Configuration acquiring method, zero configuration access point and neighbor access point

Abstract

The invention discloses a configuration acquiring method, a zero configuration access point and a neighbor access point. The configuration acquiring method comprises the following steps of: A1, discovering neighbor APs (Access Points) through scanning by a first AP in a zero configuration state, sequentially selecting one neighbor AP from the neighbor APs, and reporting a first AP identifier to the selected neighbor AP so that the neighbor AP forwards the first AP identifier to an AC (Access Controller) related to the neighbor AP and the AC determines whether the first AP is permitted to be associated or not according to the first AP identifier; B1, when the first AP receives an association permitted indication which is forwarded from the neighbor AP and comes from the AC, establishing a CAPWAP (Control And Provisioning of Wireless Access Points) channel with the AC, and acquiring self configuration from the AC through the CAPWAP channel; and when the first AP receives an association refused indication sent from the neighbor AP, forwarding to the next neighbor AP; and returning to the step A1. The speed of the zero configuration AP for acquiring the configuration is increased by adopting the invention.

Description

technical field [0001] The invention relates to the technical field of data configuration, in particular to a configuration acquisition method, a zero-configuration access point, and a neighbor access point. Background technique [0002] Controlling and Provisioning of Wireless Access Point (CAPWAP) is a communication protocol between an access point (AP, Access Point) and an access controller (AC, Access Controller). CAPWAP in an IP network Use User Datagram Protocol (UDP, User Datagram Protocol) as the bearer protocol; CAPWAP protocol is the main tool for AC to manage APs and APs to forward data. [0003] Mesh (MESH) technology is a media access control (MAC, Media Access Control) layer technology defined in the International Institute of Electrical and Electronics Engineers (IEEE, The Institute of Electrical and Electronic Engineer) P802.11s draft. 802.11 Wireless Local Area Network (WLAN, Wireless Local Area Network) MAC technology supplement. The wireless Mesh network...

Problems solved by technology

[0017] from figure 2 It can be seen from the flow shown that in order to obtain its own configuration, AP0 in the zero-configuration state needs to establish temporary Layer 2 links with neighboring APs in the neighbor list one by one. The operation of the channel, so that AP0 may have to establish temporary links with multiple neighboring APs, and try to establish a CAPWAP channel before finding an AC that can download the configuration. The process of establishing a CAPWAP channel involves obtaining an IP address and testing AC support. Whether the IP address is an IPv4 or an IPv6 address, etc., will cause AP0 to enter the working state for a long time, sometimes more than 10 minutes
