Optionally, in a specific implementation, one forwarding access point may also be connected to a plurality of second devices.
Based on the system architecture shown in fig. 1, as shown in fig. 2, an embodiment of the present invention provides a method for wireless forwarding, which includes the following steps in a downlink direction, that is, in a direction in which a first device sends a downlink message to a second device:
step S201, the master access point receives a downlink message sent by the first device to the second device, where a source address of the downlink message is an address of the first device, and a destination address of the downlink message is an address of the second device.
Step S202, the main access point determines the number of the forwarding access point corresponding to the second device and the address of the second wireless module in the forwarding access point according to the address of the second device.
Step S203, the main access point packages the downlink message as a downlink tunnel message, the downlink tunnel message at least comprises a source address, a destination address, a number of the forwarding access point and a protocol type, the source address of the downlink tunnel message is the address of the first wireless module of the main access point, and the destination address of the downlink tunnel message is the address of the second wireless module.
And step S204, the main access point sends the downlink tunnel message to the second wireless module according to the source address and the destination address of the downlink tunnel message and the carried number and the protocol type of the forwarding access point.
Step S205, the second wireless module of the forwarding access point receives the downlink tunnel message sent by the first wireless module.
Step S206, when the forwarding access point determines that the source address, the destination address, the number of the forwarding access point and the protocol type in the downlink tunnel message meet the preset conditions, the forwarding access point decapsulates the downlink tunnel message to obtain the downlink message.
Step S207, the forwarding access point sends the downlink message to the second device.
Specifically, in step S201, the master access point receives a downlink message sent by the first device to the second device through the first conversion module.
In steps S202 to S204, the first conversion module queries an index table according to the address of the second device, and if the index table does not have the number of the forwarding access point corresponding to the second device and the address of the second wireless module in the forwarding access point, it indicates that the address of the second device is not bound to the master access point, and flooding needs to be performed, where the specific process is as follows: the method comprises the steps of copying downlink messages according to the number of forwarding access points accessed to a main access point, respectively packaging each copied downlink message into an initial downlink tunnel message, wherein the packaged initial downlink tunnel message at least comprises a source address, a destination address, the number of the forwarding access point and a protocol type. The number of the forwarding access point is uniquely allocated by the main access point when the forwarding access point accesses, the protocol type is a preset special protocol type, the protocol type is used for fixedly identifying the downlink tunnel message and does not conflict with the traditional TCP/IP protocol type, and meanwhile, the downlink tunnel message can be correctly identified by the forwarding access point. When encapsulating the downlink message, encapsulating different destination addresses and numbers of forwarding access points for different forwarding access points. The source address of the encapsulated initial downlink tunnel message is the address of the first conversion module, and the destination address is the address of the wireless module of the forwarding access point accessing the main access point. The first conversion module sends the initial downlink tunnel message to the first wireless module, then the first wireless module modifies the source address stored in the tunnel head into the address of the first wireless module to obtain the downlink tunnel message, and finally the downlink tunnel message is respectively sent to the wireless modules of the forwarding access points accessing the main access point. Only one of the forwarding access points receiving the downlink tunnel message feeds back the uplink tunnel message. The main access point determines the corresponding relation among the address of the second device, the address of the second wireless module in the forwarding access point and the number of the forwarding access point according to the fed-back uplink tunnel message, and then stores the corresponding relation in the index table, thereby realizing the binding between the address of the second device, the number of the forwarding access point and the address of the second wireless module in the forwarding access point.
If the index table has the number of the forwarding access point corresponding to the second device and the address of the second wireless module in the forwarding access point, the downlink message is encapsulated into an initial downlink tunnel message according to the number of the forwarding access point and the address of the second wireless module in the forwarding access point, which are inquired from the index table, and the encapsulated initial downlink tunnel message at least comprises a source address, a destination address, the number of the forwarding access point and a protocol type, wherein the source address is the address of the first conversion module, the destination address is the address of the second wireless module inquired from the index table, and the number of the forwarding access point is the number of the forwarding access point inquired from the index table. The first conversion module then sends the initial downlink tunnel message to the first wireless module. The first wireless module modifies the source address of the initial downlink tunnel message into the address of the first wireless module to obtain the downlink tunnel message, and then sends the downlink tunnel message to the second wireless module of the forwarding access point.
