Embodiment Construction

[0031] The message forwarding method in the embodiment of the present invention is applied to a WLAN network, and is used to describe how an AP forwards a message from a wireless terminal to a destination device when it receives a message from a wireless terminal, and how the AP forwards a message sent from a destination device to a wireless terminal. figure 1 An optional network architecture of the method is illustrated, and the packet forwarding method of the embodiment of the present invention is described in conjunction with the network architecture, but it should be noted that the method of the embodiment of the present invention is still applicable to networks of other architectures .

[0032] like figure 1 As shown, the network includes: wireless terminal 11, and assuming that the IP address of the wireless terminal is 192.168.0.2, the wireless terminal is connected to AP12, and can send data in wireless format to AP12, and AP12 can convert the received wireless data A...

Abstract

The invention provides a packet forwarding method and device. The method comprises the steps that an access point (AP) receives a first packet sent by a wireless terminal; a forwarding table is looked up to acquire a two-layer tunnel port for forwarding the first packet; the first packet after tunnel encapsulation is sent to a switch distributed by AC to AP through a two-layer tunnel corresponding to the two-layer tunnel port, and the switch sends the first packet to a destination device; preferably, the AP receives a second packet sent by the switch through the two-layer tunnel; the second packet is a packet sent by the destination device to the wireless terminal; and the second packet after tunnel decapsulation is sent to the wireless terminal according to the forwarding table. According to the invention, the amount of network configuration is reduced, and the performance of packet forwarding is improved.

Description

technical field [0001] The present invention relates to a wireless local area network (Wireless Local Area Networks, WLAN for short) network technology, in particular to a message forwarding method and device. Background technique [0002] In the actual deployment of the WLAN network, the WLAN network must be attached to the wired network, that is, the data plane in the WLAN network is responsible for forwarding packets to wireless users, and ultimately relies on network devices in the wired network to send data to Destination address. In the above message forwarding process, a data termination device is involved. The data termination device is responsible for forwarding the data of the wireless user received by the access point (AccessPoint, referred to as: AP) in the wired network. It can be an AP or a wireless control device. Access Controller (AC for short). When terminating at the AP, the forwarding information for forwarding data needs to be configured on switches of...
