Embodiments of the present invention provide a wireless forwarding method, a main access point, and a forwarding access point. When the first device sends a downlink message to the second device, the main access point encapsulates the downlink message as a downlink tunnel message, and then passes the main access point The first wireless module of the access point sends to the second wireless module of the forwarding access point. After receiving the downlink tunnel message, the second wireless module verifies that the source address and destination address of the downlink tunnel message are legal and sends the downlink message to the second device without verifying the first device, the main access point, the forwarding access point, and the second device. Whether the four addresses corresponding to the second device are legal, thereby simplifying the addressing complexity in the data forwarding process. Secondly, the source address of the downlink tunnel message is the address of the first wireless module, and the destination address of the downlink tunnel message is the address of the second wireless module, so the downlink tunnel message will not expose the first device and the second device when it is transmitted in the wireless link. The address of the device, thus improving the security of data transmission.
Description
technical field [0001] Embodiments of the present invention relate to the field of wireless network communications, and in particular, to a method and apparatus for wireless forwarding. Background technique [0002] Before the invention of Wireless Local Area Networks (WLAN for short), if people wanted to communicate and communicate through the network, they had to use physical cables-copper stranded wires to form an electronic operation path. In order to improve efficiency and speed, later Optical fiber was invented. When the network develops to a certain scale, people find that this kind of wired network is very difficult to build, disassemble or re-layout and rebuild on the original basis, and the cost and cost are also very high, so the WLAN networking method came into being. WLAN The wireless local area network based on the IEEE802.11 standard allows wireless connection in the local area network environment using the 2.4GHz or 5GHz radio frequency band in the ISM freq...