In steps S205 to S207, after the second wireless module of the forwarding access point receives the downlink tunnel message, it is determined whether a source address, a destination address, a number of the forwarding access point, and a protocol type in the downlink tunnel message meet preset conditions, if yes, the second wireless module of the forwarding access point modifies the destination address of the received downlink tunnel message to be a second conversion module of the forwarding access point, and sends the modified downlink tunnel message to the second conversion module. And the second conversion module decapsulates the modified downlink tunnel message to obtain a downlink message, and then judges whether the destination address of the downlink message is the address of the second device, if so, the downlink message is sent to the second device, otherwise, the downlink message is discarded.
When the first device sends the downlink message to the second device, the main access point encapsulates the downlink message into the downlink tunnel message, wherein a tunnel header of the downlink tunnel message comprises a source address and a destination address of the downlink tunnel message, then the downlink tunnel message is sent to the second wireless module of the forwarding access point through the first wireless module of the main access point, and after the forwarding access point receives the downlink tunnel message, only the source address and the destination address of the received downlink tunnel message need to be judged whether legal or not, and whether four addresses corresponding to the first device, the main access point, the forwarding access point and the second device are legal or not does not need to be judged, so that the addressing complexity in the data forwarding process is simplified. And secondly, the source address of the downlink tunnel message is the address of the first wireless module of the main access point, and the destination address of the downlink tunnel message is the address of the second wireless module, so that the addresses of the first device and the second device are not exposed when the downlink tunnel message is transmitted in a wireless link, and the safety of data transmission is improved.
Based on the system architecture shown in fig. 1, as shown in fig. 3, an embodiment of the present invention provides a method for wireless forwarding, where in an uplink direction, that is, in a direction in which a second device sends an uplink message to a first device, the method includes the following steps:
step S301, the forwarding access point receives an uplink message sent by the second device to the first device, wherein the source address of the uplink message is the address of the second device, and the destination address is the address of the first device.
Step S302, the forwarding access point packages the uplink message as an uplink tunnel message, the uplink tunnel message at least comprises a source address, a destination address, a number of the forwarding access point and a protocol type, the source address of the uplink tunnel message is an address of a second wireless module of the forwarding access point, and the destination address of the uplink tunnel message is an address of a first wireless module of the main access point.
Step S303, the forwarding access point sends the uplink tunnel message to the first wireless module according to the source address and the destination address of the uplink tunnel message and the carried number and the protocol type of the forwarding access point.
Step S304, the first wireless module of the main access point receives the uplink tunnel message sent by the second wireless module of the forwarding access point.
Step S305, when the main access point determines that the source address, the destination address, the number of the forwarding access point and the protocol type in the uplink tunnel message meet the preset conditions, the main access point decapsulates the uplink tunnel message to obtain the uplink message.
Step S306, the master access point sends the uplink message to the first device.
Specifically, in step S301 and step S302, the forwarding access point receives, through the second conversion module, an uplink message sent by the second device to the first device, and then the uplink message is encapsulated by the second conversion module as an initial uplink tunnel message, where the initial uplink tunnel message at least includes a source address, a destination address, a number of the forwarding access point, and a protocol type. In a specific implementation, the source address and the destination address of the initial uplink tunnel message, and the number and the protocol type of the forwarding access point that are carried in the initial uplink tunnel message may be stored in the tunnel header of the initial uplink tunnel message, where the source address of the initial uplink tunnel message is the address of the second conversion module, and the destination address is the address of the first wireless module. The initial uplink tunnel message is then sent by a second conversion module of the forwarding access point to a second wireless module.
In step S303, before the forwarding access point sends the uplink tunnel message to the first wireless module through the second wireless module, the second wireless module of the forwarding access point modifies the source address of the initial uplink tunnel message into the address of the second wireless module, so as to obtain the uplink tunnel message. In specific implementation, the second wireless module modifies the source address stored in the tunnel header into the address of the second wireless module, and obtains the uplink tunnel message.
In step S304 and step S305, after receiving the uplink tunnel message sent by the second wireless module of the forwarding access point, the first wireless module of the main access point determines whether a source address, a destination address, a number of the forwarding access point, and a protocol type in the uplink tunnel message meet preset conditions, if yes, the first wireless module modifies the destination address of the uplink tunnel message to be the first conversion module, and sends the modified uplink tunnel message to the first conversion module.
