A message forwarding method, wireless access node, and system

Abstract

The invention discloses a message forwarding method, a wireless access point (AP) and a message forwarding system. The method comprises the following steps that: the wireless AP acquires a forwarding configuration table, wherein the forwarding configuration table comprises message types and forwarding modes; the wireless AP receives messages sent by a user station and acquires the message types of the messages; the wireless AP determines the forwarding modes of the messages according to the message types of the messages and the forwarding configuration table; and the wireless AP packages and forwards the messages according to the forwarding modes of the messages. By the method, the forwarding of wireless user messages can be controlled on the wireless AP, and the problems of the separation of an AP controller (AC) from wireless null interface control and user access control in a local forwarding mode and the bandwidth waste between the AP and the AC in a tunnel forwarding mode due to incapability of differently forwarding different wireless user messages by using the AP in different modes are solved.

Description

technical field [0001] The invention relates to the field of wireless access, in particular to a message forwarding method, a wireless access node and a system. Background technique [0002] The wireless access node (full name in English: Access Point, hereinafter referred to as: AP) is set in the wireless network, and the access authentication message and ordinary service message of the wireless user are forwarded through the AP, and the wireless access in the wireless network A node controller (English full name: AP Controller, hereinafter referred to as AC) is used to control the forwarding mode of access authentication messages and common service messages on the AP. [0003] The forwarding mode of the received wireless message on the AP includes the local forwarding mode and the tunnel forwarding mode. The local forwarding mode means that the AP encapsulates the received wireless message and generates the Ethernet message. The message is directly forwarded to the destin...

AI Technical Summary

Problems solved by technology

[0005] In the prior art, since the AP can only simply forward the received wireless packets, when the AP is configured in the local forwarding mode, all the packets are no longer sent to the AC. Control and user access control are separated; when the AP is configured in the tunnel forwarding mode, all wireless packets need to be forwarded to the AC first, resulting in waste of bandwidth between the AP and the AC
