Embodiment Construction

[0079] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0080] The embodiment of the present invention provides a method for message transmission, and the method can be applied to a scenario where an AC broadcasts an ARP request message. Such as figure 1 As shown, it is an example diagram of a network system provided by an embodiment of the present invention, and the system includes: AC, an access switch, AP1, AP2, terminal 1, terminal 2 and terminal 3. Among them, the AC is connected to AP1 and AP2 through the ac...

Abstract

A method comprises: an AC receiving a first address resolution protocol (ARP) request packet to be broadcasted, the first ARP request packet carrying a first wireless payload; determining a target virtual BSS interface corresponding to a VLAN to which the first ARP request packet belongs and a target AP covering the target virtual BSS interface; modifying a prestored second ARP request packet according to the first wireless payload of the first ARP request packet and prestored encapsulation information, the encapsulation information comprising radio frequency information of the target virtual BSS interface and next-hop address information corresponding to the target AP; and transmitting the modified second ARP request packet to the target AP. The present invention can enhance processing efficiency of an AC.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for message transmission. Background technique [0002] At present, in the wireless network networking between the access controller (English: Access Controller, AC for short) and the access point (English: AccessPoint, AP for short), the AC will establish and maintain at least one virtual basic service set for the AP. (English: Basic Service Set, referred to as: BSS) interface. Wherein, the aforementioned virtual BSS interfaces may belong to the same virtual local area network (English: Virtual Local Area Network, VLAN for short), or may belong to different VLANs. [0003] When the AC receives the first address resolution protocol (English: Address Resolution Protocol, ARP) request message sent by the sender in a VLAN, for each virtual BSS interface in the VLAN, the AC will The ARP request message is copied, and then the first ARP req...
