Embodiment Construction

[0028] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0029] The network elements described herein refer to elements in the network, for example, AC, AP, and SC mentioned below. Therefore, AC, AP, and SC may also be called AC network elements, AP network elements, and SC network elements.

[0030] image 3 It is a schematic diagram of basic networking of a WLAN control and service separation architecture according to an embodiment of the present invention. Figure 4 It is a logical relationship diagram among network elements according to an embodiment of the present invention.

[0031] Such as image 3 As shown in , the basic architecture includes multiple APs (AP1, AP2, AP3, AP4, AP5, AP6, AP7), multiple ACs (AC1, AC2, AC3, AC4), multiple service control servers SC (SC1, SC2 , SC3, SC4). exist image 3 In the example shown, SC2 (unified with AC1) is the backup SC for SC1 and SC4 (unified with AC4) is the ba...

Abstract

The invention provides a control and service separated WLAN framework and a configuration method thereof. The framework comprises a plurality of access points (AP), a plurality of access controllers (AC) and at least one service controller (SC) which is produced by the plurality of ACs after election campaign or assigned configuration; a data forwarding tunnel is established between the APs and the ACs, and a management tunnel is established between the ACs and the SC, and a management tunnel is established between the APs and the SC; and ACs are used for forwarding the data and the SCs are used for managing services.

Description

technical field [0001] The present invention relates to a WLAN architecture and a configuration method thereof, in particular to a WLAN architecture with separation of control and service and a configuration method thereof. Background technique [0002] As a standard in the WLAN field, the CAPWAP protocol has been officially released. RFC4118 (Architecture Taxonomy for Control and Provisioning of Wireless AccessPoints) defines several network elements based on CAPWAP in detail, and the relationship between each network element. [0003] Based on the CAPWAP protocol, there is a basic WLAN environment architecture: the access controller (AC) controls and configures the access point (AP) through the CAPWAP protocol. In the original protocol architecture, the management tunnel and data tunnel between the AC and the AP need to be established and processed at the same time, making the AC the only management and service exit of the entire system. [0004] According to the definit...
