Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without inventive step, are intended to be within the scope of the present invention.
It should be noted that descriptions in this disclosure as to "first", "second", etc. are for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present disclosure, "a plurality" means at least two, e.g., two, three, etc., unless explicitly specifically limited otherwise.
In addition, technical solutions between the various embodiments of the present disclosure may be combined with each other, but must be based on the realization of the capability of a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should be considered to be absent, and is not within the protection scope of the present invention.
Wireless Mesh (Mesh) networks have evolved into effective solutions for a variety of wireless access networks, such as broadband home networks, community networks, enterprise networks, and metropolitan area networks, by virtue of multi-hop interconnection and Mesh topology characteristics. Taking bluetooth low energy Ble-Mesh network as an example, many-to-many communication is realized based on bluetooth low energy technology, and all devices added in Mesh network can communicate with each other. The device which does not join the Mesh network is called an undistributed device (unprotected device) or a node to be provisioned, and the device which has joined the Mesh network is called a node (node), also called a provisioned device (provisioned device) or a provisioned node. In the embodiment of the disclosure, whether the distribution network is finished is determined according to the execution result of the operation of the related distribution network, and is not simply determined according to the name of the node. In the networking/distribution process of the Ble Mesh network and when a new node is added, a network distribution device (provisioner) and a newly added node (provisionee) are required to be within the radio frequency coverage of the two, as shown in fig. 1. Therefore, for the scale Ble Mesh network, a user needs to carry distribution network equipment to be near a new node for distribution; for a newly-built Mesh network, it takes a long time to complete the distribution of the network of all the nodes according to the existing standard flow. For example, the preliminary estimation requires about 4s to complete the distribution network of one node, and for a Mesh network including 500 nodes, the total time length requires about 33 minutes. It can be seen that this process is not only time consuming, but also requires personnel to move the distribution network equipment to reach within the radio frequency coverage of each node. The whole distribution network process has poor convenience, long time consumption and poor user experience, and is not beneficial to the application and popularization of the Mesh network technical scheme.
The disclosed embodiment provides a distribution network scheme applied to a Mesh network, wherein a multi-stage diffusion type distribution network scheme with distribution network nodes serving as distribution network equipment is adopted, and each stage of distribution network equipment distributes a network to nodes to be distributed in a self coverage range according to registration verification information of the configured distribution network nodes, so that the distribution network speed of the nodes in the whole Mesh network can be obviously improved, the distribution network coverage range of the Mesh network is greatly expanded, and the convenience of Mesh network distribution is obviously improved.
It can be known that a process of adding a device into the Mesh network is called a distribution network (provisioning), a device for driving the provisioning process is called a distribution network device (provisioning), the device after the successful provisioning becomes a Mesh node (node), and a series of configurations are performed to execute a normal application/service function.
Taking the Ble Mesh network as an example, the network distribution process includes 5 stages, as shown in fig. 2:
beacon: the device/node (to-be-configured network) initiates a broadcast to inform the distribution network;
invitation: a distribution network device (provider) sends a distribution network invitation PDU, and a device/node (to be distributed) responds and replies information about the device/node in a Provisioning Capabilities PDU;
exchange public keys: public keys are exchanged between distribution network equipment (provider) and equipment/nodes (to-be-distributed network), and the public keys are used for generating Session keys when distribution network data are distributed;
authentication: identity authentication is carried out between the distribution network equipment (provider) and the equipment/node (to be distributed) through a specific action;
the Distribution of Distribution network data is distributed by the Distribution of provisioning data: a Session Key is derived from a public Key and private keys of two devices, the process of information interaction of a distribution network is encrypted by the Session Key, and distribution network data PDU containing' NetKey, deviceKey and AppKey.
It can be seen that the distribution network process defined by the Ble Mesh specification includes multiple steps of scanning, connection, key exchange, identity authentication, and the like, and the overall process time is long. The whole network depends on a core distribution network device/distribution network device to complete distribution of all nodes, longer time is needed, and the overall distribution network efficiency is low.
The embodiment of the present disclosure provides a method for distributing a network in a Mesh network of a wireless Mesh, as shown in fig. 3, including:

