Abstract

The embodiment of the invention discloses a data packet forwarding method, device and system. The method comprises the following steps that the corresponding relationship between a user and a forwarding mode sent by an AC (access controller) is received; the corresponding relationship between the user and the forwarding mode is determined by the AC according to the forwarding mode corresponding to a user group; the forwarding mode comprises a local forwarding mode and an integrated forwarding mode; an uplink data packet is received, wherein the uplink data packet carries a user identifier; according to the user identifier, the uplink data packet is determined to be from a first user; the forwarding mode corresponding to the first user is determined according to the corresponding relationship between the user and the forwarding mode; the uplink data packet is forwarded according to the forwarding mode corresponding to the first user. The method, the device and the system provided by the embodiment of the invention have the advantages that the uplink data packet of the user is forwarded according to the forwarding mode corresponding to the user on an AP (access point), and the bandwidth bottleneck problem of the AC in the integrated forwarding mode can be avoided.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data packet forwarding method, device and system. Background technique [0002] A wireless local area network (WLAN for short) generally adopts a networking architecture of an access controller (AC for short) and an access point (AP for short). [0003] There are two forwarding modes in the AC and AP networking architecture, which are centralized forwarding mode and local forwarding mode; [0004] In the centralized forwarding mode, the data packets of the wireless users are sent by the AP to the AC through the control and provisioning of wireless access point (CAPWAP) tunnel between the AP and the AC, and then forwarded by the AC. [0005] In the local forwarding mode, the data packets of the wireless users are directly forwarded on the AP at Layer 2 without sending them to the AC for transit through the CAPWAP tunnel between the AP and the AC. [0006] At present, the netw...
