Embodiment Construction

[0029] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, the network architecture applicable to the embodiments of the present invention will be briefly described below.

[0030] See figure 1 , which is a schematic structural diagram of a message forwarding system provided by an embodiment of the present invention, as shown in figure 1 As shown, the packet forwarding system includes a stack formed by multiple ACs and a switching device, and the stack is connected to the switching device through an aggregation link.

[0031] exist figure 1 In the packet forwarding system shown, the stacked master device can issue a filter table for instructing packet forwarding to the switching device, so that the switching device will pass the packets sent to the AC side that match the The port to which the device is connected reduces the packet forwarding on the stack link between stack member devices and im...

Abstract

The invention provides a packet forwarding method and a packet forwarding device. The method comprises: when the AC is the master device of the stack, and receives the first discovery request packet of the access point AP, generating a first filtering entry corresponding to the AP; and issuing the first filtering entry to the switching device, so that the switching device sends the first packet matched with the first filtering entry to the AC through the first target port in the port corresponding to the aggregated member port information included in the first filtering entry. The embodimentsof the invention may reduce the packet forwarding of the stack links between the stack member devices and improve the reliability of the stack links.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a message forwarding method and device. Background technique [0002] In a large-scale WLAN (Wireless Local Area Network, wireless local area network) network, multiple ACs (Access Controllers, access controllers) are usually required to manage a large number of APs (Access Points, access points). It is difficult to manage each AC independently, and a single A failure of an AC device will interrupt the service of the wireless network connected to it. [0003] In order to solve the above problems, multiple ACs can be stacked, such as IRF (Intelligent Resilient Framework, Intelligent Resilient Framework), which can not only ensure the unified management and information backup of APs, but also ensure that when an AC fails, the AP can be kept online and Wireless service is uninterrupted. [0004] After the service physical links on the member devices in the stack are...
