The networking method of the Mesh network in the embodiment of the application is suitable for the closed Mesh network, such as a family WiFi Mesh network, and is characterized in that a user has uniqueness.
The embodiment of the application provides a networking method of a Mesh network, and only node equipment which is successfully authenticated is accessed into the Mesh network by authenticating the node equipment which is desired to be accessed into the Mesh network, so that equipment which does not belong to a Mesh network user is prevented from being accessed into the Mesh network, and the safety of the Mesh network is further ensured.

The following describes in detail each step of gradually implementing Mesh network networking in the embodiment of the present application:
step S101, when a network access request of a node device to be accessed to the network is received, the node device to be accessed to the network is authenticated according to message information carried by the network access request, and an authentication result is obtained.
When networking equipment of the Mesh network receives a network access request of node equipment to be accessed, the node equipment to be accessed is authenticated according to message information carried by the network access request, and an authentication result is obtained.
Illustratively, the authenticating the node device to be networked according to the message information carried by the network access request to obtain an authentication result specifically includes:
a1, decoding the message information carried by the network access request to extract Mesh network identification information and the identification information of the node equipment to be accessed from the message information;
a2, matching the extracted Mesh network identification information and the identification information of the node equipment to be networked with a prestored routing information table to determine whether the node equipment to be networked is effective node equipment;
a3, if the node device to be accessed to the network is determined to be a valid node device, obtaining an authentication result of successful authentication.
That is, the node device to be networked sends a networking request to the networking device of the Mesh network, where the networking request carries message information, where the message information includes Mesh network identification information and identification information of the node device to be networked. It should be noted that, in order to prevent the message information from being maliciously tampered, the message information is pre-encapsulated into a frame structure agreed with the networking device of the Mesh network, for example, the message information may be encapsulated in an internet protocol security IPSec manner, and the frame structure may be a self-defined frame structure, for example:
| *** | MAC header | Addr information | Device information | payload | Frame check | *** |
Therefore, after receiving a network access request sent by a node device to be accessed, a networking device of the Mesh network firstly decodes message information carried in the network access request according to a preset decoding mode corresponding to the encapsulation mode so as to extract Mesh network identification information and identification information of the node device to be accessed from the message information. And then, matching the extracted Mesh network identification information and the identification information of the node equipment to be networked with a prestored route information table to determine whether the node equipment to be networked is effective node equipment or not (defining the node equipment belonging to a Mesh network user as the effective node equipment), and if the extracted Mesh network identification information and the identification information of the node equipment to be networked are matched with the prestored route information table, determining that the node equipment to be networked is the effective node equipment, and obtaining an authentication result which is successfully authenticated.

a22, if the pre-stored device identification information consistent with the extracted identification information of the node device to be accessed exists in the pre-stored routing information table, determining that the node device to be accessed is an effective node device.
The extracted Mesh network identification information is compared with the pre-stored Mesh network identification information in the pre-stored routing information table to judge whether the extracted Mesh network identification information is consistent with the pre-stored Mesh network identification information in the pre-stored routing information table, if the extracted Mesh network identification information is consistent with the pre-stored Mesh network identification information in the pre-stored routing information table, the extracted identification information of the node device to be networked is further compared with the pre-stored device identification information in the pre-stored routing information table, and if the pre-stored device identification information which is consistent with the extracted identification information of the node device to be networked exists in the pre-stored routing information table, the node device to be networked is determined to be an effective node device, namely, the node device to be networked can be determined to belong to a node device of a Mesh network user, so that an authentication result which is successfully authenticated is obtained.
In addition, after the extracted Mesh network identification information is compared with the pre-stored Mesh network identification information in a pre-stored routing information table to determine whether the extracted Mesh network identification information is consistent with the pre-stored Mesh network identification information, if the extracted Mesh network identification information is inconsistent with the pre-stored Mesh network identification information, determining that the node device to be networked is an invalid node device, and listing the node device to be networked in a blacklist.
The extracted Mesh network identification information is compared with the pre-stored Mesh network identification information in the pre-stored routing information table to judge whether the extracted Mesh network identification information is consistent with the pre-stored Mesh network identification information in the pre-stored routing information table, if the extracted Mesh network identification information is inconsistent with the pre-stored Mesh network identification information in the pre-stored routing information table, the node device to be networked does not belong to the node device of the Mesh network user, the node device to be networked is judged to be an invalid node device, an authentication result of authentication failure is obtained, the node device to be networked is listed in a blacklist, and if the node device to be networked initiates a network access request again, authentication can be directly carried out according to the blacklist.
In addition, if the extracted Mesh network identification information is consistent with the pre-stored Mesh network identification information, after the extracted identification information of the node device to be networked is compared with the pre-stored device identification information in a pre-stored routing information table, if the pre-stored device identification information consistent with the extracted identification information of the node device to be networked does not exist in the pre-stored routing information table, the node device to be networked is determined to be an invalid node device, and the node device to be networked is listed in a blacklist.
After the extracted identification information of the node device to be accessed is compared with the prestored device identification information in the prestored routing information table, if the prestored device identification information consistent with the extracted identification information of the node device to be accessed does not exist in the prestored routing information table, the node device to be accessed is also indicated to not belong to the node device of the Mesh network user, the node device to be accessed is judged to be an invalid node device, so that an authentication result of authentication failure is obtained, the node device to be accessed is listed in a blacklist, and if the node device to be accessed initiates a network access request again, authentication can be directly carried out according to the blacklist.
In further implementations, it is also possible: and counting the network access request times of the same invalid node device within a preset time length, and if the counted times exceed a preset threshold value, generating alarm information to remind a Mesh network user.
That is, considering that even though the network access request of the illegal device is rejected, the network access request of the illegal device may still try to access the Mesh network continuously, in this embodiment of the present application, the network access request times of the same invalid node device within the preset time duration are counted, and if the network access request times of the same invalid node device within the preset time duration exceed the preset threshold, an alarm message is generated to remind the Mesh network user, for example, "there is frequent intrusion of an unknown device, please note |)! ", wherein, the preset duration and the preset threshold can be flexibly set according to the actual situation. Of course, the alarm information of different levels may also be generated according to the number of network access requests of the same invalid node device within a preset time duration, for example, if the number of network access requests exceeding a preset threshold is within a lower limit of a preset range, the alarm information of a low level is generated, such as "there is an unknown device intrusion, please note! "; if the number of the network access request times exceeds the preset threshold is within a preset range, generating a middle-level alarm message, such as "there is an unknown device frequently intruding, please note! "; if the number of the network access request times exceeds the preset threshold exceeds the upper limit value of a preset range, generating high-level alarm information, such as "there is unknown equipment frequently intruding, please check immediately! In this way, attention and maintenance of the Mesh network by the Mesh network user are brought, and therefore the safety of the Mesh network is improved.
