Gateway Device Automates AC Address Selection for Wireless Access Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual configuration of access controller (AC) addresses on wireless access points (APs) is complex and error-prone, reducing efficiency and reliability in obtaining AC addresses, especially when AC addresses change or faults occur.
Innovation Solution
A gateway device receives requests from APs, selects a suitable AC based on working state and service processing capability, and sends the AC's address to the AP, enabling the establishment of a CAPWAP tunnel, thereby automating the address configuration process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual configuration of AC address on AP is performed, then the AP can establish CAPWAP tunnel with AC, but the operation becomes complex and error-prone, reducing efficiency and reliability
Solution Approach 1:
The gateway device serves as an intermediary between the AP and AC. When the AP needs to obtain the AC address, it sends a request to the gateway, which then provides the address information to the AP. This intermediary mechanism eliminates the need for manual configuration on the AP while ensuring reliable address acquisition, directly resolving the contradiction between operational simplicity and reliability.
2Productivity
If manual address reconfiguration is performed on AP when AC address changes or fault occurs, then the AP can reconnect to AC, but frequent manual operations are required, reducing efficiency
Solution Approach 1:
The system enables self-service functionality where the AP automatically obtains AC address information from the gateway device without requiring manual intervention. When AC address changes or faults occur, the AP can autonomously request and receive updated address information, eliminating the need for repeated manual reconfiguration operations and significantly improving reconfiguration efficiency.
Solution Approach 2:
The gateway device pre-configures and maintains the AC address information, preparing it in advance for potential AP requests. This preliminary preparation ensures that when the AP needs to connect or reconnect, the address information is already available at the gateway, enabling rapid automated provision without manual intervention.
3Reliability
If manual configuration is used, then the AP can obtain AC address, but human errors frequently occur during configuration, reducing reliability
Solution Approach 1:
The gateway device acts as a centralized intermediary that manages AC address information. Instead of relying on manual configuration at the AP level, the gateway provides the authoritative address information to the AP through automated protocols. This eliminates human error in the configuration process while maintaining full automation of address acquisition.
Solution Approach 2:
The system implements a feedback mechanism where the AP sends requests to the gateway for address information, and the gateway responds with the current AC address. This automated feedback loop ensures that the AP always receives accurate, up-to-date address information without manual intervention, significantly improving configuration reliability while maximizing automation.

AI summary
Embodiments of the present invention relate to an address processing method, a gateway device, and an access point. An access point sends a request message to a gateway device. The access point obtains an address of an access controller from the gateway device. The address of the access controller is an address of an access controller selected by the gateway device. The access point establishes a CAPWAP tunnel with the access controller selected by the gateway device.
