Wireless network gateway access method based on multi-board-card ATCA

Abstract

The invention discloses a wireless network gateway access method based on multi-board-card ATCA. The method refers to a wireless controller, the wireless controller is provided with a main control panel and a plurality of service boards, and the main control panel is provided with a DHCP server. The access method includes the following steps that each pure AP which will have access sends a DHCP request to the DHCP server; IP addresses of all service boards connected with the AP are put into DHCP responses by the DHCP server; access requests are initiated to all the service boards in the DHCP responses, and priorities and load information are put into connection response messages after the access requests are received by the service boards; a service board which the pure AP intends to have access to is selected according to the priorities of access response messages, the load information and the sequence of the moments when the access response messages are received. By means of the wireless network gateway access method based on the multi-board-card ATCA, pressure of the main control panel can be alleviated, and the access efficiency and reliability of the pure APs are improved.

Description

technical field [0001] The invention relates to a method for accessing a wireless gateway AP, in particular to a method for accessing a wireless gateway based on an ATCA multi-card architecture. Background technique [0002] In an ATCA (Advanced Telecom Computing Architecture, advanced communication computer architecture) wireless controller system, a typical wireless controller component includes: a main control board, multiple service boards, and a switch board. A wireless access point (AP, Access Point) is also called a wireless bridge or a wireless gateway, which is a so-called "thin" AP, also known as a pure AP. The transmission mechanism of this wireless device is equivalent to the hub in the wired network, which continuously receives and transmits data in the wireless LAN; any PC equipped with a wireless network card can share the resources of the wired LAN or even the wide area network through the AP. The so-called "fat" AP in the industry should be called a wireles...

AI Technical Summary

Problems solved by technology

[0003] Under the thin AP (AP: Access Point, centralized management architecture) architecture, there is usually a main control board responsible for the management of the wireless controller. When the number of APs connected to the wireless controller increases greatly, the main control board is likely to form a bottleneck of management capabilities, resulting in performance problems such as untimely response of the wireless controller and packet loss.