Namely, the node to be distributed is in the range of the distribution network device capable of distributing the network.
In some exemplary embodiments, the MAC address validation rule defines a condition that a MAC address of a node of a distributable network satisfies, which may be a MAC address range, a matching condition with a wildcard, or other forms of matching conditions, and is not limited to a specific form. And under the condition that the MAC address in the registration information of the node to be distributed accords with the MAC address verification rule, the registration information of the node to be distributed is verified to be legal, and the node to be distributed is determined to be a first distribution network node.

Namely, the node to be distributed is in the range of the distribution network device capable of distributing the network.

And under the condition that the unicast address in the registration information of the node to be distributed accords with the unicast address verification rule, the verification that the registration information of the node to be distributed is legal is indicated, and the node to be distributed is determined to be the first distribution network node. Namely, the node to be distributed is in the range of the distribution network device capable of distributing the network.
In some example embodiments, the unicast address validation rule comprises one or more sub-rules. Without conflict, a relationship that is "and" or "between multiple sub-rules.
In some exemplary embodiments, the UUID address list includes UUIDs of networks that can be currently distributed by the distribution network device, and in a case that the UUID in the registration information of the node to be distributed is included in the UUID address list, it indicates that the registration information of the node to be distributed is verified to be legitimate, and the node to be distributed is determined to be the first distribution network node. Namely, the node to be distributed is in the range of the distribution network which can be performed by the distribution network equipment.
In some exemplary embodiments, the UUID verification rule defines a condition that the UUID of a node of a distributable network satisfies, and the condition may be a UUID range, a matching condition with a wildcard, or other forms of matching conditions, and is not limited to a specific form. And under the condition that the UUID in the registration information of the node to be distributed conforms to the UUID verification rule, the registration information of the node to be distributed is verified to be legal, and the node to be distributed is determined to be the first distribution network node. Namely, the node to be distributed is in the range of the distribution network device capable of distributing the network.
In some exemplary embodiments, the UUID validation rule includes one or more sub-rules. Without conflict, a relationship that is "and" or "between multiple sub-rules.
It should be noted that, under the condition of no conflict, the registration verification information may include multiple items, and accordingly, when the registration information of the network node to be configured satisfies each item, it indicates that the registration information of the network node to be configured is verified to be legal, and it is determined that the network node is the first network node.
For example, the UUID in the registration information is 16 bits, wherein the first 8 bits are set before the device is produced, the last 8 bits are produced according to a certain encryption algorithm in the production process, and the overall 16-bit UUID has a certain rule.
Accordingly, the registration verification information includes: a UUID validation rule comprising:

As can be seen, compared with the distribution network flow shown in fig. 1, the distribution network flow between the distribution network device and the first distribution network node shown in fig. 4 omits a link of public key exchange and authentication, and can significantly improve the distribution network speed between a pair of nodes. Research shows that in some Mesh network applications, related nodes are all known controllable devices, and are not random devices in a general internet application environment, and based on the verification of the distribution network node to be configured by the distribution network device according to the registration verification information of the distribution network node configured by the distribution network device in step 310, it can be ensured that only the distribution network node to be configured within an allowable range can enter the distribution network link in step 320, and therefore, the security can be effectively ensured.

When the distribution network equipment scans the nodes to be distributed, a plurality of distribution network equipment can scan the same node to be distributed and determine the node to be the first distribution network node of the distribution network, and then send a distribution network invitation. At the moment, the same first distribution network node receives the distribution network invitations from the plurality of distribution network devices, at the moment, one of the first distribution network nodes is selected according to the distribution network device priority selection strategy to process, a distribution network inviting response is returned, the subsequent distribution network is carried out, and other distribution network invitations are discarded.
