Wireless bridge forwarding equipment and method

Abstract

The invention discloses wireless bridge forwarding equipment and method. The equipment comprises a wireless forwarding module and a wireless forwarding path storing module The method comprises the steps of: establishing a wireless forwarding path item by using a message source address as a destination address by the wireless forwarding module according to a source address and a source sending message of a received message and storing the wireless forwarding path item in the wireless forwarding path storing module; searching a corresponding wireless forwarding path item from the wireless forwarding path storing module according to the destination address of the message, forwarding the message according to the corresponding wireless forwarding path item; and storing the wireless forwarding path item by the wireless forwarding path storing module. According to the invention, under the conditions of no protocol overhead and no limit of network topology, the wireless message is forwarded by using an optimal forwarding path, and a loop is avoided.

Description

technical field [0001] The invention relates to forwarding equipment in the communication field, in particular to a wireless bridge forwarding equipment and method. Background technique [0002] In a communication network, when sending and receiving messages, forwarding by the bridge device is required. When the bridge device forwards the message, it will determine the next bridge device or the receiving end to forward according to the source address and destination address in the message header of the received message. [0003] With the development of communication technology, the application of wireless communication network is becoming more and more extensive. In the wireless communication network, wireless bridging and forwarding devices appear. Wireless bridging and forwarding devices have similar functions to wired bridging devices, such as Ethernet bridging devices. The main difference is that when wireless bridging and forwarding devices forward packets, their forwa...

Problems solved by technology

However, this method also has disadvantages, that is, once the wireless distribution system is established and the static path forwarding entries of each message are set for the wireless bridge forwarding device, the wireless distribution system cannot be expanded and redundancy cannot be provided. The packet path caused the problem of limited network topology, and the requirements for configuration and management of operators are also very high

[0011] The second method is to configure the spanning tree protocol in each wireless bridge forwarding device in the wireless distribution system, that is, to configure the spanning tree protocol on the wireless forwarding port of each wireless bridge forwarding device. According to the spanning tree protocol, the wireless bridge When the forwarding device forwards the message, it can judge whether there is a loop in the forwarded message path, and directly forward the message to the next wireless bridge forwarding device or receiving end. However, this method increases the protocol of the wireless bridge forwarding device. Overhead and needs to be configured for each wireless bridge forwarding device, increasing the complexity of configuration

[0012] To sum up, when the wireless bridging and forwarding devices in the current wireless distribution system forward packets, there are problems of limited network topology and protocol overhead.
