Wireless network communication method, system and device based on spanning tree protocol (STP)

Abstract

The invention discloses an application method of a spanning tree protocol (STP) in a wireless network, which is used for solving the problem that in the wireless network, the control of the AP to the message forwarding state of a port based on the STP affects the message transmission between the AP and other AP. The method comprises the following steps: receiving a BPDU message sent from a second AP by a first AP; sending the message to a virtual interface corresponding to an MAC address according to the MAC address information of the second AP and the virtual interface corresponding to the MAC address information; and controlling the message forwarding state of the virtual interface based on the STP according to the message received by the virtual interface. The invention also discloses an application device of the STP in the wireless network. In the scheme provided by the invention, because the AP establishes the corresponding virtual interface based on the connection between the AP and other AP, the message forwarding state of each virtual interface can be controlled so that the message transmission between the AP and other AP can not be affected.

Description

technical field [0001] The present invention relates to the technical field of wireless networks, in particular to a wireless network communication method, system and device based on Spanning Tree Protocol (Spanning Tree Protocol, STP). Background technique [0002] The wireless bridge can implement interconnection at the link layer of a local area network (Local Area Network, LAN), and can implement storage and forwarding of messages. The wireless bridge can be used to connect devices located in different independent network segments, and has the advantages of high transmission power, long transmission distance, and strong anti-interference ability. A wireless access point (Access Point, AP) can implement the function of a wireless bridge. [0003] The connection modes between wireless bridges include: point-to-point connection, point-to-multipoint connection, and relay connection. figure 1 It is a schematic diagram of the connection structure when the wireless bridge ado...
