A message forwarding method and device

Abstract

The present invention provides a message forwarding method and device, wherein the method includes: the access point AP receives the first message sent by the wireless terminal, searches the forwarding table to obtain the layer 2 tunnel port for forwarding the first message, and sends the first message After tunnel encapsulation, the packet is sent to the switch assigned by the AC to the AP through the Layer 2 tunnel corresponding to the Layer 2 tunnel port, so that the switch sends the first packet to the destination device; or, the AP receives the second packet sent by the switch through the Layer 2 tunnel. The second message is a message sent by the destination device to the wireless terminal, and the second message is decapsulated through the tunnel and then forwarded to the wireless terminal according to the forwarding table. The invention realizes improving message forwarding performance while reducing network configuration amount.

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 (Access Point, referred to as: AP) on the wired network. It can be an AP or a wireless Controller (Access Controller, referred to as: AC). When terminating at the AP, the forwarding information for forwarding data needs to be configured on switches...

AI Technical Summary

Problems solved by technology

When terminating at the AP, the forwarding information for forwarding data needs to be configured on switches of each layer of the wired network, and the configuration workload is heavy; when terminating at the AC, the amount of network configuration can be reduced, but a large amount of data is forwarded by the AC Traffic, the forwarding performance of the AC cannot meet the requirements
