Wireless forwarding method, main access point and forwarding access point

Abstract

Embodiments of the invention provide a wireless forwarding method, a main access point and a forwarding access point. When a first device sends a downlink message to a second device, the main access point encapsulates the downlink message as a downlink tunnel message, and then the downlink tunnel message is sent to the forwarding access point through a first wireless module of the main access point. After a second wireless module receives the downlink tunnel message, the downlink message is sent to the second device when a source address and a destination address of the downlink tunnel messageare verified to be legal, and the legality verification of four addresses corresponding to the first device, the main access point, the forwarding access point and the second device is not needed, sothat the addressing complexity in a data forwarding process is simplified. Secondly, the source address of the downlink tunnel message is the address of the first wireless module, and the destinationaddress of the downlink tunnel message is the address of the second wireless module, so that the address of the first device and the address of the second device cannot be exposed when the downlink tunnel message is transmitted in a wireless link, and thus the safety of data transmission is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of wireless network communication, and in particular, to a method and device for wireless forwarding. Background technique [0002] Before the invention of Wireless Local Area Networks (WLAN for short), if people wanted to connect and communicate through the network, they had to use physical cables-copper twisted wires to form an electronic running path. Fiber optics were invented. When the network develops to a certain scale, people find that it is very difficult to set up, disassemble, or re-layout and rebuild the wired network on the original basis, and the cost and price are also very high, so the WLAN networking method Came into being. WLAN based on the IEEE802.11 standard wireless local area network allows wireless connection in the local area network environment using the 2.4GHz or 5GHz radio frequency band in the ISM frequency band that does not need to be authorized. WLAN has many...
