AI Technical Summary

Problems solved by technology

In order to determine the packet forwarding mode based on the SSID, multiple SSIDs must be configured on the AP, and each SSID must be configured with a corresponding forwarding mode, and the user needs to be notified in advance to connect to the corresponding SSID, which increases the complexity of network configuration and maintenance.

Embodiment 1

[0048] image 3 A schematic flow chart of a message forwarding method provided in the embodiment of this application, the message forwarding method can be applied to figure 1 or figure 2 In the network system shown.

[0049] see image 3 The message forwarding method includes:

[0050] S300. The wireless controller obtains the message to be forwarded, and determines the characteristics of the message to be forwarded.

[0051] The wireless controller receives the packets to be forwarded sent by other network devices, and determines the characteristics of the packets to be forwarded.

[0052] Wherein, the feature of the message to be forwarded includes the source address of the message to be forwarded, and the wireless controller obtains the source address of the message to be forwarded after obtaining the message to be forwarded. The source address of the message to be forwarded is the address of the network device.

[0053] In the embodiment of the present application, ...

Embodiment 2

[0083] An embodiment of the present application provides a wireless controller, which is configured to perform the steps performed by the wireless controller in the above message forwarding method. The wireless controller provided in the embodiment of the present application may include modules corresponding to corresponding steps.

[0084] In the embodiment of the present application, the wireless controller may be divided into functional modules according to the above method examples. For example, each functional module may be divided corresponding to each function, or two or more functions may be integrated into one processing module. The above-mentioned integrated modules can be implemented in the form of hardware or in the form of software function modules. The division of modules in the embodiment of the present application is schematic, and is only a logical function division, and there may be other division methods in actual implementation.

[0085] In the case of div...

Abstract

A Packet forwarding method and device relates to the field of communication technology and reduces complexity in network configuration and maintenance. The method includes that a wireless controller determines a packet forwarding method corresponding to features of to-be-forwarded packets according to a forwarding strategy, wherein the forwarding strategy includes the corresponding relation of thefeatures of the to-be-forwarded packets and packet forwarding methods, the features of the to-be-forwarded packets include source addresses of the to-be-forwarded packets and the values of the packetforwarding methods are a tunnel forwarding method or a local forwarding method; and a wireless controller forwards the to-be-forwarded packets according to the packet forwarding method.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a message forwarding method and device. Background technique [0002] In a wireless local area network (English: wireless local area network, WLAN) including a wireless controller (English: wireless controller) and an access point (English: access point, AP), the forwarding mode of the WLAN frame can be divided into tunnel forwarding mode and Local forwarding method. Wherein, the local forwarding mode is that the AP converts the WLAN frame into an Ethernet frame, and directly sends the Ethernet frame according to the address of the Ethernet frame. In the tunnel forwarding mode, the AP converts the WLAN frame into an Ethernet frame, and then uses the tunnel to send the Ethernet frame to the wireless controller. The WLC forwards the Ethernet frame. [0003] In a WLAN including a wireless controller and an AP, the wireless controller or the AP may determine a...
