The traditional method is to adopt an AC + FitAP mode to carry out wireless networking, and the functions of configuration, equipment monitoring, version upgrading and the like are issued in a unified mode through the AC. However, for home users, the wireless networking scale is small, and additionally, the purchase of the AC is an additional expense, which increases the use cost of the users.

The invention is further described below in conjunction with the appended drawings and the detailed description.

FIG. 1 is a diagram of a home appliance networking model according to an embodiment of the present invention.

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below by combining the specific drawings.

Aiming at the standard AC + FitAP networking, the scheme performs centralized power supply on the home decoration wireless AP through POE and uniformly bridges the home decoration wireless AP to the home outlet gateway through the network cable, so that a neighbor discovery and maintenance protocol mechanism between devices is simplified, a safety certification mechanism is weakened, and convenience is improved; in the configuration synchronization stage, a TCP transmission mechanism is adopted to ensure high reliability.

According to the principle, the scheme realizes zero-configuration networking and rapid configuration through the following management and control scheme.

The scheme realizes the quick discovery and the state maintenance of the neighbors in a multicast mode, and determines the master and slave wireless routers in the LAN.

Therefore, after the same type of equipment is powered on, each equipment can sense the whole network topology through the self-defined multicast neighbor discovery protocol. The user can conveniently log in any equipment through wireless association and can carry out configuration, and then the whole network configuration synchronization is carried out, so that the configuration workload of the user is reduced.

According to the scheme, through a two-dimensional code scanning mode, the handheld wireless terminal is quickly associated and logs in any wireless router to be configured of the local LAN.

The code scanning login configuration is carried out by adopting the mobile terminal equipment, and the LAN is not required to be connected through a PC (personal computer) in the prior art, so that the convenience and the efficiency of the configuration operation are greatly improved.

In addition, the scheme enables a user to log in a management configuration interface of the two-layer bridging wireless device through a wireless air interface in an Ebtable redirection mode. Specifically, each ip message with the destination address as the management address received from the LAN side in the bridge is checked through the Ebtable rule, and the destination mac address of the message is modified to be the bridge mac address, so that the message which should be forwarded can be received by the device for local processing. The premise is to ensure that both the user terminal and the device can obtain the addresses of the same network segment from the gateway, so that the device and the terminal can communicate with each other.

In the scheme, the current master integrally stages the wireless routing equipment of the whole LAN, so that simple load balancing is realized. If the current master fails, a neighbor maintenance protocol is needed to reselect one master according to the priority to carry out configuration distribution management and control and flow balance management and control. So as to deal with the subsequent network-accessing similar equipment.

On the basis, the scheme reliably distributes the configuration parameters of the current master device to the slave devices.

The configuration synchronization adopts wget based on a TCP protocol, the synchronization content is issued by configuration packaging, and the target opportunity of receiving the configuration can re-cover parameters related to the uniqueness of the equipment, such as MAC, serial number and the like, so that the consistency of the configuration of a plurality of pieces of equipment is ensured.

And before configuration synchronization is issued, the master and the slave need to perform configuration consistency comparison, and if the configuration of the current slave is consistent with that of the master, the master is prompted to be configured without issuing so as to reduce the synchronous burden of the master.

According to the scheme, any equipment which logs in last can be promoted to a master under the trust of the user to control configuration distribution and load balancing scheduling, so that what you see is what you get is realized, and convenience is greatly improved.

The above solution is specifically described below by a specific application example.

Referring to fig. 1, a diagram of common application deployment of home decoration networking is shown. When the scheme is applied, each wireless router W12C is connected to a POE switch, and is powered by the POE switch. And then the POE switch is connected with the home gateway. And the POE switch with the network management and the routing is controlled, so that the on-off control and the power switch control of a certain W12C router can be implemented.

Aiming at the home decoration networking with zero configuration, the embodiment can realize rapid configuration through the handheld intelligent equipment.

In order to facilitate quick association of the handheld device, the device leaves a factory and adopts a bridge connection mode by default, and each device has a wireless SSID (service set identifier) which is related to the serial number of the device and is used as a first association wireless signal.

The wireless bridged WAN port adopts a DHCP client mode to acquire a dynamic IP address from the home gateway so as to ensure that the WAN ports of all home wireless routers are in the same network segment.

Meanwhile, the WAN port performs neighbor discovery using the customized private multicast group 239.1.1.1 and maintains a neighbor state.

Therefore, the mode that the handheld intelligent device scans codes to log in a WAP configuration interface can be adopted, and the problems of complexity and credibility in APP installation can be avoided.

The WYSIWYG master/slave mode can be implemented throughout the home networking. The wireless router which the user logs in each time can be upgraded to the current maximum value by the neighbor priority of the wireless router under the trust of the user, and the wireless router serves as the master of the current bridge network. Any configuration on the device will unconditionally synchronize all onto the slave device. To ensure that the synchronization effect is seen on the current device, the slave of the current network must all complete the configuration synchronization, and the master itself restarts the local wireless service. Otherwise, the handheld terminal loses contact with the master in the configuration process, and re-association is needed, so that the user experience is affected.

If the master down machine is currently in use, the neighbor maintenance protocol selects a new master from wireless routers in the current network.

All the devices inform the master of the number of the STAs, the uplink and downlink flow and the signal intensity of the devices, and the report is generated by the generator; meanwhile, the master calculates locally and comprehensively according to the signal intensity, the channel and the flow, and informs the balance of the number of slave access users, so as to realize simple load balance.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
