referring to FIG. 5 , the present disclosure provides a master node for use in a mesh network, wherein the master node is configured to execute any network service method according to the embodiment of the present disclosure.

In some embodiments, the master node includes a processor and a memory, and a computer program is stored on the memory. When the computer program is executed by the processor, it can implement any network service method in the embodiments of the present disclosure.

In the fourth aspect, referring to FIG. 6 , the present disclosure provides a sub-node for use in a mesh network, wherein the sub-node is configured to execute any network service method according to the embodiment of the present disclosure.

In some embodiments, the child node includes a processor and a memory, and a computer program is stored on the memory. When the computer program is executed by the processor, it can implement any network service method in the embodiments of the present disclosure.

In the fifth aspect, referring to FIG. 7 , the present disclosure provides a computer-readable medium on which a computer program is stored. When the computer program is executed by a processor, it can implement any network service method according to the embodiment of the present disclosure.

Among them, the processor is a device with data processing capabilities, including but not limited to a central processing unit (CPU), etc.; the memory is a device with data storage capabilities, including but not limited to random access memory (RAM, more specifically such as SDRAM). , DDR, etc.), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), flash memory (FLASH); the I/O interface (read-write interface) is connected between the processor and the memory, enabling memory and Information exchange of processors, including but not limited to data bus (Bus), etc.

By way of example, the implementation architecture and specific processes of the embodiments of the present disclosure are introduced.

For example, referring to Figure 8, the embodiment of the present disclosure can be implemented by four modules, namely, authentication module, collection module, distribution module, and implementation module.

Among them, the authentication module consists of two parts. The first part is used for security authentication (first authentication and second authentication) between the main node and the sub-node to establish a secure link mechanism between the two to ensure the security between the two. communication to prevent malicious attacks; the second part is used for security authentication (third authentication) between the master node and the client (web) to ensure data security sex.

The collection module is used to enable the sub-nodes to regularly and proactively report their own performance information (available resource information) to the master node, and the master node can evaluate the equipment capability value of each sub-node based on a predetermined algorithm.

The allocation module is used to count the usage frequency of network resources, and allocate network resources to each child node according to the frequency and the equipment capability value of the child node through a learning algorithm (self-learning model), and the child node will allocate the network resources Stored locally, when the client requests the corresponding network resource (target network resource), the master node queries the target sub-node where the target network resource is located, obtains the target network resource from it, and provides it to the client.

The implementation module is used to free the master node from resource scheduling after passing through the above modules. It is mainly responsible for security authentication, resource allocation, data update, forwarding requests, etc.

For example, referring to Figures 9 to 11, the exemplary process of the embodiment of the present disclosure may include three stages: mesh network initialization, mesh network update, and client requesting network resources.

Among them, referring to Figure 9 and Figure 10, the mesh network equipment has a pre-prepared public key and private key when it leaves the factory (of course, the public key and private key of the master node are used), and the mesh network initialization phase may include A101 to A109.

On A101, after the physical mesh network is successfully established, the master node broadcasts a message to each child node.

At A102, the online child node responds, encrypts topology information such as random numbers and address information with the public key, and sends it to the master node.

At A103, the master node attempts to decrypt the received information with the private key and continues if successful, otherwise the authentication fails.

At A104, the master node updates the decrypted address information to the topology table (recording the topology information of the mesh network); and stores the decrypted random number into the authentication table (records the corresponding authentication information of each sub-node, such as tokens) , used as a token to authenticate the corresponding child node in the subsequent process.

At the same time, when the child node can also update the token regularly, the master node should also update the authentication table accordingly.

For example, the header format of the topology table can be as follows:

For example, the header format of the certification table can be as follows:

At A105, the child node actively sends its own performance information to the master node regularly and carries the token.

At A106, the master node verifies the validity of the token. If it is valid, continue. If it is not valid, the authentication fails.

At A107, the master node calculates the capability value of each child node and updates the performance table (recording the performance information of each child node, such as the capability value), and then based on the network resources in the resource table (recording the usage of network resources, such as frequency of use) Using frequency and capability values, generate an allocation table (recording the allocation of network resources to child nodes) according to the resource allocation algorithm.

At the same time, the master node can also determine whether the token has been updated based on the authentication table, and if so, update the authentication table.

For example, the header format of the performance table can be as follows:

For example, the initial resource table can be set based on experience, and the header format of the resource table can be as follows:

For example, the header format of the allocation table can be as follows:

At A108, if the system version number of the child node is the same as that of the master node, it means that the network resources have been allocated to the child node. If they are different, the master node stores the corresponding network resources in the child node according to the allocation table.

At A109, mesh network initialization is completed.

The mesh network update stage can include A201 and A202.

In A201, if the master node does not receive the performance information sent regularly by the child node within the specified time, it will send a confirmation message to the child node. If it still does not receive a reply from the child node, it is considered that the child node has been offline. Update Topology table (delete the information of the corresponding sub-node), performance table (delete the information of the corresponding sub-node), allocation table, and reallocate network resources.

Among them, the redistribution can be to use the backup sub-node as the main sub-node, or (for example, the backup sub-node is also offline) to calculate the corresponding network according to the reuse resource allocation algorithm. Which child node the resource is allocated to.

At A202, the master node broadcasts regularly to allow newly added child nodes to join the mesh network in the above manner.

Referring to Figures 9 and 11, the phase of the client requesting network resources may include A301 to A306.

In A301, the client obtains the random value x through HTTP negotiation request, encrypts x according to the predetermined encryption algorithm, and obtains x_encode.

In A302, the client sends a resource request carrying x_encode as a token to the master node, requesting network resource y (target network resource).

In A303, the master node decrypts according to the corresponding algorithm. If it can obtain x, it will continue. If it cannot, the authentication will fail.

In A304, the master node finds the child node where the network resource y is located according to the allocation table, and sends a request carrying the token t (the most recently updated random number) to the child node.

At A305, the child node authenticates based on the token t. If it passes, the network resource y is processed, and the network resource y is sent to the master node, while carrying the newly generated token s (random number updated again).

In A306, the master node decrypts the token s for authentication. If it passes, the network resource y is sent to the client, and the token and network resource usage frequency are updated (because the network resource y is used).
