Problems solved by technology

[0013] However, the first solution brings a lot of inconvenience in the current network. Before the equipment is upgraded, the AP and the layer 2 network in the general area have been deployed.
The downlink layer 2 network often has only one VLAN, so the traffic distribution of this scheme cannot be realized.
[0014] In the second solution, the AP traffic is randomly allocated to different service processing boards, which cannot guarantee accurate load sharing, and at the same time, the AC cannot fully control the AP.
This solution is generally not recommended in the live network

Embodiment Construction

[0053] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0054] figure 1 A structural diagram of a whole machine of a device for sharing load between user service boards of a rack-mounted wireless controller according to an embodiment of the present invention is illustrated as an example.

[0055] Such as figure 1 As shown, the present invention is implemented by setting a distribution module on the interface board of the AC, and the wireless user traffic entering the AC first reaches the interface board when going up, and then enters the distribution module at the interface board. The distribution module performs high-speed, high-accuracy matching and reconstruction of data frames, so that the output traffic is added to different 802.1Q VLAN tags, and then enters the main control boar...

Abstract

The invention discloses a sharing method and device of load between user service boards of a rack-mounted wireless controller. The method comprises the following steps of: S1, carrying out shunt control on received upstream flow by an interface board, and intercepting relevant field information in a data frame; S2, calculating the intercepted relevant field information according to a shunt rule designed by users; S3, reconstructing the data frame according to the calculating result, modifying the corresponding field of the message or adding additional user-defined identification, so that the upstream flow entering the interface board meets the shunt condition; and S4, carrying out shunt control on the upstream flow to be transmitted by the interface board. By adopting the sharing method and device, wireless services with the same virtual local area network (VLAN) identification can be flexibly shunted into different service processing boards in the stand, so that single IP downstream of the whole unit is realized, and the user service load can be shared.

Description

technical field [0001] The invention relates to the field of electronic communication, in particular to a method and device for sharing load between user service boards of a rack-type wireless controller. Background technique [0002] In order to understand the present invention more clearly, some technical terms commonly used in this field are firstly explained. [0003] Interface board: The rack-mounted wireless controller has a unified external interface, which provides physical interfaces for the ingress and egress of uplink and downlink traffic, and is responsible for data forwarding, service distribution, and other functions. [0004] Service board processing board: The single board in the rack-mounted wireless controller responsible for service processing. With high-performance multi-core processors and high-speed memory, it provides powerful business processing capabilities and is the core of the whole machine's business processing. [0005] Wireless Access Point (...
